Title: Improvements relating to timing devices
IPC: A63H30/04
Filed: 1949-07-19
Abstract: 659,546. Actuation of switches. HUNT, P. H. July 19, 1949, No. 19023. [Class 38(v)] A time-lag switch for use in a, remotely controlled apparatus closes its contacts after a short time interval if no control signals are received. The switch comprises an arm 1 carrying a contact 3 rotated at a predetemined speed by clockwork, electric or other motor. A disc 4, coaxial with the shaft 2 and insulated therefrom by an insulating bush 5, carries a contact 6 and a slip ring 7. A coil spring 10, fixed between, but insulated from, the arm and the disc tends to bias them so that the contacts 3, 6 are apart as shown. An arm 11 has a brake shoe 13 and is biassed towards the disc by a spring 14. With the shoe 13 preventing the disc 4 from moving, the arm 1 in rotating partially winds up the spring 10 until the contact 3 engages the contact 6 to initiate the desired emergency operation. If, however, a control signal is received by the apparatus before the contacts close, an electromagnet 15 is energized and withdraws the brake shoe. This enables the disc 4 to rotate with the arm 1, and the spring 10 to relax. This switch is used to guard against failure to receive a control signal, and if it is desired to guard against a fault in the apparatus which would cause the electromagnet to remain permanently energized, the lever 11 may be provided with two brake shoes arranged so that in either position of the lever a shoe is bearing against the disc 4. Thus the disc 4 is only freed when the lever 11 is moving from one to the other of its positions.

Abstract: 1,129,573. Reactor pressure vessels. SOC. INDATOM S.A.R.L. 26 April, 1967 [27 April, 1966], No. 19158/67. Heading G6C. A reactor pressure vessel comprises a wall of prestressed concrete lined with a metal membrane which is directly in contact with the heat-transporting fluid circulating within the pressure vessel and is fabricated from plates which are assembled by welding, all the welded joints being subjected to a heat treatment which is similar to a prior heat treatment given to each plate and, between the lining membrane and the prestressed concrete wall, a heat-insulating layer which is traversed at the rear portion thereof adjacent the concrete wall by tubes for the circulation of a cooling fluid. The metal for the lining membrane possesses a high yield strength even at a relatively high temperature and a substantial ductile fracture strain. It is preferably a low-carbon nickel steel maintained in the martensitic phase and aged by heat treatment by virtue of the presence of addition elements such as molybdenum, titanium and cobalt. The lining membrane can be anchored either to the concrete or to the heat-insulating layer. An array of rods possessing good heat conductivity is mounted in the heat-insulating layer between the tubes, the purpose of which is to draw off heat towards the cooling fluid in the tubes. The tubes and rods are supported by the lining membrane anchoring members.

Abstract: 1,142,324. Spring power storing-mechanism. GEORGE ANGUS & CO. Ltd. 6 May, 1966 [10 May, 1965], No. 19606/65. Heading F2S. A pressure fluid-operated device, which may be employed e.g. as a shock absorber or vibration damper, but which is particularly intended to replace conventional springs in high voltage circuit breakers, comprises a housing 3, which is divided by spaced diaphragms 4, 8 into two sealed spaces 6, 7, the lower space 7 being filled with a fluid, e.g. propane, which is gaseous at normal temperatures and pressures but which is readily liquefied by pressure alone, and the space 6 being filled with a liquid, e.g. water, which is relatively incompressible. The propane is not readily soluble in water. The lower diaphragm 8, which is chosen to have a high chemical resistance to the fluid in the space 7, has a greater area than the rolling diaphragm 4 so that a plunger 1, 2, connected to the diaphragm, has a magnified displacement the plunger normally being secured, e.g. by an overload relay locking pin, to resist a pressure e.g. of 20001bs., and keep the propane in a highly compressed liquid state. Removal of the locking pin by an overload allows rapid vaporization of the liquid, the plunger 1, 2 being quickly driven to its extended position, Fig. 3, not shown. The device is assembled while the chamber is kept below the boiling point of - 45‹ C., for the propane, the locking pin being fitted before the device is allowed to acquire room temperature. The device can be reset by means of an hydraulic jack. The use of two diaphragms and the incompressible liquid prevents loss of the propane.

Title: Fuel injection pump and system for internal combustion engines
Inventor: BEDDOES GERALD NORMAN
IPC: F02D1/00
Filed: 1961-05-31
Abstract: 953,371. Fuel injection pumps; fuel injection systems. ASSOCIATED ENGINEERING Ltd. May 21,1962 [May 31, 1961], No. 19665/61. Headings F1A and F1B. A diaphragm type fuel injection pump comprises an apertured diaphragm 2, Fig. 9, and a cam-actuated plunger 3 reciprocable to close the aperture 2a and effect the delivery stroke of diaphragm 2 during part of its stroke, a control member 4 being movable to apply an adjustable static deflection to the diaphragm for controlling the output. In the embodiment shown, a diaphragm fuel pump 30 supplies fuel to the plunger side of diaphragm 2 via a filter 29a and an accumulator 29b, the fuel passing through aperture 2a until it is closed by plunger 3. Delivery is effected to one or more injections via a check valve 27. Control member 4 is movable by cam or wedge means in response to movement of an accelerator pedal or engine suction. Several pumps may be actuated by a single cam shaft and may be arranged in "V" or "X" formation, or may be arranged parallel to each other and actuated by an axiallyacting cam. In a system comprising one or more pumps each feeding one or more injectors, the pump output and an air inlet throttle 14 may both be controlled by the accelerator pedal 32, Fig. 9, or the throttle may be controlled by the accelerator pedal, and the pump output controlled by the engine inlet manifold pressure, Fig. 3. In the embodiment of Fig. 9, accelerator pedal 32 is connected to throttle 14 and pump output control member 4. For starting, member 4 is controlled manually or automatically through a knob 24 and an air pressure-compensating vacuum capsule 25. For running, depression of pedal 32 moves output control member 4 and opens throttle 14 by moving downwardly the fulcrum 15a of a link 15 between throttle 14 and a spring-loaded diaphragm 18 downstream of throttle 14. The action of throttle 14 and diaphragm 18 controls the manifold pressure at a substantially constant level according to the accelerator pedal setting. Change in pressure, due to change in engine speed independently of movement of the accelerator pedal, is compensated by the balancing action between diaphgram 18 and throttle 14. A governor 26 provides for fuel cut-off on the over-run. The contour for cam 23 in the linkage depends on the engine characteristics. In the embodiment of Fig. 3, the accelerator pedal controls the throttle and the pump output is controlled in response to the pressure downstream of the throttle by a spring-loaded diaphragm 10 connected to output-adjusting member 6. Spring 11 may be non-linear to provide extra fuel in the upper and lower speed ranges. A manual control 12 is provided for starting and matching the outputs of a plurality of pumps.

In a travelling-wave amplifier with the wave-guiding structure in the form of a helix, the helix 8, Fig. 1, is surrounded by axiallyspaced wave attenuating members 14 which subdivide the helix into sections, each of a length such that the transit time of the high-frequency waves traversing the section is small compared to a period of oscillation of the waves; the wave attenuating members are shaped so as to provide a matched aperiodic impedance termination for each section. The attenuating members are internally coated with loss material. Each attenuating member may form a drift tube, or a separate drift tube 19, Fig. 3, may be provided inside each member, the turns of the helix 8 being increased in this region to surround the drift tube. The attenuating members may be held at the potential of the helix, or at difference potentials. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which the helix is cut at spaced points, and the adjacent ends are doubled over to provide attenuating terminations. This subject-matter does not appear in the Specification as accepted.
