Abstract: 1,269,170. Packing gramophone records. DEUTSCHE GRAMMOPHON G.m.b.H. 29 July, 1970 [25 Sept., 1969], No. 36657/70. Heading B8C. A record 12, after final processing by an edgetrimmer 2 serving a plurality of press or injection moulding machines, is lifted from a disc 5 by means of a suction plate 13 on a lever 14 and dropped through a slot 15 in a work bench 1 into a record sleeve 16. The record sleeves 16 are lifted into a vertical position from a sleeve store 17 of convex curvature by a suction frame 18 and are held open by suction cups 19 on reciprocable rods 20. When the record is in the sleeve 16, the suction to frame 18 and cups 19 is cut off and the sleeve and record fall into a box 21. In a modification (Fig. 2, not shown), the sleeves are held vertically in a sleeve store adjacent the packing position, are removed from the store by a reciprocable suction plate (26), are held open by a reciprocable suction frame (29) and slide down a shoot (30) into a container (31). In a further modification (Fig. 3, not shown), the sleeves, held vertically in a store adjacent the packing position, are removed by suction cups (34) on reciprocable rods (35), are opened by short brushes (37) on the sleeve store and by an auxiliary air jet (38), and fall vertically into a container (40). An identical arrangement for packing records into sleeves is located on the other side of the edge trimmer 2, an oscillating table 7 carrying a record on a disc 5 to the edge trimmer whilst it carries a record on a disc 6 away from it, and vice versa.

Abstract: 1516248 Hydraulic brake systems CATERPILLAR TRACTOR CO 8 Sept 1976 [24 Nov 1975] 37196/76 Heading F2F A spring-applied brake is held off by hydraulic pressure transmitted from a pressure source through a line 12, a valve 18 and a brake line 20. The brake is applied by manually pulling valve stem 48 to the right so that fluid in the system can escape to a sump via port 30. The brake may also be released in an emergency, e.g. on failure of the hydraulic pressure source by further movement of the valve stem 48 to the right, so that the land 56 of the valve stem acts as a piston within bore 36 and pressurizes fluid in the brake line 20. The valve 18 is disposed below the level of the sump so that in the emergency mode leakage of fluid past the land 56 can be corrected by allowing it to move to the left, when the bore 36 will be refilled, and then pulling the valve stem 48 again to the right.

Title: Blocking Oscillator Circuit and Sweep System Using the same
IPC: H03K4/66
Filed: 1967-08-15
Abstract: 1,179,589. Transistor blocking oscillators. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 15 Aug., 1967 [23 Aug., 1966], No. 37442/67. Heading H3T. A blocking oscillator in which a capacitor C 6  charges through a resistor R 5  and the oscillator transistor T 4  whilst the transistor is conductive and discharges through a resistive path R 7 , R 8  when the transistor is blocked; includes an auxiliary circuit branch comprising a diode D 11  connected to the transistor input, and a capacitor C 17  connected between the output electrode of the transistor and the auxiliary branch for biasing the diode D 11  for conduction only during conduction of transistor T 4 , the auxiliary branch then passing a substantially stronger current I D  than that (I b ) required to hold the transistor saturated. Diode D 11  is rendered conductive simultaneously with transistor T 4  by a negative signal fed through capacitor C 17 . In the Specification it is shown that diode current I D  remains constant whilst base current I b  decreases until cut-off, and it is also shown that with I D  substantially greater than I b  and substantially constant, the mark and space times of the oscillator are independent of transistor characteristics and transformer turns ratio and hence small load variations. The repetition frequency may be adjusted by altering the resistance of path R 7 , R 8  or the potential to which it is connected (by contact 9). The output 3 of the oscillator may be used (Fig. 4, not shown) to provide the base current of a television line sweep transistor. It is also indicated in the Specification that, as a result of the emitter potential V e  being held constant by circuit R 15 , C 16 , the current supplied to the base of the sweep transistor remains substantially constant over a range of repetition frequencies, provided a certain formula for the turns ratio of transformer TR is obeyed. Thus the oscillator may be switched between television standards without affecting the performance of the sweep stage.

Abstract: 833,338. T.R. switches. BRITISH THOMSON-HOUSTON CO. Ltd. Feb. 8, 1957 [Dec. 30, 1955], No. 37446/55. Class 39(1). [Also in Group XL(b)] In a T.R. cell or pre-T.R. cell comprising a length of sealed waveguide of circular crosssection, the cell being adapted to be coupled to an adjacent waveguide system through respective slots situated at each end of the cell, said slots are angularly displaced with respect to each other to increase the pass-band of the cell. The T.R. cell shown inside and end view comprises a length of circular waveguide I closed by flanges 2 and 3 each containing a resonant slot 4 sealed by a glass window. The pass-band of the cell increases as the angle between the slots 4 in the flanges 2 and 3 is increased to a maximum of 45 degrees. A resonant structure 5 has opposed triangular projections forming a spark gap. The pass-band of the cell may be made variable-by arranging the structure 5 to be rotatable relative to the flanges 2 and 3. Alternatively one or more resonant irises similar to structure 5 may be introduced into the cell, and angular rotation of such structures will vary the pass-band. In a pre- T.R. cell the structure 5 is omitted.

Abstract: 1430514 Testing logic circuits INTERNATIONAL BUSINESS MACHINES CORP 28 Aug 1974 [6 Sept 1973] 37532/74 Heading G1U A logic circuit tester of the type in which a sequence of test words is applied by a system controller, Fig. 1 to the logic circuit device under test DUT, and the resulting output words are compared 12 with the expected output words (i.e. those that a perfect device would produce), is characterized in that for each word of the test sequence either (a) the voltage level representing each bit is assigned independently from each other bit at random from two levels, namely "Hi-one" and "Lo-one" if the bit is a one, and from two levels namely "Hi-zero" and "Lo-zero", if the bit is a zero, or (b) the voltage level representing each bit is varied independently of each other bit, randomly between two levels, namely the aforementioned Hi-one and Lo-one levels for one bits, and Hi-zero and Lo-zero for zero bits. As described, each bit of each test word is applied to an associated decode logic 3, which, in accordance with whether the bit is a one or a zero, decides which voltage level to assign to represent it. In the first embodiment, Fig. 3A, the level chosen is determined by gating a burnt of pulses 24 to a bi-stable 25, (the pulses being produced for example by an oscillator whose frequency is deliberately made to be unstable) and its resulting state determines whether a pair of Hi gates 28, 30 or a pair of Lo gates 29, 31 is opened to the incoming bit 21. In the second embodiment Fig. 5 (not shown), bi-stable 25 receives a continuous stream of random pulses, rather than a single burst, so that the pairs of Hi and Lo gates are continually being opened and closed.

Abstract: 1400419 Drilling and tapping assembly TELCO (GROUP MANAGEMENT) Ltd 15 June 1972 [11 Aug 1971] 37661/71 Headings B3C and B3N An assembly for drilling and tapping a hole in a workpiece 12 mounted in the collet chuck 11 of a lathe is, in use, mounted by casing 1 on lathe cross-slide 10. Initially, drive from, for example a flexible drive coupling see Fig. 1, is transmitted via shaft 17 and pinions 22 and 23 to drill 24 which is fed by the cross-slide to drill the hole. Shaft 17 also drives, via pinions 20, 21, rearward and forward gear and dog clutch members 28 and 33 freely rotatable on shaft 18 which carries tap 9, an axially slidable clutch member 38 connecting either member 28 or 33 to shaft 18 dependent on its position but being initially biased by spring 43, Fig. 2, to connect forward gear member 33 so that the tap is rotated in a withdrawal sense. After drilling, the cross-slide is retracted and supporting structure 75 for the drill 24, shaft 18 and associated parts is pivoted about the axis of the shaft 17 by means of fluid-pressure operated cylinder 45 actuating lever 46 so that the tap is brought to the working position. In so doing, a projecting lower end of a lever 49 mounted on the structure 75 engages cross-slide 10 and pushes a latch 41-connected to clutch member 38 via yoke 40-rearwardly so that gear and clutch member 28 is engaged and the tapping shaft 18 rotates in an insertion sense and is advanced by means of lead screw and nut arrangement 25, 26 on one end. When a predetermined depth of tap is reached an abutment body 48 of shaft 18 engages a plate 52, Figs. 2, 4, carrying a depth indicating rod 55 and a screw-threaded depth adjustment stem 53, which has an abutment 74, and movement of the plate causes abutment 74 to operate tripping lever 51, Fig. 2, to "trip" latch 41, which is pivoted to yoke 40, upwardly and out of engagement with lever 49 thereby allowing spring 43 to return the clutch member 38 to its forward position and to withdraw the tap 9 until clutch member 38 is carried out of engagement with member 33.
