Title: Improvements in or relating to machines for loading plastic explosives into containers and for like purposes
IPC: F42B33/00
Filed: 1947-02-03
Abstract: 631,256. Loading plastic explosives into containers. NITROGLYCERIN AKTIEBOLAGET. Feb. 3, 1947, No. 3150. Convention date, Feb. 1, 1946. [Class 9 (i)] Refers to machines in which plastic explosive is expelled by plunger through extrusion nozzles into containers as in U.S.A. Specification 1,245,528, and consists in providing cutting means in or adjacent the nozzles such as a string or strings rotatable in a plane perpendicular to the extruded material about an axis parallel to the longitudinal axis of the nozzles. A nozzle 1 is surrounded by a retractable, rotatable sleeve 2 carrying diametrically placed cross-wires or strings 3. Explosive is fed through the nozzle into a container until it reaches the required level, the feed is then stopped and the sleeve rotated, the strings 3 thereby cutting through the explosive. Instead of a separate sleeve, the nozzle may be rotatably mounted and carry the cross-wires. An apparatus with a plurality of nozzles may have all the cutting members simultaneously rotated by a toothed wheel geared to the individual supporting members. The cross-wires may be replaced by a single diametrically-placed wire or by three parallel wires one of which is placed diametrically.

Title: Improvements in suspension systems for vehicles
IPC: B60G11/00
Filed: 1960-01-28
Abstract: 930,087. Road vehicle suspensions. USTAV PRO VYZKUM MOTORVYCH VOZIDEL. Jan. 28, 1960 [Feb. 3, 1959], No. 3176/60. Class 108(2). A suspension system for a vehicle comprises a spring 1, Fig. 1, a stirrup 311 engaging one end of the spring and pivoting about an axis 60 on a sprung or unsprung part of the vehicle and means for pivoting the other end of the spring on the other part of the vehicle. The stirrup 3<SP>11</SP> is of inverted U-shape with the ends of the limbs pivoted at 60 to a similarly shaped bracket 6 secured by a bolt 63 to a longitudinal member 46 of the vehicle frame. The lower end of the spring bears against a member 3 pivoted at 4 on a link 7 which is in turn pivoted at 9 to the member 46 and connected to a rear axle 7<SP>11</SP>. A rod 61 riveted to the stirrup slidably engages a bore in the member 3. When the load on the suspension increases, the stirrup rotates anticlockwise about the axis 60 so that the moment of the spring about the pivot 9 increases very gradually. Fig. 4 shows a wishbone type of suspension in which a stirrup 311 is rotated clockwise about a pivotal connection 60 with a bracket 6a to give a gradually decreasing moment from the spring 1 with increasing deflection. A second spring 1<SP>1</SP> mounted in a stirrup 3<SP>1</SP> angularly adjustable by a rod 10 about a pivotal connection in the bracket 6a coaxial with a pin 4 gives a combined moment which increases with deflection. The rod 10 may be adjusted manually or automatically and the spring 1<SP>1</SP> normally remains in a fixed position during deflection of the suspension. Conical, variable pitch, rubber and pneumatic springs having non-linear characteristics may be used. In Figs. 6 and 7, a rear axle 7<SP>11</SP> is pivotally connected by a bolt 69 to a link 7 pivoted at 9 to a longitudinal member 46 of the vehicle frame and at 60b to a pair of elements 73 having arms 73a connected by a common pivot 32 to a rod 10 for manual or automatic control of the stiffness of the suspension. Further pivots 60a connect the elements 73 to a stirrup 3<SP>11</SP> which contains one or more springs 1<SP>11</SP> and is telescopically connected by a pin 61<SP>11</SP> to an abutment 3 pivotally mounted at 4<SP>11</SP> on the member 46. The Specification contains illustrations of the suspension characteristics.

Title: Improvements in or relating to record-card controlled calculating machines
IPC: G06F7/46
Filed: 1934-01-31
Abstract: 432,640. Statistical machines. BRITISH TABULATING MACHINE CO., Ltd., Victoria House, Vernon Place, Southampton Row, London. Jan. 31, 1934, No. 3211. Convention date, Feb. 1, 1933. [Class 106 (i)] Means for multiplying, adding, and subtracting.-In a record-card-controlled statistical machine for summing a multinominal expression, all the terms of the expression being punched in a single card, various terms and/or products of the terms in the expression are added or subtracted according to the presence or absence of special indications (" 11 " and " 12 " holes) on the card. The special holes are read by extra brushes 106, 107. Alternatively the actions initiated for each card by brushes 106, 107 reading,holes, may be initiated for a run of cards by closing manual switches 288, 287. The invention is illustrated as applied to a multiplying machine of the kind described in Specification 405,031 but having cyclecontrolling mechanism as described in Specification 358,105. With three terms A, B, and C punched on the cards, with switches 287, 288, Fig. 8e, open and with no special holes in the cards read by brushes 106, 107, the apparatus computes the expression A-(B+B.C). With switches 287, 288 closed, the signs in front of B and BC are according to the following table, the subtraction of the amount in one counter from the amount in another counter being by complementary addition. For the automatic action according to the invention the sign in front of each term B and BC is determined by brushes 106, 107, the circuits of which are timed so that brush 106 may read a " 11 " hole and brush 107 a " 12 " hole, if present. The effect if brush 106 or 107 reading a hole is equivalent respectively to closing switch 288 or 287. If desired one of switches 287, 288 may be closed for a run of cards and the automatic control may be only on the other circuit. The expressions covered by the general expressions AŒ(BŒC) and AŒ[BŒ(BD+C)] may also be computed. In completing the expression say A-(B+BC), (switches 287, 288 both open), the amount BC is transferred in direct form to the counter holding the term B and is transferred in complemental form to the counter holding the term A. For the expression say, A-(B-BC), switch 288 is closed (a brush 106 reads a " 11 " hole) and the circuits from the reading-out commutators are reversed so that the amount BC is now transferred in complemental form into the counter holding the term B and is transferred in direct form to the counter carrying the terms A. The final result and various terms may be punched in the card carrying the terms of the expression. Specifications 362,529, [Group VIII], 371,447 and 409,371, also are referred to.

Title: Acoustic surface-wave filter circuits
IPC: H03H3/08
Filed: 1976-01-28
Abstract: 1517056 Surface wave filter devices; variable selectivity circuits SONY CORP 28 Jan 1976 [30 Jan 1975] 03332/76 Headings H3U and H3Q A filter circuit comprising a surface wave filter device connected to an amplifier includes means for changing the bandwidth of the surface wave device and simultaneously changing the gain of the amplifier to compensate for the concomitant change in the insertion loss of the surface wave device. As shown in Fig. 4, outputs El, E2 of an amplifier 21 are connected to a surface wave filter device 31, which comprises input and output interdigital transducers 4, 5, Fig. 2. The bandwidth changing means is a switch S1 which, in the position shown in Figs. 4 and 2A, connects finger groups 7a, 7b, 7c to input terminal 8. Changing- over of switch S 1 narrows the bandwidth of device 31 by earthing finger groups 7b, see Fig. 2B. In the former postion, S1 connects transducer 4 to output El and, via resistor 46, to output E2; in its latter position Sl takes output E2 to earth so that the output impedance of amplifier 21 increases to compensate for the change in insertion loss of device 31. In an alternative arrangement switch contact c may be coupled to earth through a bypass capacitor. At the output 11 of device 31 a witch S2, which may be ganged with S1, controls he connection of finger group 10b of output transducer 5 and selectively short-circuits a resistor 48 to correspondingly vary the matching impedance. The filter circuit may comprise a plurality of filter devices 31-36 each with a respective amplifier 21-26. As shown devices 34-36 have fixed bandwidths, and devices 32, 33 have bandwidths which can be changed by switches S3-S6 which may be ganged with switches S1, S2 or independently operable. Amplifier 21 comprises common-connected transistors 42, 43 which are coupled to earth by a constant-current source 41 and whose collectors are connected through resistors 44, 45 to a voltage source Vcc. The circuit may be used in the I.F. stage of an F.M. receiver, in which case amplifier input terminal 27 receives a mixer circuit output and output 11 of device 36 is fed to an F.M. detector.

Filed: 1943-03-08
Abstract: 565,184. Angular bending. COWLIN & SON, Ltd., W., and HURLEY, R. E. March 8, 1943, No. 3759. [Class 83 (iv)] In an apparatus for bending tubes and rods of the kind having at least two co-operating parts with complementary shaping surfaces movable towards one another, a bending member pivoted on one of the co-operating parts is rocked on its pivot by means on the other co-operating part in timed relation with the movement of the movable part so as to cause it to perform a bending operation on the tube or rod additional to that effected by the co-operating parts. A tool of box construction to be placed on the bed of a press has a fixed tool 1 cooperating with a spring-returned tool 2 movable on guides thereon. On the part 1 is pivoted at 16 a lever 15, one limb of which is grooved to receive the tube &c. 17 and the other limb 151 of which is engaged by an element 18 on the part 2 so as to bend the tube against the side 51, 5<11> of the part 2 after it has first been bent between the edges 5, 4 of the parts 2, 1. The lever 15, which may be spring-returned, is not moved until the element engages the surface 151 at a point towards its pivot, so that the initial motion is rapid but diminishes as the element travels down the surface 15<1>. The other side of the tool may have shaping surfaces for bending the tube in a plane at right angles to the first bends. In another form, the stationary part 1 is provided with a shaping surface 31 and with the element 28 which operates a bending lever 25 pivoted at 26 to the spring-returned movable part 2 and bends one limb of the U-shaped tube 27 over the surface 30 on the upper part 2 after the surface 29 thereon has bent upwards the other limb of the tube by co-operation with the surface 31. The rate of rocking of the lever 25 is varied to adapt its motion to that of the part 2. The lever 25 is returned to initial position by a spring or by a cable or chain on maximum separation of parts 2, 1. The tool may' be provided on the other side with dies for bending the tube to U -shape. The limbs of the U are slightly twisted out of a common plane. Antifriction rolls may be provided at the ends of the element 28 and lever 25. In a further form, Fig. 6, a lever 35 provided with a channelled fibre block may be pivoted at 36 on the part 1 of the tool and operated by an element 38 on the movable part 2 so as to bend the tube against the side of the die block 32 carried by the part 2 after the latter has first forced the tube down into contact with the block on the lever 35. In another form, the movable part 2 has pivoted thereon at 46 a lever 45 provided with rollers 43 which run on a pair of spaced inclined straight or curved guides 48 surfaced with metal or other wear-resisting material to bend the tube round a former 50. The lever is restored to position by a spring 42. The wearing surfaces of the tool may be of compressed fibre whilst the bending lever and its operating element may be of metal, plastics or wood.
