Abstract: 576,528. Lift cages. EXPRESS LIFT CO., Ltd., and DIXIE, W. A. Jan. 31, 1944, No. 1788. [Class 78 (iii)] [Also in Group XXXVII] Driving apparatus for a lift or the like comprises a main motor with a shaft connected thereto carrying a multi-vee belt pulley adapted to drive the hoisting sheave of the lift through a multi-vee belt drive, and an auxiliary motor connected through a mechanical clutch with said shaft and arranged, when the clutch is engaged, to drive the shaft at a lower speed than that at which it is driven by the main motor. In the embodiment shown, the hoisting sheave of the lift is normally driven by the electric motor 2 through multi-vee belting connected to a pulley 4. When the lift is to be driven at " levelling speed " a pulley 10 connected by belting 9 to the auxiliary motor 6 is moved axially against spring means into engagement with a friction disc 15 on the pulley 4, and the power supply to the motor 2 cut off, the armature on the shaft 3 serving as a fly wheel. The pulley 10 is moved axially through a lever 16 pivoted at 17 on the frame 5 and adapted to engage a crosshead 18 connected by a pair of rods to a member 20 which has a ball thrust bearing connection with the boss of the pulley 10. The lever is held in its inoperative position by the core 27 of a solenoid 25, but is moved to its operative position by spring 16 on de-energization of the solenoid coil 26 which is effected bv movement of the cage switch to " levelling" position. The various control devices may be supplied with current by a small D.C. generator driven through belting by a pulley 30. Lubricant in a receptacle 23 is distributed through channels in the shaft.

Title: Improvements in machines for moulding shoe heel stiffeners
IPC: A43D8/04
Filed: 1946-01-21
Abstract: 606,843. Moulding shoe - stiffeners. CHAMBERLAIN, W. H. Jan. 21. 1946, No. 1954. [Class 17(i)] A Stewart type machine for moulding heel stiffeners is provided with a presenter or carrier device 29, such as that described in Specification 482,761, for presenting a blank to the mould and is arranged so as to be started on each cycle of its operation by movement of a handle 151 arranged to one side of the wiper guides, so that, after removal of a moulded stiffener from the centre piece of the mould at the end of a cycle of operations, the operator may restart the machine on a further cycle using the same hand as for removal of the stiffener, safety and output both being thereby increased, since the hand is drawn clear from the mould before the door descends. The jaws of the carrier remain open when the carrier falls away, after presenting the blank, and close automatically upon a newly inserted blank so the carrier is moved towards the mould. The carrier jaws may also be opened independently by a hand lever 116. The machine illustrated is similar in many respects to that described in Specification 482,761 but starting is controlled by a hand lever 150, having a handle 151, pivoted on the right hand side of the machine head and the rear end of which operates a rocking lever 85 by which a stop 87 for a cam driving shaft 66 and a clutch fork 78 of a countershaft 68 are controlled in the same way as the pedal controlled starting in the machine of the earlier Specification. Rotation of the cam shaft 66 causes a cam 65 to tilt the rear end of an arm 63 to turn a rock shaft 54 and the carrier 29 mounted thereon to present a blank placed between the open jaws 32 thereof to the mould. The handle 151 when released is raised towards its initial position by a spring 149 and returns to it when the cam shaft 66 has completed its revolution. The jaws 32 are positively opened against the action of a spring 50 by fingers 107 descending in advance of the door of the mould and are kept open in the lowermost position of the carrier by a spreader acting through the handle 116 to permit the insertion of another blank. These jaws may also be opened under manual control of the handle 116 through a flexible cable 137, and close automatically on a newly inserted blank as the carrier is moved up towards the mould, When moulding stiffeners with a drop waist provision is made for an increased stroke of the door or wiper of the mould by providing a spring buffer device on the rod 21 which controls the door, or by varying the stroke of the connecting rod which operates it.

Abstract: 1,205,004. Fuel cell. UNITED AIRCRAFT CORP. 14 Jan., 1969 [12 Feb., 1968], No. 2098/69. Heading H1B. In a fuel cell, of the H 2 /O 2 -KOH type, employing permeable electrodes 10, 12 and having a concentration gradient of OH- ions, carbon containing substances are removed from the alkaline electrolyte 14a by promoting the generation of gaseous carbon-dioxide from CO 3 <SP>2-</SP> and HCO 3 - by disposing a diffusion barrier 40, of for example porous nickel or asbestos, adjacent the anode 10 to provide a mild impedance to the imigration of ions toward and away from anode 10 which allows a OH- ion concentration gradient to exist and permits a lower concentration of OH- at the liquid interface 30 in the anode. Thus the pH in the liquid side of the interface can be lowered to 8 or 9 thus promoting the reaction The diffusion barrier also slows the migration of CO 3 <SP>2-</SP> and HCO 8 - ions away from anode 10 thus promoting the reaction The diffusion barrier 40 also impedes the diffusion of CO 2  into the bulk of electrolyte 14a, thus allowing the build-up of sufficient pressure of the molecules to diffuse through the anode and be carried away in the gaseous effluent through duct 22.
