Title: Improvements relating to reciprocating pumps
IPC: F04B23/10
Filed: 1938-10-31
Abstract: 509,039. Reciprocating pumps. VARLEY, C. H., and VARLEY PUMPS & ENGINEERING. Ltd. Oct. 31, 1938, No. 26533/37. [Class 102 (i)] Pump pistons c', c<2> are actuated by levers l<1>, l<2> integral with a boss w<1> which carries levers k<1>, k<2>, having rollers j<1>, j<2> engaging cams h<1>, h<2> which are of similar shape and arranged 90 degrees out of phase with respect to the cams, the pistons c<1>, c<2> reciprocate 180 degrees out of phase with each other. A similar pair of pistons actuated in a similar manner are located adjacent those shown and the cams are shaped so that a constant delivery is obtained. Each piston adjacent the pistons c<1>, c<2> is 90 degrees out of phase with the piston c<1> or c<2> and the pistons have reduced portions n co-operating with ports s, t, u so that each piston serves as a slide valve for the adjacent cylinder. The cams have concentric portions so that the pistons remain stationary at the ends of their strokes. The valves are also provided with lap so that the pressure in the pump cylinders will reach delivery pressure before the valves are opened. The pumps may be supplied by a feed pump.

Title: Improvements in or relating to systems for generating data representative of the instantaneous angular position of a rotating body
Inventor: PARKER BERNHARD DOLLMAN
IPC: H03M1/26
Filed: 1959-08-04
Abstract: 879,475. Electric selective signalling systems. DECCA RECORD CO. Ltd. July 29, 1960 [Aug. 4, 1959], No. 26540/59. Class 40 (1). A system for generating data representative of the angular position of a rotating body  comprises means for generating main position marker pulses at a series of equally spaced angular intervals of rotation of the body to indicate when the body passes through each of these positions, means for generating identification pulses between the marker pulses to distinguish and identify the various main marker pulses and means for generating separate fractional indicating pulses between the main marker pulses to mark when the body passes through each angular position corresponding to a predetermined sub-division of the angular interval between the positions at which the main marker pulses are generated. As described two photo-electrically sensed discs 13, 14, Fig. 1, on a shaft 12 are used, one disc 13 produces regularly occurring main marker pulses 20, Fig. 2 (a) and the other disc 14 regularly occuring fractional indicating pulses 23, Fig. 2 (b) except that at the time when a main marker pulse occurs no fractional pulse occurs. As shown there are thirteen fractional pulses between each pair of main marker pulses and by counting both the main marker pulses and the fractional pulses the position of the shaft 12 could be determined. To avoid the necessity of counting the main marker pulses however, each is preceded by identification pulses 21, Fig. 2 (a) which identify, or label, it, and as described, these occur and are significant in combination, during the period occupied by the first eight fractional pulses after the preceding main marker pulse. Thus the eight fractional pulses which occur after each main marker pulse function as clock-pulses for interpreting the identification pulses. During the period between main marker pulses which is not occupied by identification pulses, other data such as pulses 24 can be transmitted. As shown in Fig. 1, the pulses from the two discs are applied to two tone generators 30, 31 and subsequently transmitted, either by radio or land line, to a receiver where the identification pulses are decoded by a device 36 and the fractional pulses are counted by a device 37, the counter being reset by each main marker pulse.

A mucking out implement comprises a dung pusher 6 and a reciprocating drive member 2 extending the length of the channel to be cleaned and having dogs 4 which engage a tube 9 effecting intermittent travel of the pusher 6. The pusher 6 comprises pivoted wing(s) (7) Fig. 1 (not shown) which are extended or folded depending upon direction of pusher travel, and in one embodiment also carries a pivoted tube 9 containing balls 10 and a slidable switching element 12. Operation. In the position shown, movement to the right by the reciprocating member 2 moves the pusher 6 with its wings extended, the dog 4 abutting end 9'. No movement of the pusher occurs when member 2 moves to the left when an advanced dog 4a engages the end 9'. Thus the pusher experiences interrupted rightwards travel until a stop 22 engages a face 14' of the element 12 causing movement of the element 12 to the left. The tube 9 pivots, further reciprocation causing the pusher 6 to move to the left, the wings being folded, until a similar stop 22 is reached. In a modification, pawls attached to the ends of the tube 9 engage the dogs 4, 4a &c pivoting of the tube 9 being caused by bars fixed to element 12 hitting an extension on the axis of the tube 9. In a further modification, a pivoted body of inverted triangular cross-section replaces the tube 9. Its apex engages the dogs 4, 4a &c, undesired rotation of the body being prevented by a bolt fixed to the element 12 which engages an end of the base of the body, the end determining the direction of travel of the pusher 6.

Abstract: 463,692. Discharge devices. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 2, 1935, No. 27201. Convention date, Oct. 3, 1934. [Class 39 (i)] To prevent lateral movement of the arc in a device 5, which is operated in a position other than vertical, a magnet is arranged above the device and comprises a coil 6 wound on a channel-shaped core 4, the sides of which converge to produce a field which has a steep gradient. The high-pressure lamp 5 and a brass or aluminium reflector 3 are secured to a socket arranged within a housing. A coil 8 may be wound on a sheet-iron core 7 which is supported by the reflector through brackets of non-magnetic material. The coils 6, 8 are connected in series with the lamp to produce opposite fields which neutralize each other a short distance below the lamp axis. and prevent movement of the abnormal arc which is formed upon ignition. In another form, the core 4 and coil 6 are surrounded by a channel-shaped sheet-iron member. The field at the middle of the tube may be weakened by holes in the central portion of the core 4. A starting electrode on the arc tube consists of non-magnetic gauze. The coils 6, 8 may be connected in series with the secondary of a transformer, the primary of which is connected in series with the arc tube ; the transformer is adapted to be saturated by the normal arc current. The Specification as open to inspection under Sect. 91 states also that fields may be produced by polished conducting vanes arranged above and below the lamp and connected in parallel across the secondary of a transformer, the primary of which is in series with the arc tube. The vanes may be spaced at different distances from the tube or may be of different sizes ; the lower vane may be dispensed with. This subject-matter does not appear in the Specification as accepted.
