Abstract: 416,063. Weighing-apparatus fitted to vehicles. CORPER, L., 3, Oakville Mansions, Grosvenor Square, and KNOP, R. A. C., 40, Oxford Street, both in Southampton. March 10, 1933, No. 34403/32. [Class 143.] In a motor lorry or other vehicle the loadcarrying portion or body is connected to the frame or chassis through a plurality of hydraulic plungers and means are provided for pumping fluid through a distributing valve to lift the plungers until the load on the body is entirely supported by the fluid, the distributing valve being so constructed that each plunger may be selectively connected to a pressure gauge so that the load on each plunger may be independently determined, and thereby the load carried by the vehicle may be calculated. By operating the handle L of the pump K oil is drawn from a tank J and passed through a three-way cock H and a five-way distributing valve F to the four plungers B until the limit of lift of the plungers is reached. The plungers are then successively connected by means of the distributing valve to a gauge o and the various readings are added together to give the load on the lorry. If the load is symmetrically distributed in the lorry, the distributing valve may be left in the position connecting all the plungers, the load then being given by four times the gauge reading. The oil may be returned to the tank through the three-way cock H allowing the plungers to descend to their inoperative positions.

Patent GB-343157-A (GB)
Title: A single acting fluid pressure engine
IPC: F03C1/013
Filed: 1929-11-15
Abstract: 343,157. Fluid - pressure engines. PREPARATION INDUSTRIELLE DES COMBUSTIBLES SOC. ANON., 23, Boulevard de Strasbourg, Nogent-sur-Marne, Seine, France. Nov. 15, 1929, No. 34976. Convention date, Nov. 15, 1928. [Classes 122 (ii) and 122 (iii).] A single-acting fluid-pressure engine has series of exhaust ports on lines transverse to the cylinder axis which may be closed at will, and the distribution is controlled by differential fluid-actuated supply and auxiliary exhaust valves and the main piston. In the engine for conveying troughs in mining works shown, the admission valve moves in a chest 3 and has differential actuating-areas 4 .. 7. The upper and lower areas of the valve form cushioning areas. The cylinder has ports 12, 13, 14 connected to a duct 15 leading to the face 7. The ports are controlled by heads 12a, 13a, 14a on a valve 16 subject to the supply pressure at one end and to a spring and the cylinder pressure at the other end. When the supply pressure is a maximum and the load normal, port 13 is open. When the pressure is a minimum and the load a maximum, ports 12, 13 are closed and port 14 is opened. When the load diminishes and the piston overruns, the valve 16 moves to the left and effects the cut-off. The auxiliary exhaust valve 23 works in a vertical chest with cushioning holes 41, 42. When the port 29 is closed by the piston moving to the left, the compression raises the valve to close the exhaust port 26. The series of exhaust ports 30, 31, 32 which determine the piston stroke are controlled by collars 33 on leather straps operated by screw- and-nut mechanism, Fig. 2. Additional holes 36 open to the atmosphere are provided at the cylinder end. During working, after the main exhaust is opened, the weight of the trough returns the piston and closes port 29. The compression closes valve 23 and acts upon the admission valve face 6 and lowers the valve until the channel 2 is uncovered when the valve movement is completed under supply pressure. The piston is moved to the right and the valve 16 is moved to a position of balance. When the port 12, 13, or 14 communicating with the channel 15 is opened, pressure fluid passes to the surface 7 and effects the cut-off. The piston continues its movement until the main exhaust is opened after which the valve 23 opens and the piston moves to the left. The admission adjustment may be non-automatic, the valve 16 being replaced by needle valves controlling the ports 12, 13, 14. Specification 340,926 is referred to.

Title: Voice frequency signalling system for telephone systems
Inventor: VRIES WILLEM CECIL DE
IPC: H04B3/20
Filed: 1947-12-31
Abstract: 648,849. Exchange systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 31, 1947, No. 34977. Convention date, Oct. 2, 1946. [Class 40 (iv)] In a telephone system employing voice frequency signalling, false operation of signal receivers by the presence of signal frequencies in speech is prevented by direction-sensitive signal suppressors located at the extremities of the system and consisting of valve-controlled variable attenuation networks which attenuate the speech before the signal receivers have time to respond. As shown in Fig. 2, voice frequency signals are transmitted over a 4-wire system from contacts 1 and 3 to signal receivers 2 and 4 respectively. Signal suppressors 5 and 6 provided in the two-wire terminating circuits respond to signalling frequencies originating from ends A and B respectively and insert sufficient attenuation to prevent operation of the signal receivers. In an alternative arrangement, Fig. 1 (not shown), the system is twowire throughout. In a modification of Fig. 2, Fig. 3 (not shown), the signal suppressors may be fitted in the out going circuits of the 4-wire system as in Fig. 4. A delay circuit 7, which has a propagation time at least equal to the response time of the signal suppressor, may be connected in the speech circuit between the valve portion 5a of the suppressor and the variable 'attenuation network 5b so that the whole period in which the speech contains signal frequencies is controlled. Series and shunt connected band-filters (Fig. 5, not shown) may be used in association with the suppressor so that only a narrow speech band which contains the signal frequencies is attenuated. The signal suppressors and signal receivers may alternatively be fitted with blocking circuits which distinguish between a voice frequency signal and the signal frequency present in speech. The signal suppressors also provide protection for the system against interference from tandem-connected systems using the same signalling frequencies, as described in Specification 646,848, [Group XIV].

Title: Bulked continuous filament yarns
Inventor: BLOCH GODFREY
IPC: D02G1/18
Filed: 1962-09-14
Abstract: Bulked synthetic filament yarn is produced by individually spinning e.g. at different speeds, separate bundles of filaments of similar or different materials (polyacrylic, polypropylene, polyethylene) and/or denier; passing the bundles through a coagulating bath wherein the stretch characteristics of each bundle is individually controlled e.g. by shrinking one bundle and not the other; individually stretching each bundle and, optionally, relaxing one bundle by heat treatment; separating the filaments by use of an air jet or guider and then combining the bundles so that the filaments are intermingled and/or with the filaments of one bundle distributed predominantly on the outside of the filaments of the other bundle; subjecting the filament assembly to a shrinking treatment e.g. by heating in a dryer or oven (before or after spinning into yarn or before or after knitting, weaving or tufting the yarn into fabric) so that filaments having a high shrinkability cause bulging and crimping of the other filaments.  The filaments may be bonded at spaced intervals or at points of cross-over by heating (e.g. in the final shrinkage treatment) or adhesives.
