IPC: B65D88/28
Filed: 1919-06-07
Abstract: 150,817. Vernon, W. N. June 7, 1919. Storage bins. - Opposite surfaces of bins for flow or like pulverulent material are provided with sections of different inclination to the vertical, the inclination being so small that the material as a whole may fall in a vertical direction, so that it does not " stick,'' and the arrangement being such that the sides alternately support and release the material to prevent " arching." Two constructions of bin are shown in Figs. 1 and 4, the material being supported by vertical sections b, 1<b>, and by inwardly inclined sections c, 1<c>. Outwardly inclined sections a, 1<a> release the material and allow it to fall. Instead of flat sections, concave and convex sections may be employed. The result of an arrangement of sections as shown in Fig. 1 is to produce sides substan. tially vertical in general direction, but having dog-leg or like bulges in staggered relationship down opposite sides of the bin. The bins may be provided with discharge conveyers, and may be arranged in nests or groups.

Title: Improvements in pneumatic or hydraulic clamping apparatus for butt welding or other machines
IPC: B23K37/04
Filed: 1957-05-09
Abstract: 817,166. Work-holders; welding by pressure. SCHLATTER A.G., H. A. May 9, 1957 [May 11, 1956], No. 14782/57. Classes 83 (3) and 83 (4). Pneumatic or hydraulic clamping-apparatus for butt-welding or other machines comprises two clamping jaws, the actuating cylinder of the first being directly connected with a feedpipe for the pressure fluid while the actuating cylinder for the second jaw is connected therewith through a control valve linked by adjustable members with this jaw, the latter having a clamping force greater than the first jaw even with the control valve fully opened. A workpiece 3, which may be a rail to be butt-welded to another rail (not shown), held by an adjacent part of the machine, is held between hydraulic clamping pistons 4, 5. The latter has a larger effective diameter than the former, and instead of being connected directly to the pressure source 21 through the line 26, as is the former, pressure fluid is supplied through line 261 to a chamber 27 in a control valve. In this valve the cone 29 and seating 30 form the opening located between chambers 27, 28 and controlling the pressure supplied to the clamping piston 5. The valve cone 29 is connected to a hand rotated spindle 33 which screws into a non- rotatable sleeve 35 connected through a rack- and-pinion gear with a lever 40 connected to the end of piston 5. The arrangement is such that movement of the hand wheel adjusts the clamping pistons in the direction of clamping while the work is still held. A hand wheel 14 connected by gears to a pair of screws 12, 13 adjust a slide 10 carrying the clamping cylinders &c. in a direction transversely to that described above.

Filed: 1970-03-26
Abstract: 1277989 Engine control systems DAIMLERBENZ A G 26 March 1970 [28 March 1969] 14796/70 Heading G1N [Also in Divisions F1 and G3] In an I. C. engine control system, operation of the or each inlet and exhaust valves 10, 11 and fuel injection is controlled electronically from a controller 12 in dependence primarily upon the phase angle of the crank-shaft and the position of the accelerator pedal. The inlet and exhaust valves 10, 11 are actuated by magnetic valves 22, 31 which receive control signals from the controller 12 and are inserted between highpressure accumulators 23 and pistons 21 attached to the inlet and exhaust valves. A magnetic valve 31 is provided between the fuel supply and the fuel injector 32. Phase angle and rotational speed of the crank-shaft are determined by a pulse transmitter 17, 18, 19, and position of the pedal 14 by a potentiometer 15. Other controlling parameters include combustion chamber pressure (sensor 36), temperature and humidity in the intake pipe 8 (sensor 37), smoke and/or temperature in the exhaust pipe 9 (sensor 38), and the positions of the inlet and exhaust valves (sensors 30). In a modification, Fig. 2 (not shown), the valves biasing springs 29 are omitted and pressure fluid is applied to both sides of the controlling pistons 21. In a further embodiment, Figs. 3 and 4 (not shown), operation of the inlet and exhaust valves is mechanical, via the usual cam-shaft, tappet, pushrod and rocker arm. However the phase of the crank-shaft and cam-shaft is variable by adjusting the chain guide between the crank-shaft and cam-shaft under control of the controller 12. Also, the longitudinal position of the cam-shaft may be adjustible, again under control of the controller 12.

Abstract: 780,773. Diaphragm pumps. S.U. CARBURETTER CO., Ltd. April 18, 1956 [May 26, 1955], No. 15188/55. Class 102(1). [Also in Group XXXV] In a diaphragm pump the plunger 1, Fig. 1, is electrically operated to reciprocate and transmit motion, through a low-viscosity fluid in chamber 58, to the pumping diaphragm 42. The liquid is delivered to the pumping chamber 61 from an inlet 47, Fig. 2, through filter 51 and non-return valve 49 and discharged through non-return valve 50 and an outlet 48, Fig. 2. When the pump is not in use the plunger i assumes its lowest position and the working end 63 of the plunger 1, which is rounded, fits a depression 64 in the pumping chamber such that the diaphragm 42 is deformed to an extent that the volume of chamber 58 is increased by more than the volumetric displacement of the stroke. This prevents possible leakage of the fluid past the plunger 1. In operation the plunger 1 is urged downwards by the leaf springs 12 and upwards by a solenoid 3, stops 13 and 14 being provided. The make and brake of the electrical connection to the solenoid is controlled by the tongue 29, Fig. 2, of the blade-spring 26. When the plunger 1 is at the end of its downstroke the toggle device 33, 36 leans such that the top of the bow spring 36 leans towards the stem 32 so that the tip of the spring tongue 29 is deflected downwards and electrical connection is made between the contacts 25 and 22. This contact remains until the plunger 1 returning upwards causes an opposite action on the tongue 29 through the lower shoulder of the notched portion 31 of stem 32, when the contact is broken. The chamber 59 above the plunger is vented to atmosphere through a slot in stop 13 and an aperture 60 which also allows one end of the solenoid winding to be taken through the membrane 15. The membrane 15 prevents dust entering the chamber 2.

Title: Method and press for compacting metallic powder
IPC: B30B1/26
Filed: 1944-08-11
Abstract: 610,011. Moulding metal compacts. AMERICAN ELECTRO METAL CORPORATION. Aug. 11, 1944, No. 15391. Convention date, Sept. 1, 1943. [Class 87(ii)] A method of pressing a loose fill of metallic powder into a compact having a shape including portions (e.g., A and B, Fig. 6) whose thicknessses, measured in the direction of pressing, differ considerably, the ratio of the thicknesses of uncompressed fill to the thicknesses of compact equalling the ratio of the density of the compact to the density of the fill, is characterized by the steps, carried out simultaneously, of compressing the fill portions individually, unyieldingly and in the same compression ratio. A telescopic punch may be used. From the dimensions of the finished compact 51 and a known compression ratio, the dimensions of the mould cavity 60 to be filled with metal powder are calculated. In Fig. 5 the powder is shown in the process of compression. The lower telescopic punch comprises the independent plungers 66, 67 which are actuated by the cams 70, 71 by means of pins 76, 77 and 80, 81 engaging in opposite grooves 78, 79 and 82, 83. The upper plungers 68, 69 are actuated in the same manner by the cams 73, 74, the two cam shafts 72, 75 being driven in synchronism. The grooves in the cams are so designed that the punches start from their original positions, Fig. 4, and reach their final positions, Fig. 6, simultaneously. After this final position has been reached the upper punch is withdrawn completely from the mould and the plungers 68. 69 returned to their original positions, Fig. 4. Meanwhile, plunger 67 is driven further upwardly to eject the compact, the plunger 66 remaining in its final position during this operation. The lower plungers are then returned to their starting positions. Instead of cams or eccentrics, individual hydraulic, geared electric motor &c. drives may be used to operate the plungers through levers. A single compression method may be used with a stationary bottom to the mould and a single telescopic punch such as 68, 69. Alternatively the bottom punch may be telescopic and the upper punch formed from a single plunger in the usual manner. Compacts suitable for use (after sintering) as rotors in electric (impulse) generators may be made.
