Title: Improvements in typographical composing machines
IPC: B41B11/06
Filed: 1940-11-01
Abstract: 539,919. Type-bar-making machines. INTERTYPE, Ltd. Nov. 1, 1940, No. 15990. Convention date, Dec. 30, 1039. [Class 100 iii)] Assembling and distributing matrices. In machines adapted for handling 72 and 90 character founts, and having two distributers, two fixed assembler entrances, and a single set of key-operated rods adjustable by means of a hand-lever for releasing matrices from either magazine of a pair, a single adjustable distributer box, adapted to direct matrices to the proper distributer, is also operated by the hand-lever. The esoapements are operated by two sets of rods 16, 17, Fig. 1, adapted for 90 and 72 character founts respectively, and either set is actuated by a single set of key-operated rods 27 mounted in a swinging frame 28, which is adjusted by means of a hand-lever 30. The hand-lever also acts through a link 60 and a lever 64 to adjust a pivoted distributer box 52, shown in plan in Fig. 6 into engagement 'with one or the other of two distributers 22, 23. The distributer-box is carried by an arm 53 movable about a pivot 54 and is locked in either position by a lever 83, which engages in notches 84, 85. The lever 83 is itself locked by a pawl 90, which is withdrawn by one or the other of two pins 94, 95 on the distributer shifter-slide, 58 that transfers the matrix line to the distributer. A change of distributer therefore cannot be made whilst there are matrices undelivered to the distributer. When the pawl 90 has been withdrawn, the locking-lever 83 can be retracted by a cam-lever 77 operated from the lever 64. A lost-motion connection allows the lever 83 to be moved before the distributer-box is shifted. Change of distributer after composition is prevented by a locking-bar, which is moved into the path of the hand-lever by the assembler-slide when the first matrix enters the assembler. Means are provided for preventing a magazine containing a 72-character fount from cooperating with the lower assembler-entrance 19, which is designed for 90-character founts. The 72-character magazines are wider at their lower ends, and rollers are provided on the machine frame between which a 90-character magazine can pass, but which support a 72-character magazine at a level at which its escapements cannot be operated. Specifications 14582/90, [Class 100]. 262,670, [Class 100 (iii)], 422,524 and 532,723 and U.S.A. Specifications 1,202,719 and 1,960,182 are referred to.

Abstract: 615,260. Hot-gas engines. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 27,1946, No. 16008. Convention date, March 18, 1942. [Class 7 (i)] The cylinder head of a hot-gas engine comprises an outer wall 14 which, when the engine is in operation, is subjected at its inner side to a pressure equal to the average cylinder pressure, and an inner wall 13 separated from the outer wall by a space 19 in which the average cylinder pressure prevails. The wall 13 is made of a material, such as aluminium bronze, which is resistant to attack by the working medium at the temperature prevailing during engine operation. The pressure is maintained in the space 19 by providing a capillary aperture 18 in the wall 13. It relieves the load on the inner wall due to pressure in the cylinder 10. Preferably, the space 19 contains slag wool to prevent circulation of working medium in it. Specification 4472/02, [Class 7], is referred to. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which gas under pressure in the space 19 is introduced from the outside through the wall 14. Also a modification is described in which a filling of ceramic material and a rib on the wall 13 transmit load from the wall 13 to the wall 14. An outer layer of asbestos wool may be provided to prevent heat losses. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,004,362. Rollers. METAL-TECH. Inc. April 24, 1963, No. 16070/63. Heading F2U. A paper-making roller comprises a hollow cylindrical openwork honeycomb formed by thin, wide, flexible longitudinal strips 31-34 of stainless steel or P.T.F.E., angularly bent into alternate flat-faced corrugations and secured together, by epoxy resin, to form radial hexagonal fluid conduits 51, some of the pairs of strips being of greater length than the intermediate pairs and having their ends secured by epoxy resin in radial slots 27 formed in a pair of end heads 21, 22, which are also shouldered at 28 to provide additional support for the intermediate pairs of strips. Additionally, axially spaced support rings 70-73 are arranged within the cylinder, the rings and strips being notched to interlock. A similar honeycomb structure may additionally be used to form an edge seal around an arcuate frame section of a cooperating suction box (Fig. 3, not shown), arranged within the roll, the honeycomb structure being arranged as a lining around the edge of the arcuate frame to which it is secured by epoxy resin forming cells which create a pressure drop across the interface and thus seal the edge. The clearance and pressure drop may be changed by threaded adjusters, at each end of the suction box, which vary the radial position of the frame relative to the inner surface of the roll. This arrangement may also serve as a dryer, e.g. when the suction is replaced by compression to blow the air outwardly through the roll.

Abstract: 367,338. Control of D.C. motors. FAY, J. M., 88, Merrion Square, DRUMM, J. J., University College, and CELIA, Ltd., 42, St. Stephen's Green, all in Dublin. Aug. 16, 1930, No. 16330. [Class 38 (iii).] Varying electromotive force.-The motor u in a battery-driven traction system is accelerated by connecting it to various tappings of a subdivided battery I .. XII. At each stage resistance is included in series and is cut-out in steps, and then the effect of the series field u<2> is weakened by increasing in stages the effect of an opposing shunt field u<1>. Thereafter the resistance is reinserted, the next higher tapping of the battery connected in such a way that one step of the resistance is between the two tappings, and then the lower tapping is disconnected and the sequence proceeds as before. The actual tapping and resistance control is performed by an electromagnetic contactor controller r under the control of a master controller s, to which is geared a controller t for the shunt field u<1>. The controller t makes one complete revolution for each stage of the controller s. Regeneration is obtained when the controller s is turned backwards by a lostmotion device causing the series field u<2> to be excluded and the shunt field to be reversed. In order to equalize the discharge of the battery sections I .. XII a controller p is automatically moved one step each time the master controller s is returned to its "off " position. The controller p effects a cyclic change of the connections of the sections I .. XII to the leads a .. m. Further, a controller q normally interconnects the leads a .. m so that the battery sections are in series with tappings taken off by the leads A .. N, but in order to equalize the charge of the sections, it can be moved so as to disconnect them from the leads A .. N and to connect them in parallel for charging. The invention is applicable to the traction system, disclosed in Specification 345,233, [Group XXXV].

Title: Improvements relating to devices for measurement of solid material in suspension ina liquid
Inventor: COOPER DAVID HENRY
IPC: G01N21/15
Filed: 1963-04-26
Abstract: 1,005,347. Photo-electric turbidometers. BRITISH TRANSPORT DOCKS BOARD. April 23, 1964 [April 26,1963], No. 16573/63. Heading G1A. [Also in Division A4] A submersible device for measuring the solid material in suspension in the liquid in which it is placed is designed to be left in position for a considerable period. A silt meter for a river or harbour is described in which light from a source in the device is directed across a gap filled with the liquid to a photo-cell so that the transmissivity of the liquid can be determined. Both source and photo-cell must be separated from the cell by windows and these tend to become coated with material deposited from the liquid. According to the invention the device is provided with a window-cleaning element which can be operated by a remote control to clean the windows whilst the device remains submerged. In Fig. 1 the windows are shown at 5 and 6, liquid being allowed to flow between them through apertures 7 and 8. The window-cleaning element consists of a plastic sponge 14 clamped between plates 16 and 17 on rod 15 mounted on a plunger 12 slidable within the body 1 of the device. The body 1 is suspended by a flexible hose 9 through which water may be pumped to cause the plunger and attached sponge to move downwards. Passage of the sponge over the windows can be detected from the photo-cell output and when the plunger reaches the lowest position apertures 27 and 28, past which the clean pumped water flows, lie opposite the source and cell windows so that a zero check can be made. A spring 20 returns the plunger to its normal position when the clean water pressure is reduced. A non-return valve 18 is provided in the bottom of the plunger and sample liquid can be drawn through this and inlet ports 22 up the hose 9. Thus calibration of the device can be done by analyzing samples so withdrawn and comparing the result with the photo-cell current at the time of withdrawal.

Abstract: 858,208. Electric analogue calculating sytems. BENDIX CORPORATION, [formerly BENDIX AVIATION CORPORATION]. May 15, 1959 [May 28, 1958], No. 16769/59. Class 37 An integrator comprises a transfluxor, means for applying to a control winding of the transfluxor a modulated pulse train constituting, or derived from, the signal to be integrated, means for applying to an excitation winding of the transfluxor an excitation voltage concurrently with the pulse train, the output signal from an output winding of the transfluxor representing the desired integral. In Fig. 1, the input pulse train is derived from an alternating input signal e.g. a postional displacement signal from an aircraft control signal by being first passed through a demodulator 1, and chopped in a chopper 3 to derive a train of d.c. pulses. Amplitude modulated in correspondence with the modulation of the a.c. input. Alternatively, the d.c. pulse train may be width or frequency modulated, or there may be modulations present in addition to represent other parameters. The d.c. pulse train forms the control signal for the transfluxor which is biased by a winding 8 to a state intermediate its "blocked" and "unblocked" state. The primary winding 13 is excited from an a.c. source 15 and the output representing the integral of the input signal is taken from the secondary winding 17, rectified in 21 and remodulated in a modulator 19 into a carrier 20, In order to compensate for the initial biassing of the transfluxor and to fix the integration constant so that the integral is zero when the integral is zero the output from modulator 19 is opposed by an a.c. voltage of opposite phase derived from a transformer energized from a source 25 of the same frequency as, but of opposite phase to, carrier source 20. The integrator device may be inserted in the direct or feedbank channels of a servo loop (Figs. 2 and 3, not shown) to give outputs having exponential transients.
