Title: An improved apparatus for measuring the quantity of flowing gases
IPC: G01F15/04
Filed: 1920-07-09
Abstract: 147,892. Pintsch Akt.-Ges., J. Aug. 16, 1915, [Convention date]. Gas meters.-In an apparatus for measuring the quantity of flowing gases, the main gas stream is subdivided into a number of branches h, i equal to each other and only the quantity of gas passing through one of these branches i is ascertained by a meter b. The gas entering by a pipe e is controlled on its way to a casing n by a valve m operated by a pressure regulator a, and a part of the gas is by-passed at a branch g through the meter b. A pipe k connects the space above the regulator bell with the exit pipe of the gasmeter, so that the regulator is acted upon by the gas pressure in front of the nozzles h, as well as by the pressure in front of the single nozzle i. By this means, the gas pressures in front of and behind the nozzles through which flow the subdivided branches of the main stream are maintained respectively equal to the pressure in front of and behind the nozzle through which flows the measured portion of the gas.

Filed: 1977-05-12
Abstract: A cylindrical container comprises a casing (1) and closure parts (3, 7) present at each end. The casing (1) comprises an essentially rectangular cardboard strip bent to form a sleeve. The casing has an overlapping longitudinal seam (2) parallel to the container axis. At least one edge strip (21) lying at the opening of the casing is bent over inwards and is used for holding a closure part (3, 4). The edge strip (21) has a cutout (6) starting from the casing edge, so that, in this region, there is no overlapping seam and the longitudinal seam is not doubled in this part when the edge strips are bent over, but rather the two edges of the casing abut here in a flush manner. One closure part can be cardboard lid (3, 4) with an edge (4) which projects at right angles from the plane of the lid, lies between the casing (1) and the edge strip (21) bent over inwards and is fastened, for example, by adhesive bonding. The other closure part can be a plastic lid (7, 8, 9) which is removably inserted at the other opening of the case. The container can be manufactured, filled and closed in a particularly simple and rapid manner and can be used, for example, as a transport sleeve for drawings. <IMAGE>

Title: Improvements in feeding mechanisms for drilling machines and the like
Inventor: CARR VICTOR HENRY
IPC: B23B47/18
Filed: 1958-06-24
Abstract: 848,595. Drilling machine details. COMER, D. Dec. 1, 1958 [June 24, 1958], No. 20146/58. Class 83 (3). In a metal cutting machine the tool is fed intermittently in advancing steps, and retracted after each step by a pneumatic piston, the direction of movement of which is controlled by pilot valves which supply air to either side of the piston. A tool holder 17, Fig. 1, is secured to a rod, 34, connected to a plate 4 which is moved vertically by a pneumatic cylinder 6. The plate 4 abuts a collar 3 on a control rod 1 having an hydraulic dash pot 9 for controlling the rate of feed of the control rod 1. The rod 1 carries trips 10a-10c etc. for actuating the pilot valve 8, which reverses the supply of air to the cylinder 6 and thus retracts the tool. In operation, air is supplied to the cylinder 6, and the plate 4 is moved down carrying the rod 34 and the rod 1 with it. The trip 10a contacts a pawl 11 which pivots about 15 and actuates the valve 8, thus supplying air to the opposite side of the piston in the cylinder 6, and the tool and the plate 4 are ietracted but the rod 1 remains in the position where the trip 10a is in front of the pawl 11, due to a clearance hole in the plate 4 passing over the rod 1 and a collar 22 secured thereon. As the fully retracted position, a leg 23 on a plate 19 actuates a second pilot valve 7, and the supply of air to the cylinder 6 is again reversed, thus moving the tool, plate 4 and rod 1 down until the trip 10b actuates the valve 8. The action is repeated for each trip until a full depth trip 28, adjusted by a screw 27, actuates the valve 8. A roller 29, Fig. 2, attached to the trip 28 runs along a cam 30, which is in contact with the plate 19, and as the trip actuates the valve 8, the plate 19 is swivelled to bring a slot 21 between the collar 22 and the plate 4, and the tool, plate 4 and rod 1 are retracted, but due to the swivelling of the plate 19, the leg 23 does not contact the lever 24 on the valve 7 and the unit comes to rest. The leg 23 may be adjustable to ensure continuous operation of the unit. The unit may be applied to a machine tool slide.

Title: Electrical machining apparatus
Inventor: SENNOWITZ KURT HELMUT
IPC: B23H1/02
Filed: 1969-04-21
Abstract: 1,224,583. Electro-erosion. ELOX Inc. 21 April, 1969 [24 Aug., 1968], No. 20256/69. Heading B3V. [Also in Divisions H3-H5 and G2-G3] An electro-erosion apparatus comprises a power source 38 connected across the gap between an electrode 40 and workpiece 42 through an electronic switch 36 whose control electrode is triggered by a multivibrator including a pair of electronic switches 10, 12 providing a particular ratio, determined by means 24, between the on and off time pulses during normal operation of the apparatus and sensing means to sense any short and/or open circuit between the electrode 40 and workpiece 42 and responsive to initially reduce the on-off time ratio and then to restore it to the particular value. The pulse frequency may be altered by variable cross-coupling capacitors 20, 22 of the astable multivibrator and the on-off time ratio varied by a potentiometer 24. Open circuit conditions are sensed by a network including a resistor 94 and capacitor 96 coupled through a diode 98 to a second network including a resistor 108 and capacitor 100. The latter is charged from the transistor emitter 36 causing a transistor 86 to be turned on. If the gap voltage should drop, the signal is passed to the gap by a diode 102. A transistor 110 is turned on by the transistor 86, the negative voltage derived from a resistor 122 and potentiometer 124 connected across the supply 38, being passed through the transistor 110 and diode 130 to hold off the multivibrator transistor 10 until the capacitor 22 is recharged. Simultaneously, a transistor 112 is turned on by the negative signal at P to control the pulse on time of the multivibrator. A capacitor 136 is charged to maintain P negative for a predetermined time after the gap open circuit has been removed and the transistor 110 switched off. After the charge on the capacitor 136 has leaked off, normal operation of the multivibrator is ensured by a positive voltage source C. When the gap voltage falls below a reference voltage on a potentiometer 72 resulting in a short circuit, a transistor 60 is turned on which causes the transistor 86 to be switched on. The on-off time ratio is then reduced in the manner previously described. The transistor switches may be replaced by transistor banks, vacuum tubes, gate type devices, ignitrons, thyratrons, semi-conductor rectifiers.
