Title: Improvements in or relating to the processing of animal material compositions
IPC: A23K3/00
Filed: 1971-04-19
Abstract: 1286778 Sterilisation STORD BARTZ INDUSTRI AS 19 April 1971 [27 April 1970] 27227/71 Heading A2D A process for the batch sterilisation of a water-containing animal material and the evaporation of the water content thereof comprises leading the composition through a space defined between inner and outer heating surfaces by rotating the former in a given direction, said inner surface representing a far larger proportion of the total heating surface than the stationary outer surface, arresting the passage of the composition by rotating the inner surface in the reverse direction thereby bringing about stirring of the composition. The composition is sterilised and its water content evaporated by heating, then expelled from the space by rotating the inner surface in its original direction. The process may be carried out in the apparatus shown in Fig. 1 wherein the animal material is fed via intakes 16 into a cylindrical housing 10. Within this housing there is positioned a rotating heating body 20 which consists of a hollow cylinder 23 having welded on its external surface, a series of hollow disc elements 26. To the peripheries of the hollow elements 26 there is welded a vane system 27 consisting of vanes 28 and 24 which system in the axial direction of the housing crosses one or more of the elements 26. The angular orientation of the vanes in respect to the longitudinal axis of housing 23 is such that during rotation of the housing in a given direction, the animal material is fed through and expelled from the apparatus whereas rotation in the reverse direction does not cause any longitudinal movement of the material but imparts a stirring action to the material. Steam, for sterilisation and evaporation purposes, is supplied to the apparatus through the hollow shaft journal 24a and into the interior of the disc-shaped elements 26. The process is particularly applicable to the treatment of butcher's offal, animal entrails, animal meat, feathers, blood and fish waste.

Abstract: 1359035 D.C.-D.C. converters; supply systems for photoflash apparatus WEST ELECTRIC CO Ltd 14 June 1971 27694/71 Headings H2F and H2H [Also in Divisions G2 and H3] In electronic photoflash apparatus comprising an oscillating circuit having a transformer 7 and a transistor 8, arranged as a D.C.-D.C. converter, a three-electrode switching device 1 is arranged to short-circuit the base/emitter path of transistor 8 in response to a signal on its control electrode derived from the primary side, so that the output voltage V2 is substantially independent of the supply voltage 6. As described, transistor 8 is made oscillating by feedback around transformer 7, the output from winding N2 being rectified at 10 and charges a capacitor 9 which is discharged through a triggered flash tube 11 under control of a circuit B. Capacitor 3 charges to a low voltage dependent on the output voltage V2. When the voltage Vc across capacitor 3 reaches a voltage dependent on the setting of potentiometer 2, thyristor 1 becomes conductive, short-circuiting the base/emitter path of transistor 8 and stopping oscillation. Thyristor 1 then becomes non- conductive and the oscillation restarts when capacitor 3 is sufficiently charged via resistor 4. In Fig. 3 (not shown) the gate of thyristor 1 is connected to a potentiometer capacitor arrangement supplied by rectifying the output of winding Nc. In Fig. 5 (not shown) the gate of thyristor 1 is fed from a potentiometer across the battery 6. In Fig. 13, thyristor 1 is replaced by a complementary pair of transistors 19, 20 having a diode 22 arranged to stabilize the triggering voltage. Indicating correct voltage in electronic photoflash apparatus.-In Fig. 1, an electroluminescent element 12 indicates when the transistor 8 is oscillating. In Fig. 15 (not shown) element 12 is replaced by a discharge lamp 24. In Fig. 16 (not shown) a Ga As luminescent diode in series with a further diode is connected across winding Nc. In Fig. 17 (not shown) the luminescent diode is connected in series with thyristor 1. In Fig. 20a (not shown) the luminescent diode is connected to the slider of a potentiometer across battery 6. In Fig. 24, the luminescent diode is connected in series with resistors across capacitor 3 and is used as a temperature compensator for thyristor 1.

Filed: 1927-10-20
Abstract: 304,631. Smith, W. S., and Mc- Lachlan, N. W. Oct. 20, 1927. Thermionic valve circuits.-The damping of an oscillatory circuit in a wireless receiver or the like is reduced by a negative - resistance device comprising a screened-grid valve. As shown in Fig. 2, the damping of an aerial circuit is reduced by variably coupling it to a tuned circuit 6, 7 connected between the anode and filament of a screen-grid valve 1. The inner grid 4 is maintained at a suitable low voltage, and the outer grid 3 has a higher voltage than the anode. An auxiliary screening-grid may be interposed between the screen-grid 3 and the anode. The degree of negative resistance applied to the aerial may be varied by adjusting its coupling to the circuit 6, 7, or by inserting a variable resistance in series or in shunt to the oscillatory circuit, or by varying the voltages of the electrodes. In a modification, a reaction coupling is provided between the aerial circuit and a tuned circuit connected to the inner grid 4.

[Class 80 (ii)] [Also in Group XXXVII] A switch particularly adapted for use in change-speed mechanism such as described in Specification 524,982 comprises a contact-carrying rocker 17 which is rocked about its axis 18 to bring its contact 23 momentarily into engagement with a fixed contact 24 when an actuating member 14 is rotated about its pivot 16 away from the position shown, the rocker remaining unmoved when the member 14 returns to its original position. The Figure shows two such switches operated respectively by counterclockwise and clockwise movements of the member 14 and a third switch may be arranged beneath one of the switches shown to be operated in a similar way after the member 14 and shaft 16 have been moved longitudinally downwards. The member 14 carries a V-shaped block 15 which engages an eye 26 on a spring strip secured to the rocker 17, first operating the rocker and then slipping by. A spring 19 biasses the rocker so that it normally bears against a stop 22. The contacts 23, 24 close the circuit to a coil which causes frictional engagement between the magnet and slidabfe dog clutch element preventing movement of the latter and of the actuating member 14 until synchronism is reached.
