Title: Refrigerating apparatus based upon the use of air
IPC: F25B9/00
Filed: 1923-04-12
Abstract: 197,311. Soc. Anon. pour l'Exploitation des ProcÚdÚs M. Leblanc- Vickers. May 8, 1922, [Convention date]. Addition to 170,557. Refrigerating, cold - air machines and processes for. -The machine described in the parent Specification is modified by arranging gearing so that the head of the connecting-rod of the piston of the " powerless " compressor traverses an epicycloid about the driving shaft, thereby increasing the length of time during which the valves remain open and the independent fans are effecting the exchange of air between the cylinder of the " powerless " compressor and the cooler and refrigerator. A further modification consists in replacing the plate valves by slide valves arranged in the " powerless " piston and cylinder, the valves being thereby actuated directly from movements of the piston, instead of through cams and links as in the prior construction. Two forms of gearing are described, one, Figs. 5, 8, and 11, comprising stationary gear wheels A surrounding the shaft O driven through reduction gearing H, D from an electric motor, with the head of the connecting- rod E connected eccentrically to pinions B rolling on the gear wheels A. The other form, Fig. 9, comprises internally toothed stationary gear wheels A<1> with the head of the connecting-rod connected eccentrically to pinions B<1> secured to crank arms K on the driving shaft O the crank arms carrying also rolling pinions S mounted between the pinions B<1> and the stationary gear wheel. The arrangement of the valves is shown in Fig. 2, in which the " powerless " compressor comprises two cylinders, with ports 6 communicating with the cooler R<1> and ports 5 communicating with the refrigerator R<2>. Communication between these ports and the ends of the piston cylinders is established by passages 8 arranged in the piston 2. The independent circulating fans are shown at W, Fig. 2. In another construction that embodies these modifications, the " powerless " compressor is constructed in such a way as to render the ordinary compressor C unnecessary, as in one of the constructions according to the parent Specification.

Title: Improvements in and connected with the control of electric light circuits
IPC: H01H3/58
Filed: 1935-04-01
Abstract: 454,625. Stencil switches; electromagnetic switches. APPLEFORD, J. F., St. Martin's Theatre, West Street, St. Martin's Lane, London. April 1, 1935, No. 10125. [Class 38 (v)] In apparatus for controlling the lighting of theatres, a perforated record (not shown) that is passed between a series of contacts 26 and a series of contacts 27 allows selected circuits only to be closed to the lamps or to the contactors which control the lamps. The record is moved on step-by-step allowing a different combination of lamps to be illuminated at each step. In the form shown, the record consists of an insulating web, Fig. 7, which is wound step-by-step from a storage drum 4 on to a drum 5 by the manual reciprocation of a lever 16, Fig. 3, which by means of a pawl 19 drives a ratchet-wheel 20 geared to the drum 5. Each contact 26 is connected to the winding of a contactor corresponding to a particular lamp and co-operates with four spring-plunger contacts 27, all of the groups of contacts 27 being connected to a common bus-bar. The purpose of having four contacts 27 is to enable the lowest of them to make contact through a succeeding perforation before the upper has broken contact and so prevent a lamp from going out in passing from one step to the next when it is desired that the lamp should remain lit for the two steps. The perforations in the web may conveniently be made by pressing down selected levers 54 attached to cams 52 which actuate punches 48. Electromagnetic switches.-The contactor switches may each take the form shown in Fig. 8 wherein closure of the circuit 33, 34 including the contacts 41, 42 causes the attraction of a plunger 36 and the closure of main and auxiliary contacts 37, 38 and 39, 40 and then the opening of contacts 41, 42, a spring 45 allowing the extra movement of the plunger. The opening of the contacts 41, 42 removes the short circuit from a resistance 43 which then serves to keep the current flowing in the contactor winding to a suitable low value.

[Class 100 (i)] Relates to sheet-feeding apparatus such as is described in Specifications 561,072 and 561,080 divided therefrom in which sheets or flat articles are fed from a pile and advanced to printing or other machines by means of perforated or pervious belts 360, Fig. 1, or 367, Fig. 2, passing over surfaces connected to exhaust apparatus which causes the leading edges, Fig. 1, or the rear edges, Fig. 2, of separated sheets &c. to be attracted to the belts so that these edges are continuously held to the belts by suction. According to the present invention, the sheets &c. are adapted to be advanced in overlapped condition. The sheets are separated from a pile 361 by means of suction separators 364 acting on the rear edges of the sheets, assisted by air blasts from a pipe 365, and in Fig. 2 the rear edges of the sheets are held by suction apertures arranged above the lower run of a conveyer belt 367, the forward edges being held by a plain conveyer belt 360.

Abstract: 108,188. Walker, J. H. July 25, 1916. Runways; trollies for runways; transferring by hauling and paying-out between elevated supports.-In lifting or hauling gear for loading and unloading ships, of the kind in which hoisting and slueing ropes c', d<1>, are provided, a cableway e is arranged between the ship and the quay, and the ship end of the cableway is secured in such a position relative to the lifting and slueing derricks c, d that goods lifted by the lifting-derrick can be slued to a position adjacent the cableway and attached to a traveller h thereon without depositing them upon the ship's deck. One end of the cableway e is fixed to a support g on the quay and the other end is passed over a sheave g on sheer legs f and connected to a winch on the deck a. The carrier h, Fig. 3, comprises two wheels h<0> mounted between bars h<1>, h<2> which are connected by parallel bars h<3>, h<4>, A hook h<5> supports the goods, and a rope i connected to a winch controls the movement of the carrier. In a modification, the cableway comprises a rope e, Fig. 5, on which the traveller runs, a combined hauling and return hauling rope i', i<2>, and a hoisting rope i<3>. The return hauling portion i<2> of the combined rope is connected to one end of the carrier, and after passing round sheaves k, l, l<1>, l<2>, the rope is wound for a few turns round the drum m of a double drum capstan, and then led round a pulley n and the hauling portion i<1> connected to the other end of the carrier. The hoisting rope i<3> is passed over a pulley o and connected to the other drum o' of the capstan, these drums being arranged so that they can be worked together when a clutch is thrown in to coil or uncoil the two ropes at the same rate. In order to prevent too great a strain on the cable-way if the ship lurches, or when the draught alters, the rope e is passed round a pulley e<3> and connected to the axle of the pulley l<1>, this axle being connected also to one end of a rope q. The other end of the rope q is attached to a winch s and the rope is passed round a series of purchase pulleys q<1>, a series of purchase pulleys on the axle of the pulley l<1>, and pulleys q<2>, q<3>, r<2>, one of which carries a balance weight r. The purchase pulleys and the pulleys e<3>, l, l<2>, n, o can be mounted on a pivoted king-post. In another modification, the sheer legs f are dispensed with and the cableway is supported by a block attached to the head of the slueing-derrick. In a further modification, the cableway is dispensed with and the carrier runs on the slueing-rope and is attached to the hoisting rope. In the modified construction shown in Fig. 9, for discharging to shore, the hoisting rope c<1> and slueing rope d<1> are carried by a single derrick, and the carrier h is arranged as in the previous modification. For discharging into the barge u1 one end of the slueing rope d<1> is fixed to the apex of the sheer-legs v which are supported from the head of the derrick and connected to a weight w. Specification 105,801 is referred to.
