Title: Improvements in and relating to laminated materials and articles
IPC: B32B15/08
Filed: 1935-06-14
Abstract: 442,066. Compound sheet materials. CELLULOID CORPORATION, 290, Ferry Street, Newark, New Jersey, U.S.A. June 14, 1935, No. 17162. Convention date, June 26, 1934. [Class 140] Compound sheet materials are made by interposing metal elements between two sheets of plastic composition at least one of which is transparent or translucent and directly uniting the sheet through the interstices between the metal elements so that at least part thereof is embedded to continuously variable depths in one or both of the sheets. The metal elements comprise metal threads, strips of metal foil, e.g. in the form of tinsel or woven or knitted into fabric, and may be associated with fibres such as wool or cotton, e.g. as lahm cloth. The plastic sheets may comprise cellulose esters or ethers and plasticizers. The base sheet may be transparent, translucent or opaque and may be coloured, mottled, variegated or pearl-like in appearance. It may be laminated and may contain powdered bronze or aluminium. The transparent sheet may be laminated, coloured or decorated. Union of the plastic sheets is effected by moistening with a medium boiling solvent, e.g. butyl acetate, to which low or high boiling solvents may be added, and applying heat and pressure. The products may be formed into tubes for fountain-pen barrels or applied to a base material such as wood or metal to constitute table tops.

Title: Improvements in fluid turbine
IPC: F01D5/04
Filed: 1946-06-06
Abstract: 612,922. Elastic-fluid turbines. DARLING, L. A. June 6, 1946, No. 17232. [Class 110 (iii)] Turbine blades providing for peripheral admission with divided flow and lateral discharge on both sides are formed of complementary parts fashioned from sheet metal blanks, Figs. 5 and 6, into the forms shown in Figs. 10 and 11. In Fig. 10, two such parts are shown in position. When the further part on the left of the Figure is placed so that its side plates 51 overlie the side plates 67, a complete passageway is formed. Fig. 11 shows the assembly. Working fluid directed tangentially is divided by the ridge piece 69, impacts on the curved surface 54 and is discharged through lateral passages 75. The spaces 84 communicate with the spaces within the oblique walls 70 and cooling fluid from within the rotor may circulate in them and be discharged in the same direction as the working fluid through passages formed, between the parts 65, 52, by pressing outwards the centre of the parts 52. Blades for lateral admission and peripheral discharge may be formed similarly. In bladings of large size, the passages for the working fluid may be subdivided by curved plates parallel with the surfaces 54. The blade elements may be secured to the rotor as shown in Fig. 4. The 'side plates 51, 67 are bent around the flanges of the rotor discs 26, 27 and into the annular troughs within the flanges. They are secured there by retaining rings 82. In the turbine shown in Fig. 2, a rotor formed of dished side plates 26, 27 carries a set of blades receiving working fluid from central tangential nozzles 17 and discharging laterally. In the form shown on the left of Fig. 2, a second ring of simple blades 34 is provided on the rotor which for this purpose also includes side discs 30 and the working fluid then passes through nozzle guides 40 to a final rotor 22. In the form shown on the right of Fig. 2, the second ring of blades 33 have a lateral admission on one side and discharge peripherally. The discharge then passes inwards to the nozzle guides 41 and on to the blades 37. When a cooling fluid is used, the blade parts may be formed with inwardly projecting scoops to force the fluid into the cavities within the walls 70, or the rotor may have fan-like blades between its side walls. When water is used, it is evaporated within the rotor and is discharged as steam through the blades.

Title: Method of ripple-control through a power-supply system and an arrangement for carrying out this method
IPC: H02J13/00
Filed: 1974-04-19
Abstract: 1468035 Ripple-control systems ZELLWEGER USTER Ltd 19 April 1974 [18 May 1973] 17259/74 Heading G4H [Also in Division H4] Ripple control signals in angle-modulated form are sent between a transmitter and a receiver whose transmission and reception response frequencies respectively are locked in a fixed relationship relative to the power frequency. Control signals of this kind need only be at a level in the region of 0À1% of the mains voltage and their effect in neighbouring substation networks is negligible. Although phase or frequency modulation is possible, the preferred embodiment uses FSK signals. A 4-bit signal is set up by switches 2-5, Fig. 2, and fed by a coder 1 after a start pulse St to a modulator to where the bits are keyed to 124À333 Hz for a "0" and 125À667 Hz for a "1" for transmission by, e.g. a static inverter 14 to a coupling circuit 18 in the substation feed k. The frequencies are chosen to lie between harmonics of the mains and are derived (as are all clock &c. frequencies) from the mains frequency f N  at 23. The transmitter, Fig. 6, includes a section 10A which receives mains frequency f N  at input 12, forms a shaped pulse sequence at 210 and produces a reference frequency f R1  at output 201 by means of a phase-locked loop controlling a Wien bridge oscillator 214 running at a nominal 500 kHz. The frequency f R1  is used in another phaselocked loop 236 whose oscillator 237 is caused to run at 7À46 or 7À54 MHz and a divider 235 to divide by 1492 or 1508 depending on the binary data at terminal 9. The oscillator output is  divided by 100 then 600 in dividers 241, 245 to produce the signal frequencies f 1 =124À333 Hz and f 2 =125À666 Hz at terminal 11. These frequencies are coupled to the substation feed by a shortcircuit proof, bar-type current transformer (Fig. 13, not shown) incorporating a mains frequency trap and an L-C circuit resonant at the audiofrequency of the control signals. The receiver, Fig. 14, includes an active RC filter in cascade with an N-path filter 604 to extract the frequencies f 1 , f 2 , a two stage OP- amp. limiter 608 and a discriminator 612 incorporating a further N-path filter, buffer, rectifier and threshold detector to recognize the frequencies f 1 , f 2  for passage to a shift register 616 having 4 flip-flops and corresponding stores to energize transistor switches and operate corresponding control relays. All operations are synchronized 618, 624, 629 with f N . Circuit stocks such as the transmitter clock and the components of the phase-locked loops are outlined.

Title: Improvements in machines for making a plurality of imprints on a strip or tape
IPC: B41K3/04
Filed: 1949-07-01
Abstract: 660,332. Feeding webs; printing-machines. MARKEM MACHINE CO. July 1, 1949, No. 17430/49. Classes 100 (i) and 100 (ii). [Also in Group VIII] A strip-marking machine has a rectilinearly reciprocating printing head actuated through a lever by a driving shaft carrying a cam for rocking the support of a freely rotatable impression cylinder over which the strip passes, the rocking action making the cylinder tangential to the plane of movement of the type face on the printing head during advance of the printing head, and lowering the cylinder into an inoperative position during return of the printing head. As shown paper 4 from a supply 34 resting on rolls 36 in a drum 35 is led through laterally adjustable guides 41 to a rubber &c. covered impression cylinder 3 mounted on a support 21 which is rocked about its fixed pivot 72 by a cam 22 on a driving shaft 18; a crank pin 16 thereon carries a block 15 which slides in a channel 14 formed between side flanges on a lever 9 forked at 11 to engage a fixed pin 12 and pivoted at 10 to a carrier 5 slidable along a rod 6 and having a printing head 1 and an ink pad holder 31 mounted thereon. A roll on a fixed pin 33 transfers ink from the pad to the type elements 2; a shoe 26 on the printing head, having a lower rubber face exchangeable for length variation, drives the impression cylinder 3 during the printing stroke, and a brake 29 holds it stationary during the return stroke. An extension 56 of the rocking support 21 operates a perforating device 44 (see Group VIII).

Abstract: 859,310. Track apparatus. WERK FUR SIGNAL - UND SICHERUNGSTECHNIK BERLIN VEB. June 3, 1957, No. 17568/57. Class 105. In a railway level-crossing arrangement the start of the warning signal at the crossing is delayed, after entry of the train into the level-crossing approach section, to give a warning of predetermined fixed duration whatever the train speed may be, this being effected by a circuit arrangement comprising a capacityresistance control C 2  - R of an electronic tube with an associated anode relay B and bias potentials + Ue, - Ue and a slow release relay A all controlled by train-operated contacts K 1  . . . K 5  operating in the manner hereafter described. Entry of a train into a short preliminary section, defined between trainactuated contacts K 1 , K 2'  first actuates contact K 1  whereby a slow-release relay A is deenergized and after a time to drops its contact a, to apply a potential +Ue instead of a potential - Ue to a resistance-capacity R - C 2  connected with the grid and anode of an electronic tube having in the anode circuit a normally de-energized relay B the relay thus becoming energized, but the voltage at the anode falling for a time t 1  linearly with time. Shortly after this action has been initiated the train actuates the contact K 2  to re-energize the relay A the contact a of which thereupon re-applies the potential - Ue to the resistance-capacity R - C 2  and electronic tube and anode relay B the voltage at the anode thereupon rising linearly with time but at a slower rate so that the anode relay does not become currentless until a time t 2  whereupon back contact b closes and as contact K 2  is already closed the warning signal at the level crossing comes into operation. The values of + Ue and - Ue (and if desired alternative resistance-capacities R - C<SP>2</SP>) are selected so that t 2 /t 1  = L/l where l is the length of the short preliminary section K 1 -K 2  and L the length of the level-crossing approach section K 2 -K 3 . The warning signal is in operation for a fixed time Lt 0 /l for all train speeds providing the train is not so slow as to have allowed the voltage at the anode to have reached its basic minimum before the contact K 2  is actuated. In a modification (Fig. 4, not shown), a normally de-energized relay acts as a signal initiating means, i.e. without any time lag.

A tapped delay line, for use in a transversal equalizer, comprises, for each delay stage, pairs of storage elements, e.g. capacitors 20 and 20<SP>11</SP>, with isolating circuits between the pairs of stores and between one storage element of one stage and the other storage element of an adjacent stage, with the isolating circuits being rendered conductive alternately to transfer an analogue value along the delay line. As shown in Fig. 2, square waves of opposite polarity PC1 and PC2 are applied to render diodes 21 and 22 conductive while diodes 21<SP>11</SP> and 22<SP>1</SP> &c. in the adjacent stages are non condutive and vice versa. While a positive PC1 pulse renders diode 21 non- conductive a short positive PR1 pulse charges capacitor 20 to its most positive potential then, when the PR1 pulse finishes capacitor 20 discharges to the value held in the previous circuit. When the PC1 signal goes negative diodes 21 and 22 are rendered conductive and the signal is fed, via the voltage follower circuit 23, 24, to the capacitor 20<SP>11</SP> of the adjoining stage, after the capacitor has been charged to its most positive potential by a short positive PR2 pulse. In an alternative arrangement the diode gates are replaced by a field effect transsistor (41) Fig. 4 (not shown) connected between the output of the voltage follower circuit and the succeeding capacitor. In this arrangement only opposite phase square waves are required, applied to the fet gates.

Abstract: 1,126,426. Socks. ALAMANCE INDUSTRIES Inc. 18 April, 1967 [18 April, 1966], No. 17831/67. Heading A3V. [Also in Division D1] A sock has the major portion of the leg knitted as a mock rib from two yarns in an alternating sequence one yarn being a stretch or inelastic yarn which is knitted in every wale in alternate courses and the other yarn being an elastic, e.g. spandex, yarn which is knitted in alternate wales and floated in the intervening wales on the intervening courses. In the calf portion of the sock, however, both yarns are knitted in every wale in an alternating course sequence so that the calf portion stretches more readily to a greater extent than the rest of the leg but, since there is a greater length of elastic yarn in the calf portion than in the rest of the leg the greater compressive force on the calf is about the same as that exerted on the rest of the leg. The top of the stocking may be a woven elastic band secured to the top of the leg or a normal knitted top.
