Abstract: 840,969. Fish, conveying. BAADER, R. G. T. Aug. 10, 1956 [Aug. 10, 1955], No. 24610/56. Class 28 (2). A headed fish, e.g. a cod, is pushed from a tiltable trough 5, by hand or mechanically over a spike 2 to top surface 6 of which is curved to bear against the back-bone 8, and the pointed end 3 is curved to finally enter the vent whereby the fish is tilted as in Fig. 4 as the spike conveys it against a belly-slitting knife 7. The underside of the spike 2 is of inverted U-shape, Fig. 6, and is inserted in the belly which still contains the guts. The spike 2 merges into wing guides 12, Fig. 7, to support the belly flap and straighten up the fish before it is slit. The guides 12 merge into walls 13 and 14 and a further and wider trough - shaped guide on which saddle the fish rides to a second working tool. In Fig. 8 the spike guide 2 is automatically raised (or lowered) in accordance with the size of the fish by a feeler 26 moved by the back of the fish, which lowers (or raises) a stoppin 18 and a headed rod 34 which latter frees a stop 21 from contact with a lug 20 on the spike assembly. A fixed stop 31 prevents the spike from being raised too high. Specification 771,035 is referred to.

Title: Improvements in or relating to electric switches with automatic trip mechanism
IPC: H01H73/56
Filed: 1938-08-23
Abstract: 505,153. Electrically - released switches. PATENTVERWERTUNGS-GES. HERMES. Aug. 23, 1938, No. 24829. Convention date, Aug. 26, 1937. [Class 38 (v)] An automatic switch for consumers' installations is provided with a single-part fireproof insulating base member having the trip mechanism and thermal trip device mounted on the front thereof. A recess in the front surface of the base constitutes a spark-chamber for the contacts, and a recess in the back surface receives an overload current trip magnet and armature. The arrangement enables a reduction in height to be obtained in switches having the parts arranged one above the other so as to reduce the area of the base. The Figures show the invention applied to a switch having its contacts, tripping and resetting mechanism, bimetal element 14, and manual release arranged generally as in Specification 481,407. The base 1 is recessed at 2 to receive the spirally-wound, strip-conductor coil 3 and its spool 4, also an iron core 7 apertured to receive a trip rod 9 on which is adjustably mounted the pot-shaped, spring-controlled armature 6. The core 7 is retained by an iron plate 12 which is secured by a screw 13 in a recess on a boss on either side of which is mounted a fixed contact, the fixed contacts being adapted to be bridged by the movable contact 36. The top of the spark-chamber recess 15 housing the contacts is closed by an iron plate 16, which serves as a stop for the open position of contact 36 and co-operates with plate 12 to produce a blow-out field, the quenching being further aided by providing 16 with an inner lining plate of fibre or other deionizing-gas evolving material impregnated, if desired, with an ammonia compound. A cap 19 of pressed material is secured to the base 1 by a screw 32 and nut 33 pressed into the cap, the screw 32 passing through a tubular rivet 31 by means of which the coil and spool, the plate 16, and side plates 29 housing the mechanism proper, are secured to the base. The manual trip link 24 has lateral projections (not shown) to prevent its falling out of the cap. Four connecting terminals 49 are inserted in a slot 50 formed in the base 1 by the intersection of discs during pressing, and are provided with fixing screws 53 and screws 51, 52 for the external and internal connections, respectively, Fig. 4. This arrangement may be modified to reduce the base area by closing the recess 2 in the back of the base 54, Fig. 12, by an insulating member into which terminals 56 are screwed, the member being secured by a metal stay 57 secured to the base 54 by screws 58 engaging nuts 59 located in slots 60 in the base. Alternative shapes of latching projection to that B of Fig. 1 are shown, providing varying angles between the toggle-pivots, and accordingly varying bearing pressures between B and the latch 51, the minimum pressure, and hence minimum tripping force, being obtained when these pivots are substantially collinear, Fig. 7b (not shown).

Title: Improvements in holders for thermionic valves for use in wireless systems
IPC: H01R33/92
Filed: 1923-10-06
Abstract: 226,895. Mitchell, G. A. Oct. 6, 1923. Vacuum tubes. - An additional valve is connected directly to one of the valves of a set, i.e., plate to plate, grid to grid, and filament to filament, for the purpose of amplifying the signal to be transmitted or received. A valve holder for this purpose consists of a strip or sheet 1 of insulating material on which two or more sets of valve legs are mounted, corresponding, valve legs being connected to one another by wires. One of the sets of valve legs may be replaced by sleeves 9 inserted in the insulating material, so that the pins of a valve inserted therein may extend below the strip and may be then inserted in the holder in the set. Alternatively, the sleeves may be dispensed with, the wires 4 connecting the additional holder being formed into loops which engage the valve pins when they are inserted in the holes in the strip. Reference has been directed by the Comptroller to Specifications 152,811, 153,553, 158,901, 164,105, and 167,584, [all in Class 40 (v), Wireless signalling &c.].

IPC: B01F5/04
Filed: 1959-07-21
Abstract: 862,631. Injectors. DEUTSCH, C. J., DEUTSCH, B., and DEUTSCH, H., [trading as STANDARD MACHINE & MANUFACTURING CO.]. July 21, 1959, No. 24987/59. Class 71. A fluid mixing device for attachment to a tap comprises a skirt member 16, having a partition 20 with an orifice 24, which is secured to a member 25 to form a chamber 30 which is open to the atmosphere. The member 25 has a Venturi shaped passageway 34 axially aligned with the orifice 24 and having a restricted portion 37. A secondary liquid passageway 47, controlled by an adjustable throttle valve 51, communicates with the passageway 34 below the restriction 37 while a groove 41 surrounding the restriction communicates with the atmosphere through a passage controlled by a valve 43 which closes on a seat 44 and is biassed to the open position by a spring 45. In operation when a stream of primary liquid flows through the device the valve 43 being open prevents secondary liquid being drawn in. On pressing the valve to its closed position the reduced pressure in the groove 41 holds the valve closed and secondary liquid is drawn in and mixes with the primary liquid. If uncontaminated liquid is again required the supply is turned off when the valve 43 will be forced open by the spring and the tap may then be turned on again. The provision of the chamber 30 in permanent communication with the atmosphere prevents back flow of the secondary liquid in the event of a sudden interruption or reduced pressure in the primary supply.

IPC: H03C1/10
Filed: 1922-09-15
Abstract: 186,070. British Thomson - Houston Co., Ltd., (Assignees of Alexanderson, E. F. W.). Sept. 17, 1921, [Convention date]. Modulating systems.-Signalling is effected in a vacuum-tube oscillation-producing system by regulating the degree of coupling between the oscillation circuit and the aerial in accordance with microphone or other signalling variations. In this way, the back electromotive force induced across the coupling in the oscillation circuit is liept substantially constant and approximates to the potential of the direct-current supply, so that power losses in the tube circuit are reduced. The thermionic tube 1 is retroactively coupled through the coils 5, 9 and supplies power to the aerial through the looselyccupled coils 8, 13. The secondary 13 is shunted by a magnetic amplifier of the type described in Specification 7151/13. Signal currents from a microphone 20 are transferred to the saturation winding 16 of the magnetic amplifier, and thereby vary the effective impedance of the highfrequency windings 14, 15 from a substantially high to a substantially low value, giving rise, in turn, to corresponding fluctuations in the power supplied across the transformers 8, 13 to the radiating circuit 11, 9. The shunt circuit cornprising the magnetic amplifier diverts more or less energy from the aerial according as its effective impedance is diminished or increased.
