Abstract: 409,591. Printing-surfaces. FOSTER & SONS, Ltd., J., and BRADSHAW, R., Soho Foundry, Preston, and YARDLEY, O. J., 54, Old Park Ridings, Grange Park, London. Oct. 16, 1933, No. 28577. [Class 100 (ii).] In a plate-clamping arrangement for a printing- cylinder, the centre margin ring is formed in two parts which are relatively adjustable to register the plates longitudinally of the cylinder, one part being adjustable from one end of the cylinder and the other part from the opposite end of the cylinder. Fig. 2 shows a part of the development of a four-phase wide printing cylinder. The centre margin ring comprises two parts a, b, Figs. 2 and 5 having plate-clamping teeth 14, the teeth on one part moving between the teeth on the other part. Each part is adjustable from the adjacent end of the cylinder bv a number of Screwed spindles 15 geared together by spur wheels 16 and intermediate wheels, one of the spindles being provided with a squared end 17 to receive a spanner. A clamping ring for the outer edge of the inner plate and the inner edge of the outer plate also comprises two parts c, d, operated by spindles 20 passing through sleeves 21 and operated by spur gears 23 and intermediate wheels, one of the spindles having a squared end 25. The inner ends of the spindles 20 are squared to engage in squared pockets 19 in screws 18. The sleeves 21 carry the dogs 22 for the outer plates and are connected together by spur gears 24 and intermediate wheels 26 one of which has a squared extension 27. Fig. 6 shows a modification by which plates differing in width by a column may be employed. A ring 35 of the width of a column is removably mounted in the cylinder and may be placed, as shown, to the left of the part c or to the right of the part d. To enable operative connection of the spindle 32 with the members c d to be maintained, in either position of the ring 35, the screw 29 has a squared end 30 engaging in a socket in a slidable sleeve 31 having a slot 34 engaging a cotter 33 on the spindle. The plates may be adjusted circumferentially of the cylinder by means of screws 37 mounted on bars 38 and having tommy heads engaging the edges of the plates. Specifications 351,970 and 363,571 are referred to.

Abstract: 381,727. Rotary engines. HAPKINS, D. N., 109, South Carondelet Street, Los Angeles, U.S.A. Oct. 17, 1931, No. 28910. [Class 110 (ii).] In an internal-combustion engine of the type illustrated two abutments 39, 40 are formed in the casing liner 60, and during the suction stroke alternate vanes 271 are held in the retracted position so that the amount of fuel contained in 90‹ of the working chamber is compressed into the combustion chamber 56 and one of the pockets 55 scooped out of the rotor R. The vanes 27, 27<1> have guide-pins 27c surrounded by compression springs 29, and legs 27b which in the vanes 27<1> are fitted with rollers 47 which co-operate with cam tracks 50 extending over the arc of 180‹ covering the suction stroke. L-shaped packing-bars 33 fit in two slots in each vane, one of each bearing against a side wall of the working chamber. Sinusoidal springs 34 are fitted under the bars 33. The inlet port 41 extends to a point 41a midway between the abutment 40 and the midsuction stroke point 42. The engine is lubricated by means of a hollow shaft having radial holes communicating with holes 26 in the rotor. The number of vanes may vary.

Title: An electrical control system
IPC: H02P7/03
Filed: 1958-09-09
Abstract: 884,767. Control of D.C. motors. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Sept. 9, 1958 [Sept. 30, 1957], No. 28910/58. Class 38 (3). An electric motor 1 is reversed by means of main transistors 4-7 connected in a bridge circuit. When both switches 32, 33 are opened, the transistors 4, 6 are conductive, their base currents passing through auxiliary transistors 14, 16. In this case the base currents of the auxiliary transistors flow through resistors 23, 25. The main transistors 5, 7 are non-conductive, the associated auxiliary transistors 15, 17 being in a like condition. The motor is therefore de-energized and is short-circuited by rectifiers 12, 13. The closure of switch 32 causes the base current of transistor 15 to pass through resistor 30, so switching on this auxiliary transistor and its associated main transistor 5. At the same time, the transistors 4, 14 are rendered non-conductive, so that the motor is energized through transistors 5 and 6. The motor is reversed by closing switch 33, the main current passing through transistors 4 and 7.

Title: Apparatus for operating up and over doors
Inventor: FISHER SIDNEY PATRICK
IPC: E05D15/42
Filed: 1964-07-14
Abstract: 1,039,666. Door operating appliances. E. POLLARD & CO. Ltd. June 28, 1965 [July 14, 1964], No. 28926/64. Heading E2M. An up-and-over door having a lever on the door connected to a unit reciprocated by an electric motor to move the door to its open or closed position has a coupling between the lever and the unit which is automatically released if the door movement is impeded. The unit comprises a cage 11 having rollers 12 engaging a track 13 and reciprocated by chains 15 connected to the electric motor drive. The chains are connected to a rod 14 carrying a post 16 positioned centrally of the cage by springs 17, 17a. Mounted on a bracket 18 secured to the post 16 are two abutment members 22, 23 between which is located a ball head 10 extending from a lever 8 attached to the door. When the motor is energized the chains 15 move the cage and one abutment member engages and moves the ball 10 and lever 8 to open or close the door. If the door movement is impeded, continued movement of the chains moves the cage and compresses one of the springs 17, 17a until the abutment (22 or 23) which is in contact with the ball 10 is able to pivot through a slot 31 (or 31a) whereby the ball and lever 8 are disconnected from the drive motor (Fig. 4, not shown). The abutments are spring urged to the positions shown in Fig. 3 so that the lever 8 is automatically recoupled during the next reciprocating stroke of the cage. Locking means is connected to the door operating mechanism so that initial movement of the mechanism releases the latches. Similarly, the final movement of the mechanism on closing the doors re-inserts the latches. The rollers 12 may be replaced by nylon shoes. The ball 10 may be guided in a separate channelshaped guideway to prevent it dropping downwardly when uncoupled.

Abstract: 1,164,957. Starting prime-movers; electric motors. SULZER BROS. Ltd. 20 June 1968 [20 June, 1967], No. 29476/68. Headings H2A and H2H. System for starting the engine of a dieselelectric locomotive by means of its A.C. generator includes an inverter controlled in dependence on the rotational position of the rotor of the generator. The generator 2 is excited by closing a switch 7 to connect it with a D.C. source 8. A.C. is now supplied by a thyristor inverter 21 equipped with chokes and smoothing capacitors (Fig. 3, not shown) and the phase and frequency of the A.C. are controlled by a unit 22 which receives signals from a photo-electric detector 23. The detector responds to both the position and the speed of rotation of the rotor of the generator 2. When the engine 1 fires, the inverter 21 is disconnected and the generator 2 supplies the traction motors F through a rectifier 13. During starting, this rectifier takes the return current from the generator. The switch 7 remains closed after the engine has fired so that excitation current can be supplied to the generator, and a regulator 9 reduces the excitation as the rotational speed of the generator increases.
