Title: Improvements relating to the lubrication of internal combustion engines
IPC: F01M3/04
Filed: 1927-09-27
Abstract: 290,892. Bate, B. D. Sept. 27, 1927. Lubricant conveyed by fluid; lubricating by solid lubricant. - A spring-pressed piston c arranged in a cylinder a disposed beneath a hopper b containing flaked graphite or other lubricant carries a grooved or fluted stem e which projects through the passage between the cylinder and the hopper into the latter, a port f in the upper part of the cylinder being connected by a pipe r to the induction system of an internalcombustion engine, whereby the reciprocations of the stem due to the fluctuating suction action cause lubricant to be fed from the hopper into the cylinder, whence it is carried, along with air entering through a port h, to the engine. The ports f, h, which are controlled by valves g, i, are so arranged that, while the port f is never closed by the piston, the port h is closed when the engine is running light, with a subsequent high vacuum; at such time a valve d! farmed at the lower end of the stem e also closes the passage between the cylinder and the hopper. In the lower position of the piston c, a stem k depending therefrom abuts against an adjustable stop j. An annular groove n around the stem e communicates with the atmosphere by a valvecontrolled passage o, whereby excessive feeding from the hopper is prevented.

Title: Improvements in or relating to heat exchanger cores
IPC: B21D53/08
Filed: 1964-06-23
Abstract: 1,075,272. Tube and fin radiator cores. SOC. ANON. DES USINES CHAUSSON. June 23, 1964 [June 27, 1963; Dec. 16, 1963], No. 25989/64. Heading F4S. The invention concerns fin plates for an air-cooled radiator core incorporating a plurality of fluid flow tubes extending through registering slots in a stack of fin plates. The slots for the tubes are made as follows: for each slot a cut is made in the fin plate having the configuration shown in Fig. 2 or Fig. 10, thereby forming opposed tongues which are subsequently bent out of the plane of the plate to form upstanding flanges (8, 9) parallel to the sides of the slot and of a height equal to half the width of the slot. Integral with the flanges are spacers which may be parallel to or inclined away from the tube and which may be arched for additional rigidity or turned over at their ends to form bearing surfaces for a contiguous plate. Alternative forms of cut, Figs. 6, 7 and 8, 9 (not shown), may be used if the spacing between the fin plates is to be less than the thickness of the tubes. Slats (25) may be pressed out of the fin plates between the tube slots and stampings (26) on the edges of the plates enhance rigidity and may be used to distinguish the front and rear edges of the plates by the omission of some of the stampings on one edge. A rib (27), pressed in the plates between two rows of tube slots, also enhances rigidity. All the flanges, slats, spacers, stampings and ribs may be raised on the same side of the fin plate and the rib (27) may be used to guide the fin plate during manufacture.

Abstract: 299,038. Bemberg Akt.-Ges., J. P. Oct. 20, 1927, [Convention date]. Ammoniacal - copper cellulose solutions, processes and apparatus for making filaments from.- The manufacture of artificial silk from ammoniacal-copper cellulose solutions by the stretchspinning process is so conducted that the threads leave the spinning funnel in a plastic condition and are subjected to a second considerable stretching after leaving the funnel. This second stretching may take place before or during the final hardening with acid. Suitable apparatus comprises a spinning funnel 1, Fig. 1, from which the thread passes round a guide-rod 9 to positively driven rollers 2, 3, the roller 3 rotating at a greater speed than the roller 2. Acid is supplied to the roller 3 from a channel 4, and the stretched thread is guided by a roller 5 to a centrifuge 6. The rod 9 may be dispensed with and the roller 3 replaced by a bobbin rotating in a trough fed with acid, or the thread may be treated with acid on its way from the roller 2 to the bobbin. Alternatively, the rod 9 and roller 2 may be replaced by a system of rods which conduct the thread in a zig-zag path and are so arranged that their stretching action does not 'extend backwards to the spinning funnel. Specification 212,068 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the second stretching may take place immediately after the acid treatment.

Title: Improvements in or relating to methods of synthesizing compound semiconductor crystals
IPC: C30B25/02
Filed: 1962-07-09
Abstract: <PICT:0996020/C1/1> <PICT:0996020/C1/2> Group III-V compound semi-conductor crystals may be grown epitaxially upon a substrate by transporting the Group III element to the substrate in the form of a gaseous compound with a halogen carrier, transporting the Group V element to the substrate in the form of a vapour and causing the vapours to react, the pressures of the constituents of the reacting vapours being determined to impart a selected conductivity type to the synthesised crystal. The preferred halogens are chlorine, bromine and iodine. As shown, Fig. 1, a quartz reaction tube containing a monocrystalline seed wafer of compound AB (e.g. gallium arsenide), a quantity of source material of compound AB and a measured quantity of halogen X is evacuated and sealed.  The tube is heated to constant temperatures T1 at the seed site and T2 at the source site such that T2>T1, and the source AB is transported into the vapour phase and hence on to the seed upon which it is deposited epitaxially.  The process may also be applied to an open tube dynamic flow system as shown in Fig. 3. An inert gas D such as helium, neon, argon, krypton, xenon or radon is introduced into a quartz reaction tube at a constant flow rate.  The gas D flows over a halogen X maintained at a temperature T3, the flow rate and temperature of the inert gas thus determining the quantity of X introduced into the vapour phase.  The vapour of X is carried towards an element A maintained at a temperature T4, and reacts to form AXx and AXy in the gaseous phase. In a separate tube a quantity of element B is maintained at T5.  A separate supply of gas D flows over B causing some of this element to enter the gas phase.  The two streams are mixed and carried to the vapour growth chamber containing seeds of AB at a temperature T6 which is lower than T4.  The change of temperature from T4 to T6 causes the ratio of vapours AXx and AXy to change through disproportionation and in the presence of B the compound AB is synthesized on the seeds.  By successive depositions PN junctions can be formed.
