Title: Improvements in or relating to hydraulic shock absorbers for vehicles especially motor vehicles
IPC: F16F9/24
Filed: 1932-10-14
Abstract: 408,958. Hydraulic shock-absorbers. DEUTSCH, F. A., 27, Rankestrasse, Berlin. Oct. 14, 1932, No. 28753. Convention date, Oct. 14, 1931. [Class 108 (iii).] An hydraulic shock-absorber for vehicle s comprises a movable damping-member separating an operating-chamber and a refill chamber, or working in an operating-chamber communicating with a refill chamber, and a transfer passage between the chambers so proportioned or controlled that transfer of liquid from the refill chamber to the operating-chamber, to keep the operating-chamber filled with liquid, takes place during slow body oscillations but is so delayed or prevented during rapid wheel oscillations as to provide an inactive zone in the shock-absorber during such rapid oscillations. Fig. 1 shows a single-acting piston-and-cylinder shock-absorber wherein the piston 3 is reciprocated through links and levers by relative movement of the frame and axle. A narrow passage 5<a> and a passage 5 closed by a ball-valve 6 and interchangeable nozzle 7 are provided in the piston, while the refill chamber b above the piston is only partly filled with liquid. On upward movement of the piston during slow body oscillations the liquid passes from the chamber b through the passages 5, 5<a> and fills the space a beneath the piston so that on the following downward movement damping occurs. On upward movement of the piston during rapid wheel oscillations however there is not sufficient time for the liquid to pass through the piston and therefore on the following downward movement damping does not occur. Dimensions of one form of such a shock-absorber are given in the description. A double-acting rotary vane shock-absorber is shown in Fig. 2 wherein the refill chamber b is separated from the parts a<1>, a2 of the working chamber by a partition containing narrow passages y, z, and passages 5, 5<1> having non-return valves, the passage 5 being adjustable exteriorly by a member 8. On clockwise movement of the vane x liquid is forced from the part a2 through passage y into the chamber b thus damping the movement of the vane. If the movement is rapid there is no time for the liquid to pass through passages 5, z into part a<1>, so that there is no damping on the return movement of the vane. During the rapid return movement, however, liquid passes through the passages 51, y into the part a<2>, the passage 51 being sufficiently large to permit this so that on the subsequent rapid clockwise movement liquid is again forced through passage y thus damping the action. In a further construction of the double-piston type an inertia-controlled, spring-pressed, apertured valve 9, Fig. 3, closes the transfer passage 5 between the refill and operating-chambers b, a during rapid wheel oscillations, but remains open, due to the spring-pressure 10, during slow body oscillations. The shock-absorbing action is adjustable by throttling members 11, 12.

Title: Improvements in and relating to protective apparatus for electric circuits
IPC: H02H3/30
Filed: 1931-10-20
Abstract: 392,596. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Bivens, M. E. ; 17, Glen Avenue, Scotia, New York, U.S.A.) Oct. 20, 1931, No. 29141. Convention date, Oct. 20, 1930. [Class 38 (v).] Relates to the protecting of circuit sections, particularly against earth faults, by means of high frequencies superimposed on the line at both ends, the frequency being transmitted only during alternate half-cycles of the circuit current and being received at the other end by a receiver adapted to receive only during alternate half-cycles of the current at this end, as described in Specification 274,070, [Class 38 (v), Electric 'switches &c.]. According to the invention the range of phase displacement between the currents at the two ends over which the circuit-opening operation due to fault may be effected is extended without causing unwarranted circuit interruptions. Instead of installing a single receiver at each end a dual receiver R is provided. The valve 51 receives through its connection with the line a measure of the current (in the example shown ground fault current) as transmitted to it through the line by the valve transmitter T at the other end which transmits alternate half waves. A subordinate receiver consisting of a valve 52 is so connected through the coupling transformer 47 as to receive the other half wave, but as this receiver would receive also from its near-bv transmitter this is compensated for by connection with a second compensating valve 53. The receivers are connected up respectively to the two differential windings of a differential polarized relay 19 which is shown closed in the, trip-circuit prepared position. When the fault relay 9 closes also, the trip circuit is complete but with through faults the differential relay closes, on the alternative contacts 26. By these means the opening of the circuitbreaker at the end of a section may be effected over a range of phase-angle difference between the fault currents at the ends of a section exceeding 180. The differential relay 19 may be that described in Specification 182,769, [Class 38 (v), Electric switches &c.j.

Title: Improvements in carburetting apparatus for internal combustion engines
IPC: F02M1/00
Filed: 1922-10-26
Abstract: 187,981. Regard, E. Oct. 28, 1921, [Convention date]. Vaporizers, external.-The main nozzle is supplied with vaporized fuel by a single conduit which, near the base of said nozzle, is branched to supply a by-pass or slow-running nozzle. Fuel from the float chamber 2, Fig. 1, passes by a conduit 3 open to the atmosphere at 4, to a submerged nozzle 6 in a hermetically closed vessel 5 and the mixture of air and fuel then passes through conduit 8, where it is vaporized by exhaust gases in chamber 33, to the main nozzle 10 provided with a cock 9. A branch 15 supplies a by-pass 18 on the engine side of the throttle valve 14, said by-pass having an additional-air inlet pipe 17 provided with a funnel 16 into which petrol may be poured to facilitate starting when a heavy fuel is used. An arm 22 on the throttle valve has a ball-and-socket joint 23 which slides over a rod 24 pivoted to a spring-loaded arm 28 on the cock 9. The instant at which the arm 28 is moved is determined by the position on the rod 24 of an adjustable stop 25 which is engaged by the joint 23. The nozzle 10 discharges into the inlet end 11' of a Venturi passage 11. The spiget of the cock 9 is a loose fit in its shell, so that when the throttle and cock are closed, air may pass from the inlet 11<1> through the cock to dilute the by-pass mixture. The fuel is heated by the apparatus shown in Fig. 2, which consists of a single casting 1 with fuel passages around which exhaust gases circulate at 33. The emulsified fuel enters at 7. the main nozzle is shown at 10 and the by-pass at 31, the flow to the latter being controlled by a screw valve 30. The conduit 17 in this case supplied hot air to the by-pass mixture. The casting 1 may be of iron and of such dimensions as to ensure stability in the temperature.

Title: Method of Measuring the Power Developed or Absorbed by an Engine and Apparatus for Carrying Out this Method
IPC: G01L23/08
Filed: 1968-06-19
Abstract: 1,166,987. Measuring engine performance electrically. SOC NATIONALE DES PETROLES D'AQUITAINE. June 19, 1968 [June 29, 1967], No. 29299/68. Heading G1N. The power or energy developed or absorbed in the cylinder of an engine is determined by developing a D. C. signal indicative of the pressure of the gas therein which is provided with a polarity dependent on whether it is measured during increase or decrease of pressure and integrating the resultant signal. The output from the pressure pickup 1, e.g. a Piezo-electric, capacitative or variable resistance pickup, is supplied via voltage shaper 2 to a sign changer 3 which changes the polarity of the signal in dependence on the direction of movement of the piston. To this end the device 3 is energized by pulses from a generator 4, supplied by device 6 which generates a pulse at the top and bottom dead centre of rotation of the engine, such that it changes the polarity of the output each time it receives a pulse. The output from device 3 is then integrated at 7. To ensure that the integral is positive, i.e. that the pressure signal is positive for increasing pressure and negative for decreasing pressure, the polarity of the integrator is checked in sign controller 8. If it has negative polarity the controller 8 emits a pulse to the generator 4 to block the next pulse so that the polarities of the two parts of the pressure signal are reversed. The output from 8 is then transmitted to an integrating memory device 9 which is interogated at predetermined intervals. Simultaneously the energy supplied to the engine is sensed by transducer 15, e.g. a flowmeter sensing the fuel flow-rate or a voltmeter sensing the elctrical energy supplied &c., whose output is fed via voltage shaper 16 to integrator 17 supplying a memory 18 similar to memory 9. The two memories are interogated at intervals and the recorded quantities are, after proportionality correction, fed to recorders 12, 20 and divider 14 whose output, recorded at 22 indicates the efficiency of the engine. The output from generator 4 is also recorded at 23 to indicate the rotational speed of the engine.

Title: Method of producing ions having nuclear spins predominantly orientated in one direction

Filed: 1963-07-24
Abstract: 1,042,976. Ion sources. COMMISSARIAT A L'ENERGY ATOMIQUE. July 24, 1963 [July 28, 1962], No. 29327/63. Heading H1D. [Also in Division G6] In a method of producing a beam of ions, e.g. protons or deuterons, having nuclear spins predominantly polarized in one direction, the atoms of an atomic jet issuing from a device 7 are first separated according to their electron spins by a Stern and Gerlach type 6-pole magnet 9 and then subjected to a " weak-field adiabatic passage " in the space between two polepieces 15, 16 where there is a constant transverse magnetic field varying in strength linearly in the direction of atom flow and where magnetic dipolar transitions are induced by a high-frequency electromagnetic field produced by the coil 21. To accomplish this latter step the dipolar transitions must occur between energy levels for which the energy difference varies linearly with the average strength of the constant magnetic field, this average strength lying in the range of 2 to 25 oersteds in the case of protons and in the range of 2 to 15 oersteds in the case of deuterons. The polepieces 15, 16 are surrounded by coils 17, 18 producing a uniform component of the magnetic field and carry plates 19, 20 in which are housed coils producing a non- uniform component, i.e. producing fields aiding and opposing the main field to obtain the required linear variation. The polarized atoms may, in addition, be passed through a " strongfield adiabatic passage" (H=1030 oersteds protons; H = 950-1110 oersteds, deuterons) within cavity resonator 23 and possibly through an adiabatic passage in chamber 28 before passing to an ion source, e.g. of the magnetron type within the vacuum chamber 29 of a cyclotron in which the atoms are ionized while preserving their nuclear polarization. In variations of the method a strong-field adiabatic passage may be passed through before a weakfield adiabatic passage.

Liquid to be filtered enters at 6, Fig. 1, and flows through a port 19 and passage 18 to a half circumferential groove 14 in the upper surface of a rotatable cylindrical valve block 9. It flows inwards through a cylindrical metal gauze filter element 23 and is discharged at 5. The inlet space communicates also with similar ports 20, 22 (not shown), connected to similar grooves 15, 17 (not shown) respectively, so that inward filtration also occurs through elements 24 and 26. A portion of the casing incorporating a reflux passage 7 is in continuous contact with the valve block 9, the passage 7 extending circumferentially a little beyond either edge of a fourth port 21 communicating with the outside of element 25. Liquid present in outlet 5 causes back flow through element 25 to passage 7. A valve in passage 7 may be closed to render element 25 wholly inoperative. A click-stop arrangement 62, 66 serves to locate valve block 9 in any one of four positions for back-flushing of any element. A further position may be provided, where passage 7 is blanked off and all elements are in use. In Fig. 3 (not shown), the valve block 9 is fixed and a valve member within it may be turned so that a radial apertured part of it may communicate with any one of five ports which in this case open to the inside of block 9. Communication with a central reflux passage is provided by telescoping a tube upwards into the lower part of the valve member.
