Title: Improvements in apparatus for cutting open, cleaning and removing backbones from fish
IPC: A22C25/00
Filed: 1929-01-15
Abstract: 320,576. Baader, R. Jan. 15, 1929. Fish, dressing.-A machine for dressing fish is of the general arrangement described in Specification 188,432 and comprises a double disc 2 having a groove in which the backs of the fishes lie and tools arranged around the disc for effecting the various operations. The belly is cut open by two disc knives 4, 5, Fig. 9, the tail portion is cut by a disc knife 6, and the back skin is removed by a rotary member 15 having radial blades with fluted or toothed edges which penetrate into the belly cavity whilst two yielding discs 16, 17, Fig. 11, hold the sides of the fish against the blades. The fishes then pass to a pivoted spring-presed plough-like knife 20 having two cutting edges, Fig. 12, one of which engages on each side of the backbone, and thence to disc knives 21, 22, Fig. 13, which are set at an angle to out beneath the backbone and remove it from the fish. The fish is finally cut into two fillets by a disc knife 32. In operation, the tail of the fish is gripped by means on the disc 2 and is thus removed from the frame 33. The back is pressed against the groove in the disc 2 by a longitudinally grooved member 13, Fig. 9, which, being mounted with the knives 4, 5, on the spring-returned swinging arm 8, positions the knives to remove a constant depth from the belly. The guide 14, also on the arm 8, positions the fish whilst it is fed to the knife 6. After passing the member 15, the fishes encounter the knife 20 which is controlled by a roller 24 engaging a cam on the disc 2 whereby the knife is raised for the passage of the tail of the fish in which a short length of backbone is retained. The depth of the cut of the knife 20 is controlled by a member 2 which slides along the backbone and adjustment on the knife is permitted by a screw 25. The cutting edge of the knife 20 may be serrated. The knife is kept clean by a wiper 28 on a rod 27 which is reciprocated by an arm 29 actuated by a cam on the disc 2. The knife 20 slides under the rib bones and by a wedge action removes them from the flesh. The knives 21, 22 are journaled in a stationary bracket 30.

Title: Stabilised frequency synthesisers
IPC: H03L7/20
Filed: 1962-01-16
Abstract: 955,300. Automatic frequency control systems. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Jan. 16, 1962 [March 23, 1961], No. 1594/62. Heading H3A. In a key controlled decade frequency synthesizer with preliminary adjustment by a capacitor of the oscillator frequency to a preselected value and then fine control by an A.F.C. voltage, the oscillator frequency is swept by the sawtooth voltage output of a motor-driven potentiometer applied to a reactance tube 7 until the frequency is approximately correct, whereupon the motor 28 stops and a previously short-circuited output V 1  of the phase discriminator 14 then added to the potentiometer output V 0  and both conjointly applied to the reactance tube 7. The sweep motor stops when conjointly (1) there is output # 3  from a decade filter set 31 receiving frequency reduced signals from the oscillator 7 and (2) absence of lowfrequency output from a filter 36 receiving from a mixer 37 oscillations of same low frequency f 2  as the output of the phase discriminator 14, this arising when # 2  is less than 400 c/s. Expressed logically, the motor stops when #F 2 .F 3  =0, i.e. when #F 2 .F 3 =1, where F 3  is rectified output of f 3  and #F 2  denotes absence of output of rectified f 2  from an inverter circuit 26, the product #F 2 .F 3  being formed in an AND circuit 25. An OR circuit 22 is energized from a capacitor 24 for about 5 sees. on setting up the required frequency, thus ensuring the search motor 28 is through a relay 27 always started. This relay 27 through contact b also disables attenuator 32 so that the search control sensitivity is increased until synchronism is reached, whereupon transients, due to attenuator 32, have little effect in recommencing the search motor 28. Relay 27, after a short time due to network 33, then operates relay 34 which shortcircuits output V 1  of the discriminator 14 (so that only V 0  is applied to the reactance tube 7) and by contact d removes f 0  as input to the phase discriminator. In a modification the search motor 28 is driven from an OR circuit energized by # 2  (rectified) and by rectified f 3  through an inverter circuit, and the motor stops only when F 2 +#F 3 =0, i.e. absence of # 2  and presence of f 3  at the same time. The system may be applied to single sideband receivers. Specification 912,607 is referred to.
