Filed: 1973-08-31
Abstract: 1448271 Vehicle bumpers SOC ANON DES USINES CHAUSSON 31 Aug 1973 [27 Oct 1972] 41205/73 Heading B7J [Also in Division F2] A vehicle shock absorber comprises a bumper 7 connected to a piston 5 which bears against a series of elements 12, 13 applied against a stop 17 provided on a longitudinal beam 1 of the vehicle so that a shock received by the bumper 7 is transmitted by the piston 5 to the elements 12, 13 which undergo permanent distortion to absorb the energy of the shock. The elements 12 and 13 are housed within the beam 1 and are held pressed together by a spring 11 acting on the piston 5, which is guided in a tube 4 mounted in the beam 1 by a resilient ring 10 of rubber. Movement of the bumper 7 in a collision is also guided by slides 9 on each lateral side of the vehicle, as well as by a guiding rod 15 extending from the piston 5 through a central hole 16 in the stop 17. As shown in Fig. 1, the elements 12 are corrugated washers while the elements 13 are flat washers but, in other forms, various plates and washers having corrugations or other protuberances may be used, Figs. 5 and 6 (not shown). In Fig. 2, the elements 12 1  and 13 1  are contained in a distortable cardboard cartridge 24 within a hollow piston 5 1 , which is guided by a rounded edge 18a 1  of a central aperture in a cover 18 1 , and abut against a body 22 carried by the stop 17 1 . Other embodiments in Figs. 3 and 4 (not shown) may receive more than one shock since they include an intermediate piston 25 which is acted upon by a spring 26, so that partial distortion of the elements 12, 13 is taken up by forward movement of the piston 25. Piston 25 cannot be forced backward, when receiving a shock, due to a pawl-and-ratchet mechanism 28, 27.

Abstract: 844,914. Travelling-wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 24, 1958 [Dec. 31, 1957], No. 41674/58. Class 39(1). A travelling-wave tube with crossed electric and magnetic fields in which the magnetic lines of force are circles about an axial conductor 1 has a number of sole electrodes 23 surrounding the axial conductor and a delay line 8 which is periodic both in the direction of the axial conductor and in the direction of the magnetic lines of force in order to suppress parasitic modes of operation. As shown there are three sole electrodes 23, 24 and 25 at increasing negative potentials. The cathode 3 is annular and the electrons are concentrated into a tubular beam by the anode 22 and the magnetic field. The axial conductor 1 is hollow for the circulation of cooling fluid and thermal expansion is allowed for by the bellows 11. The delay line is composed of alternate washers 36, Fig. 4, and 40, Fig. 6, held tightly together by means of bolts 44. Preferably the bolts 44 are composed of a material having a coefficient of expansion which is less than that of the washers so that the tightening is increased when the assembly is heated for the purpose of brazing the washers together. Coupling connections from the end washers to the inner conductors 45 of the input and output -lines 9, 10 are as shown in Fig. 8. In modifications, the axial conductor 1 may be integral with the envelope 7 and auxiliary cathode may be provided between the sole electrodes 23, 24 and 24, 25 to augment the electron flow. The cathode may be pulsed and A.C. passed through the axial conductor, the direction of current flow being in synchronism with the blocking or unblocking of the cathode. Specification 705,783 is referred to.

Abstract: 1436313 Measuring fluid pressure in body cavities NATIONAL RESEARCH DEVELOPMENT CORP 13 Sept 1973 [13 Sept 1972] 42577/72 Heading A5K [Also in Division G1] To measure pressure in a confined space a remote location e.g. the amniotic fluid pressure in the uterus, a sealed system is used comprising is tube 1 having a flexible sac 2, 3 at each end made of rubber or synthetic film material, the system being filled with a gas, e.g. air, at substantially atmospheric pressure, changes in the pressure on the sac 2 positioned in the confined space being conveyed to the sac 3 whose consequent volume changes are detected, e.g. by a transducer of a pressure gauge (Fig. 6). As shown the gauge may have a spring 20 which is movable in response to volume changes of the sac 3 to vary the air gap in a core 24 and thus change the mutual inductance between two coils mounted around the core. An oscillator (not shown) feeds one of the coils on core 24 and one coil of a compensating core. The other coil on cone 24 and the other coil of the compensator serve as series-connected sensing coils whose outputs are opposed. The sensing coils are connected to a phase sensitive amplifier which also receives a pilot signal from the oscillator. The gauge may be coupled to a pen recorder. Each sac 2, 3 may be detachable from the ends of the tube 1. If a plug and socket connection is used, then pressure within the system can be automatically restored on reconnection. The tube 1 may be made of plastics such as neoprene and the sacs of natural rubber. Alternatively the tube 1 and sacs 2, 3 may be defined between superposed welded sheets of a material such as p.v.c. enclosing a reinforcing tube of P.T.F.E., and in this case several tubes 1 and sacs 2, 3 can be provided side-by-side (Figs. 3 and 4-not shown) each for connection to a respective pressure gauge.

Abstract: 1,012,132. Electro - selective signalling. WESTERN ELECTRIC CO. Inc. Dec. 5, 1961 [Dec. 15, 1960], No. 43439/61. Heading G4H. A digit register used for producing an analogue signal is made to assume precise values at specific time intervals and is controlled by the differences to vary substantially uniformly between said specific time intervals. Initially a 5-digit decimal number is entered so that the three most significant digits are in coarse register 501 and three least significant in fine register 601. The difference between the initial registration and that for two seconds later is entered as a + ve or - ve number into difference unit 603 so as to set an auxiliary counter 644. High - frequency clock pulses are applied to counter 644 so that itcounts repeatedly from set position to full capacity and the stream of output pulses at 642 is representative of the difference. The analogue output of the register is in the form of timed pulses, i.e. PPM (pulse position modulated) or PDM (pulse duration modulated) with respect to a reference signal, Fig. 7A. The register is run down by a 5MC clock 612 through a binary-coded decimal counter 606. An output pulse on line 642 from a negative difference input opens gate 613 and closes gate 614 to transfer the input to 606 to the second stage if the count-down is to be accelerated, Fig. FC. If the count-down is to be slowed due to a positive difference input gate 614 is closed to lose an input pulse to 606. Specification 1,012,133 is referred to.

Title: Improvements relating to arrangements for the transmission of communication signals by pulse code modulation transmission
Inventor: BARROW CHRISTOPHER WILFED MERE
IPC: H03M1/00
Filed: 1964-10-27
Abstract: 1,059,150. Pulse code modulation. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 18, 1965 [Oct. 27, 1964], No. 43766/64. Heading G4H. [Also in Division H4] In the system for transmitting signals such as speech signals in pulse form the coder at the sending end samples the input and transforms it into a series of digits the first of which indicates the sign, the next two the amplification factor and the remainder the value. In the form shown speech input signals on a plurality of input lines are sampled sequentially and each sampled signal transmitted via lines L1, L2 (Fig. 1A, not shown) to an addition circuit and polarity indicator, the output from the latter being on one of two lines P1, P2 depending on whether the signal is positive or negative. If for example the signal appearing on line L2 is 2000 volts, the first input pulse at terminal T3 (Fig. 1B, not shown) to a digit ring transmits a pulse via terminal D1B to the transmission path TP to indicate that data is going to be transmitted. During the remaining seven digit intervals gates G8-G22 are selectively enabled by the output from the polarity indicator and the pulses appearing at terminals T3 and T4 to set or reset bi-stable triggers M1- N11 resulting in a pulse train 1011100 being transmitted to the pulse sending circuit and also resulting in the enabling of selected ones of the gates C1-G4 to enable switches S1-S4 to pass currents from the fixed value current producing elements, the switches multiplying the produced current by a fixed amount. The output from the switches is fed to an attenuator unit which feeds a signal of the corresponding voltage to the addition circuit AC for comparison with the sampled input during each digit interval. At the receiver (Figs. 2A, 2B, not shown) during the first digit interval a pulse arrives at terminal T10 to indicate the arrival of data. The following seven bits control gates GB5- GB16 and consequently control the setting of bi-stable triggers BM1, BM2 enabling gates GB1-GB4 controlling current switching means BS1-BS4 and bi-stable triggers BM3-BM8 which control fixed value current producing elements to determine the current that shall pass through the switching means. In an attenuator the output from the switches is combined to produce a voltage on line L5 corresponding to the input voltage at the transmitter. This voltage is fed to distributing and demodulating circuits, the outputs from which are speech signals on a plurality of lines.
