Abstract: 1,109,336. Recording and playback. SPETSIALMOE KONSTRUKTORSKOE BJURO " GAZPRIBORAVTOMATIKA ". 6 May, 1966, No. 20058/66. Heading G5R. Stray magnetic fields caused by flaws in a workpiece are recorded on a magnetic tape 24 which is then fed through a reading device comprising a plurality of magnetic heads 10, 10<SP>1</SP> arranged to be moved transversely across the tape, a cathode-ray tube (1, Fig. 1) for displaying a trace of the flaws and having a deflection system connected to horizontal and vertical scanning generators (3, 4) operating in synchronism with the movement of the magnetic heads and with the forward movement of the magnetic tape 24, and a further cathoderay tube (2) or tube trace which is arranged to provide a display of signals from the flaws in the shape of pulses and is associated with a further deflection system (12) connected to a switch (11) controlled by the movement of the heads so that signals from only one of the heads are used to produce the display on the further tube or tube trace. The switch (11) may be in the form of an optical system incorporating a light source 21, a photodiode 23, and a rotatable shutter 18 having a slit 20 and being mounted on the same shaft 15 as the magnetic heads 10, 10<SP>1</SP>. The angular extent of the slit 20 is such as to eliminate pulses produced when the associated magnetic head reaches or leaves the tape 24. The shutter 18 may have additional slits 19, 19<SP>1</SP> disposed round its periphery and equal in number to the number of magnetic heads 10, 10<SP>1</SP>, these additional slits co-operating with a second photodiode 22 to synchronize the horizontal scanning of the displays with the rotation of the heads. The scanning of a predetermined length of tape may be initiated by the pressing of a button 32 to engage a clutch 33 which is then locked until a latch 34 is released by the action of an electromagnet 35 after one revolution of a gear-wheel 30.

Abstract: 726,384. Reciprocating pumps. DOWTY EQUIPMENT, Ltd. July 20, 1953, No. 20112/53. Addition to 636,568, [Group X]. Class 102 (1). [Also in Groups X and XXX] In a fluid pressure telescopic strut, such as a pit prop (see Group X), the pressure fluid is delivered from a reservoir, formed within the ram 1, into the cylinder space 10, by means of a two-stage pump 9 which comprises outer and inner cylinders 11, 12 communicating with the reservoir through ports 20, 21, and having outer and inner reciprocating pistons 13, 14 each of which, during the initial extension of the prop, displaces fluid into the space 10 through non-return valves in the closure disc 8. Once the prop meets resistance to extension, pressure in the space 10 will increase and the outer piston 13 will no longer discharge into the space 10, but will return fluid into the reservoir through a blow-off valve 22 in a return passage 23. The pump is manually driven by means of a crankshaft 15, crank 16 and connecting rod 17.

Abstract: 600,360. Electromagnets. HEATON, F., HEATON, A. R., and HEATON, J. M. B. Aug. 6, 1945, No. 20134. [Class 35] [Also in Group XXXVII] In a plunger type electromagnet, the plunger and/or the fixed core member arranged coaxially therewith is formed of coiled magnetic strip the axis of the scroll being displaced endwise to form an external cone at one end and an internal cone at the other end, the scroll then being cut to give the required end surface. In the form shown, the plunger 20 and the fixed core member 19 are cut from the same rolled strip and are secured to the cup members 53 which have a sliding fit and may be of magnetic material or of non-magnetic metal to reduce hum, in which case the spring 56 also serves as a return flux path. The moulded head 17 secured to the plunger has a pin (not shown) at each side projecting into a slot in the fixed member for limiting the stroke and carries one, two or three pairs of contacts 18 engaging fixed contacts 41 and providing a double break for each pole. In a modification, the spring immediately surrounds the plunger above the upper coil flange and the return flux path may consist of several C-shaped members clamped about the coil and surrounded, if desired, by a non-magnetic metal sleeve, while the plunger may slide in a sleeve of similar material. The upper end of the plunger core may be moulded into the head 17. Rubber buffers may be inserted in the lower face of the head 17 to engage a plate on the top of the upper coil flange. Two or three such solenoids may be mounted together to form a unit, and the solenoids can be used for other purposes, e.g. brake actuation.

Abstract: 499,500. Aircraft alighting gear. AIRCRAFT COMPONENTS, Ltd., and BOUND, R. H. July 24, 1937, Nos. 20546 and 31621. [Class 4] In a retractable aircraft-undercarriage part pivoted, for retraction, about a fixed axis, the locking and operating means include a jack having lock-operating travel in continuation of its working stroke, the travel for unlocking causing an abutment carried by the part to register with a fixed guide to inhibit operation of the lock except before or after retraction and formed as a circular arc whose centre is disposed substantially in the pivot axis. In one form, a tail-wheel is mounted in forks 11 carried by a shockabsorber 10. The shockabsorber is mounted on an axle 12 which is held against rotation in mountings. Two brackets 23 are fixed on the axle 12 and carry a pin 25. Two aligned arcuate-slots 24 are formed in the brackets having a centre coinciding with the pin 25 and an extension 26. A hydraulic jack-cylinder is fixed to the shock-absorber. The piston-rod of the jack is extended upwardly to co-operate, when the wheel is extended, with a socket 21 and is extended downwardly to engage, through a pin 27, the slot 26 and, through links 28 and a slot 29, the pin 25. Downward movement of the piston frees the socket 21 and moves the pin 27 downwardly into registry with the slot 24, thus permitting retraction of the mounting. A further slot, similar to the slot 26, may be'provided at the other end of the slot 24. In a modification, the jack is connected between a fixed part and a sleeve movable on the shock-absorber and carrying the pins co-operating with the slots and the socket.

Filed: 1945-08-13
Abstract: <PICT:0600288/III/1> <PICT:0600288/III/2> The Specification as open to inspection under Sect. 91 describes a self-propelled machine for spreading varnishes, solutions and lacquers upon surfaces, comprising a storage tank 1, a screw 4 operating in a shoot 3 for controlling the discharge rate of the material and a shoot consisting of sections 5 and 51.  The section 51 is pivotally connected to the vehicle frame 8 as well as to the section 5, the free end of which is connected to a carriage 9 mounted on transverse rails 101, 102.  The carriage is moved transversely of the machine when a pad 141 on the end of a piston-rod of a piston 13 engages a chain 11.  The movement of the piston 13 is controlled by compressed air passing through a valve 17, the setting of which is controlled by a snap-action cam and a lever mechanism 18 operated by the carriage 9.  The thickness of the distributed strip of material is adjusted according to the inclination of a board which extends the width of the machine, whilst a scraper and roller may be attached to the rear of the machine.  In a modification, the shoot may consist of a single section, the free end of which moves in an arcuate path. In a further modification, a short inclined board may move transversely with the shoot and may be moved rapidly in a direction at right angles to the length of the strip when the shoot arrives at the end of the transverse travel in order to allow for the spreading of the next strip.  The above-mentioned use of such a machine does not appear in the Specification as accepted.

[Class 7 (iii).] In a combined injector and pump unit a mechanically actuated pump plunger 7 of constant stroke forces fuel from a chamber 8 through a valved nozzle 3, the suction valve 20 being opened mechanically during a variable period towards the end of the injection stroke of the plunger 7 to control the quantity of fuel injected. The plunger 7 is actuated by an arm 10 in opposition to a spring 9, the arm also actuating the suction valve through a lever 29 by means of a bolt 30, there being lost motion A between the head of the bolt 30 and the lever 29. An eccentric pivot 32 enables the timing of the valve 20 to be adjusted relative to the movement of the injection plunger 7. During injection the valve 20 remains closed, the injection valve being opened by the fluid pressure in the chamber 8 against the pressure of a spring 19. On the opening of the valve 20 the fuel is forced back towards the supply source, the injection valve closing automatically.
