Title: Improvements in or relating to thermoplastic material for cutting into interlayer inserts
IPC: B41F19/00
Filed: 1955-11-22
Abstract: 819,263. Coating thermoplastic materials; laminated safety glass. PITTSBURGH PLATE GLASS CO. Nov. 22, 1955 [Feb. 4, 1955], No. 33389/55. Class 140. [Also in Group XVI] A non-rectilinear or scalloped coloured longitudinal band is coated on a thermoplastic web and the web cut into portions for use as an interlayer for a curved laminated glass assembly by means of a printing assembly including a rotating printing roll for printing the band in a repeating pattern on the web, a conveyer for feeding the web through the printing assembly, and cutting means for cutting the web into portions. As shown, a web W of thermoplastic material, e.g. polyvinyl butyral resin, is fed by conveyers 12 and 13 beneath an intaglio printing roller 15. The roller 15 has concavities which are graduated in size and depth from one end to the other to provide a greater intensity of colour at one edge of the band than the other. The dye is applied to the roller 15 by a roller 56 dipping into a duct 57. The dye which is light-absorbing may be a solution of anthraquinone-type of green dye used in the amount of 0.25 gram per 100 ml. of solvent, in addition the solution preferably contains polyvinyl butyral and triethylene glycol di-2-ethylbutrate. Using this dye, the roller 15 has cavities at least 1.2 x 10<SP>-2</SP> mm. deep. After printing, the web W is dried in a housing 75 maintained at a temperature of about 50‹ C. and is then drawn between rollers 14 to a dancer roll 81 and through rollers 94 to a die press to cut the web into lengths. The dancer roll 81 forms a loop in the web while the rollers 94 are stopped during cutting.

Abstract: 325,274. Burovox, Ltd., and Smith, S. C. Winfield-. Nov. 15, 1928. Direct call systems. - In a system in which a principal may call a subordinate or other party, receive the answering call on a loud speaker, and speak from a distance into a sensitive microphone, a visible or audible signal is operated by current fed to the principal's microphone when the called party is in a position to listen. Thus the principal is warned when conversation in his room may be overheard and he may be provided with a switch to open his microphone circuit. In the arrangement shown in Fig. 1, the loud speaker a and microphone b at the principals station A are respectively connected in series with the transmitter e and receiver f at the subordinate's station B. The operation of key c completes the circuit of a buzzer or other calling device h at B, and when the called party replies by lifting his receiver off the hook i, speaking circuits are completed, and signal device d, which may be directly or indirectly operated by microphone current, warns the principal who may break his microphone circuit by restoring c. The party at station B may call A by removing his receiver and speaking into his transmitter. In the modified arrangement shown in Fig. 2, three. stations A1, A2, A3 similar to A, Fig. 1, but provided with separate calling and overhearing- preventing keys o, p, and installed for example in ships' cabins, may communicate with a station B1, in the steward's cabin for example. Station B1 is equipped with a buzzer &c. h, indicators u and a two-wiper switch s, t, constructed as described in Specifcation 319,861, by which the party at B1 completes the speaking circuits. The Provisional Specification also describes the signal device as being in the principal's receiver circuit.

Abstract: 1,063,547. Correlation detectors. MOTOROLA, Inc. Aug. 5, 1965 [Aug. 19, 1964], No. 33577/65. Heading G1U. To distinguish between identical signals transmitted over different paths, e.g. # 1 , # 2 , # N , in a signal transmission system which includes a transmitter 45 providing a modulated carrier wave signal and a receiver 51, the carrier is modulated at the transmitter from a generator 43 supplying a first quasi-random noise signal, consisting of pulses in a predetermined order having a predetermined period and a first duration. The receiver includes a signal generator 58 for developing a reference signal which is modulated at 57 by pulses, from a second quasi random noise signal generator 55, having the same predetermined order and period and having a second duration no greater than the first and less than the interval between the reception of any two identical signals. The second quasi-random signal may in fact be substantially the same as the first. In the receiver the received carrier wave signal and the modulated reference signal are correlated by means of a multiplier 49 and integrator 50. A correlation function which distinguishes between identical signals transmitted over different paths is developed. The receiver includes phase shifting arrangements 54, 56 for adjusting the phase of the second quasi random noise signal in order to bring it into phase with a particular received carrier wave.

Title: Improvements in or relating to a speed controlling device for pattern withdrawing orseparating apparatus of moulding machines
IPC: B22C19/04
Filed: 1954-11-29
Abstract: 759,239. Moulding-machines. AKTIEBOLAGET WESTIN & BACKLUND. Nov. 29, 1954 [Dec. 2, 1953], No. 34527/54. Class 83 (1). In a moulding-machine in which the pattern withdrawal is effected by a fluid-pressure. actuated piston, and a control-device actuated by said fluid-pressure controls the patternwithdrawal so that it occurs at a lower'speed in a first stage of the operation than in the remaining stage, the control-device comprises a valve which opens an outlet for the fluid within the operating cylinder, said valve being subjected to the pressure prevailing within said cylinder and to the oppositely-acting pressure within a compression-chamber in which the pressure is dependent on the downward movement of the operating - piston. The control - device comprises a casing 9 having a valve-chamber 12 containing a valve-piston 11 with a central bore 14 communicating with cross-passages 15 which, in a predetermined position of the piston, Fig. 1, register with exhaust passages in the casing 9, to allow fluid to be exhausted from below the piston 11. In its upper position the piston 11 contains a spring-loaded non-return valve 18, which, under pressure from below, will allow pressure-air to pass from the chamber 12 to a cylinder 23 containing a piston 22 whose rod 24 co-operates with the pattern-plate 1. During ramming, Fig. 2, air is supplied beneath the operating-piston 4 through a pipe 5 and also into the chamber 12 through a pipe 8, raising the piston 11 to cover the exhaust-port 16 and, through the bore 14 and valve 18, to cause the piston-rod 24 to follow the pattern-plate. A governor 6 in the pipe 5 allows free flow to the cylinder 3 and a controllable through-flow in the opposite direction to control the initial withdrawal speed. When pattern withdrawal is to take place, air is admitted above the piston 3 through the pipe 7 and the air below the piston 4 is exhausted through the governor 6. In its downward course the pattern-plate 1 urges the piston 24 downwardly and, the valve 18 being closed, pressure builds up in the cylinder..23. After a predetermined period the piston 11 will move downwards and compressed-air in the cylinder 23 escapes slowly through a calibrated vent 25. At the same time, passages 15, 16 are aligned and constitute an exhaust for the air in the pipe 5 so that the piston 4 and patternplate 1 descend at a faster speed. The interval of time which elapses before the piston 11 moves from its upper to its lower position, when withdrawal commences, is determined by dimensioning of its upper and lower areas.

Abstract: 1,152,728. Centrifugal pumps. SIEMAN & HINSCH m.b.H. Aug. 2, 1966 [Aug. 3, 1965], No.34601/66. Heading F1G. In a self-priming centrifugal pump with at least one full-admission stage and a priming stage lying outside the main impelling flow, the suction of air or gas from the pump is effected in the first half (viewed from the volute tongue in the direction of rotation) of the volute casing of a full-admission impeller. The pump shown comprises a fulladmission main stage having an impeller 1, primed by a partial-admission priming stage of the sidechannel or liquid-ring type having an impeller 2. Air or gas is withdrawn from the main stage via a bore 9 or 10 opening into the first half (viewed from the volute tongue in the direction of rotation) of the volute and leading (via external passages if necessary in the case of the bore 10) to the suction chamber 12 of the priming stage. Preferably, the priming stage discharges into the pump discharge pipe, i.e. beyond the flange 5 (and beyond the non-return valve, if provided). The tongue (11, Fig. 2 not shown) of the volute is extended downwardly so that the impeller 1 discharges into the lower part of the volute. The liquid seal then forming in the upper, downstream part of the volute and extending beyond the flange 5 and into the discharge pipe does not reach the points at which the bores 9 and 10 are located and therefore does not hinder the withdrawal of air or gas.
