Abstract: 356,206. Electric telegraphs. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. June 4, 1930, No. 17218. Convention date, June 7, 1929. [Class 40 (iii).] Connections in either direction between remote stations UV,UV1, &c. and telegraph sets ASch, BSch, &c. at a main station HV are made by relays F under control of sluggish relays T1, T2, &c. individual to the remote stations. Normally the T relays are all energized in series with the recording magnets EM at the respective remote stations over kevs S1 &c. and back contacts of the F relays and of Ka. Call from remote station. Momentary depression of key AT de-energizes T1 which energizes the first F1 relay corresponding to an available connection. If the first main-station set ASch is idle (and La therefore de-energized) the first relay F1a is energized, lights busy lamps L1, L2, L3, locks over its second winding in series with La, reenergizes T1, and connects the calling line to magnet EM1 of ASch, which records the message sent by the key Sk. At the end of the message the connection is unlocked by key 0. Starting and stopping telegraph motors. The motors are started by a momentary de-energization of magnets EM, EM1 and stop only after a prolonged energization of these magnets. At the remote station the starting impulse is due to the momentary depression of AT. At the main station, EM1 is normally energized but is momentarily de-energized when La pulls up. All main-station sets busy. In this case, La, Lb, Lc being all energized, lamps B1A, B1B, B1C are lit. Changing priority of main-station sets. If key Sch1 is thrown the first call to arrive is delivered to BSch. Call to remote station. A switch such as S1 individual to the wanted station and to an idlemain station set is momentarily pressed, deernergizing T1 and energizing Ma, which jointly energize Flat to complete the wanted connection Ma being unlocked by La. Calls to groups of remote stations. Momentary depression of a key such as GaA energizes Ka, Ma. Relay Kade-energizes T1, T2, T3 to energize F1a, F2a, F3a which lock in series with La, which locks Ka and unlocks Ma. A message sent by key Sk1 is repeated by polarized relays Pa, Sa to a circuit which is connected by Ka to stations UV, UV1, UV2 in parallel. A key such as GbA operates Kb instead of Ka to connect a different group of remote stations, while a key such as GcA operates both Ka and Kb to connect both groups. A meter M at the remote station shows whether the line circuit is open (out of order), or normally closed through T1, or connected to a main-station set.

Title: Improvements in and relating to coating fluorocarbon materials with metal
Inventor: TORDAY LASZLO
IPC: B32B15/08
Filed: 1958-05-30
Abstract: A thin layer of metal is formed on a carrier, from which it can subsequently be parted relatively easily, and then transferred to a fluorocarbon material surface (see Group VIII).  The carrier may be of a malleable metal that does not oxidize at the sintering temperature of the fluorocarbon material, e.g. of aluminium, or of a material that will volatilize without trace at that temperature, e.g. an acrylic resin, and may be so prepared, e.g. by more or less polishing, as to impart desired surface characteristics to the metal layer.  The metal layer may be of copper, brass, nickel or zinc, and may be formed by spraying on to the carrier.  The sprayed metal layer may be impregnated with a P.T.F.E. emulsion.ALSO:A fluorocarbon material is coated with metal by forming a thin layer of metal on a carrier, from which the metal can susequently be parted relatively easily, and transferring the metal layer to a fluorocarbon material surface by moulding the fluorocarbon material under pressure against the metal layer.  The fluorocarbon material may be polytetrafluoroethylene or polytrifluorochloroethylene.  The carrier may be of a malleable metal that does not oxidise at the sintering temperature, e.g. aluminium, or of a material that will volatilise without trace at that temperature, e.g. an acrylic resin, and may be so prepared, e.g. by polishing, as to impart desired surface characteristics to the metal layer.  The metal layer may be of copper, brass, nickel or zinc, and may be formed by spraying on to the carrier.  The fluorocarbon material may be moulded from powder form, with or without fillers, e.g. glass powder, asbestos powder, fibres or pigments; strata of different grades may be used, e.g. powder of finer particle size than the remainder may be provided next to the metal layer.  Alternatively, heat-resistant fibrous sheets, e.g. of glass cloth or asbestos cloth, impregnated with fluorocarbon material may be used.  The sprayed metal layer may be impregnated with a P.T.F.E. emulsion before the fluorocarbon material is moulded on to it.  The initial moulding pressure should be higher than is usual with P.T.F.E., e.g. 5,000 lb./in.2, but a lower pressure of e.g. 1,000 lb./in2. may be maintained during the sintering. Alternatively the sintering may be carried out by heating without pressure, and the mould then returned to the press for cooling under a pressure of e.g. 1,000 lb./in.2.  The product may be a sheet material coated with metal on one or both sides or a shaped article.

Abstract: 1,041,634. Rolling. MORGARDSHAMMARS MEK VERKSTADS A.B. May 2, 1963 [May 2, 1962], No. 17339/63. Heading B3M. A roll pair unit suitable for use in a continuous rolling mill is angularly adjustable in the plane of the roll axes. Rolls 1 and 2 are housed in a frame 6 which is pivotally supported to a rigid framework 22 for rotation by means of a lifting eye 7a about the pass line A of the rolls. The rolls are driven by a motor 8, are axially adjustable by a screw 16, and are adjustable to vary the roll pass by set screw gearing 4. Axial and lateral movements of the rolls are restrained by abutments on the frame. A threaded bearing surface 55a (Fig. 9, not shown) allows rotation of the frame in a fixed support 22. A roller entry guide 18 is provided for the rolls. In a further embodiment (Fig. 13, not shown) the rolls and driving motor are mounted on a base 50, the base being rotatable about a pivot B and movable longitudinally relative to the pivot by means of a motor driven screw 51, thus permitting the pass line C to remain unchanged. Two frames 6 may be attached together by means of a rope passing over a pulley wheel such that rotation of one frame causes equal and opposite rotation of the other frame about the same axis.

IPC: F41A19/03
Abstract: 173,547. McCrudden, J. C. R. July 6, 1920. Machine guns. - Relates to guns of the shortrecoil type having a bolt 41 slidable in a barrelextension 30 and a boltlatch 36 pivoted at 35 to the barrel extension and formed with L-shaped slots 46, in which a pin 44 on the bolt is slidable, the pin abutting against the shorter bays 47 of the slots when the latch is dropped in the firing position, and the latch being lifted during recoil by an incline 58 to allow the bolt to be further recoiled by back pressure of the gun gases to open the breech for loading. According to the invention, the pin 44 engages with a cam-surface 46<1> formed on the forward end of each slot to force the latch downwards into locking position. An adjustable spring 51 bears on the latch and also serves to return the barrel, the breech-bolt being returned by an adjustable tension spring 55 which engages in a readily disconnectible manner with a projection 53 on the bolt. The incline 58 is adjustable longitudinally, to vary the speed of firing by turning a nut 61. The pin 44 extends to the outside of the gun to serve as a cocking- handle and engages the breech-bolt by means of a bayonet-joint so that it can be readily removed to render the gun unworkable. The rear of the gun may be opened by raising a pivoted fastening device 96 and sliding the butt-tang 60 rearwards. By then disconnecting the spring 55 from the breech-bolt and removing the master pin 44, the barrel, together with the parts carried by the barrel-extension, can be withdrawn en bloc through the rear of the casing.

Abstract: 313,097. Soc. GÚnÚrale d' Evaporation ProcÚdÚs Prache et Bouillon. June 6, 1928, [Convention date]. Density separators, discharging.-In a centrifugal machine for separating liquids from solids, means are pruvided for continuous mechanical cleaning of the discharge outlets for solids. The bowl 7 of the separator is carried by the vertical shaft 2, and has the form of a truncated cone with a number of pyramidal spaces 17 the apices of which are arranged on the maximum diameter of the bowl. Each apex is provided with a screwed plug 50 with an opening 56 communicating with a smaller opening 55 in a renewable plate 51. The openings 55, 56 form the discharge openings for the solids which collect in the spaces 17. The liquid is supplied through the tube 12 and passes through the openings 13 to the spaces between the liner plates 10. In each space 17 a rod 34 runs through a tube 35 and is connected by toothed gearing to the main shaft 2. The outer end of each rod 34 encloses a sliding rod 47 carrying at its end a block 48 which works over the surface of the plate 51. The block is centred by means of a pin 54 on the plate 51. The rotation of the blocks 48 by the rods 47, 34 keeps the discharge outlets clean, and the solids are discharged through the collectors 57 to the trough 58.

Abstract: 947,572. Selective punching apparatus. FISCHER & PORTER CO. Sept. 9, 1959 [Sept. 11, 1958], No. 17447/63. Divided out of 947,571. Heading B4B. [Also in Divisions F2 and G1] Data-recording apparatus comprises a code disc 64 with a plurality of concentric annular code-channels on a face thereof (four channels for each decimal position) and a series of codepositions extending across the code-channels the code-channels and code-positions comprising a set of high areas 221 and a set of recesses 222, the high areas and recesses of each code-position being disposed in a radial line, and a ratchetflange 65 with a tooth for each code-position. A pair of pawls reciprocated in accordance with a variable to be recorded alternately advance the disc by a tooth and the quantity registered in code at the end of regular intervals of time is recorded on a tape advanced step by step during each interval. At the end of each interval the advancement of the disc 64 is momentarily suspended while those punches in a row 232 which are backed by high areas in the codeposition aligned therewith are caused to punch the tape, the thrust being taken by a back-up rib 300. The pawls are then held clear of the ratchet-flange 65 and the disc 64 is returned to zero under the action of a spring 332. As the disc 64 rotates, gear flange 422 drives a pinion 441 on a governor shaft 440 which in this direction of rotation drives a hub 443 through a oneway spring clutch. Weighted arms 449, 450 hinged on the hub tend to apply a disc brake but are prevented by a cam follower 430 engaging a cam flange 421 on the disc 64. As zero is approached a gap 432 in the cam 421 allows the brake to be applied and the consequential reduction in governor speed reduces the braking force. If each code-position occupies an angle of 40 minutes, 503 will occupy less than 360 degrees. An " off " tooth 495 is radially aligned with a high area across the entire zone 220 so that the " off " position is recoded by a row of holes across the tape. A following toothless surface 496 prevents any further advance of the disc 64 by the pawls. If turned further manually a tooth 497 can engage a pawl and a slot 498 across the zone 220 enables the punches to be registered with the pawls upon adjustment of the punch arm 151. The apparatus may record-electricity, gas, or water consumption, or the number of vehicles passing a given point in intervals of a day or longer. A demand or code-position scale 418 on the disc 64 indicates against a fixed pointer and a maximum demand pointer 388 friotionally mounted on bearing 109 is advanced through a projection 414 on the disc 64 to indicate against a fixed scale on the plate 38.

Filed: 1943-10-25
Abstract: 567,826. Kinematograph apparatus. POOLE, R. B. Oct. 25, 1943, No. 17498. [Class 97 (i)] Apparatus for use with a kinematograph projector or camera to project or produce stereoscopic or other films having two or four images in the normal frame space, comprises, in the case of two images, a central reflector 1 and two outer reflectors 2, 3 symmetrically positioned in relation to it, all being rotatable in the same direction in synchronism with the film-feeding mechanism about parallel axes to which they are inclined at the same angles of approximately 45 degrees. During the time of each rotation, which is the normal projection period of a frame plus that taken for feeding the film, the image beam is reflected by the rotating reflector 1 successively for short periods to the rotating reflectors 2, 3 and from them, as stationary beams, to corresponding pairs of adjustable stationary reflectors 1a, 2a and 1a, 3a respectively, from which the images are projected on the screen in superposed or side-by-side relation. A mask in each light path allows only the corresponding one of the pair of images in each frame to be projected from each side. In the construction shown, the reflectors 1, 2, 3 are mounted in cylindrical cages, Fig. 7, open at the sides and at one end for the passage of the light beam to and from the reflector. The central cage is carried by a driving shaft DS and a hollow trunnion 16, through which the projection beam passes to the reflector 1, and the outer cages are carried by spindles S. The cages are geared together for equal unidirectional rotation by idler gears F engaging gear rings on the inner end members of the cages. To position the images on the screen, the reflectors 1a are adjusted about pivots 18 by the axial adjustment of collars 11, 18a, to which are pivoted stay rods 10 connected also to the reflectors. The reflectors 2a, 3a may also be adjusted about horizontal axes by an axially adjustable collar 11 connected to them by stay rods 10. When the film contains four images in a normal frame, the apparatus comprises a second system of outer rotating reflectors 2, 3 and stationary reflectors 1a, 2a, 3a at right angles to the first, so that four images are projected at each rotation. For photographic purposes a removable panel carrying an objective is inserted in each light path between the central and the outer rotating reflectors, so that successive images in a frame are taken from successive spaced points determined by the positions of the fixed reflectors.

Providing the pulse induced in the coil 11 by the sudden change in the current is of sufficient duration, both transistors are rendered conducting and the reed relay 23 closes its contacts 23a to render the feed-back circuit effective to apply a holding pulse which keeps the transistors conductive for a predetermined time even though the initial pulse has ended. The relay 23 also closes its contacts 23b, 23c to effect the interruption of the external current.

Abstract: 703,192. Pulse modulation circuits; valve circuits. GENERAL ELECTRIC CO., Ltd., and KIRKNESS, R. H. July 24, 1952 [July 24, 1951], No. 17565/51. Classes 40 (5) and 40 (6) A circuit for generating two signals having the same frequency and a pre-determined phase relationship comprises two ring counter circuits which are triggered by two signals derived from a further ring counter which is triggered by a train of regularly recurring pulses. Fig. 1 shows a circuit for generating two pulse trains, Figs. 2 (e) and (f) at the output terminals 17 and 18 respectively of two trigger circuits 3 and 4. Multivibrator 1 generates a pulse train, Fig. 2 (a) of fundamental frequency four times that of the required output pulse train which is differentiated by network 8, 9 and the negative going pulses 11, Fig. 2(b) are applied via diodes 12, 13 to trigger the trigger-pair circuit 2 to generate pulse trains at points C and D as shown in Figs. 2(c) and (d) respectively. These pulse trains are differentiated and applied via diodes to trigger circuits 3 and 4 respectively so that pulses as shown at Figs. 2(e) and (f) are produced at terminals 17 and 18 respectively. To ensure that these pulse trains have always the same relative phase relationship with each other the pulse train of Fig. 2(e) produced at point E of counter 3 is differentiated by network 21, 22 and applied to counter 4 via diode 24. The pulse trains of Figs. 2(c) and (f) may be passed through low-pass filters to produce sinusoidal waveforms having a quadrature phase relationship. Any other required phase relationship may be obtained by the use of scale-of-three, four &c. counters in place of the scale-of-two described. The circuit may be used to produce two multiplexed trains of amplitude modulated pulses or sine waves by applying the pulse trains generated at the anodes of valves 26, 30 to the supressor grids of a pair of pentode valves having a common anode load so that each valve is cut-off at its suppressor grid for one half of each cycle. The control grid biasing circuit is such that as the bias on one valve decreases that on the other increases correspondingly so that if the modulating signal is applied to the biasing circuit, a square wave voltage is produced across the common load of amplitude proportional to the modulating signal level. This amplitude modulated pulse train may be passed through a low-pass filter to give a sinusoidal waveform, or two amplitude modulated signals one each from counters 3 and 4 may be combined and then filtered to produce a single multiplexed signal having two components in quadrature and carrying different modulations.
