Abstract: 1,113,993. A-D Converters. SPERRY RAND Ltd. 21 Oct., 1965 [1 Oct., 1964; 21 Oct., 1964], Nos. 40085/64 and 42912/64. Heading G4H. An applied input force causes deflection of a beam, this being detected at 18, 31 to produce an analogue signal which in turn causes clock pulses from a source 43 to be applied to the least significant counter 49 of a series 49, 51- 53, 50 or to an intermediate counter 52, depending on the magnitude of the deflection; and the counters operate relays 12 to vary the resistances 56 in circuit with a digital coil 36 until the force exerted by this coil restores the beam to its datum position. The analogue signal from 31 is applied directly to an analogue coil 34 so as to oppose the input force and reduce the deflection which occurs, the current flowing in this coil being reduced substantially to zero when balance is achieved by coil 36. Normally, with small deflections of the beam, only relay 32 operates to energize one of leads 41, 42 controlling, the direction of counting in accordance with the sense of the deflection, but if a large deflection occurs, relay 33 also operates to open gate 80 and close gate 48 whereby the clock pulses are applied to counter 52 so as to increase the rate at which the balancing force is built up. An indication of the magnitude of the input force is given at 54 when the balance condition is reached. Provision is made for preventing over-run at each end of the measuring range.

Title: Obturators, particularly for wedge breech mechanisms of guns
IPC: F41A3/74
Filed: 1969-08-12
Abstract: 1,273,036. Gas checks and obturators. FRANCE ARMED FORCES MINISTER OF. 12 Aug., 1969 [22 Aug., 1968], No. 40370/69. Heading F3C. A gun having a wedge breech mechanism is provided with a metal obturator defining an annular cavity into which the gases created by the gun will pass, the obturator being in two annular parts one defining the outer side and a lateral sealing side of the obturator and the other the inner side through which the gases will pass. The rear face of the barrel 1 is drilled to define a cavity housing the obturator 2, the annular parts 4, 5 of which are of hard metal, such as gun steel. Adjacent the rear face of the barrel 1 is a breech-wedge 3 which forms a seal with the obturator 2. The external part 4 is deformed radially and slides axially under the pressure of the gases accompanying the departure of a projectile. This part is of angle section, the side perpendicular to the axis of the barrel 1 bearing on the front face of the breech wedge 3 and its side parallel to the axis being in contact with the wall of the cavity formed in the barrel. The internal part 5, which acts as a spring having very slight compression, also has an angle section. Passages 6 in the inner wall of the part 5 allow the passage of gases to the interior of the obturator. In an alternative construction, the obturator is fitted into the wedge and the arrangement is reversed, that side of the external part 4 which is perpendicular to the axis being in the plane of the breech face, whilst the purpose of each of the parts remains unchanged. In both cases, the assembly is designed and dimensioned in such a way that, when the breech block is in the closed position, in the static state, the axial bearing positions are assured elastically.

Title: Improvements relating to preloading of timeswitches
IPC: G07F15/12
Filed: 1958-12-16
Abstract: 928,502. Time switches. S. R. SMITH. March 15, 1960 [Dec. 16, 1958], No. 40451/58. Class 38 (5). [Also in Group XVIII] An operating shaft 1 is geared to a shaft 40 to set the latter forwardly by distances corresponding to the value of inserted coins, as described in Specification 928,501 [Group XVIII], and a cam 140 on the shaft 1 initially sets a spring-loaded parallelogram lever system 102, 105, 104, 103 in readiness to close switch contacts 107, 108 for a timing motor which drives the shaft 40 back to zero position but actual closure of the contacts is delayed until the shaft 1 has completed a full revolution. In the starting position, a projection 115 on the lever 103 lies in a slot 152 in a timing cam 110 on the shaft 40 and a spring 111 holds the levers so that the levers 102 and 103, pivoting about a fixed point 100, engage stops 113 and 112. Rotation of the shaft 1 causes the cam 140 to press the lever 103 down and to raise the projection 115 from the slot 152, as shown in Fig. 3, and the shaft 1 also rotates the cam 110 by an amount corresponding to the value of the coin inserted; a projection 106 on lever 102 does nut, however, close the contacts 107, 108 at this point. When the shaft 1 has completed a revolution, the lever 103 is allowed to be pulled back against its stop 112 and, by a toggle action of the levers about the point of contact of the projection 115 with the cam 110, the lever 102 moves away from its stop so that the projection 106 closes the motor contacts 107, 108. The motor then returns the cam 110 to zero position and the lever system is restored to normal position when the projection 115 drops into the slot 152. During accumulation of time value by the insertion of further coins, the levers are in the Fig. 3 position and the motor contacts are open until the shaft 1 has completed a full revolution.

Abstract: 1,204,363. Stapling fibres. EASTMAN KODAK CO. 7 Sept., 1967 [8 Sept., 1966], No. 40963/67. Heading D1F. Elongate material e.g. continuous polyester filament tow, ribbon, tape, wire, film, is cut into predetermined short e.g. staple fibre, lengths by winding convolutions of the material around knife-edges and forcing it onto the edges. Spaced knife-edges may form a closed e.g. circular, geometric figure which is rotated as a unit and the material is pressed e.g. by an adjustably positioned roller bearing on the outermost convolution, onto successive single edges. As shown, incoming tow, flattened into a tape and tensioned by guides 60 and shaped or limited in width by edge guides 66, is fed onto a rotary cutting wheel or reel 18 and wrapped therearound between a mounting disc 20 and a mounting ring (22) seating on the edges of replaceable, adjustable and perhaps reversible, blades 30. As the winding continues, pressure develops between a pressure roller 42 and the convoluted material sufficiently to sever the latter. The cut tow &c is removed by air jet, suction or gravity and collected into a funnel 72. The blades may project from the wheel by different amounts e.g. so that division and then sub-division of the material occurs, and the spacing thereof may be irregular or varied to product cut portions of different lengths. The peripheries of pressure roller and cutting reel may be complementarily angled, or the roller may carry, or the blades form, material-confining flanges, Figs. 5-7 (not shown).

Abstract: 1,058,149. Sorting parcels. SOMEPOST. Oct. 9, 1964, No. 41304/64. Heading B8A. A parcel sorting machine comprises an endless belt 3 and a memory device 5 for temporarily storing parcel addresses and controlling air blast nozzles 35, 36 to propel parcels (not shown) from the belt 3 into shoots 7. An operator seated on a chair 22 takes a parcel from a shoot 19, depresses the keyset 21 to a code corresponding to the address on the parcel and places the parcel on the belt 3. Two cyclically operated half-gates 23, 23<SP>1</SP> hold the parcel back until it can be released in synchronism with the memory device 5. On its path to the shoots 7 the parcel passes three photo-electric barriers 27, 28; 29, 30; 31, 32. Carrier 29, 30 sets off the beginning of the cycle of the memory device 5 while barriers 27, 28 and 31, 32, which lie on either side of barrier 29, 30 detect whether the parcel is short or long. If the parcel is long barriers 27, 28 and 31, 32 are broken simultaneously and a make-up jet from the nozzle 36, as well as a normal jet from the nozzle 35, is brought into operation. This extra jet is also brought into operation if the parcel is weighty-as determined by a balance 33 under an unsupported part of the belt 3. The construction of the memory device 5 relates the time of travel of the parcel in relation to an address and comprises a rubbercoated drum 61 driven from the conveyer belt 3 by a chain 6. Metal balls 62 are injected into grooves 60 of the drum 61 by relay injectors 59 and actuate reader heads 63 set at predetermined azimuths to control electric valves 68 associated with the air blast nozzles 35, 36. As shown in Fig. 2, the working orifice of each nozzle 35 is divided into two parts 72, 73 by a partition 74 adjustable at 75 so that the jet is arranged to lift the parcel from the belt 3 as it blows it sideways into the shoot 7. The nozzles 36 are similarly constructed and may be supplied with air at a different pressure.

A machine for issuing trading stamps has two rolls 16, 70 of five- and one-stamp width, respectively. The value of the stamps to be issued is set up by keys 108, 106, Fig. 3, corresponding to 5/- and 6d. multiples. The selected key 108 partially discharges capacitor 180 to set binary cascade counter 111-114 through a diode matrix 184 according to the 5/- multiple. Solenoid 48, Figs. 2 and 4, energizes to release a clamp 52, 53 on the five-stamp strip 16 and simultaneously to lift roller 20 so that the strip is fed by drive roller 30. As each line of perforations passes a light 62 a photo-multiplier 64 reverses a flip-flop 248. Alternate reversals energize a magnet 65 to advance a tens counter 66 and pulses terminal 162 to reduce the count in cascade counter 111-114 by one. When the cascade counter reaches zero solenoid 48 releases to stop the feed and capacitor 180 recharges so that a 6d. multiple key 106 may be operated if required. The operation in this case uses light 95 and omits flip-flop 248 so that magnet 100 responds to every line of perforations to advance units counter 101. The machine stops if either of lamps 62, 95 fails.
