Title: Improvements in or relating to machines for operating upon the margins of boot or shoe soles
IPC: A43D43/02
Filed: 1941-04-29
Abstract: 548,973. Channelling shoe soles. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., and PRATT, J. W. April 29, 1941, No. 5528. Addition to 525,408. [Class 31 (i)] Modifications are made to the power-driven cam for shifting the edge gauge, described in the parent Specification, and its actuating mechanism. The cam is readily removable so that it may be changed, and is reversible for the other shoe of a pair. The cam actuates devices to de-clutch its own drive at the end of a cycle and at one or more predetermined times in the cycle. Removal of the work engages the clutch to bring the cam to starting point if it is not already there. The clutch is closed by mechanism operated by hand, and is opened automatically when it is required to stop the cam rotating.. The cam 25 is carried by a block 29 driven by reducing gearing 47, 49, 53, 55 from a clutch 67 adapted to be driven by a pulley 75. The cam is positioned by a spring plunger 31 and is held in place by a collar 43 secured to the block by a bayonet coupling. The clutch is urged to closed position by a spring 99 and is freed by a push-rod 95 actuated by a lever 105 linked to a lever 121 carrying a wearplate 125 co-operating with a similar plate 133 on an arm 127 pivoted to a lever 131. The arm 127 is actuated by a latch 153 when a hand lever 149 is depressed to start rotation of the cam. The lever 131 is swung counter-clockwise to free the clutch when a pin 141 engages a wedge 139 on the lever at the end of the cycle. The clutch is also freed when any one of five pins 161 slidable in the block reach the wedge 139 unless the cam has an opening in line with a pin. If the particular cam in use has not completed one rotation at the end of the machine's cycle, the depression of the work support at the end of the cycle engages the clutch by mechanism connected to a slide rod 169. Specifications 25730/06 and 13052/08, [both in Class 31], also are referred to.

Title: Improvements in or relating to absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1933-02-23
Abstract: 415,417. Refrigerating. ELECTROLUX, Ltd., Luton.-(Assignees of Platen Munters Refrigerating System Aktiebolag ; 2, Norrmalmstorg, Stockholm.) Feb. 23, 1933, No. 5535. Convention date, March 5, 1932. [Class 29.] Absorption systems.-The vapour expelled from the generator is cooled by cold weak liquor to effect rectification, the weak liquor thus used being branched off from the supply conduit to the absorber at a point beyond the usual liquor heat-exchanger and preferably being returned to the generator. In one arrangement a branch conduit 32, Fig. 1, connected at its upper end to the liquor inlet to the absorber 17 is led downwardly through apertures in baffles in an upright rectifier vessel 29 through which the expelled vapour flows upwardly from the lower end of a conduit 28 connected to the generator 10 and on to a pipe 30 leading to the usual air or condensate cooled rectifier 11 and to the condenser 13. Condensed solvent flows from the rectifier 29 through a pipe 34 back to the strong liquor conduit 22. The weak liquor pipe 32 is continued as a heated " pumping " coil 35 and riser pipe 36 to convey the liquor to the top of the generator. In the arrangement shown in Fig. 3 the whole of the weak liquor circulates through an inclined rectifier vessel 29 after it has been cooled once in the usual liquor heatexchanger 40 and the heat of rectification is recovered by passing the weak liquor conduit again through the same heat-exchanger and through a second shorter heat-exchanger 43. In a further arrangement the weak liquor from the branch conduit 44, Fig. 4, is lifted in a vessel 45 by the admission of the expelled vapour to the liquor conduit, and flows back through a pipe 46 to the generator. The vapour passes on through a pipe 47 to the rectifier 29. The pipe 34 leading condensed solvent vapour out of the rectifier is made large enough for the upward flow of vapour evolved from the strong liquor in the heat-exchanger, which is inclined to facilitate the rise of this vapour. In another arrangement, Fig. 5 (not shown), the weak liquor branch conduit, after passing through an inclined rectifier, is continued as a coil in contact with a metal sheath surrounding the insulation of the generator, where it serves to heat the insulation, and is then led a second time through the rectifier and finally formed into a pumping coil and lift pipe. In another arrangement, shown in Fig. 6, the rectifier 29 is located at the side of the generator insulation 53, in which a metal sheath 50 is embedded. The lower part 55 of the rectifier is located near the hot part of the generator in order that vapour re-absorbed in the rectifier may be expelled. The vapour expulsion pipe 28 is led alongside and soldered to the metal sheath 50 so as to heat it and thereby reduce radiation losses. The system provides an improved liquor heat exchange, as claimed in Specification 415,445. Specification 400,053 also is referred to.

Abstract: 1,211,117. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 Feb., 1968 [7 Feb., 1967], No. 5597/68. Heading H1K. In a method of producing integrated complementary transistors T1, T2, an N-type epitaxial layer is formed on a P-type substrate 1 and divided into . islands by the diffusion of P-type impurity to form isolating wall regions 5a, 5b, 5c. The emitter 10 of transistor T2 is diffused simultaneously in one island, the existing epitaxial layer 4 forming its base, and substrate 1 its collector. The base 7 and emitter 8 of transistor T1 are then formed by diffusion in a further island, the epitaxial layer 3 forming its collector. The isolating walls 5a, 5b, 5c are formed by providing doping material deposits opposite one another on either side of the epitaxial layer at positions where walls are required, those buried below the layer having been provided before the deposition of the layer itself, and diffusing in a neutral atmosphere. In this same process a further doping material deposit on the free surface of the epitaxial layer is diffused to form region 10. Regions 7, 8, 9 and 12 are formed at a later stage by diffusion in a conventional manner. A method of manufacturing three integrated complementary transistors is also described. Specification 1,210,981 is referred to.

Title: Apparatus for measuring the index of filterability of a liquid
IPC: G01N15/06
Filed: 1973-02-06
Abstract: 1358527 Measuring liquid filterability ENTREPRISE DE RECHERCHE ET D'ACTIVITIES PETROLIERES (ELF) 6 Feb 1973 [28 Feb 1972] 5873/73 Heading G1N The index of filterability of a liquid, i.e. the temperature at which the flow rate of the liquid through a standard filter under a standard pressure drops below a given value, is measured automatically. In Fig. 1 the standard filter 18 divides test cell 16 into two chambers, the right hand chamber receiving a liquid such as fuel oil from constant pressure regulator 6 and the left hand chamber being connected to flow rate meter 11. The cell is surrounded by cooling bath 28 so that as liquid enters the cell it is cooled. When the flow drops below a pre-set rate, meter 11 passes a signal to gate 33 and this passes a signal from temperature sensor 20 in the cell to amplifier 35 and recorder 36. The meter signal also activates relay 22 and current is passed through a heating coil 27 around the cell for a predetermined time. This warms the liquid, flow increases, and the whole process repeats, the capacitor 34 storing the temperatures between each measurement. If the meter 11 is sensitive and the thermal lag of the cell is small, a series of temperatures which differ only slightly are recorded, Fig. 2, (not shown), and these give the index of filterability. The flow meter is preferably a float type rotameter (R.T.M.) with the float interrupting the path between a light source and a detector when the flow drops below a given value. The float position may alternatively be found magnetically. The flow may also be measured by a heated wire device or by determining the thickness of the flowing stream by its optical absorption, or by measuring the pressure across the filter. The cell may be cooled by a bath, by Pettier effect devices or a Ranque tube, while heating may be by wire or plate electric heaters, or by passing a current through the cell itself. The temperature sensor may be a thermocouple, a resistance probe or a transistor. The liquid to be tested has any impurities removed by a pre-filter 2 in Fig. 1, and water is removed by a coalexer 3.
