Title: New or improved machinery to be used in the manufacture of tin boxes, cans and the like
IPC: B21D51/26
Filed: 1919-05-17
Abstract: 143,709. Bennett, G. H., and Williamson, G. E. May 17, 1919. Feeding tin boxes and cans.-In a machine for assembling tagger or other flanged end disks d on the ends of the bodies c of cylindrical tin boxes, cans, &c., the bodies are carried in a chain carrier, the links of which have vertical webs b having semicircular recesses b<1> at each end, so that the ends of adjacent links are open to receive the bodies as they pass over the hexagonal or other polygonal chain-wheels a but close over the bodies as they pass along the straight portion. The straight portion is kept taut by rollers k mounted in adjustable brackets l. The can bodies are supplied mechanically or by hand to an inclined shoot e down which they roll to the chain. When disks of ordinary or thick tin plate are used they are supplied by an endless conveyer to a shoot f provided with V-shaped ribs, Fig. 3, the space between which is only slightly greater than the width of the flanges so as to prevent jamming of adjacent disks. The lower end of the shoot terminates in an inclined slot so that the disk as it falls from the shoot projects across the path of the can body, which just engages the front end of the flange of the disk and thus carries it forward against one of the vertical guide plates h which effects the complete engagement of the disk with the end of the body. The portion of the guide plate against which the end of the disk bears when being drawn out of the slot may have pressure springs to enable it to yield. The guide surfaces h are bevelled at one end so as to engage the ends of the can body to position it before it is clamped by the chain links. The. completed blanks are transferred to a shoot i<2>, by curved fingers i, and may pass to a receptacle, or, if desired, to a soldering machine. End disks may be applied simultaneously or in succession to opposite ends of the can bodies. When using tagger or other thin end disks, the shoot f is dispensed with, the disks being conveyed flange downward by an endless belt m under guide bars r, s, the bar s being suspended by a pair of links c and bearing on the disks so as to ensure their positive feed. The disks push each other up a curved plate u under a curved guide u<2>, until they reach a spring-pressed stop v, in which position they project into the path of the bodies through an opening in the vertical guide-plate h. The can body engages one edge of the disk and first turns it on its two points of support. It then lifts the stop v and also the disk, which then coincides with the body, whereupon the edge of the body engages the forward flange of the disk, which is finally pushed on to the body by the guide plate h,

Title: Improvements in high energy output electric discharge devices and methods of operating same
IPC: H01J19/36
Filed: 1923-05-11
Abstract: 197,689. Western Electric Co., Ltd., (Assignees of Oswald, A. A.). May 12, 1922, [Convention date]. Vacuum or low-pressure apparatus, arrangements of.-A thermionic valve rectifier for large outputs, having an anode maintained at a high voltage, for instance 10,000 volts, and cooled by a liquid or other medium, constituting a high resistance path between the anode and earth, is provided with means for automatically opening the supply circuit to the anode and operating an alarm upon a decrease in the supply of cooling medium. The cathode is earthed. As shown, the anodes 12 of two valves 10, 11 are mounted in cooling chambers 26, and coiled flexible insulating tubes 45 are interposed between the supply and outlet pipes 47, 48 and the inlet and outlet ports 27, 28 respectively of the chambers. The water in the coiled tubes constitutes a high resistance path between the valves and water mains and earth. The outlet-liquid passes to a control device comprising a pipe 49 with a constricted portion 50 connected with a chamber 52, which contains mercurv 54 and is in communication with another chamber 53, the upper end of which is connected with the pipe 49. A float 56, supported by the mercury and guided by a sleeve 58, operates the lever 59 of a switch for controlling an alarm 71 and the main supply circuit-breaker 3. The anodes are supplied through two thermionic rectifiers 5, 6 connected across the secondary of a transformer 4, the primary of which is connected with the main supply circuit through the circuitbreaker 3 and an overload release coil 8. A novoltage release coil 9 is normally energized by a battery 68 through switch contacts 63, 64 in shunt with a resistance 70 and a relay 69 operating the alarm 71. When sufficient water is flowing through the pipe 49 the contacts 63, 64 are closed by the float-operated switch, but if the supply of water decreases, the float rises and opens the contacts. The alarm relay 69 is thereby operated and the switch 3 opened as the current through the coil 9 is reduced by the resistance 70 below the strength necessary to hold the armature of the coil 9. Adjustment of the switch may be effected by means of a set-screw 62. A bypass 100 with a valve 101 may be connected across the constriction 50 so as to allow a larger flow of water without readjustment of the control mechanism. The input circuit is connected between the grids 19 and the cathodes 18 and the output circuit is coupled through a transformer 23 with the aerial; the input and output circuits may be coupled together and used in conjunction with a condenser for generating oscillations. A choke 14 prevents the passage of high frequency oscillations to the valves 5, 6.

Title: Process of refining liquid carbonaceous materials such as petroleum products and residues, asphalt and the like
IPC: C10G45/04
Filed: 1930-04-25
Abstract: Liquid carbonaceous materials such as petroleum products and residues, and asphalts, particularly those containing sulphur, are refined by heating under pressure in the presence of reducing gases such as hydrogen or gases yielding hydrogen and in the presence of a catalyst of chromium or chromium compounds brought in colloidal state on to a carrier such as pumice stone, active carbon, finely divided coal, silica gel or porous clay.  The catalyst may also contain molybdenum or its compounds.  The reaction is preferably carried out at moderate temperatures, such as 400 DEG  C., and for a short period, to avoid splitting of the molecules.  The catalyst may be prepared by reducing a solution of chromic acid with hydrogen sulphide and absorbing the product on a decolourizing carbon known by the registered Trade Mark of Norit.  Examples are given of the treatment of a lubricating oil with a catalyst so prepared and also with a catalyst containing in addition molybdenum oxide. Specification 331,199, [Class 1 (i), Chemical processes &c.], is referred to.

Title: Improvements in or relating to apparatus for utilising waste heat
IPC: F25B39/00
Filed: 1952-05-21
Abstract: 744,817. Refrigerating; heat pumps; tubular heat-exchangers. COWLEY, G. May 20, 1953 [May 21, 1952], No. 12840/53. Classes 29 and 64(3). A receiver-evaporator unit 26 for a compression refrigerating system operating as a heat pump comprises an inner chamber 28 to which liquid refrigerant is supplied from the condenser through a non-return valve 31 and an outer chamber 27 to which liquid flows from the receiver through an expansion valve 32, the outer chamber being connected to the compressor suction through a pipe 34. The outer chamber may be subdivided by radial partitions 36. An evaporator coil 5, Fig. 1, may be disposed around the unit 26 and is in circuit between the pipe 34 and the compressor to receive any refrigerant not evaporated in unit 26. Fluid, e.g. water, containing waste heat flows through a pipe 10 to a settling chamber 9 whence it passes through a filter 13 to a cooling chamber 2 containing the unit 26 and the evaporator 5. A by-pass 15 is provided and the amount of water through the by-pass is regulated by valves 17, 16 in the pipe 10 and the by-pass respectively. Chambers 9, 2 have, respectively, overflows 24, 42 discharging into the by-pass and drainage apertures 19, 20 closed by plugs. If the fluid to be cooled is air it is introduced into chamber 2 through a pipe 25. Deposits are removed from the unit 26 and evaporation 5 by scrapers 40, 37. The condenser, not shown, may be of stream-lined cross section with integral surface-enlarging members. The liquid refrigerant from the condenser is further cooled by cold gas returning from the evaporator in a heat-exchanger having the cross-section shown in Fig. 7, the inner pipe 44 carrying the liquid being provided with inner and outer radial fins 44a, 44b. The cold gas can flow through a by-pass around this heat-exchanger under the control of thermalresponsive elements so that heat exchange occurs only when the gas is colder than the liquid coming from the condenser. In a modified form, the chamber 9 is above the chamber 2 and the water flows from the former to the latter through a horizontal filter. As shown in Fig. 8, moisture-laden air from a drying plant is blown by a fan 51 over the unit 26 located in a vertical casing 50, the condensed water running off through a drain 54. The chilled air then passes over the compressor and the condenser 56 to be returned through a screen 57 to the drying plant. Alternatively, the air cooled by unit 26 can be exhausted and a fresh stream of air heated by the condenser 56. If the condenser be used to heat water, scale may be removed therefrom by temporarily reversing the system so that the condenser acts as an evaporator.
