Title: Sheet feeding mechanism
Inventor: BYRNE JAMES PATRICK
IPC: B65H3/08
Filed: 1970-04-01
Abstract: 1,259,746. Feeding sheets. T. C. THOMPSON & SON Ltd. 3 Aug., 1970 [1 April, 1970], No. 15360/70. Heading B8R. A device for separating sheets from a pile comprises suction cups 8 mounted for movement in a first direction to lift the sheet from the pile and then in a second direction to forward the sheets to take-off rollers 21. The movement is brought about by continuously rotating cam 18 which acts on cam follower 17, causing lever 11 to move as permitted by pin 13 and slot 12. When the rear edge of a sheet has been lifted, a clamping member 23 is arranged to engage the remainder of the pile, Fig. 2A, and direct a jet of air beneath the lifted sheet. The separated sheets are forwarded in overlapping formation on to table 20 where they are engaged by endless tapes.

Patent GB-229172-A (GB)
Title: Improvements in or relating to apparatus for removing fat from intestines
IPC: A22C17/16
Filed: 1924-06-26
Abstract: 229,172. Soc. Anon. Fabre et Cie. May 15, 1924, [Convention date]. Intestines, cleaning.-In a machine for removing the fat from intestines, of the type wherein the intestines pass over a mandrel having an expansible portion which stretches and flattens the intestines and presents the fat layer to a knife, the expansible portions slide laterally and form, with a central portion, a flat continuous surface adjacent to the knife edge. The mandrel comprises a curved portion 3 which enters the intestines and guides them to a central portion 4 to which the spring-pressed expansible members 5 are pivoted, portions 7, 8 at right angles to one another forming shoulders 9, and rigid and flexible members 10, 11 extending from the portion 8. The cranked portions 21 of the members 5 slide in a. groove 22 and form, with the surface 6, a flat continuous surface. The mandrel is supported as shown in Fig. 1, by rollers 14, 15, 17. The roller 15 is resiliently and displaceably mounted and with the tappet 16 keeps the intestine in the correct position relatively to the disc knife 12. The rollers 17 engage under the shoulders 9 and prevent side movement. The intestines are drawn over the mandrel by interengaging, tapered, fluted, rubber feeding-rollers 13 one of which is resiliently mounted and flexible scraping strips mounted on drums 18 remove any fat still on the intestines. The rollers 13 and drums 18 serve also to steady the mandrel. By providing more than one extensible portion and co-operating portions on a mandrel, intestines having fat upon their entire surfaces may be treated.

Patent GB-797629-A (GB)
Title: Temperature control in fluidized roasting
IPC: C22B1/10
Filed: 1956-05-18
Abstract: The temperature of fluidized exothermic roasting processes is controlled by absorbing a major portion of the excess heat with indirect heat exchange elements such as steam coils permanently in contact with the bed and the remainder directly e.g. by evaporation of a cooling liquid introduced into the bed or by blowing air on to or into the bed.  In the case of sulphidic materials such as iron pyrites which yield sulphur dioxide, substance such as sulphuric pickling liquor which yields sulphur dioxide endothermically is preferably employed.

Title: Improvements in or relating to liquid cooled electric motors and control gear therefor
Inventor: ANDERSON JAMES
IPC: H02K9/24
Filed: 1957-05-16
Abstract: 888,291. Electric motors. ANDERSON, BOYES & CO. Ltd. May 13, 1958 [May 16, 1957], No. 15542/57. Class 35. [Also in Group XXXVII] A liquid-cooled electric motor 5 is controlled by a contactor, not shown, having in its control circuit 1 control gear which includes two parallel circuits 14, 16, flow switch means 15 sensitive to the rate of flow of motor cooling liquid and operable to close one, 16, of the two circuits when the rate exceeds a predetermined value, and relay means 12, 13 sensitive to the motor operating current and operable to close the other, 14, of the two circuits when the current is below a predetermined value. This arrangement provides that since the relay contacts 13 would be open at high motor currents the motor cannot be operated at high loads unless the cooling liquid flow is adequate to close switch contacts 15, but that on the other hand, by the relay contacts 13 being normally closed, operation is permitted at low loads for which no liquid flow is necessary, e.g. when equipment such as mining equipment driven by the motor is being moved from one place to another. The relay coil 12 may be serially connected in one of the A.C. power lines 2 . . . 4 to the motor or, as shown, connected to a current transformer 9, 10 in said line, and may be operated on D.C. by the addition of a half- or full-wave rectifier 11. A control switch 6 embodies additional contacts 7 linked to a time delay mechanism 8 to permit starting up the motor even though the motor starting current surge operates relay 12, 13 to re-open the contactor control circuit.

Title: Improvements in or relating to circuits for charging or discharging condensers
IPC: H03K4/12
Filed: 1947-06-13
Abstract: 642,910. Electricity supply. PHILIPS LAMPS, Ltd. June 13, 1947, No. 15629. Convention date, June 17, 1946. [Class 38 (iv)] [Also in Group XL (c)] Condenser arrangements.-In order to minimize the dissipation of energy in charging or discharging a condenser, the latter is connected through a coil coupled with a further coil connected to an energy accumulator, e.g. the charging source, through a reverse-connected rectifier which becomes conductive when the charge or discharge current approaches its maximum value at the end of a quarter period of the circuit, whereupon the energy stored in the magnetic field of the coils is fed to the accumulator after the abrupt cessation of the charging current. Fig. 1 shows a charging circuit wherein coil 5 is wound so that the rectifier 6 remains non-conductive when the switch is closed and until the voltage across coil 5 is sufficient to overcome the source voltage 4. In an alternative arrangement (Fig. 3, not shown) the branch circuit, consisting of coil 5 and rectifier 6, is shunted across the condenser 1. In a discharging circuit (Fig. 5, not shown) the condenser is discharged through a coil which is coupled with a further coil connected to an accumulator through a reverse-connected rectifier. In a charge/discharge circuit (see Group XL (c)) for obtaining a saw-tooth voltage providing a short fly-back time, and suitable for television purposes, the condenser, charged through a resistance, discharges into the coil through a gas-filled valve when the condenser voltage attains a predetermined value, and a further coil coupled with former coil returns the energy to the source through a reverseconnected rectifier.

Abstract: 168,987. Bates, A., and British United Shoe Machinery Co., Ltd. June 10, 1920. Link-work.-In an upper pulling machine for boots and shoes of the kind described in Specification 14453/97, [Class 17, Boots &c.], means are employed to vary the speed of revolution of the cam shaft at different points in each revolution. In the form of mechanism described the cam shaft is in two parts 2, 4, the part 2 being driven at uniform speed and the part 4 carrying the operating cams. An arm 6 fixed to the shaft 2 carries a pin 8 on which is rotatably mounted a block 10 adapted to enter a slot 12 in the bell-crank lever 14, which is pivoted to an arm 18 fast on the shaft 4. The lever 14 carries a cam-roll 20 spring held to the edge of a stationary cam 24 of irregular shape. When the roll 20 contacts with parts of the cam 24 concentric with the cam-shaft the arm 18 and shaft 4 will rotate at the same speed as the shaft 2, but parts of the cam 24 inclined away from or towards the cam-shaft cause a lag or acceleration in the shaft 4.
