Title: Improvements in or relating to mechanisms for attaching an implement or the like to a tractor
IPC: A01B59/042
Filed: 1944-11-30
Abstract: 617,328. Vehicle couplings. FERGUSON, Inc., H. Nov. 30, 1944, No. 23940. Convention date, June 7. [Class 103 (v)] [Also in Group I] A coupling device between a tractor and a disc-harrow permits de-angling of the discs, for transport, as a result of the lifting of the front end of the coupling through the tractor powerlift. The power-lift arms 12 are coupled to links 16 which support a triangulated standard 45. The implement comprises disc gangs 27 mounted on a longitudinal draught beam 22 coupled to the links 16 by means of a hinged plate 25 permitting free vertical and lateral relative movement between tractor and harrow. The outer ends of the gangs are coupled by links 34 to fixed points on the beam 22 and the inner ends are coupled by links 32 to a slide 31 movable along the beam. The slide includes a standard 38 fastened by a chain 46 to the standard 45. Forward movement of the standard 38 and slide 31, to align the axes of the disc gangs 27, occurs automatically on raising the links 16 through the power-lift. The beam 22 (see Fig. 5) comprises L-shaped rails 35 through which the standard 38 passes, the rails being embraced both above and below by brackets 36, 39 forming part of the slide 31.

Title: Improvements in or relating to methods for making photo-micrographs and arrangements for use in performing the same
IPC: G03B7/08
Filed: 1962-06-22
Abstract: 969,811. Photomicrography; exposure control. ERNST LEITZ G.m.b. H. June 22, 1962 [June 28, 1961], No. 24076/62. Heading G2A. A light beam intensity control device for use in photomicrography comprises a device of variable light absorption arranged for insertion in a light path of a microscope by means controlled by a light sensitive member provided for measuring the intensity of the light beam after it has passed through the object so that the intensity of the light beam be adjusted for the exposure of photographic material of given sensitivity for a given exposure time. In the embodiment shown, light from a source ,1 passes through an object 5 which is photographed on a photosensitive surface 13 through a shutter 14. The shutter can be set to one of two speeds, one comparatively short the other comparatively long. For each speed the intensity of the light beam falling on surface 13 is varied by increase of a movable grey wedge or polarizing means controlled by a servomotor 19 and a control device 18. The device 18 is in turn controlled by a light sensitive element 17 on to which the light beam may be directed by means of a pivoted mirror 15. The object may be viewed by means of a half silvered mirror 7, reticule 9 and eye-piece 8.

Title: Improvements relating to electric heating elements
IPC: H05B3/52
Filed: 1944-12-02
Abstract: 592,049. Electric heating resistances. BULPITT & SONS, Ltd., and ASHTON, F. Dec. 2, 1944, No. 24122. [Class 39 (iii)] In the manufacture of an electric heating element in which a resistance wire, usually coiled, extends through a metal tube filled with an electrically insulating material such as fused magnesia or alundum, the latter is compacted against the tube wall by rotating the tube at high speed. In an example, insulating paste is drawn, by a vacuum device, into a tube 10. Annular plugs are inserted in each end of the tube, and permit the passage, through the tube, of a plunger rod of the same diameter as the resistance coil 22, to be used. This forces the paste against the walls of the tube, as at 23, where it is further compacted by high-speed rotation of the tube about its axis. The paste, which is preferably formed with a volatile liquid, is then slowly and evenly hardened in a muffle furnace. After removing the end plugs, the resistance coil 22 is inserted in the tube, one end of which is closed by an insulating bush 24 and sealing paste 25. A funnel 26 containing insulating powder 27, is screwed into the open end of the tube. This assembly is mounted vertically on a sleeve 33 which engages a rotating eccentric 32 whereby the assembly is vibrated to compact the powder 27 in the coil 22. The open end of the tube is then closed and the element is bent to the required shape.

The needle valves 23, 30 are attached by a yoke 38 for movement with a main oil supply on-off valve 21 so that the oil valve 21 opens at least before the needle valve 23 metering the oil to the nozzle. Cooling water or air flows through a pipe 43 to a tube 9 surrounding the conduit 10. The nozzle device is attached to the body 1 by a yoke 6 and locating pegs 4, the body 1 having transverse air and oil inlets 26, 18 enabling several bodies to be joined in a ring supply main.

Abstract: 532,293. Refrigerating. D'HALLOY, A. Aug. 24, 1939, No. 24410. Convention date, Sept. 13, 1938. [Class 29] Absorption machines. Ammonia or other refrigerant vapour evolved in a heated generator 13 rises through a column of oil 14 or other immiscible liquid cooled by external air or by waste cold from the evaporator and flows past a valve 16 into a liquefied refrigerant receiver 1 cooled by the evaporator 6. When the external temperature rises pressure is developed in the receiver and liquid refrigerant is forced therefrom through a tube 3 and valve 2 and issues through jets 5 into the evaporator space. This space communicates with the absorber 8, which is supplied with weak liquor from the generator by a pump 12 delivering to the interior of a porous tube 9. The strong liquor is returned by another part of the pump, which is driven by a turbine &c. 18 operated by refrigerant vapour under pressure taken by pipe: -,21 from the receiver 1 and exhausted by pipe 19 to the absorber. The heat supply to the generator is cut in when the pump is started, and continues until the receiver pressure drops at the attainment of low temperature.

Abstract: 282,116. Cozens, F. G., and Metallisation, Ltd. July 17, 1926. Coating; coating non-metallic surfaces with metals. - In a method of externally coating elongated articles such as pipes, tubes &c. by the metal spraying process, the various operations for metal spraying by heating, sandblasting and spraying are carried out simultaneously by arranging each article in a separate compartment and rotating each article with its compartment so that it encounters in succession heating, sand-blasting and spraying devices angularly arranged with respect to each other. The tubes f<1> are secured between chucks e<1> mounted on spindles d<1> which are carried by the arms c<1> of two triform brackets mounted on a shaft b carried by supports a, a<1>. The spindles d<1> are rotated by gears g<1>, h', the gears g' being driven from pulleys i<1> around which a wire rope j<1> passes. One of the pulleys i<1> is mounted on the shaft n of a gear wheel k driven by a wheel l from any convenient source of power. The shaft n also carries a worm m which engages a wheel o on a shaft p carrying at its top a pulley g around which passes a wire rope r to which is secured a tool holder s adapted to slide along bars t, t<1>. Fastened on the shaft b and at the bisections of the angles between the arms c<1> are sheet metal members which form the separate compartments for the tubes f<1>. In operation the triform brackets are moved until one arm c<1> is vertically downward and heat is applied to one of the tubes f<1> by a burner not shown, to remove fat, paint &c. The spindles d<1> are then rotated and the work holders s are caused to travel along the bars t, t<1> and so treat the other rotating tubes f<1> to the sand-blasting or spraying. The rotation of the spindles d<1> is then stopped, and the triform brackets moved through 120‹, and the spindles d<1> rotated again whereupon the heating &c. is carried out as before.
