Title: Method and apparatus for supplying a mouldable substance adapted for freezing to freezing pockets
IPC: A23G9/28
Filed: 1957-04-29
Abstract: 858,291. Moulding ice-cream. BRODRENE GRAM A.S. April 29, 1957 [May 3, 1956], No. 13560/57. Class 87(2). Measured amounts of a mouldable substance, such as an ice-cream mixture, applied under pressure to a number of measuring chambers located side by side in a common housing and each comprising a pressure member located therein and a bottom opening, are discharged by maintaining the pressure members stationary while the chambers are elevated. The mixture is fed from a pre-freezing device via a pressure controlling valve and conduit 8, to distributing channels 31, 32 formed in an airtight top member 30 which extends lengthwise of a cylindrical drum 16 rotatably supported about a horizontal axis in a housing 17, 18 of a filling apparatus, and having a number of diametrical openended measuring chambers 21. The chambers 21 communicate through openings 24 with spouts 25 extending downwardly from housing 17, 18, and a piston 22 is loosely disposed in each chamber 21. The housing 17, 18 is adapted to be raised or lowered on a post 12. In the raised position, said mixture from the channels 31, 32 enters and is distributed in separate sections of each measuring chamber via inlets 23, 23 1 ; the pistons being at the lowermost part of each chamber. The spouts 25 are then vertically aligned above freezing pockets in a table by a stepwise angular movement of said rotatable table and are then completely lowered into said pockets, Fig. 4 (not shown). Drum 16 is then rotated through 180 degrees. A number of vertical rods 54 extend from a member 35 supported on the post 12 and through borings in the member 30 ; there being one rod above each chamber 21. Said members 34, 34 partake in said lowering only until the rods are located just outside the drum circumference. After said rotation the drum is raised and the pistons are held stationary by the rods 34 until the chambers 21 are discharged. Specification 668,622 is referred to.

Title: Facsimile printing systems
IPC: H04N1/16
Filed: 1972-03-23
Abstract: 1387434 Copying by scanning POTTER INSTRUMENT CO Inc 23 March 1972 [23 April 1971] 13643/72 Heading H4F A facsimile scanner 13 comprises a reciprocal scanning bar carrying a plurality (as described, twelve) of photo-cells aligned parallel to the line scanning direction, the printer 11 having a corresponding number of hammer blades 21 co-operating with a helical bar 19 on a rotatable drum 15, each photo-cell being connected via a respective AND gate 33 and OR gate 27 to one of the hammer firing circuits 29. A second reciprocal scanning bar having a like plurality of photo-cells may be included, each scanning bar scanning alternate lines of a document to be copied and being driven by a respective cam so as to move linearly during scanning. A transducer 35 viewing a tone wheel 37 rotated with drum 15 produces an output pulse on channel 41 for each revolution of drum 15 and an output pulse on channel 38 each time the intersection between each blade 21 and bar 19 passes through a dot print position. The output pulses on channels 39 and 41 are fed to scanner 13 to synchronize its operation, the pulses on channel 39 being fed to a frequency comparator (131, Fig. 10, not shown) and the pulses on channel 41 being fed to a phase comparator (133), the frequency and phase comparators also receiving respective signals from transducers viewing tone wheels rotated by the motor driving the scanning bars, the motor speed being controlled by the outputs of the frequency and phase comparators. The document being copied and the printed sheet may both be moved continuously in which case the scanning bars move in a skewed manner so as to scan, on the document, at right angles to the direction of document feed, the hammer blades 21 being similarly skewed. The pulses on channel 39 are also supplied to AND gates 33 so that printing only takes place at dot print position. Non-linear amplifiers (110, Fig. 11, not shown) may be included between scanner 13 and printer 11. A circuit 25, synchronized by the pulses on channels 39 and 41 may produce signals to print alphanumeric characters in addition to the facsimile copy.

Title: Electric vehicle drive systems
IPC: H01H9/54
Filed: 1972-03-23
Abstract: 1343256 Control of D.C. motors LINDE AG 23 March 1972 [8 April 1971] 13732/72 Heading H2J [Also in Division H3]  In a drive system for electric vehicle motors, the connection of each motor in different configurations is effected by a plurality of cascaded delay circuits each comprising a thyristor Th 1 , Th2 ... , a unijunction transistor n1, n11 ..., a potential divider circuit r20, r30, r12, r13 ... to which one base of the unijunction is connected and a tuning circuit r10, k1, r11, k11... connected to the emitter of the unijunction, the thyristor being connected in series with a contactor C1, C2 ... and the timing and potential divider circuit of the succeeding delay circuit so the operation of the thyristors is sequential with delays between each thyristor operating. The contacts of each contactor C1, C2 ... operate sequentially to control two split series field motors m1, m2 (Fig. 2) so that resistors r1, r2, r3 are successively cut out to leave the motors in series, after which the motors are connected in - parallel each with a series resistor which finally is also cut out. Thus the motor speed increases at a predetermined rate no faster than that set by the delays. This protects the motor if the accelerator pedal, which successively closes switches b2-b6, is depressed too quickly. A further switch b51 may be connected to the steering to limit the maximum speed when turning by connecting the motors in series. This also permits the inside and outside wheels to rotate at different speeds. Resistors r26, r36 hold thyristors Th2, Th3 on when fired so there is no delay when switching from series to parallel connection of motors.
