Title: Improvements in and relating to brush holders for dynamo electric machines
IPC: H01R39/40
Filed: 1927-11-28
Abstract: 281,652. British Thomson-Houston Co., Ltd., (Assignees of Simmons, H. 0.) Dec. 1, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Brushes; brush - holders. -A brush-holder is fitted with a device for indicating the pressure with which the brush is forced against the commutator or slip-ring. In the form shown, the device takes the form of a rod 14, with index notches 15, carried by the brush 1. The brush is urged through the box 4 by a compression spring 10 bearing at its lower end on a brush follower 12, to which the index rod is secured, and at its upper end on a sleeve 11 in a movable yoke 8. This yoke has inturned extensions 9 travelling in grooves 6 in the sides of the holder structure 3 and, under the action of the spring, it enters one or other of a series of grooves 7 in the face of the structure 3. The rod 14 protrudes through the sleeve 11 so that inspection of the projecting notches 15 enables the spring pressure to be known. To alter the spring pressure, the front edge of the yoke 8 is pressed down to rock it about the projections 9 and free it from the groove 7 in which it happens to be engaged. It is then moved up or down and re-engaged with another groove 7 to give the required pressure. The member 3 is secured to the machine by any means, such as by screws entering the holes 13.

Title: Internal Combustion Engines

IPC: G01L3/24
Filed: 1967-07-12
Abstract: 1,155,909. Measuring power electrically. INSTITUT FUR SCHIFFBAU. July 12, 1967, No. 32108/67. Heading GIN. Each cylinder 1 of an I. C. engine has an associated Piezo-electric pressure transducer 2, and the power output of a cylinder is determined by connecting its transducer 2 via a switch 5 to an integrating amplifier 13, an inverter 12 being included in the amplifier input by operation of contact 6" of a relay 6 during piston movement in one direction, and not included during piston movement in the other direction. The amplifier output thus represents the difference between the integrals of two successive portions of the pressure/time characteristics of the cylinder, and is said to be proportional to the area of the closed loop curve which would show pressure against piston displacement, and which is related to power output. The relay 6 is operated by whichever of the switch arms 3 has been selected by the switch 5 to connect a voltage U a  to the relay. The switches 3 are cam operated by a cam (4, Fig. 2, not shown) connected to the crank-shaft, one switch 3 corresponding to each cylinder. A stepping switch 7 is stepped one position for each operation of a contact 6' of the relay 6, and opens contacts 8' after a predetermined number of cylinder operations. Actuation of a switch 11 to a position II causes the voltage U a  to be supplied to an alternative set of switches 10 operated by a cam 14, each switch 10 again corresponding to a particular cylinder and causing a voltage pulse to be produced at X to trigger a CRT trace. The voltage to be observed on the trace is connected to terminal Y via switch 11 from the desired transducer 2. The relay 6 is now inoperable and no power reading is obtainable, but instead a pressure/time curve is observable on the CRT.

The piston 2, secured on a piston rod 4 between two conical supporting discs 5, 6 by a nut 7, has an inner chamber which accommodates a supporting member 19 with spherically-curved ends which co-operate with the sets of springs 20, 21, the pressure ports 13<SP>1</SP>, 14<SP>1</SP> being distributed in evenlyspaced concentric groups. Corresponding outer groups of ports 13, 14, controlled respectively by valve discs 15, 16, are provided with apertures 17, 18 which correspond with the inner piston ports 13<SP>1</SP>, 14<SP>1</SP> when the piston 2 moves downwardly for low-pressure damping the gas flows through the openings 18 and raises the low-pressure spring plates at a pressure of approximately 150 k.g. and then passes through the outer ports 13 and around the disc valve 15 into the high pressure space 12. High pressure damping, with corresponding upward movement of the piston 2, causes gas to pass through the openings 17<SP>1</SP>, 13 and around the high pressure springs 20, which are biased to about 400 k.g. and through the openings 14 and past the valve discs 16 into the lower space 11.
