Title: Improvements in or relating to brushes for use in machines for washing or cleaning fish or for other purposes
IPC: A22C25/02
Filed: 1927-01-24
Abstract: 283,744. Musgrave & Co., Ltd., and Eldershaw, F. H. Jan. 24, 1927. Fish, treating.-Brushes for use in machines for washing or cleaning fish and for other purposes have bristles that form a normal brushing- surface and additional bristles that can be introduced into or withdrawn from the brushing surface to vary the stiffness of the latter. As shown, Figs. 2 and 3, the brush comprises a series of longitudinal lags E provided with bristles E<1> and secured to supports F loose on the shaft G, and adjustable lags H with shorter or stiffer bristles H<1> arranged between the lags E so as to be movable radially by means of extensions H<2> fitting in guides or slots in the end and middle support F. Pins H<3> on the extensions engage in radial slots in the supports and project into curved slots I<1>, Fig. 4, in discs 1 fixed to the shaft G. Nuts II<4> on the outer ends of the pins H<3> at the ends of the brush are provided to clamp the discs I to the end supports F. By slackening the nuts H<4> and turning the supports F with the lags E, H on the shaft G, the pins H<3> are moved to the outer ends of the slots I<1> and the bristles H<1> moved outwards. In a modification, Figs. 5 and 6, the radial movement of the lags H is effected by means of toggle levers J. The supports F of the lags E are fixed to the shaft G, and the lags H have extensions H<2> fitting in guides or slots in the supports F at the ends and middle of the brush. The links J are pivoted together at their inner ends, while their outer ends are pivoted at the extensions H<2> and to the brackets F<1> on the supports F. Rods K passing through the supports F connect the links J pertaining to each adjustable lag H and are movable longitudinally as by means of nuts L, M on the shaft G to move the adjustable lags inwards or outwards The link K may be operated independently so that any one or more of the adjustable brushes can be rendered operative as desired. One or more of the brushes may be used in a fish washing or cleaning machine.

Title: Electrical timer
Inventor: KELLEIGH WALDO JAMES
IPC: G04F3/06
Filed: 1951-01-29
Abstract: 679,596. Time switches. GENERAL CONTROL CO. Jan. 29, 1951. No. 2201/51. Class 38 (v). A time switch adapted to operate contacts S1-S5 at the end of a time period is set in operation by closing a switch Ss whereupon a solenoid 86 is connected in circuit between lines t1, t2 ; the solenoid operates a lever 43 pivoted at 82 thereby operating (a) a clutch 35 which connects a shaft 19 driven by a continuously running motor 18 to a timing disc 47 and (b) a switch s2 which completes a maintaining circuit for the solenoid 86 ; the timing disc 47 rotates, winding up a spring 81, and at the end of the time period a projection 49 on it engages a lever carried by an adjustable disc 52, the lever in turn operating a switch s1 also carried by the disc 52 so that the maintaining circuit for the solenoid 86 is broken and a relay 126, controlling the contacts S1 ... S5, operated. In the arrangement shown in Fig. 8, the relay 126 is energized to start with and is de-energgized by the operation of switch s2 at the beginning of the time period. At the end of the time period when switch s1 operates and solenoid 86 is de-energized, the lever 43 moves to declutch the disc 47, which then returns to its starting position under the influence of the spring 81, and to release the switch s2 which now completes the circuit to the relay 126 since the switch s1 has also been released by the return of the disc 47. In a modification, Fig. 9 (not shown), the relay 126 instead of being de-energized and energized respectively at the beginning and end of the time period is normally de-energized and only energized at the end of the time period. The lever 43, in addition to its other functions, carries a roller 103 which acts as a brake to the return movement of the disc 47 and, by entering a slot 106, determines accurately its zero position. Should the supply current fail, the lever 43 is locked in its clutching position by a lever 174 so that when power is restored the time cycle continues. The relay 126 comprises a solenoid which operates a plunger, Fig. 2 (not shown), which operates a lever about a shaft 131 and causes a bar 137 to operate the contact springs 144 of the five switches S1 to S5. An additional switch s3, operable by a push 158 serves to reset the device, if desired, during the timing cycle. A switch Si also enables the switches S1 to S5 to be operated without timing. The adjustment of the disc 52 to determine the length of the time period is effected by rotation of a knob having on its shaft a rubber grommet engaging the edge of the disc 52.

Abstract: 632,625. Transformers and inductances. GENERAL ELECTRIC CO., Ltd., MERCER, E. L., and STAFFORD, L. J. Jan. 26, 1948, No. 2302. [Class 38 (ii)] [Also in Group XL (c)] A turret type coilholder for holding aerial circuit coils comprises two metallic discs 1, 2 spaced apart with the planes containing their peripheries parallel to each other and each disc has a plurality of projections, apertures or like locating means to co-operate with the coil formers 15. At least the disc 2 is of resilient material and is so displaced from the other that its resiliency allows the insertion of the coil formers 15. The disc 1 is of a dish-shape and in the flat rim portion are formed ten pairs of apertures 11 symmetrically spaced. The disc 2 has ten radial slots 7 also symmetrically-spaced; thus ten tongues 8 are formed in each of which a hole 9 and a slot 10 are cut away. The apertures 11 and the circles 9 serve to accommodate the end portions of the coil formers 15. The turret can be rotated by a shaft passing through a central hole 4 to which it is fixed by screws 6. Each coil former has four integral contact members 13 to which the coil windings are directly connected. These members 13 co-operate selectively with a set of fixed contact members in order to select a required frequency band on rotation of the turret. Each coil former 15 has an adjustable magnetic dust core 14 carried by a rod passing through an I-shape brass plate 18. Similar turrets may be used for switching other coils in radio-frequency circuits or in oscillator circuit and they may also be applied to signal generators or wavemeters.

Abstract: 924,594. Nuclear reactors. GENERAL DYNAMICS CORPORATION. Jan. 22, 1962 [Jan. 31, 1961], No. 2311/62. Class 39 (4). A nuclear reactor system comprising a tank containing a fluid coolant, such as ordinary or heavy water, in which is supported a reactive core has a radiation shield movable into and out of the path of fast n- and γ-radiation from the core to a radiation zone outside the core to change the intensity and nature of the radiation in this zone. In the embodiment described, a cylindrical core 11 containing fuel elements 15 supported in a tubular shroud 17 is mounted within a curved projection 19 in the wall of the reactor tank so that fast n- and y-radiation from the core 11 enters an adjacent radiation room. The walls of the room are of concrete which is covered with a wood lining 23 in order to minimise the effects of induced radiation in the concrete. A curved radiation shield 25 is mounted on a platform 109 supported by legs 111 on an hydraulic piston so as to be movable from the position shown to a retracted position in which it lies below the level of the core 11. In its extended position, the shield 25 serves as a filter for core γ-rays and a reflector for core neutrons. The shield 25 comprises two arcuate plates 31, 33 of a material of high atomic number, e.g. lead, secured between a base 29 and a top rim 35. A top peripheral spacer 37, a bottom peripheral spacer 39 and two vertical pheripheral spacers 41 are joined to the plates 31, 33 by suitable means, e.g. a lead burning process. In addition, there are interior spacers 45a, 45b . . . extending between the top and bottom peripheral spacers 37, 39 to provide compartments between the plates 31, 33, a passageway E being formed in each compartment by baffles 47a, 47b . . . extending from the top peripheral spacer 37 to a point somewhat above the bottom peripheral spacer 39. The shield 25 is cooled by circulating a coolant, such as water, through these passageways E which are connected in parallel by a coolant manifold assembly 49 comprising inlet and outlet headers 51, 53 formed of arcuate lengths of tubing, and inlet connectors 81a, 81b, 81c, 81d and outlet connectors 93a, 93b, 93c, 93d connecting the headers 51, 53 with opposite ends of the passageways E. Flexible conduits 105, 107 connect the headers 51, 53 with coolant supply and discharge lines 101, 103.

Title: Improvements in or relating to counting apparatus
Filed: 1928-01-24
Abstract: 284,241. British Tabulating Machine Co., Ltd., (Assignees of Ford, E. A.). Jan. 25, 1927, [Convention date]. Statistical apparatus; counters actuated by independent agency; transfer mechanism. - A record-card-controlled statistical machine is combined with a units counter having driving means independent of the driving means for the statistical machine. This units counter is preferably frictionally-driven, the units wheel being normally held against rotation by escapement mechanism under the control of an electromagnet actuated by the impulse received from the cam brushes. The wheel for each denomination is independently driven by the friction' means and is released by means on the wheel of next lower denomination. The invention is applied to the record-card-controlled statistical sorting machine of Specification 242,654 for counting the number of cards sorted into the various boxes. The motor which, through, shaft 18 and gearing 17, 16, 15, 14, Fig. 5, drives the shaft 12 for the counters, is independent of the motor which drives the remainder of the machine. The numeral wheels are driven from the shaft 12 through friction means. Each counter 11, Fig. 4, comprises four numeral wheels 11<a> - - 11<d> for units to thousands respectively, these wheels being loose on a shaft 12 and driven by friction discs 53 having pins 54 extending into a longitudinal slot 47 in this shaft. Rigid with the numeral wheels are escapement wheels 26 which coact with an escapement 27, 35 in the case of the units wheel, Fig. 6, and escapements 39, 42 in the case of the remaining denominations, Fig. 3. These escapements are on a shaft 28 and that for .the units wheel has an arm which is depressed by the armature 31 of a magnet 30 when the latter is momentarily energized by the reading brushes. A lug 36 on each numeral wheel coacts with a cam surface 38, Fig. 3, on the escapement lever belonging to the wheel of next higher denomination so that this wheel is permitted to move one step under the friction drive. There is a counter 11 tor each sorting- box, a counter for cams entering the reject box,. a counter for all cards sorted (except to the reject box), and if desired a counter for all cards passing (including those going to the reject box). Each numeral wheel has a double set of numerals round its periphery and is therefore provided with two transfer lugs 36, 36'. By means of a reversing switch for the motor driving the shaft 12 the latter is reversed for zeroizing whereupon the lug 36, or 36<1>, coacts with the surface 44 to arrest the wheel at zero. Further figures, not shown, illustrate a motor and a detachable, drive for the shaft 12 quite independent of the usual motor for the remainder of the machine.

Abstract: 802,283. Electromagnets; inductors. COLLINS RADIO CO. Jan. 24. 1956, No. 2365/56. Classes 35 and 38 (2). [Also in Group XXXVI] In a device for producing a narrow band of alternating parallel flux across a cylindrical space, e.g. for testing a magnetic workpiece 53, the flux, which is produced by a core 43 carrying a resonant coil 51, is constrained into a narrow gap 12 between two conducting cylinders 13, 14. Supporting screws 22 passing through the insulating mounting tube 21 make contact to external conducting bands 36, 41 which carry the circulating current induced by stray flux. Any irregularity in the permeability or' conductivity of the test-piece 53 changes the inductance of the circuit and so modifies the resonant frequency of the coil 51. Balanced external current flow is achieved by the modification shown in Fig. 11 in which the conducting tubes which may be rectangular, as shown, are transversely split into sections 216, 217 and 218, 219, serially connected by bands 236, 237 and 241, 242 respectively. In this Figure the movable core 253 is shown tapered and adjusted by knob 273 to provide a variable choke.
