Title: Improvements in or relating to impedance measuring and controlling circuit arrangements
IPC: G01N27/02
Filed: 1963-12-24
Abstract: 1,010,674. Automatic control systems. PHILIPS ELECTRIC & ASSOCIATED INDUSTRIES Ltd. Dec. 24, 1963 [Dec. 27,1962 ], No. 50951/63. Heading G3R. [Also in Divisions G1 and H3] Circuit arrangement measuring and controlling the ratio between two impedances are connected in series with an A.C. source and with the output impedance of an amplifier, in such manner that negative feedback is provided across the amplifier; one of the impedances being connected in the amplifier input circuit and the voltage amplification of the amplifier being unity. In Fig. 1 an A.C. source energizes the primary of transformer 2 whose secondary is centre tapped to the input of amplifier 5 whose output energizes the primary of transformer 6. Resistors 3 and 4, whose ratio is to be determined, are series connected to change over switch 7 selecting the lower terminal or the centre tap of the secondary, and to the lower end of the secondary of transformer 6 whose upper end is connected to the upper end of the secondary of transformer 2; the function of the resistors being earthed. The voltage across the secondary of transformer 6 is arranged to be equal and opposite to the voltage at the amplifier input, and the amplifier may be a cathode follower or emitter follower. It is shown by mathematics that E 1  = 1 - R 1 /R 2  E 0  where E 1  is the voltage across the output transformer secondary, E 0  is that across the input transformer secondary and R 1 , R 2  are the values of resistors 3, 4. Also that E 1  = R 1 /R 2  E 0  with switch 7 in its upper position. The requisite voltage may be indicated directly by a measuring instrument or vacuum tube voltmeter, or may be employed to operate a control system, e.g. for an electrolytic process in which one of the resistance values depends on the conductivity of an electrolyte and the other is a reference value, which restores the resistance difference and the control voltage to zero. A procedure for compensating circuit errors is described.

Abstract: 1,163,908. Printing device; addressing machine. PITNEY-BOWES Inc. 15 Nov., 1966 [24 Nov., 1965], No. 51151/66. Headings B6C and B6D. A printing device comprises a base with support means for a printing plate; a carriage mounted for reciprocating and pivotal movement over the plate; an inking and impression roller supported in the carriage; and control means for lowering the roller into contact with a sheet covering the printing plate as the carriage moves across the base. General arrangement.-An addressing machine, Figs. 1 and 2, comprises a base 2 supporting a platen 124 for a printing plate 151; a carriage 12 is mounted to reciprocate along and pivot about a slide-rod 10 under the control of a guide roller 72 engaging a guide-rod 70 which is provided with two notches 108, 110 having inclined cam surfaces 118 so that at the limit of the traverse of the carriage, guide roller 72 enters one of the notches and lifts the carriage away from the base. The carriage supports an eccentrically mounted print roller 14 which is inked by means of an internal resilient ink-retaining member (60), Fig. 4 (not shown); the extent to which the print roller projects beneath the arm 22 of carriage 12 is adjustable since the shaft (44), Fig. 7 (not shown), of roller 14 is eccentric with respect to its extension pieces (42), (56) which are mounted in bearings on the arm 22. Plate latching.-The base 2 is formed with a longitudinal groove 122 in which is secured a flat platen 124 with tapered ends (126), Fig. 8 (not shown), notched at 128 to provide access to latch plates 130 which are pivoted at 132 under the action of compression springs (136) to latch a printing plate 151 in position. Guide plates 148, 150 limit upward movement of a printing plate, and a movable dog (156) tends to hold a printing plate against the latch plates 130. Inking-roller drive.-The print roller 14 is preferably arranged to be positively driven over the printing plate during traverse of the carriage, Figs. 9-11 (not shown). A flexible cable (206) attached to brackets (208, 210) in side plates 6, 8 is sufficiently taut as to rotate a pulley (176) when the carriage 12 is manually traversed in either direction along slide-rod 10; the pulley (176) is geared to the shaft (44) of the print roller. The inked print roller may be replaced by a plain roller impressing on carbon paper.

Title: A loading and unloading device for bulky articles
IPC: B60P1/64
Filed: 1967-11-10
Abstract: 1,204,005. Container traffic vehicle loading. TEWI-PAT ANSTALT. 10 Nov., 1967 [5 May, 1967], No. 51187/67. Heading B8Q.  A vehicle load platform 3 has at each end a tubular support or jib 5 pivotally mounted on the medial plane. Pistons 6, 7 extend between a bearing-plate 11 at the top of the jib and shoes 13, 14 slidable on supporting bars 8, 9 pivoted on the edges of the platform. The free ends of the bars carry pivotally mounted supporting shoes 15, 16. To unload the platform the pistons on one side are extended to pivot the corresponding supporting bars until their shoes engage the ground while the other bars are retained locked in their vertical position and thus support the vehicle on the side unloading is to occur. With the load secured to or between the bearing members 11 the other pistons are now extended to swing the load in a circular path about the ground-engaged shoes until it is free of the side of the vehicle when the pistons on that side are retracted to lower the load to the ground.

Filed: 1965-12-03
Abstract: 1,131,636. Two-part couplings. EMPIRE PRODUCTS Inc. 3 Dec., 1965, No. 51507/65. Heading H2E. In a single-pole plug and socket electric connector, in order to improve the connection, pressure is exerted on the plug contact member 26 by the socket contact member 25 through the relative rotation of the two parts whereby a pin 142 of the socket engages in a cam groove (60) (Fig. 6, not shown) of the plug contact element 26, such rotation being controlled by a ratchet mechanism in which a locking tooth 76 of the plug engages ratchet teeth 150 of the socket. The tooth 76 forms part of a locking member (67) which is held in a groove (65) over a spring (81) by a snap ring (86). To disengage the tooth 76, the rubber insulating body of the plug has a thin flexible portion 90 with a plastic insert 93, so that pressure applied from outside to this portion pushes the locking member against the spring 81, the locking member pivoting about an edge 72 and so disengaging the ratchet teeth 150. To allow for varying degrees of resilience, the bifurcated plug pin may have a set screw 54 and to prevent the rotation of the contact elements 25, 26 within their housings each has a pin 102 or 124 which engage slots in rigid rings 95 or 120 moulded into the rubber housing. Cable ends may be attached to the connector parts by crimping them in soft metal cylindrical parts 45 and 115 connected to the contact members 25, 26, or alternatively the cable may be soldered directly to the members 25, 26. The connector housing 20 and 21 may be suitably shaped at 40 and 131 to co-operate upon engagement of the two contact elements so as to form a fluid-tight protective seal. In a modification (Fig. 9, not shown) the locking member pivots about a pin (185) and may be operated by the rod (192), a pin (218) and a rubber membrane (217). In a further modification (Fig. 17, not shown) the socket housing is mounted on a panel for attaching to a board, the socket contact element having a screw-threaded extension by which it may be attached to a cable (259).

Title: Apparatus for dividing dough and like materials
Inventor: BAKER DONALD ERNEST
IPC: A21C5/00
Filed: 1964-12-30
Abstract: 1,099,347. Moulding plastic substances &c. E. T. OAKES CORPORATION. Dec. 21, 1965 [Dec. 30, 1964], No. 52868/64. Heading B5A. In apparatus for dividing a continuous stream of dough e.g. cake batter, or soft plastics material into pieces which may be fed directly into tins or for passing through conventional hander-up, interproof and moulding equipment, the dough stream is delivered from a nozzle 1 into either one of a pair of cylinders 5, 7, alternately presented thereto and provided with displaceable pistons 2, 8, whilst a divided dough piece is simultaneously being dscharged from the other cylinder. The cylinders 5, 7 are mounted in a member 9 which is reciprocated by a cylinder 13 actuated by means responsive to a microswitch 4 or 15, operated by a spring loaded floating carriage 3 or 11 when contacted, via an adjustable stop 17 or 18, by a collar 10 on the descending piston 2 or 8, and preferably also responsive to a second microswitch 12 or 16 respectively in series therewith which is operated by the ascending piston 8 or 2 so that both microswitches are preferably actuated before the cylinders 5, 7 are moved. A changeover valve 6 may also be actuated by the means for driving the cylinder 13 whereby the cylinders 5 and 7 are alternately connected to atmosphere or to an air reservoir 14 to effect movement of the pistons 2 or 8. Adjustable valves 18, 19 in the exhaust connections from the valve 6 control the pressure of the dough required to displace the pistons 2 or 8. The pressure air from reservoir 14 may carry a fine spray of light edible mineral oil to lubricate the cylinders and to facilitate release of dough therefrom. The valve 6 may alternately be actuated separately from the cylinder 13 by a timing device, by a separate pair of microswitches or by movement of the slides 9. In an alternative construction the pistons 2, 8 are actuated by edible mineral oil instead of air utilizing the changeover valve 6 in conjunction with a pump or, alternatively, the change over valve may be dispensed with each cylinder 5 or 7 connected to the bottom of a separate pressure tank in which a constant air pressure is maintained. The pistons 2, 8 may also be coupled mechanically or hydraulically for simultaneous movement in opposite directions. The floating carriages 3, 11 and the microswitches may be replaced by electrical contacts which may be adjustably mounted. In an alternative construction a single microswitch may be operated by either of the filled cylinders to actuate the cylinder 13.

Abstract: 1292596 Regulating I. C. engines JOSEPH LUCAS (INDUSTRIES) Ltd 22 Jan 1970 [8 Nov 1968] 53034/68 Heading F1B In an I.C. engine petrol injection and air supply system having a shuttle-type fuel metering pump 10 provided with an adjustable stop 11, and having an air intake passage 28 provided with the engine throtle valve 40 and a upstream pivoted disc 30, a bimetallic coil 35 responsive to engine temperature, e.g. of the engine exhaust system, when the engine is cold, biases the disc 30 towards its closed position via levers 34, 36, 32 and torsion spring 33 and opens the throtle valve 40 from its normal slow running position vialevers 34, 37 and pivoted cam 38. With the disc 30 and valve 40 in these positions (as shown) the pressure difference across valve 40 is minimal thereby causing diaphragm assembly 18 to move cam follower 15 along track 23 in a direction which causes the stop 11 to move to an overfuelling position. As the engine warms up the closing bias on the disc 30 is reduced so that the latter has less effect on the air flow resulting in progressive increase in the pressure difference across the valve 40 and consequent progressive reduction of the overfuelling. When the engine starter is operated with the engine cold, a solenoid 26 connected to the starter solenoid (not shown) is energized and thereby rotates the track 23 about pivot 24 to provide extra fuel. During warm starting, however, the solenoid 26 is isolated by a microswitch 46.

The stripper 5 is actuated by a power unit 8 through links 12, and a switch 11 operated by cams 9 on a disc 10 fixed to the fly 3 is connected to and controls the unit 8 so that the unit can operate to lift the stripper only just before a sheet is about to strike the stripper. A sensing device is provided to detect a spoilt copy and transmit an operating signal to the unit 8. When the stripper 5 is lifted, an endless conveyer band 13 diverts the sheet from the fly and co-operates with another band 14 to forward the sheet to the receiver 15. The switch 11 may be adjusted so that a predetermined number of sheets may be diverted to the receiver 15.
