Title: Improvements in and relating to trip mechanism
Inventor: WARNER RICHARD MICHAEL
IPC: G05G7/02
Filed: 1964-01-17
Abstract: 1,007,744. Automatic reverse gear; cams; linkwork. CHARLES D. HOLMES & CO. Ltd. June 16, 1964 [Jan. 17, 1964], No. No. 2198/64. Headings F2D and F2K. An automatic control for a hydrostatic reverse gear comprises an output driven pinion 1 carrying adjustable stops 2, 3 which after a predetermined rotation of the pinion 1 engage and rotate a cam lever 4. Cam surfaces 5 on the lever 4 co-operate with a follower 19 freely rotatable on a lever 17 so that rotation of the lever 4 moves the lever 17 anticlockwise. A V-shaped element 16 pivoted to the lever 17 carries pins 23, 24, one of which engages a co-operating surface 25 or 26 on, and rotates a plate 7 when the element 16 is moved against the bias of springs 20, 21 by the lever 17. Rotation of the plate 7 acts through an arm 14 to operate a valve or switch 15 for ratio shift. The plate 7 is retained in the forward or reverse position by a spring-pressed pin 10 engaging a cam surface 9 on an arm 8 of the plate. Rotation of the plate 7 moves laterally a pin 22 to which the springs 20, 21 are connected and thus alters the bias on the V-shaped element 16 so that on subsequent movement of the element 16 the other pin 23 or 24 engages its co-operating surface to rotate the plate 7 in the reverse direction. Manual ratio shift may be effected by anti-clockwise rotation of a lever 27 which acts through a lever 29 and pin 30 to move the lever 17 anticlockwise. Specification 1,007,743 is referred to.

Title: Improvements in or relating to fuse-elements for the protection of electric circuits
IPC: H01H85/06
Filed: 1940-02-14
Abstract: 538,232. Fusible cut-outs. ARTIC FUSE & ELECTRICAL MANUFACTURING CO., Ltd., and ROSS, F. A. Feb. 14, 1940, No. 2789. [Class 38 (i)] A fuse element is made with a zone of increased resistance enclosed by a coating or mass of fusible material to absorb heat and delay fusion. The zone of increased resistance may be produced by reducing the cross-section of the element, by shot blasting, beating or work hardening it, or by alloying it with another metal which may be the coating material. The heat absorbing material may be a metal such as tin or cadmium or a material like wax or shellac, or both metallic and non-metallic materials may be used. If a metal is used it will, after fusion, alloy with the fuse element and reduce its current carrying capacity and so promotes fusion. If the element comprises two strips of different metals such as silver and copper they may be fused together at one point so that they alloy and form the high resistance zone, or they may be connected by the coating material. If the two metals are in series they are fused together and the junction forms the high resistance zone and carries the coating material. The coating may be applied by spray, melting, or welding.

IPC: H04S3/00
Filed: 1975-01-17
Abstract: 1497394 Recording and playback EMI Ltd 17 Jan 1975 [22 Jan 1974] 02947/74 Heading G5R [Also in Division H4] In a system for recording multichannel audio information a first channel signal L frequency modulates a carrier which is recorded in a first recording channel while a second channel signal R is inverted at 4, and frequency modulates a carrier which is recorded in a second recording channel. On reproduction from the recording the channel signals are demodulated at 8 and 9, the second channel signal is inverted, at 10, to restore its initial phase and the two channel signals are separated by filters 14 to 17, into components above and below 200Hz. The low frequencies of the two channels are combined, at 18, in the ratio 0À5 to 0À5 and the combined signal added to each of the high frequency channel signals, at 19 and 20, to provide two output signals, each containing the respective high frequency portion and a common low frequency portion, in which low frequency rumble, introduced into the channel signals by the mechanics of the recording process, has been cancelled. The loss of information by combining the low frequency components is negligible since the low frequencies contain negligible directional information.

Title: Improvements in and relating to change-over mechanism for four-stroke engines
IPC: F02B43/00
Filed: 1928-01-31
Abstract: 284,993. Maschinenfabrik Augsburg- N³rnberg Akt.-Ges. Feb. 7, 1927, [Convention date]. Four - stroke - cycle engines. - In gas engines which work at times with a compressed air supply, an atmospheric air inlet is closed and a changeover valve near the engine is moved before the compressed air can flow to the cylinders. This is effected by a piston 6 in the compressed air pipe; the piston has a collar 8 by which it rests on a seat 9 in the pipe. A rod 10 is connected to the piston and through linkage 12, 13 works the valve 3 of oil relay motors 4, 16. The piston has a projecting part below the collar; when the air under pressure enters the pipe 7 it moves the piston but the piston keeps the pipe crosed until the relay motors have moved. When the engine works on the normal four-stroke cycle a valve or throttle plate 17 enters the suction air inlet 22 as shown in dotted lines in Fig. 2<a>; the throttle valve 1 surrounding the engine inlet valve 24 has fully opened the atmospheric air ports 28 and air is drawn from the opening 23 above the piston 6 through the pipe 7 and chambers 19 and 20 of the distributor box 15. By this means any mixture which on the compression stroke is forced back from the cylinder into the chamber 19 together with any exhaust gases which may escape thereto are drawn into the cylinder on the suction stroke thereby preventing explosions in the inlet piping 7. When the engine is to work with compressed air this air enters through the pipe 7 and moves the piston 6 as described above and closes the air inlet 23. The relay motors 4, 16 move (i) the throttle 1, to close or throttle the atmospheric air ports 28 and (ii) the throttle 17 to close the connection 21 between the chambers 19, 20; the compressed air enters the valve box through the chamber 19 and gas is admitted through the passage 27.
