Abstract: 793,066. Traps. ECONOMIC WATER SOFTENERS, Ltd. Jan. 1, 1957 [Oct. 1, 1955], No. 27994/55. Class 33. A re-sealing trap for use with sinks and other liquid containers, comprises an outlet 4 and an inlet 5 which is connected to a dip-tube 1 the end of which terminates short of the bottom of flask 3. Sleeve 8, with a vent 12, surrounds the dip-tube, and is formed with lip 13 around the external periphery of its lower end which constricts space 11. The volume of space 11 is such that liquid which is trapped there during syphoning, will flow back to the bottom of the flask when syphoning ceases, and cover the end of the dip tube, thereby sealing the inlet tube. Slack-ening or tightening of the flask is facilitated by striking the radial peg 14 in the appropriate direction with a hammer.

Filed: 1936-10-19
Abstract: 468,172. Wireless receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 19,1936, No. 28430. Convention date, Oct. 17, 1935. [Class 40 (v)] In a method of converting frequency modulation to amplitude modulation, use is made of reactive circuits so tuned that the substantially rectilinear portions of their resonance curves intersect at the carrier wave frequency of the modulated wave to be handled. The signal is passed by normal receiving apparatus 2, 4, Fig. 1, through an amplitude limiter 6 and is applied in parallel to the control grids of the amplifying valves 8, 10 in whose anode circuits are circuits 12 tuned just below and 14 tuned just above the lowest and highest frequencies present in the modulated wave. Similarly circuit 16 resonates above the highest and 18 below the lowest frequency. The outputfrequency response from circuits 16, 18 is shown at A, B in Fig. 2 ; FC being the mean carrier frequency. The signals applied to the grids of the detectors 20, 22 are thus amplitude modulated, the outputs being combined in push-pull in T, amplitude and second harmonic distortion being balanced out. If switch RS is operated and the outputs are combined in parallel, amplitude modulation is received and frequency modulation balanced out.

Title: Improvements in or relating to safety devices for use in vehicles
IPC: B60R22/28
Filed: 1962-07-25
Abstract: 1,048,413. Safety harnesses. T. A. EGERTON. Sept. 3, 1963 [July 25, 1962], No. 28519/62. Heading A3V. A safety device for use in vehicles comprises a piston and cylinder connected to the vehicle and to a seat safety strap or to the seat and biasing means acting between the piston and cylinder restraining them from relative movement under the action of a tension load acting between their ends, the biasing means being such as to permit such relative movement under the influence of a tension load, above a predetermined value. The cylinder 12 is secured to the vehicle floor and the safety strap is connected to the piston rod 15. A spring 29 surrounding the piston road is biased by adjusting two rods 23, passing through holes in the piston and fixed nuts 25. Adjustments are read off scale readings 32 on the piston rod. When a sudden tension is applied to the strap the piston moves against the action of the spring and allows the strap to yield. When the tension is released, the spring returns' the piston and a one way ball valve 31 in the piston opens and and allows air,which has passed a sealing disc 21 on the piston to return to the piston rod side of the piston. In an alternative form the piston and cylinder is is connected between the vehicle floor and safety harness on a seat' which is mounted to pivot. The piston has a brake part which co-operates with wedge shaped brake pads on the inside of the cylinder, the braking effect increasing with movement of the piston. The initial spring bias is effected by rotating the piston rod with relation to a fixed nut adjacent the piston.

Abstract: 1467316 Control of D.C. motors HITACHI Ltd 28 June 1974 [2 July 1973] 28835/74 Heading H2J The series D.C. motor M, F of a railway tramcar is connected to an overhead feeder line L through a pantograph collector P and a regenerative braking circuit consisting of a thyristor chopper CH and members LF, LM, CF, DS, DB, reliable operation of this circuit when the motor is initially changed from a driving to a regenerative mode being ensured by an excitation circuit SA, RA, which supplies the field winding F from the line L during the start of regeneration, a typical cycle of braking being as follows: (1) When motor M is switched from its driving to its regenerative mode, switch SA is closed to supply the field F through resistor RA, reactor LM and the chopper CH (after its closure), the chopper mark/space ratio then being controlled by a closed loop system, Fig. 3 (not shown), to produce a desired large field current and a rapid increase of the voltage generated by the motor, the resistor RA acting as a current limiter during the period. (2) When the voltage generated by the motor has reached a predetermined level, e.g. after about 1 to 2 seconds, switch SA is opened and regenerative braking is produced at a desired rate by controlling the mark-space ratio of the chopper CH with the closed loop control system. When the chopper is conductive, series generator operation occurs through members M, F, LM, CH, DB and when CH is non-conductive, stored energy (mainly in reactor LM) is returned to the supply through the circuit M, F, LM, DS, LF, P, L, E and DB. The following modifications are also described: (1) Members F, LM are interchanged and resistor RA is connected to their junction point, Fig. 5 (not shown). In this case diode DB may be omitted. (2) Resistor RA is connected to the junction between members M, DB, Fig. 6 (not shown). (3) Diode DB is replaced by a switch (SB), which is open at the start of regeneration and closes when the generated motor voltage reaches a predetermined level, Fig. 7 (not shown). (4) Resistor RA is replaced by a reactor (LA) of inductance and resistance considerably greater than those of reactor LM, Fig. 8 (not shown). (5) Members M, F are connected in parallel with the series combination of a switch (SC) and resistor (RB), the switch being interlocked with switch SA for simultaneous closure and the value of resistor (RB) being such that the field F is also energized when the chopper CH is open, whereby the generated motor voltage is more rapidly increased, Fig. 9 (not shown). The modification shown in Fig. 10 use as second thyristor chopper CHA to supply and control the field current, a transistor oscillator, Fig. 12 (not shown), of variable frequency controlling the chopper CHA and having a switch (SI) which is closed at the start of regeneration (to start the oscillator) and opened when the generated motor voltage has reached a predetermined level (to stop the oscillator). When the motor is stationary, switch SA may be closed to obtain a D.C. supply for testing the chopper CH.
