Title: Device for pneumatic or hydraulic readout and storage of information from perforated information carriers
IPC: F15C3/06
Filed: 1965-11-01
Abstract: 1,070,129. Sensing records. SUNVICREGLER G.m.b.H. Nov. 1, 1965 [Nov. 21, 1964; March 17, 1965], No. 46096/65. Heading G4M. A record such as a perforated tape 10 is sensed by means of a stream of air supplied through duct 24 to a channel 26. Air passing through perforations 22 in record 10 raise corresponding balls 62, the air escaping through lateral openings in the bores in plate 46. By subsequently applying pressure through these openings, the raised balls 62 are lifted higher to close a pair of contacts 58 and the remaining balls 62 are held down to close contacts adjacent to bores 38. The balls in the bores in plate 28 act as relief valves and prevent pressure being applied to record 10 during the read-out operation. In another embodiment, Fig. 4 (not shown), air pressure for sensing is applied through ducts (92), and those balls (90, 104) associated with non-perforated regions on the record are raised.

Title: Rotary connection for pipes subjected to internal pressure
IPC: F16J15/10
Filed: 1970-09-29
Abstract: 1,254,986. Rotary pipe joints. MANNESMANN A.G. 29 Sept., 1970 [30 Sept., 1969], No. 46323/70. Heading F2G. A rotary, pipe includes a sealing ring 10 located between inner and outer rings 8 and 9, secured to inner and outer bearing races 6 and 5 respectively, and the sealing ring 10 is axially located by flanges 13 and 14 acting in conjunction with spacers 15 and 16. The location of the sealing ring 10 radially inwardly of and at the same axial location as the ring of rolling elements (balls 7) minimizes the change in dimension of the gap to be sealed occasioned by bearing play. The elasticity of the material of the sealing ring can therefore be relatively low. The radial position of circumferentiallyspaced elements 16 may be adjusted by bolts 17 to adjust the axial location of spacer ring 15, which engages elements 16 through inclined wedging surfaces.

Title: Arrangement of a plurality of valve stages for the programmed  control of compressed air
IPC: G05B19/44
Filed: 1971-10-05
Abstract: 1361076 Fluid logic and switching circuits K FRIEBE 5 Oct 1971 [5 Oct 1970] 46340/71 Heading F1P In a compressed air logic switching circuit wherein at least two valve stages A, B each contain at least one slide valve 30a, 30b having an opening end 39a, 39b of greater crosssectional area than the closing end 40a, 40b and wherein each slide valve is moved from its closed to open position by application of a signal pulse to its open end via control input line 36a, 36b resulting in compressed air in a supply line 48, 33 being directed through a ring gap in the open valve into an output line 35a, 35b the closing ends 40a, 40b of the slide valves of each stage are connected together by lines 42a, 42b and 44. Connecting line 44 leads to an accumulator 46 having a throttled vent 47 as does a line 45 connecting output ends 41a, 41b of return valves 31a, 31b. In operation and with a signal in line 36a but not in line 36b, valve 30a is lifted from the position shown thereby connecting supply line 33 to output line 35a after which any remaining control pulse is relieved past return valve 31a and through line 45 to accumulator 46. The resulting pressure rise in the closing end 40a of valve 30a is transmitted through lines 42a, 44, 42b to end 40b of valve 30b to close the latter. Similarly on applying a control signal to line 36b but not to line 36a valve 30b is opened and valve 30a is closed. Control signals may be transmitted to lines 36a, 36b through a pulse transformer 49 only one of which is shown. In order to quicken exhaust of the two ends of each slide valve and to lock the system between switchings, an exhaust valve (51a, 51b) Fig.2 (not shown) is located between slide valve (50a, 50b) and return valve (52a, 52b) upstream of which is an input check valve (53a, 53b). The circuit also includes a main exhaust valve (79). A diaphram slide valve for use in the circuit comprises large and small diaphrams 102, 107 Fig. 3 spaced by pistons 103, 104, 106 which are moved to the left on application of a signal in control line 57. Supply air in a line 69a then gains access to output line 70a and through bores 108a, 108b, 108c of piston 104 to a cylinder space 109 thereby holding the system in the L. H. position after the input signal at 57 ceases. With a signal in line 74, piston 106 is urged against piston 104 which is moved to the right whereby line 70a is vented to atmosphere at 108d and the valve remains in the rest position shown. The circuit may be assembled in "building block" form and the outputs used to control one or more compressed air actuated motors e.g. for operating a deep drawing press.

Abstract: 1,139,356. Automatic control of current and voltage. CONTEMPORARY ELECTRONIC PRODUCTS CORP. Oct.21, 1966 [Oct. 22,1965], No.47185/66. Heading G3R. A voltage regulator circuit comprises a D.C. input supply source 10; a switching circuit 16 having input terminals 14, 15, output terminals 17, 18 for connection to a load 19, and a switching transistor 35 which is associated with control transistors 36, 57 and which is connected in series with a current sensing resistor 36 and an inductor 38 between terminals 14 and 17; a voltage comparison unit 22 which includes a reference Zener diode 118 and transistors 108, 109 connected as a differential amplifier, the unit being connected to sense the output voltage at terminal 17; an amplifier 23 which receives an input from the current sensing resistor 36; and a control unit 21 which includes transistors 65, 66, 67, 68 and which receives inputs from the units 22, 23, an input from a secondary winding 49 of the inductor 38 and an input from the input terminal 14, the unit 21 being effective to control the switching of transistor 35. In operation, the unit 21 acts to switch on the transistor 35 in the absence of a signal from the current sensing amplifier 23 so that current flows from the input source 10 to charge a capacitor 39 connected across the output terminals 17, 18; when the load current, as sensed by resistor 36, reaches a predetermined value transistor 35 is switched off by unit 21 in response to a signal from amplifier 23; the energy then stored in inductor 38 then flows through rectifier 48 and capacitor 39, this current flow inducing a signal in the secondary winding 49 which signal is applied to unit 21 so that the latter will not act to render transistor 35 conductive during the time that current is decaying through inductor 38; when this current has decayed sufficiently, transistor 35 is switched on again and the cycle is repeated so that pulses of current are delivered to the load. When the load voltage reaches a predetermined value, set by the adjustment of a rheostat 116, a signal from unit 22 is applied to unit 21 to prevent transistor 35 being turned on until the output voltage falls below the desired value. When the power supply 10 is first switched on, a signal from terminal 14 is applied to unit 21 which is thus prevented from rendering transistor 35 conductive until the input voltage reaches the desired value, so as to prevent damage to the various transistors, which damage could otherwise be caused by an insufficient input voltage.

Abstract: 1,076,400. Shutter operating mechanisms. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Dec. 22, 1964, No. 52019/64. Heading G2A. In a photographic camera having two shutter elements, thrust rods 37, 47, operated by the winding mechanism, are provided, the rod 47 being connected to the release mechanism for the elements and the rod 37 being connected with the driving devices for the elements. Rotation of a winding handle 1 causes a cogwheel 7 to rotate. This motion is transmitted to a film transport sprocket 22 and thence, via cogwheels 26.29 to a film take up spool 32, thus allowing the film to be moved forward one picture frame. Rotation of the spool 32 displaces the rod 37 as long as a bolt 35 is situated in a recess and cocks the shutter via levers 43 and 45. Winding up of the shutter is stopped when a bolt 38 contacts the end of a groove 39 causing the rod 37 to be disengaged from the recess 36. Rotation of the cogwheel 7 also results via a bolt 11 and a rod 18 in a displacement of the rod 47 which stresses a release spring 59 and rotates discs 51, 54 and 62 until a lever 64 locks behind a lug 63. Simultaneously a bolt 19 on the rod 18 reaches the end of a groove 20 causing the bolt 11 to slide out of the recess 17 and stopping movement of the rod 18. Rotation of the disc 54 causes a release lug 56 to move out of contact with a lever 67 which then snaps home in a recess 25 to prevent further film movement before exposure.
