Title: Improved testing device for internal combustion engines
IPC: G01L23/08
Filed: 1952-07-11
Abstract: 723,818. Indicating ignition and other working conditions. ZIEHR, W. July 11, 1952 [July 12, 1951], No. 17488/52. Classes 7 (2) and 7 (4). [Also in Group XIX] A testing device for internal combustion engines comprises a pressure gauge communicating with the interior of a metal-clad tube provided with a screwthreaded filling adapted to be screwed into a sparking plug aperture of an internal combustion engine so that the pressure gauge is in communication with the combustion chamber and the metallic part of the tube is in electrical connection with the mass of the engine and with one terminal of an electric light bulb. The other terminal of the electric light bulb is connected to the battery side of the contact breaker of the internal combustion engine. Means are provided for also selectively connecting the pressure gauge to the suction duct of the engine, the suction side of the fuel pump of the engine, or the delivery side of the fuel pump. The pressure gauge is of known construction capable of indicating both the reduced pressure of the suction duct of the engine or fuel pump, and the pressure of the delivery side of the fuel pump or the combustion chamber pressure. In the latter case the pressure gauge indicates the incremental pressure in the combustion chamber for corresponding angular incremental rotations of the engine shaft, thereby enabling the position of top dead centre of each piston to be checked. The electric light bulb 2, Fig. 2, indicates also the instant of ignition in the combustion chamber by lighting up the instant the contact breaker 4 of the ignition system opens.

Title: Apparatus for crimping electrical connectors on to electrical conductors
IPC: H01R43/048
Filed: 1945-07-10
Abstract: 601,068. Jointing by stamping ; shearing. AIRCRAFT-MARINE PRODUCTS, Inc. July 10, 1945, No. 17537. Convention date, July 15, 1944. [Class 83 (iv)] Apparatus for crimping electrical connectors on to conductors comprises means for feeding a series of connectors successively to a position between a pair of crimping dies and means for moving the dies together to effect the crimping operation. A wheel 68 having sprockets 70, which engage with the holes in the connectors intermittently, feeds a strip 20 of joined connectors up to a stop 38. In this position, 'stationary crimping and shearing dies 22, 40 co-operate respectively with reciprocating dies 24, 42 and serve to crimp the ferrule of the end connector of the strip on to a conductor (not shown), which has been inserted therein either manually or automatically and to sever the connector from the strip by removing a portion of metal from between the two lowermost connectors of the strip. Dies 24, 42 are mounted on a member 26, which is reciprocated from a treadle through rod 34, lever 32 and links 30, 28. Operation of the treadle also serves, through a sprocket 48 and chain 50 to operate a sprocket 52, loosely mounted on a shaft 54 and carrying a pawl 58 which drives a ratchet 56 on each downward movement of the treadle. A locking pawl 60 on the machine frame prevents a reverse movement of the ratchet. A spring connected between the shaft 54 and the ratchet is put under strain on each movement of the ratchet and serves to drive the shaft 54 and feeding-wheel 68 when the lowermost connector has been severed from the strip. The next connector is then fed up to the stop 38. A detent 72 carried by the frame of the machine, co-operates with seats 74 on the wheel 68 to prevent a rearward movement of the wheel and to assist the correct positioning of the strip. The machine may be operated by a pneumatic cylinder instead of a treadle, Specification 585,508 is referred to.

Title: Improvements in and relating to electric switching systems controlled by timing apparatus
IPC: H02J13/00
Filed: 1928-06-19
Abstract: 292,603. Boder, E. June 23, 1927, [Conve'ntion date]. Switching systems.-A rotating time-switch 12 at a central station, which is driven by clockwork mechanism through a shaft 2, sends impulses of current, e.g. once every five minutes, through an electric motor 10 adapted, at each impulse, to turn a master switch 24, 26 through two consecutive steps of 90‹ and, in so doing, make and break a circuit B branching off to distant secondary stations for the purpose of actuating rotary switches at these stations synchronously with the rotating switch at the central station. As shown in the Figure, the branching control conductors are associated with respective supply conductors A, A<1> leading to the distant stations. At the central station another branch of the circuit B passes through an electromagnet 9 driving, by means of pawl and ratchet gearing, the disc 3 of a station switch relay repeating the movements of the switches at the distant stations and adapted to co-operate with the uniformly running shaft 2 of the time-switch 12 in such a manner that an auxiliary switch 32 is closed by relative movement of 2 and 3 if 3 falls out of step owing to accidental interruption of the circuit B. This has the effect, as soon as the circuit is restored, of keeping the motor 10 in continual rotation and thereby sending impulses of current in quick succession from the rotating make-andbreak switches 24, 26 of the master switch to the electromagnets of the distant step-by-step switches until they have caught up with the shaft 2, the re-opening of the switch 32 indicating when this has taken place. Alternative control circuits are provided by way of hand switches 38, 40 through which the distant step-by-step switches can be synchronized when the automatic action is interrupted. Specification 266,508, [Class 139, Watches, &c.], is referred to.

Liquid, e,g. sea water, is evaporated in a series of evaporator stages lf . . . 1a by means of a countercurrent stream of air (or other gaseous vehicle) circulated through the apparatus by fan 4, and a mixture of vapour and air is withdrawn from each stage and led separately through valves 14a ... 14f to a multi-stage heat exchanger 2a . . . 2f where the vapour condenses. The condensate (desalinated water) is withdrawn from the heat exchanger by pump 7, and discharged from the system via preheater 9. Sea water is fed by pump 6 through preheaters 9, 8, through the coil traversing the heat exchanger 2, and through heater 3; and the heated water is then introduced into the first evaporator stage 1f. Part of the brine withdrawn from the last evaporator stage la is pumped back to the coil of heat exchanger 2, and the remainder is discharged from the system through preheater 8. The temperature of the sea water flowing from preheater 8 to heat exchanger 2 is controlled by thermostat 12. The temperature of the brine flowing between the evaporator stages is controlled by thermostats 15f . . . l5b. The process is preferably operated so that the difference between the temperature and/or specific enthalpy of the liquid and that of the air is maintained lower in the first evaporator stage than the last. An apparatus is described in which the evaporator stages and the heatexchanger are disposed in a common housing.

Title: Electric device provided with a switch which is designed as a discharge tube
IPC: H01J17/22
Filed: 1977-05-02
Abstract: 1533198 Switching circuits for consuming devices PHILIPS GLOEILAMPENFABRIEKEN NV 2 May 1977 [5 May 1976] 18214/77 Heading H2H [Also in Division H1] A discharge tube switch applied to switch a device comprises two electrodes 9, 10 sealed in rare gas, possibly with Hg vapour, and with a hydrogen getter such as Ti or Zr which reversibly evolves H 2  when heated: increase of H 2  pressure increases the working voltage of the tube, exceeding the applied voltage and so breaking the circuit. The getter may be on one or both electrodes or may be separate. The getter temperature, e.g. 300-500 C., may be controlled by the heat of the discharge, by an external or internal heating element, or by the local ambient. The switch 8 heated by the discharge may be applied to start a ballasted 3 A.C. discharge lamp 4 with thermionic electrodes 5, 6, the reduced p.d. across the lamp after ignition serving to prevent further discharges in the switch which otherwise ignites, heats and extinguishes cyclically. Similarly (Fig. 2, not shown) the switch may short a charged capacitor through the primary of an autotransformer, the pulse in the secondary when the switch extinguishes being applied to the starting electrode of a lamp. With separate getter the switch as a thermostat mounted in an oven can switch on an oven-heating element and switch off at a required temperature (Fig. 3, not shown). Similarly a heater winding applied to a separate getter but in series with the main electrodes can cause an incandescent lamp in series to cycle on/off (Fig. 4, not shown). A switch with external heater can be used to switch off a thyristor (Fig. 5, not shown). Three such switches may be connected with the heater of one in series with the main electrodes of the next as a ring oscillator (Fig. 7, not shown). The switch itself may have a starter electrode usable to initiate a discharge at a selected instant (Fig. 6 not shown).
