Title: Machine tool
Inventor: SCRUTON ROYSTON FREDERICK
IPC: B23Q16/06
Filed: 1968-06-27
Abstract: 1,260,856. Machine tool details. GEORGE RICHARDS & CO. Ltd. 12 Sept., 1969 [27 June, 1968], No. 30820/68. Heading B3B. In a machine tool means are provided for disengaging the main drive to the shaft 7, Fig. 1, and means are provided for inching the shaft to a required.angular position. Shaft 7 is driven by a gear meshing with a gear 22, and the inching drive is from a hydraulic motor through gearing 23. In operation, the main drive is disengaged, a limit switch is actuated, and energizes a clutch 1 so as to connect the inching drive. The limit switch also operates a solenoid valve which starts motor 2, Fig. 5, and a second solenoid valve which causes a probe 3 Fig. 4, to engage a cam surface of shaft 7, and causes a cylinder 4 Fig. 3, to be charged with energy absorbing fluid. Shaft 7 is inched around by motor 2 until a projection 6 on the cam operates probe 3, which operates a limit switch LS1 Fig. 4. This energizes a solenoid valve which causes a hydraulic actuator 8 Fig. 3, to pivot a stop 5 into engagement with a recess in the cam, and a limit switch LS2 is actuated to de-energize clutch 1, and the solenoid valve, so that motor 2 stops. Any further rotation of shaft 7 is absorbed by movement of stop 5 to compress the fluid in cylinder 4, which latter moves the shaft back to the correct angular position. Hydraulic actuators 11, 13 and limit switches LS4-LS7 Fig. 1 provide for automatic programme changes of tool 21 in the manner described in United King- dom Specification 1,142,322.

Filed: 1935-11-11
Abstract: 463,086. Feeding articles from hoppers. ARMSTRONG CORK CO. Nov. 11, 1935, No. 31181. Convention date, Jan. 29. [Class 78 (i)] A centrifugal feeder for discs and the like comprises a conveying ring which is fed centrifugally by a rotating member to which the discs are delivered promiscuously, means being provided for preventing superposed discs from entering the ring and means engaging the discs on the ring to remove them therefrom at the desired delivery point. In the form shown, the discs tipped promiscuously into the hopper 60 are delivered by the pocketed wheel 61 past the spring shutter 63 for preventing superposition of discs in any one pocket, into a conduit 62 in which they are blown by compressed air into a chamber having a rotary plate 2. The latter delivers them centrifugally underneath a fixed peripheral guard plate 23 on to a slower-moving ring 14, which delivers through the downwardly-curved shoot 24, Figs. 1 and 5, from which they fall by gravity into the stacking-tube 39. The guard 23 prevents superposition on the ring 14 and also prevents outward movement beyond the edge of the latter. To prevent the discs moving inwards again after having reached the ring 14, the latter may be set slightly below the plate 2 or a plate 27, Fig. 6, may be set to confine them prior to arriving at the point at which they pass tangentially into the shoot. To prevent a jammed disc partly under the guard 23 but unable to reach the periphery of the ring 14 from fouling the entrance to the shoot, a rapidly-revolving shaft 34, with squared lower end contacts with it and impels it back on to the ring 14. The tube 39 is oscillated rapidly through a small angle in a horizontal direction by a bell-crank 46 and gearing 42, 43 to shake the gravity-fed discs into a horizontal position to form a pile or stack ready for feeding a machine. Preferably the rate of feed from the shoot will be greater than the rate of feed from the tube 39 so that the latter will be kept filled; surplus discs falling into the hopper 41 for return to the initial hopper 60. When the pile of discs in the tube 39 falls below a predetermined level, a weighted arm 50 penetrates a slot in the wall and, in so doing, actuates a cut-out for the drive of the using machine or makes some kind of signal, Variation of the speed of the ring 14 will then adjust the rate of delivery as may be necessary.

Abstract: 965,504. Hydraulic servomotor assisted brakes. BENDIX CORPORATION. Aug. 14, 1962 [Sept. 1, 1961], No. 31213/62. Heading F2F. A fluid pressure servomotor has an axially extending fluid pressure chamber having a driven movable front end wall 32 and a movable rear end wall 36, the rearward movement of the rear wall 36 being limited by stop means 38, a control valve comprising an axially movable control member 84, 86 having a normal position (as shown) in which the valve communicates the chamber with an exhaust port 100 through passages 94, 96, 98 and 102 and being movable in a forward direction to close communication with the exhaust port and communicate the chamber with a pressure port 58 through valve 70 and passage 68, abutment means 93 for transferring forward motion of the member 86 to the rear wall after the chamber is communicated with the pressure port 58, and a check valve 118 preventing return flow out of the chamber through the pressure port, whereby forward movement of the rear wall driven by the member 86 drives the front wall 32 through the intermediary of the fluid trapped between the walls. As shown, hydraulic pressure from an accumulator 110 charged by a pump 106 through a check valve 108, a relief valve 112 being provided, is admitted to the chamber 54 on actuation of the brake pedal 24 to move the control members 86, 84 forwardly to unseat ball 70. The hydraulic pressure in chamber 54 acts through passage 56 in the piston 36 on the piston 32 to move it forwardly to actuate the brakes A by means of the master cylinder B. A reaction force on the member 86 which moves the latter rearwardly is provided by a rubber block 126 held on the member 84 and forced by the pressure in chamber 54 against the end of the member 86. If there is a partial failure of the hydraulic pressure from the accumulator 110 actuation of the brake pedal 24 will result in the member 86 moving the piston 36 through the horseshoe washer 93 held in a groove in the piston 36. The check valve 118 will prevent any fluid returning to the accumulator through the open ball valve 70 so that the piston 32 is moved through the intermediary of the fluid trapped between the two pistons. Total failure of pressure will result, on actuation of the pedal 24, in the pistons 36, 32 abutting to thereby operate the brakes.

Patent GB-869959-A (GB)
Title: Production of dicyclohexyl phthalate
IPC: C07C69/80
Filed: 1958-10-07
Abstract: Dicyclohexyl phthalate is produced by heating a mixture of phthalic acid and/or phthalic anhydride and a stoichiometric excess of cyclohexanol in the presence of an acid dehydrating-catalyst, at a pressure not exceeding atmospheric pressure, the temperature of the reaction-mixture being at least sufficient to vaporize the cyclohexanol/water azeotrope, passing the vapours, which contain cyclohexene (formed by decomposition of cyclohexanol), to a cooling-zone where in the cyclohexanol is condensed but cyclohexene (and its water-azeotrope) remains in the vapour phase, and removing cyclohexene from the system.  The following catalysts may be used:- sulphuric acid, p-toluene p  sulphonic acid, the alkane sulphonic acids, and the sulphamic acids.  In an example, a mixture of phthalic anhydride, cyclohexanol and sulphuric acid is heated at a temperature of 117 DEG -125 DEG C. and an absolute pressure of 170-220 mm.; and the vapours are passed to a fractionating column, the head of which is maintained at a temperature between 55 DEG  and 75 DEG C.  The uncondensed vapours, consisting chiefly of cyclohexene and water, are withdrawn overhead, while the condensate, consisting chiefly of cyclohexanol, is returned to the reaction-mixture. The cooled product is washed with aqueous sodium hydroxide followed by water, and then subjected to steam-distillation to remove volatile material.  The dicyclohexyl phthalate so obtained is dried; and a crystalline almost-colourless product is obtained.
