Title: An anti-spin device for a motor vehicle
IPC: B60T8/48
Filed: 1969-11-10
Abstract: 1291889 Aritispin systems NISSAN MOTOR CO Ltd 10 Nov 1969 [12 Nov 1968 10 Dec 1968] 54878/69 Heading F2F A device for preventing spinning of a vehicle's driving wheels used in combination with either an hydraulic or pneumatic braking system comprises a spin detector delivering a voltage when a difference in speeds of the right and left driving wheels is detected to means which delivers fluid pressure to the wheel cylinders of the spinning wheel. In the embodiment shown in Fig. 1 hydraulic pressure passes from a master cylinder 2 directly to the front wheel cylinders 3, 3<SP>1</SP> and to the rear wheel cylinders 4, 4<SP>1</SP> by way of auxiliary cylinders 10, 10<SP>1</SP>, through conduit 14, inlet port 12, outlet port 13 and conduit 15. Spin is detected by sensors 55, 56, Fig. 3a (not shown), on the driving wheels which convert the wheel speeds into pulses fed to pulse shapers (57), (58) to give the pulses predetermined widths, the pulses being integrated by speed detectors (59), (60). The speed detectors are connected with a speed difference detector (61) which when it detects a voltage difference in excess of a predetermined reference delivers an output voltage to either of two Schmidt triggers (62), (63) each associated with one cylinder 10, 10<SP>1</SP> to pass a voltage to either of gate circuits (64), (65) and power amplifiers (66), (67). Auxiliary cylinders 10, 10<SP>1</SP> have pistons 22 actuated through a member 20 by a plunger 16 carried by a diaphragm 28 separating respectively air and vacuum chambers 27, 26 which in normal brake operation are connected via conduits 33, 34, chamber 35, port 45 and conduit 49 to the engine intake manifold 5. When either amplifier transmits a signal to a solenoid valve 32 or 32<SP>1</SP> associated with the spinning wheel a plunger 40 moves to close chamber 26 from chamber 27 by means of a valve member 38, air passing through a filter 47, conduit 46, port 45, past a spring- loaded valve member 45, through a hole in partition wall 37, and via conduit 34 to chamber 27 to move the diaphragm 28 and associated plunger to pass hydraulic fluid to either wheel cylinder 4 or 4<SP>1</SP>. In a modification, chambers 27 26 are supplied with compressed air, valve member 38 closing chamber 26 from communication with the supply to move diaphragm 28 when either solenoid valve is energized. In the embodiment in which the brakes are actuated by a conventional compressed air system the solenoid valve actuates a valve member by way of a plunger to directly supply the brake chamber with compressed air. An additional sensor (68) may be provided to monitor the speed of either undriven wheel so that if either sensor (55) or (56) fails the solenoids 32, 321 are not actuated unless the wheel speed detected by either sensor (55) or (56) exceeds that of the free wheel detected by sensor (68) by a predetermined amount.

Title: Attachment device to attach an implement to a lifting  linkage of a vehicle
IPC: A01D67/00
Filed: 1972-12-07
Abstract: 1390948 Attachment device for vehicle lifting linkage WILHELM STOLL MASCHINENFABRIK GmbH 7 Dec 1972 [7 Dec 1971] 56619/72 Heading A1P A device for connecting an implement to the three point lifting linkage of a vehicle is characterised in providing an articulated connection when the implement is in the working position and locking it against rotation about a vertical axis when in the transport position. It has a first part connected to the implements and a second part attached to the vehicle, the two parts being connected by a vertical first axis 19, and a horizontal second axis 18. The second part comprises a lower cross member 12 supported by pivot shafts 10, 11 inserted in the vehicle lower link bearings and the first part an upper framework 1, attached pivotably at its upper end to the vehicle upper link and to a pivoted connection 19 in the lower member 12. In the working position shown in Fig. 1, the implement 3 attached to the upper framework can slew within the limits set by the plates 25 which act as stops to the beam 15. When the implement is lifted into the transport position by raising the lower links the beam 15 is caused to rotate about the second axis 18 and to close against a spring the gap between the beam 15 and the segments 23 until the cylinders 20 attached to the beam latch into two of the notches 22 of the segments. Further upward movement of the lower links then causes the implement to be lifted. This gravity lock can be made positive by means of a peg carried on a rotating and sliding arm on the upper framework 1 which can be engaged (and pinned) in a hole in the lower part 12. In one embodiment, the second axis 18 is in the form of a rubber bush which also provides the separating torque between the cylinder 20 and the notches 22 and in addition some freedom about a fore and aft axis between the upper framework 1 and the lower member 12. The torque provided by the rubber bush can be preset to suit the weight of the implement by means of a rotary slotted adjustment between the straps 16, 17 and the two torque arms attached to the inner part of the rubber bush.

A method for eliminating the impurities formed by radiolysis in CO 2  gas, used as coolant in a graphite-moderated nuclear reactor and to which a small proportion of methane has been added to inhibit the reaction between the CO 2  gas and the graphite, comprises the conversion of H 2 O into H 2  by the action of CO on H 2 O, and the conversion of H 2  into CH 4  by the action of CO or CO 2  gas on H 2 . The first conversion may be effected by passing a portion of the reactor coolant through a catalyst having a basis of Cu and Zn at a temperature between 170‹ and 200‹ C., and the second conversion using a catalyst having a basis of Ni, Co or Ru at a temperature of 250‹ C. The two conversions may be repeated alternately several times in different catalytic reactors. Alternatively, a single catalytic reactor may be used in which catalysts for both conversions are either mixed or disposed in alternate beds, or a single catalyst for both conversions may be used. The methane content of the coolant is controlled by the introduction or withdrawal of either water or hydrogen.

Abstract: 782,253. Calculating-apparatus. BURROUGHS CORPORATION. March 2, 1956 [March 4, 1955], No. 6690/56. Class 106 (1). In an accounting machine having a paper carriage bearing control projections of various lengths which are sensed by control means to determine the nature of the machine operation, additional control means may be selectively operated to arrest certain of the sensing means before they engage the corresponding control projections effective at any time so as to modify the set programme. As described, an overriding control is exercised on four of the sensing pins or tappets of the machine described in Specification 709,181 by means of solenoids which may be remotely controlled. In that machine, control projections 27 of various lengths are sensed by the tappets 17 which are pivoted on the ends of levers 18. To effect sensing, cams move the centre parts of the levers 18 upwardly and when a tappet 17 abuts the corresponding projection 27, the other end of its lever 18 is moved upwardly to rock a control lever. The extent of movement of the latter depends on the length of the projection 27. Four of the tappets 17 are now formed with ears 78 which co-operate with feet 58 of respective pendants 48 pivoted on a rod 43. Two of the pendants 48 are respectively coupled by links 60 to the armatures of solenoids 72 while the other two are integral and are coupled by a single link 60 to a further solenoid. Normally the feet 58 are out of the paths of the ears 78 but when a solenoid 72 is energized, the corresponding foot 58 is pushed over the ear 78 of the associated tappet 17 which is thus held in a lowermost position during the sensing operation although the aligned control projection 27 may be a short one. A spring coupling between each foot 58 and its pendant 48 allows the foot to be cammed aside if it should be moved beneath the ear 78 when the latter is in raised position.
