Title: Cable stowage device
IPC: B65H75/42
Filed: 1967-07-06
Abstract: 1,135,145. Cable reels. WOLF G.m.b.H. 6 July, 1967 [8 July, 1966; 9 March, 1967; 27 April, 1967], No. 31253/67. Heading B8M. [Also in Division A1] A cable storage device comprises a rotatable cable reel 3 for cable 4 supplying power e.g. to a lawn mower 5, and a tensioning motor 9 drivingly connected to the reel and permanently connected electrically to the cable, the tensioning motor 9 applying a driving torque to the reel to wind the cable on to the reel when power is supplied to the cable. The motor 9 preferably drives a pinion 18 meshing with an internal ring gear 17 on the reel. The torque applied by the motor 9 may be variable by means of capacitances selectively connected by a limit micro-switch operable by rotation of one reel so that a greater torque is applied in one rotation direction than in the other. The cable reel may be mounted directly on an electrically driven lawn mower or may be located at a point remote from the lawn mower. When the reel is mounted on the lawn mower, a guide arm for the cable is provided to prevent severing of the cable by the rotary cutter.

Title: Process for treating polymers of olefins and di-olefins
Inventor: DOST NICOLAAS
IPC: C08F4/64
Filed: 1955-11-01
Abstract: Catalyst remnants are removed from a polymer slurry obtained in the low-pressure polymerization of polymerizable olefins and diolefins by adding to the polymer slurry a substance capable of converting the catalyst remnants present in the polymer slurry into a product which is insoluble at elevated temperatures in the solvent used for the polymerization reaction, whereupon the hot polymer solution is freed from the insolubilized catalyst remnants.  Specified polymers are those of ethylene, propylene, butylene and butadiene.  Specified insolubilizing materials are alkali metal and alkali earth metal hydroxides or carbonates, e.g. calcium hydroxide, terrana, and fuller's earth.  The temperature of the insolubilization reaction may be from 100-250 DEG  C. while the hot polymer solution after being freed from the insolubilized catalyst remnants may be evaporated with the aid of a film evaporator.  Specifications 799,392, 799,823 and 801,031 are referred to.

Title: Improvements in or relating to presses
IPC: B30B1/23
Filed: 1952-12-10
Abstract: 731,187. Screw presses &c. SCHULER AKT.-GES., L. Dec. 10, 1952 [Dec. 12, 1951], No. 31294/52. Class 87 (2). Relates to screw drawing presses of the kind comprising a screw moving a drawing ram wherein a flywheel is mounted on the screw and consists in the interposition of a torque-transmitting fluid coupling between the driving motor and the driven part, preferably the screw. A housing 4, 17 incorporating blades 19, forms the driving member of the fluid coupling, being secured to the shaft 22 of the motor 3 and freely rotatable on the shaft of the screw 6, Fig. 1. The driven member 5 is fixed to the screw 6 and incorporates blades 21. A hydraulic brake comprises a pressure cylinder 11 with a piston 10 which carries a pressure plate 15 with a brake lining 14. When the press ram 8 reaches its upper position, as shown, a stop 23 thereon strikes a piston 24 of a hydraulic pressure cylinder 25 and causes pressure fluid to be forced into the cylinder 11, with the result that the plate 15 is pressed against the riin of a flywheel 7 keyed on the screw 6. This braking action can be adjusted by varying the capacity of an air cushion above the piston 24. A reduction gear may be fitted between the fluid coupling and the screw, Fig. 2, with a friction clutch to protect it against rebound impacts. The clutch comprises a plate 31, with teeth 29 on its periphery, between two plates 32, 33. The plate 31 is geared to a pinion 45 on the driven shaft of the fluid coupling and the plates 32, 33 are rotatable with the screw 6 and slidable on it under the pressure of a spring 35. When the ram 8 reaches its bottom position a bar 41 thereon operates a reversing switch 38 and when it reaches its upper position a bar 41<1> operates a switch 39 to switch off the motor, which is of the sliding armature type incorporating a brake which operates when the current is switched off. Safety hand levers 43, 44 must be held down while the switch is operating; if released, the drive is reversed.

Abstract: 895,877. Distilling oil shale; charging and discharging retorts. UNION OIL CO. OF CALIFORNIA. Sept. 12, 1960, No. 31331/60. Classes 51 (1) and 55 (2). Oil shale is fed from hopper 21 into a feeder cylinder 18, which may be oscillated about trunnion 20, by means of hydraulic cylinder 24, from a position below hopper 21 to the position shown where it is below a disengaging section 12, so that oil shale is continuously fed upwards through the disengaging section 12, and kiln 10 where the shale in a first zone is preheated and the educted liquids and gases are cooled and in a second zone the preheated shale is retorted by means of a hot eduction gas flowing downwardly. The eduction gas and liquid and gaseous products flow downwardly through the shale preheating zone of kiln 10 and pass through apertures 62 of disengaging zone 12 into a separating zone 60 from which most of the liquid products are removed through line 74, a small amount being recycled through line 61 and pump 72 to the feeder housing 14 so that a slurry of oil and fines may be returned from housing 14 through line 27 to the settler 60. The shale ash is displaced by rotating rakes 58 and falls via a casing 26 into a cooling zone 34. The gas removed from settler 60 through line 76 by blower 78 is freed from mist at 80 and divided into five portions, one of which is removed from the process at 116. Another portion passes through line 91 to be combusted in an indirect air preheater 93 with some of the air which has been preheated and returned through line 99. The main volume of air entering preheater 93 through line 98 passes into a burner where it burns another portion of the gas from line 76, the resultant gases at a temperature of 1500‹ to 2500‹ F. being mixed with another portion of the gas from line 76 produce a gas stream entering kiln 10 through line 44 at a temperature of 900‹ to 1800‹ F. The last portion of gas from line 76 flows through ring manifold 46 and shale ash cooling zone 34 to the top of kiln 10.
