Title: An improved method of and means for preparing poultry for the table
IPC: A22C21/06
Filed: 1929-03-23
Abstract: 326,037. Sandiford, A. March 23, 1929. Poultry, dressing. -A device for preparing poultry for the table consists of a base member 1 slotted at 1A to receive a leg of the bird, a lever 3 pivoted on the base, a rotary member 2 journaled coaxially with the lever 3 and having an end 2B shaped to co-operate with the end of the lever to grip the leg, a spring 2D connecting the lever 3 and the member 2 to maintain the gripping pressure, the components being aranged so that when the lever is moved in one direction, the member 2 is checked by the stop 20 and the jaws 2B open against the spring pressure to allow the leg to be inserted, and, when the lever is moved in the opposite direction, the member 2 moves therewith, the shin bone of the bird being broken and the foot, with the sinews attached, being drawn away from the leg. The base is shaped to give the slot 1A an inclination which assists in positioning the leg.

Title: Improvements in or relating to current regulating circuits
Inventor: DYKE JOHN RODGER
IPC: H05B39/04
Filed: 1961-03-15
Abstract: 994,425. Automatic light intensity control. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Feb. 22, 1962 [March 15, 1961], No.9464/61. Heading G3R. A lamp 1 is supplied with unsmoothed direct current from a rectifier 2, the lmap current being controlled by a series resistor 4 which may be short-circuited by a transistor T1. Light from the lamp 1 falls on a photo-voltaic cell 5 the output of which is applied to a transistor T2 together with an adjustable reference current obtained from an auxiliary supply 10, through Zener diode 6 and resistors 7, 8. This is arranged so that normally the ripple content of the photo-cell output causes the transistor T2 to conduct intermittently. This, through the intermediary of a transistor amplifier 17 causes transistor T1 to conduct for short periods at ripple frequency, but out of phase with the original ripple from rectifier 2 due to the time constant of the lamp 1. Changes in light intensity produce compensating changes in the length of time for which transistor T1 is conductive. It is stated that if the load is not a lamp, the current can be measured by a series resistor, and that the transistor T1 may be in shunt instead of in series with the load.

In a direct-resistance heating process the pipes follow each other in line through the heating zone and are temporarily joined by double-convex, double-conical, or cigar-shaped elements of good electrical and thermal conductivity which are held in place by deceleration of the pipes as they enter that zone, and are subsequently released as each pipe is accelerated away from that zone. As shown in Fig.1, a pipe passes at velocity V1 from zone "a" to zone "c" where it is decelerated to V2 and passes through contacts 5, 4. Joining element 2 is interposed between the leading and the next following pipe and remains in that position until the leading pipe reaches the zone "d" where it is accelerated to V3 causing the element to fall away; the latter is then returned to "a".
