IPC: B66F9/075
Filed: 1972-07-04
Abstract: 1341540 Vehicle protective roof STEINBOCK GmbH 4 July 1972 [5 July 1971 22 Sept 1971 3 Nov 1971] 31267/72 Heading B7B A roof for protecting a vehicle, e.g. a fork lift truck against falling objects is displaceable without deformation to reduce the risk of the roof injuring the driver having jumped or been thrown out in a roll-over accident. In one embodiment (Fig. 2) the roof comprises cylindrical bars 18 slidable in bores in a beam 16 which extends longitudinally above the driver's seat. Plates 19 carrying padding 20 are provided at the ends of bars 18 which are held against rotation by a peg-and-slot and are normally held in a central position by friction fit and/or a spring detent. The slidable roof bars may extend on one side only of the central beam 216 in staggered formation and be urged towards retraction by a spring 221 (Fig. 147 against a stop formed by slidable pin 228 in bore 227. When the vehicle tips over and padded end 220 strikes an object (e.g. the driver) the cam surface 232 at the inner end of rod 222 lifts the pin 228 allowing the spring 221 to retract the roof bar to avoid injury. In another embodiment (Fig. 9) the roof comprises two fixed cross-bars 118, 119 upon which two side-bars 120, 121 are slidably mounted. Between each of the bars 120, 121 and the fixed central bar 115 are links 122 which are hinged so that they resist falling weights but allow side-bars 120, 121 to move inwardly when striking an object after rolling over. The links 122 may be replaced by a flexible nylon net. In a further embodiment (Fig. 17) the roof comprises frames 246, 247 which are pivotable about longitudinal struts 248, 249 and to which are rigidly attached pendulums 251, 252 one of which pivots a roof frame inwardly (broken lines) in the event of a roll-over. A single independently pivoted pendulum may be used having arms or links to operate either roof frame. A single roof frame 280 (Fig. 28) may be pivoted at one side of the vehicle, the pendulum 284 being separately pivoted and operating the roof frame by a link 285.

Title: Improvements in and relating to the production of tools comprising diamond
IPC: B24D3/08
Filed: 1936-11-16
Abstract: The operative portion of abrasive, cutting, &c. tools is made by pressing into a coherent mass a mixture of diamond particles and in powder form one or more of the metals copper, nickel, cobalt or aluminium or alloys having a basis of these metals or the ingredients of such alloys.  Alloys referred to are inter alia silicon bronzes, age hardening copper base alloys, brasses and bronzes containing 70-80 per cent zinc, and bronzes containing 10-20 per cent tin.  The mix may contain up to 60 per cent diamond particles according to the fineness thereof, and the particles may be graded.  The production of the coherent mass may be assisted by the application of heat, but the heat should not be sufficient to fuse the metal bond; by employing non-oxidizing conditions; and by adding non-metallic materials, e.g. a sulphide, which will promote coalescence of the metal particles under pressure and the adherence thereof to the diamond particles. The non-operative portion of the tool may be formed from finely divided metal from which diamond is omitted.

Title: Improvements relating to polymerisation process
Inventor: GINTZ FRANCIS PAUL
IPC: C08F36/18
Filed: 1964-08-05
Abstract: Chloroprene is polymerized to give a latex of cross-linked polymer and chloroprene polymerized in this latex under non-cross-linking conditions caused by the presence of sufficient chain transfer agent to give a final chloroprene polymer containing a minimum of 10% and a maximum of 60% of the cross-linked polymer. A minor amount of a comonomer may be present in the copolymer while by cross-linked polymer is meant one not forming a true solution in benzene at 20 DEG C.  It is preferred that the monomer be added continuously while cross-linking polymerization occurs and the initiator concentration adjusted to give by the time the first 20% monomer has been added a ratio of polymer to monomer of at least 1.5 to 1 and a ratio of at least 4 to 1 at the end of the cross-linking step.  The usual chain transfer agents alkyl mercaptans (especially n-dodecyl mercaptan), dialkylxanthogen disulphides, iodoform, benzyl iodide are used.

Abstract: 996,283. Gyroscopic apparatus. GUIDANCE TECHNOLOGY Inc. Sept. 5, 1961 [Sept. 16, 1960], No. 31909/61. Heading G1C. [Also in Divisions B7 and H2] A gyroscope, such as a gyrovertical, has its outer gimbal 21, Fig. 16 supported by a shaft 25 mounted in bearings 28, 29, in a movable support 30, itself mounted in bearings 32, 33 in a projection 31 fixed to the casing 11, the support 30 being oscillated to reduce bearing and slip ring friction, by a constant speed motor 199, gears such as 198, 196 and crank arm 194, the shaft 25 having slip rings 173 co-operating with wipers 172 on slip rings 169 provided with wipers mounted on an insulated support which is rigid with the frame projection 31. As shown the gyrovertical comprises a rotor case 40, Fig. 8 supporting a rotor which is in two parts 72, 85 so that it is pendulous when starting. On starting the rotor, balls 98 move outwardly under centrifugal force and act on cam surface 95 on ring 94 to force portion 85 upwardly against the action of springs 102 to bring the rotor into neutral equilibrium. The rotor has impellers 75 which force gas through openings 105 and discharge it through passage 106, 107 and slots such as 111, 113 controlled by pendulous shutters 117 to provide erection, the circulation of the gas also helping to cool the rotor motor and bearings and circulate the heat around the casing 11. The attitude of the gyrovertical is communicated by reverse gearing giving an amplified movement, to an indicating sphere 133, Fig. 2, mounted in the same outer gimbal as the gyrovertical and observed through a glass window 16 provided with markings 18, 20, Fig. 1. The translucent plastic sphere 133 is illuminated by a plurality of lights supported by an insulated plate 148, and a diffusing lens 149. When the gyroscope is unenergized a flag 221 appears in window 16 but on current being supplied to the rotor motor, a solenoid 225 is energized, after a time delay introduced by a circuit in the solenoid winding, and this rotates a rod 214 against spring action to move flag 221 behind a shield and remove a shoe 211 from caging engagement with a rim 210 on the outer gimbal. Specification 927,112 is referred to.

Title: Improvements in and relating to cup dispensing mechanisms
Inventor: NUNN GEORGE WILLIAM
IPC: B65G59/10
Filed: 1961-09-06
Abstract: 1,014,491. Dispensing cups. GLOSTER EQUIPMENT Ltd. Sept. 5, 1962 [Sept. 6, 1961], No. 31992/61. Heading B8S. Cups are dispensed singly from the bottom of a stack through aperture 2 by a device which includes pivoted arms 27, 28 and sliders 14, 15. The arms 27, 28 are pivoted at 9 and 10, and sliders 14, 15 carry stripper cams 37. The device is operated by the movement of link 33 about pivot 34 by means of driving arm 35. Link 33 is connected to sliders 14 and 15 by studs 21 and 23 carried by the sliders so that clockwise movement of link 33 (Fig. 2) causes slider 14 to move rightwards and slider 15 to move leftwards. The rectilinear movement of sliders 14 and 15 effects two actions. Firstly, the stripper cams 36 and 27 engage between the lowermost cup and the next lowermost cup to separate the two cups. Secondly, pivoted arms 27 and 28 are caused to pivot outwardly about pivots 9 and 10 by the engagement therewith of studs 22 and 24 carried by the sliders. In this way the lowermost cup is separated from the stack and the outward movement of arms 27 and 28 permits the separated cup to fall and be discharged. The link arm 33 is then moved anticlockwise to its initial position. This brings back into original position both the sliders 14, 15 and arms 27, 28 so that the stripper cams 36, 37 are removed from the stack which is then supported by the arms 27, 28 now in their inner position. Thus each oscillation of link 33 effects the discharge of a cup from the stack through aperture 2.
