Title: Improvements in or relating to differential fluid pressure motors
Inventor: TOMLIN ROBERT DERRICK
IPC: F01C9/00
Filed: 1950-02-09
Abstract: 685,554. Oscillating-vane motors. MAGNATEX, Ltd. Feb. 8, 1951 [Feb. 9, 1950], No. 3336/50. Class 110(ii) [Also in Group XXIX] A differential fluid pressure motor of the oscillating-vane type such as described in Specifications 546,483 and 557,377 for actuating windscreenwipers, is provided with a valve, additional to the normal " kicker " valve gear, to allow the vane (and thus the wiper) to be parked at either end of its travel. The vane has sealing pads on each face to contact with either of two ports 21, 22, in the parked position, the un-used port being in communication with the atmosphere. The additional control valve 16 is associated with the automatic valve gear through a common, valve block 17 having the usual fluid distribution ports 8, 9, 10. A valve plate 35 is provided with slots 36, 37, 38 and may be moved laterally, Fig. 2, by means of a peg 41 which extends through a slot 42 in a cover 40, the plate being retained in position by a spring 48, the peak of which engages one of the notches 49. The valve 35 at the end of its travel, connects the suction port 9 to the appropriate side of the motor chamber 1, instead of to the automatic valve, by means of a slot 209, port 30 or 32 and one of the L-shaped ports 28, 29 communicating respectively with ports 21, 22. The second port 28 or 29, is uncovered by the valve 35 at the end of its stroke, and vented to atmosphere. The peg may be moved mechanically. It allows the wiper blade to be moved over an increased arc, e.g. when snow is on the windscreen. The slot 42 may be arranged as-' symetrically as in Fig. 8 and have only two notches 49 for the ON and " parking position and the cover 40 may be un-screwed and reversed end for end. A perforated gasket 45 is provided between the valve 35 and the block 17. A screw may be used in place of the peg 41, which may be screwed into a stop position and the slide valve may be rotary or semi-rotary and actuated through servo mechanism.

Title: Means for spacing dough pieces on conveyors
IPC: A21C9/08
Filed: 1944-02-23
Abstract: 576,286. Endless-belt conveyers. CARR & CO., Ltd., and TAYLOR, J. Feb. 23, 1944, Nos. 3413/44 and 1264/45. [Class 78 (i)] The lateral spacing of dough pieces, which are arranged to travel in parallel longitudinal series on an endless-belt conveyer, is effected by jets of gaseous fluid, e.g., compressed air. The air is supplied through a pipe 17, Fig. 2, disposed above the belt 10 to nozzles 22, 23, which are directed towards the inner edges of the outer series of dough pieces D2, D<3>. The displacement of these pieces is limited by stop pieces 24, 25. Pegs 26, 27 on a cross bar 28 disposed below the belt are arranged in the lines of separation of the series of dough pieces to form a ridge in the belt, Fig. 6. This ridging causes the separation of the overlapping edges of the pieces and facilitates their displacement. In a modification the displacement is effected as the pieces slide down an inclined plate by jets of air directed on to the underside of the pieces through depressions in the plates.

Title: Device for axial displacement of an elongated member
IPC: F42D1/10
Filed: 1961-01-30
Abstract: 972,073. Ratchet gearing. NITROGLYCERIN A.B. Jan. 30, 1961 [Jan. 29, 1960], No. 3416/61. Heading F2Q. [Also in Division E1] Ratchet mechanism for the axial displacement of a rod 28, in connection with the loading of bore holes with explosive, comprises a fixed upper clamping member 22 and a movable lower clamping member 24 which is connected with the pistons 58 of a fluid-operated actuator, the clamping members 22, 24 each comprising a housing 34 having a wall 30 of resilient material which is adapted to grip the rod 28 when fluid under pressure is supplied to a resilient annular housing 26 located within the housing 34. Control is effected automatically by a spool valve 66 and limit valves 102, 104 located at the ends of the stroke of the movable clamping member 24. The arrangement is such that whilst the rod 28 is being held by the upper clamping member 22, the lower clamping member 24 slides along the rod 28 to its lower position where it actuates the lower limit valve 104 thereby causing the lower clamping member 24 to grip the rod 28 and move it upwardly, the grip of the upper clamping member 22 being released. Upon reaching its upper position, the lower clamping member 24 actuates the upper limit valve 106 thereby causing the upper clamping member 22 to grip the rod 28 and the lower clamping member 24 to release its grip, the cycle then being repeated. By means of a pressure reducing valve 131 a reduction in the clamping power of the clamping member 24 may be effected. Also the upper clamping member 22 may be rendered inoperative by closing a valve 133 and resetting a valve 130. Under these conditions, the pipe 28 is given a downward step-by-step movement, slipping occurring during the upward movement. The pipe 28 may be brought downwards quickly by opening valve 133 and resetting valves 74 and 130. In a modification, an upper clamping member 24 is rigid with a piston 58 which is reciprocable with a housing 48 which is mounted in the wall of a bore hole 10 by a container having a resilient outer wall to which fluid under pressure is applied. The clamping member 24 carries the pipe with it during its up stroke and allows a sliding movement in the opposite direction. Specification 878,799 is referred to.

Title: Improvements in prepayment mechanism for the supply of gas, electricity or the like
IPC: G07F15/12
Filed: 1934-02-02
Abstract: 432,889. Delivery of gas &c. by time-controlled apparatus. KING, W. E., and GAS METER CO., Ltd., 238, Kingsland Road, Bethnal Green, London. Feb. 2, 1934, No. 3464. [Class 27] A coin-freed time-controlled apparatus for the supply of gas, electricity, &c., comprises a shaft c which is coupled to a setting handle by an inserted coin and which is provided with a series of actuating members in the form of double arms f, s, and u. Normally the apparatus is in the position shown in Fig. 2. As the shaft c is rotated to set the apparatus, one of the arms f engages a pin g on a lever h pivoted at j, which is raised so that a second pin k thereon is lifted clear of a slot m in a disc n turning with the main shaft o of the clockwork mechanism. Simultaneously, a spring p is brought out of locking engagement with the balance wheel r of the clockwork mechanism, the spring p being constructed so as to give the balance wheel a flick and ensure its starting. Subsequently, ratchet teeth on the end of one of the arms s engages and rotates a toothed wheel t on the main shaft o, thus winding the clockwork mechanism, and setting the disc n so that the pin k rests on its periphery (Fig. 6). Finally, an arm u engages a pin v on a lever w pivoted at x which communicates its movement to a setting arm z of the commodity control member supported in raised position against the action of a spring 7 by a pin 6 on the lever h. When the disc r returns to its original position at the expiry of the timed period, determined by the number of teeth on the member s, the pin k drops into the slot m, releasing the arm z which cuts off the supply. An additional member for cutting off the supply, operating with a second stop 10 for the balance wheel, is provided so that the supply can be stopped and resumed at the will of the customer.

Title: Improvements in transistor circuits
IPC: H03K19/082
Filed: 1962-01-31
Abstract: 982,453. Transistor logical circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 31, 1962 [Feb. 2, 1961], No. 3590/62. Heading H3T. A transistor logical circuit comprises two transistor switches 20, 21 arranged so that when an input signal of a three amplitude level input signal is applied to bases 24, 25 of the transistors both conduct, one only conducts or neither conduct in accordance with the level of the input signal and an output signal having one of three amplitude levels is obtained, means being provided to limit the potential difference between the collectors of the transistors to a predetermined value. The transistors 20, 21 are biased by supply 26 through resistors 27, 28 respectively so as to be normally non- conductive in the absence of an input signal on input terminal 5 coupled through resistor 34 and capacitor 35 to base 25 and through resistor 36 and capacitor 37 to base 24. When the input signal resides in the " 1 " voltage level, Fig. 2, both transistors conduct and the voltage at output terminal 6 approaches the voltage of ground 10, i.e. " 0 " voltage level. When the input signal is in the " 0 " voltage level both transistors are non-conducting and the voltage at the output terminal 6 approaches that of the positive supply 12, i.e. the " 1 " voltage level. When the input signal resides at the " N " voltage level transistor 21 conducts but transistor 21 is arranged so as to remain non-conducting by a suitable choice of resistors 36, 27. Hence the voltage at the point 40 approaches the level of the ground 11 and since the breakdown voltage of the Zener diode 13 is arranged to have a value equal to the voltage difference between the two levels " 0 " and " N " the voltage at the point 42 is maintained at the voltage of the " N " voltage level. The Zener diode 13 may be replaced by the series combination of a diode and a battery, Fig. 3 (not shown).

Abstract: 686,845. Titanium alloys; coating with titanium and titanium alloys. TITANGES. Feb. 14, 1950 [Feb. 15, 1949; Feb. 15, 1949; Feb. 19, 1949], No. 3791/50. Classes 82(i) and 82(ii) In a process for the manufacture of titanium alloys a titanium halide is reduced with an alkaline earth metal or a mixture of alkaline earth' metals, the reducing metal being in a divided state and in the solid condition. As shown, an evacuated reaction tube 1 containing magnesium chips 2 is fed with titanium tetrachloride from a vessel 3. On ignition of the magnesium, the titanium tetrachloride is reduced and magnesium titanide (Mg 2 Ti) and magnesium chloride are formed, the latter being collected in the liquid state in a receiver 6. When other alkaline earth metals, i.e. Ca, Ba, Sr, Be, are used the titanides formed have the general formula (alkaline earth metal) 2  Ti. The magnesium titanide may be distilled to recover the titanium or may be mixed with a metal of higher boiling point than magnesium and distilled to remove the magnesium and produce an alloy of titanium and the added metal, e.g. Cu, Al, Fe, Co, Ni and V. Articles of metal or ceramic may be coated with titanium by heating with the magnesium titanide, or by coating the article with an alkaline earth metal, reducing a titanium halide by the alkaline earth metal, and then decomposing the magnesium titanide formed by heat to produce a coating of titanium. The coating may be hardened by heating in the presence of one or more of carbon, oxygen, or nitrogen.
