Abstract: 686,468. Machines for assembling buckles and straps. STEELS & BUSKS, Ltd. Feb. 20, 1951 [March 8, 1950], No. 5851/50. Class 43. In a machine for assembling buckles and straps means for releasably holding two buckles, one single-eyed and one double-eyed, are arranged side by side so as to hold each of the buckles horizontally disposed, means being provided for thrusting a strap through said buckles. The buckle-holding means carried by a frame 37 comprise two pairs of jaws lying in a common horizontal plane, each pair consisting of a fixed inner jaw 41 and an outer jaw 43 pivoted and spring-urged towards it. The cooperating edges of the jaws are grooved at 47 to form feed tracks for the buckles. The buckle magazines fit side by side in a box 39 carried by the frame 37, and are each provided with a longitudinal slit for viewing the number of buckles therein. The right-hand jaws, viewing Fig. 4, receive the double-eyed buckles. Two parallel, horizontal bars 34, Fig. 3, having at their working ends ribs 35 of reduced width which are stepped to provide shoulders, are slid forwards beneath the magazines on depression of a treadle, the shoulders serving to eject the lowermost buckles from the magazines into the feed tracks of the jaws. The double-eyed buckle 57 is pushed further forward than the singleeyed 56. Forward movement of the bars 34 is limited by the engagement of a link connected thereto with an adjustable stop-screw 60. A vertically reciprocable head 24 carries three strap-threading blades 48, 49, 50 which are aligned with the eyes of buckles held in the jaws 41, 43; the blade 50 ends in a hook 51, the blade 49 which is longer than the other two being recessed at the front to give access to the hook. By selectively draping a length of ribbon over a buckle, engaging it over the hook 51, and depressing or releasing a treadle to lower or raise the blades for the purpose of forcing the ribbon down through or pulling it up through the buckles, Figs. 7 to 11 (not shown), the ribbon is threaded through the buckles.

Abstract: 1,244,105. Reciprocating compressors. BITZER KUHLMASCHINENBAU G.m.b.H. Feb. 4, 1969, No.5898/69. Heading F1N. The oil-filled crank-case 2 of a reciprocating piston compressor is connected to the suction chamber 6 by a pipe 10 having an inlet 11 of increased area, whereby oil entrained in the gas flowing to the chamber 6 tends to deposit in the inlet 11 and drip back into the crank-case. A proportion of the oil reaching the suction chamber 6 collects in an oil settling chamber 7 and is returned to the crank-case through a non-return valve 13. If the pressure in the suction chamber is temporarily greater than in the crank-case, a non- return valve 14 closes the pipe 10. This excess pressure assists the return of oil through the valve 13. To minimize the amount of oil splashing into the inlet 11, the inlet is either covered by a baffle screen (12), Fig. 2 (not shown) or is situated close to the crank-case.

[Class 66] [Also in Groups I and IX] A continuous fine thread of quartz is made by feeding a coarse thread into a hot gaseous stream in the direction of flow of the gas, whereby the coarse thread is softened and is drawn into a continuous thread of microscopic fineness by the action of the enveloping,stream of gas. The coarse thread may be made by feeding a rod 10 of quartz glass slowly to an oxyhydrogen flame 11 and drawing it into a thread 6 by means of rollers 12. These rollers feed the thread 6 directly into a narrow tube 5 inserted axially in the nozzle 4 of an oxyhydrogen burner 1. The thread passes into the flame 7, and the softened material is blown out into a fine thread which may be intercepted at a short distance by a wall or plate where it collects in woolly form. The burner flame may be guided by walls or tube of refractory material, or the burners may be replaced by tubular electric furnaces. The fine threads may be made into yarns, felt, or fabrics, and they may be used for filtering, for electric or thermal insulation, or for sound damping. They may be mixed with other fibrous material if desired.

Title: Concentration of non-sulphide iron ores
IPC: B03D1/012
Filed: 1944-04-05
Abstract: Non-sulphide iron ores are treated with an acid substance the anion of which is a constituent of an acid having a dissociation constant not materially below 10-7, and subjected to froth flotation in the presence of a collector for such ores which contains oil-soluble petroleum sulphonates as its major active constituent.  The acid substance may be sulphuric, sulphurous, or phosphoric acid, sodium or potassium bisulphate, sodium chlorosulphonate, or waste gases containing sulphur dioxide.  The petroleum sulphonate may be the water-insoluble waste product, known as mahogany soap, obtained from the reaction of sulphuric acid and petroleum hydrocarbons, and it may be used either alone or dispersed in petroleum hydrocarbon, alcohols, coconut or other glyceride oil, or other oily solvent.  The ore may be de-slimed, or only partially de-slimed, before conditioning, which latter is preferably effected at high density and the conditioned pulp then diluted to froth flotation density before flotation. Preferably the acid substance is added in the conditioner, but it may be used in the de-sliming, in the flotation circuit, or be added at various stages.  Frothing agents such as pine oil, cresylic acid, and water-soluble reaction products of sulphuric acid with petroleum hydrocarbons, may be employed.  After a rough flotation, the collector may be removed from the concentrate by treating it with a dispersing agent and the concentrate then subjected to a cleansing operation using a flotation reagent which floats out silica or siliceous gangue.  Specifications 2359/09 and 19856/14, [both in Class 82 (ii)], are referred to.

Filed: 1975-02-14
Abstract: 1479705 Cameras SEIKO KOKI KK 14 Feb 1975 [18 Feb 1974] 6445/75 Heading G2A A camera has means for generating prior to shutter opening a pulse whose length represents object brightness, a counter for counting standard frequency pulses during the brightness pulse, means for generating a trigger pulse on shutter opening to call out the count to control the shutter opening time and means for terminating the count in the counter ahead of time if the trigger pulse is generated before the brightness pulse ends. Automatic operation. A brightness pulse from a generator 4 opens a NOR gate 5 so that standard pulses from a generator 3 can pass through gate 5 to a counter 7. Pulse counting ceases when the output of generator 4 inverts. This is normally controlled by a switching circuit 4-4 connected to a photo-electric integrating circuit 4-2, 4-3 but in low light conditions if the switching circuit 4-4 has not inverted by the time the shutter opens an input from circuit 18 inverts generator 4. Circuit 18 initiates the generation of subtractive pulses from standard frequency generator 3. When the count in counter 7 reaches zero, a detector 15 closes the shutter. To take account of film speed and diaphragm aperture an appropriate terminal 8-1 to 8-8 is selected to pass the additive pulses from generator 3 to a selected stage of a frequency divider 6 before counter 7 or to pass the pulses direct to a selected stage of counter 7. Manual operation. A terminal 8-1 to 8-8 is selected according to the desired shutter speed. No pulse counting takes place until the shutter opens, whereupon standard pulses from generator 3, pass through all the stages of divider 6 and then to counter 7. Switching elements 16-1 to 16-8 are connected to respective terminals 8-1 to 8-8 and to respective stages of the counter 7. When the counter stage corresponding to the selected element 16-1 to 16-8 is reached, the shutter is closed. An indicator circuit. Fig. 4, (not shown) comprises an array of LEDs (L1 to L5) which, in the automatic mode, indicate shutter speed, over and under-exposure when photography is possible and "overflow" when photography is not possible. The LED's are extinguished upon shutter release.
