The work carriage 17 moves in the X direction on a further carriage 15 movable in a Z direction. The carriage 17 is moved by screw and nut drive 28, 32 from a motor MX. The end of the screw 28 drives through a pressure operated brake 34, a clutch 42 and gearing 47, 48, 51, 52, &c. a set of transducer drums A, B, C, shown for example, for the carriage 15 on Fig. 2. The drums have a pattern of perforations that are read by a fluidic reader member 93, 94, 95 to provide a position information signal. The programme in tape form (Figs. 7 and 8, not shown) includes a block of instructions for X, Y, and Z movements. The tape is advanced step-wise by a fluid pressure operated rack 81 which rotates through a ratchet drive a wheel carrying pegs 77 which engage a row of perforations in the tape. A fluidic control pressure is passed from a chamber 86 through a particular hole pattern in the tape I to tubes 90. These tubes provide the position instruction signal. A digit read and null circuit (DRN) (Fig. 21, not shown) receives the position instruction and position information signal and control valves are operated to stop a movement only when parity between the signals is reached. The control also provides means for rapid or slow feed movements by controlling restrictors in a pressure fluid control circuit. A visual indication of the programme is provided (Figs. 25, 26, not shown) by a fluidic circuit and visual numerical display device. The spindle carriage 13 is moved vertically by a hydraulic cylinder M2 and position rod 21 with control provided by limit valves 217 and adjustable member 198. The spindle is rotated by electric motor 23 and automatic and manual operation of the motor is provided for in the control circuit (Fig. 28, not shown). The invention may apply to drill presses, milling machines, lathes, boring machine and grinders. Reference has been directed by the Comptroller to Specification 1,252,729.

A pump, e.g. for pumping blood, comprises a pair of flexible tubes 1, 2 fitted with valves 3 .. 6, and alternately compressed by a presser 10 reciprocated by a crank 9. The amount of liquid pumped is controlled by limiting the distortion of the side of the tubes 1 and 2, opposite to the side actuated by the presser, by flexible chambers 12, 13 containing fluid under a variable pressure. The chambers 12, 13 are supplied with pressure fluid through a pipe 20, valve device 19 and pipe 18. To control the pressure in the flexible chambers a manuallyadjustable by-pass valve 24 is provided, and in addition a throttle needle valve 27 is actuated by a lever 31 connected to a diaphragm 35 forming the base of the suction vessel 34; this arrangement prevents the level of the liquid in the vessel 34 from falling below a certain level. The throttle valve 27 may pass through its seat and further movement of the lever 31 actuates a piston valve 26 to open the pipe 18 to atmosphere. The output of the pump may be controlled by placing the chambers 12, 13 between the presser 10 and the tubes 1, 2.

Filed: 1951-11-28
Abstract: 698,993. Slub catchers. MOOS, A. Nov.28, 1951, No. 27903/51. Class 120(ii) A knot or slub catching device comprises two knives 11 and 12, carried on holders 7 and 8 respectively, the lower one 7 being fixed relatively to the base plate 1 by which the device is attached to a spooling or singeing machine, the upper one 8 being pivoted at 9 and urged towards the lower one by a spring 10. Coacting abutments 15, 16, Fig. 3, maintain a separation between the knives to form a slot 13, the abutment 15 being in the form of a screw to allow adjustment, and a pointer and scale 14 are provided to give visual indication of the adjustment. The thread 5 is guided through the device by guides 2; 3 and a tension device 4 and meets the knives at an angle of about 35 degrees. The slot is formed so that it narrows slightly in the direction of travel of the thread. A screw 23 is mounted on a member 24 attached to the lower knife at 25 in such a way that its inner conical end is level with and points toward the slot 13. The knives 11 and 12 are provided with enlarged portions 11<SP>1</SP> and 12<SP>1</SP> respectively, the portion 11<SP>1</SP> being cut away at 19 to form an aperture the bottom of which slopes upwardly at 11 degrees to the horizontal and which houses a roller 21, retained within the aperture by a cover plate 22. The diameter of the roller is such that it protrudes slightly into the slot. When a thread having a knot 26 of undesirable size is passing through the device, the knot will catch in the slot and slide along the knife edge until it catches between the screw 23 and the knife edges and the thread snaps-see the three positions a, b and c, Fig. 6. A thickened portion 27 of a thread will catch in the slot, slide along the slot and in so doing engage the roller 21 which is rotated by the thread along its upwardly inclined path to such a position where it clamps the thread against the upper knife 12, so causing the thread to snap.

Title: Improvements in or relating to producer gas generators
IPC: C10J3/80
Filed: 1939-10-14
Abstract: 535,706. Gas-producers. MORRISON, A. C.. and MORRISON, A. E. Oct. 14, 1939, No. 27924. [Class 55 (i)] A gas producer for supplying gas to internal combustion engines has a pilot air inlet which is constantly open, and a main inlet of larger cross-sectional area which is only open when the engine is under load, the pilot inlet preferably being arranged within the larger inlet. Air is admitted through main and pilot inlets 8, 7 and passes upwardly and obliquely across the fuel bed, the gas being withdrawn through a perforated screen 5 and outlet 4. An annular baffle 3 supports the fuel in the body '1. The pilot tube 7 is open to the atmosphere, but the air reaching the main inlet 8 when suction on the fuel bed is increased, is controlled by a spring-pressed poppet valve 18 and a butterfly valve 17, the increased air supply entering the fuel bed through an opening of larger extent than that provided by the pilot tube which operates alone when an engine using the gas is idling. In Fig. 4, the pilot tube 21 is provided with an external screw thread 23, so that, on rotation, the tube is caused to move forwards or backwards and close or open the annular passage between a conical nose-piece 22 and a chamfered face 13 of a sleeve 12. Rotation of the tube 23 by an arm 24 is effected either by a suction pump from the engine, or by direct connection with the engine throttle, so that air enters only through the pilot tube 21 when the engine is idling. In Fig. 6, air inlets 34, 35, 36 of decreasing bore are provided, the air to which is controlled by openings 34a, 35a, 36a in a slide valve 38 operated by a piston 40 actuated by engine suction applied through a pipe 48. When the load on the engine increases, the piston moves against spring 42 and causes openings 35a, 34a in turn to register with inlets 35, 34. Other modifications relating to valve means for controlling the air supply are described.
