Abstract: 580,170. Linkwork. NASH & THOMPSON, Ltd., NASH, A. G., FRAZER-, WHITAKER, A., and BARNES, N. Jan. 5, 1942, No. 158. [Class 80 (iii)] [Also in Group XL] A mechanism for moving a reflector to project a beam in a substantially spiral path, in which the reflector is adapted to oscillate about an axis in a frame which is rotatable about another axis intersecting the axis of oscillation, is characterized in that the oscillatory motion is given to the reflector by a member rotating relatively to the frame on the same axis and carrying a rotatable annulus the axis of which is offset from the axis of revolution and passes through the point of intersection of the axes of oscillation and rotation, this annulus co-operating with a fork or equivalent member fixed relatively to the reflector. As shown, a reflector 1 is carried by a frame 3 provided with trunnions 4 pivoted in a frame 6 secured to a tubular shaft 7. An inner hollow shaft 17 carries an inclined eccentric 16 the axis of which passes through the point of intersection of the axis of rotation of the shaft 7 and the axis of the trunnions 4, about which latter axis the reflector is oscillated. The eccentric 16 carries on ball bearings an annulus 15 which is engaged between bearing-pieces 14 secured to portions 13 of the frame 3 forming a fork. The shafts 7, 17 are driven at different speeds, through chain and sprocket gearing from an hydraulic motor (not shown), the consequent rotation of the eccentric 16 in relation to the fork 13 causing gradual tilting of the member 3 and reflectors about the axis of the trunnions 4, so that the beam is projected at a varying angle to its axis of rotation 12.

Title: Automatic weighing machine with rotating multi-compartment weighing vessel
IPC: G01G13/24
Filed: 1928-01-03
Abstract: 284,231. Meyer, O. Jan. 25, 1927, [Convention date]. Automatic-feed weighers. - In an automatic weighing-apparatus having g a rotatablymounted multi-compartment weighing vessel, two levers are mounted on the shaft of a closure member controlling the supply of material to the weighing vessel, the first lever being rigidly connected to the closure member and both levers being adapted simultaneously to engage a stop on the weighing vessel corresponding to the operative compartment, and the second lever being so constructed and arranged that, after the first lever and closure member have been released from the stop, the second lever is still engaged by the stop and arrests the closure member before the supply of material is completely out off, the second lever being released by the stop upon the completion of the weighing operation. At the commencement of the weighing operation, the stop k corresponding to the upper compartment b of the weighing vessel holds back a lever e, rigidly secured to a shaft o and closure member d, and thus allows a full feed of material from the supply hopper c. Loose on the shaft o and also resting against the stop k is a second lever f the angular movement of which relative to the lever e is limited by a screw s. When the weighing vessel sinks under the increasing load the stop k liberates the lever e allowing the closure member d to fall to the reduced-feed position shown, in which position it is retained by the engagement of the stop with a lever f against which the screw s now abuts. Further sinking of the weighing vessel permits the lever f to escape and the closure member falls and cuts off the feed. The size of the opening for the reduced feed may be altered by adjusting the screw s.

Abstract: 1,070,661. Gain control of transistor amplifiers. STANDARD TELEPHONES & CABLES Ltd. Jan. 4, 1965 [Jan. 4, 1964]. No. 272/65. Heading H3T. In a two transistor amplifier, having a common emitter resistor 6, the gain is controlled by an A.G.C. voltage applied to the base electrode of the second transistor 4 such that the control effected in the first transistor 2 to increase its conduction is substantially complete by the time control to reduce conduction of the second transistor 4 is initiated. An increasing control voltage 11 causes the emitter current of transistor 4 to reduce so that the voltage across resistor 6 decreases and alters the bias voltage across transistor 1 causing it to conduct more and so stabilize the voltage across resistor 6. Additional amplified control voltage from the collector of transistor 4 may be fed back via lead 15 to the base electrode of transistor 1. The coupling elements 3, 5 between the transistors may contain transformers R.C. networks or tuned circuits.

Abstract: 1,036,231. Hydraulic couplings. SCHWITZER CORPORATION. Jan. 3, 1964 [Jan. 7, 1963], No. 307/64. Heading F2C. In an hydraulic coupling for driving an engine cooling fan of the type in which the drive is provided by fluid shear on a coupling disc 26 around the outer portion of which liquid circulates toroidally in a drive chamber 24, as described in Specification 841,703, the flow of liquid between chamber 24 and a reservoir 23 is controlled automatically in accordance with temperature or speed by a pumping member to vary the slip. As shown in Fig. 2, a small cylindrical member 39 is carried at the end of a spring strip 34 which is engaged by an axial plunger 67 connected to a bimetallic element 64 subjected to ambient air temperature. The member 39 passes through an opening in the disc 19 separating chambers 23, 24 and is so arranged that at high temperature it does not protrude into the drive chamber 24, but as the temperature falls the element 64 operates to move it into chamber 24 to pump liquid into reservoir 23 through a port in disc 19 to increase slip. In a modified arrangement, Fig. 9 (not shown), the element 64 and plunger 67 are omitted, the member 34 carrying control member 39 forming the bimetallic element, so that slip is dependent upon the temperature of the liquid in the coupling. In a further embodiment, Fig. 5 (not shown), the bimetallic element is carried by the disc 19 and arranged to be deflected into the drive chamber 24 to control the volume of liquid in the chamber. Fig. 10 shows an arrangement additionally responsive to rotary speed, the bimetallic element 93 carrying the member 39 being secured to the separating disc 91 and bowed outwardly as shown, and carrying a centrifugal weight 97. In a modification of this embodiment. Fig. 12 (not shown), the element 39 and weight 97 are carried by a plain metal strip actuated by a temperature-responsive plunger 67 as in Fig. 1.

Abstract: 656,372. Fishing. ANDRIST, D. M. Jan. 10, 1949, No. 635. Convention date, Jan. 30, 1948. [Class 48] A device, of the kind described in Specification 634,965, for baiting a fishing line having a plurality of hooks secured thereto at spaced intervals, comprises hookguiding means in combination with linedirecting means and bait-severing means, and means for affixing a piece of bait to a hook. A line 47 carrying hooks 49 passes through a tube 25, the inlet of which is formed in the manner described in Specification 634,965 and is adapted to guide the hooks into the tube so that their barbs project upwardly through a slot formed in the top of the tube. The bait in the form of a fish is placed in a funnel 6 fixed to a frame which is pivotally mounted on the base of the apparatus, said frame also carrying a knife 8. Each hook in passing along the slot encounters a pin 9 projecting from the frame and thereby swings the latter, when the knife 8 co-operates with a fixed knife 10 to sever a piece 7a of the bait projecting from the funnel. Further movement of the hook carries the pin clear of the slot when a spring returns the frame to its original position. The hook carries the piece 7a into contact with a spring-biassed swinging flap 30, so ensuring that the hook is embedded in the piece of bait. In a modification the tube consists of two members hinged together longitudinally.
