Title: Improvements relating to tuning arrangements for radio and like receivers
Inventor: GAUSS HUBERT EDWARD
IPC: H03J3/10
Filed: 1948-10-27
Abstract: 653,941. Adjusting radio apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 27, 1948, No. 27874. [Class 40 (v)] In a bandspread tuning arrangement for radio receivers or the like comprising a variable reactance for coarse tuning and a variable reactance for fine tuning, a control member being adapted to be selectively coupled to the reactances for effecting their adjustment, means are provided whereby when the coarse tuning has been adjusted by the operator to a position approximately corresponding to the centre of the frequency band over which fine tuning is to be effected, and the control member is coupled to the fine tuning reactance, the coarse tuning reactance is accurately adjusted to the centre of the band and locked in that position during- fine tuning. As shown. in Figs. 1 and 2 a rotatable control shaft 2 carries a cylinder 3 having bevelled edges faced with friction material, and is capable of axial movement so that in one position the cylinder 3 engages with bevelled wheel 5 on the rotatable shaft 4 driving the auxiliary tuning condenser, and in the other position operates the main tuning condenser which is coupled to a tuning drum 8, Fig. 3, through the bevelled wheel 7 and rotatable shaft 6. The drum 8 carries around its circumference a number of adjustable locking- elements 10 provided with V-shaped recesses which co-operate with a resilient finger 22 and position the main tuning condenser in the centre of each band to be spread, the lever 19 carrying the finger being pivoted at 17 together with a pulley-wheel 18 having a pin 20 engaging with a slot in the lever. Around the pulley 18 is a cord attached to a spring 23 secured to the pillar 16 and the other end of the cord is attached to one arm 26 of a bell-crank lever, Fig. 2, the arm 29 of the lever engaging a slot in the shaft 2, so that movement of the shaft to couple it with the main tuning condenser raises the finger 22 clear of the elements 10. The main tuning condenser is adjusted approximately by observing the drum 8 which is marked in frequencies or wavelengths, movement of the shaft 2 to couple it with the finetuning condenser engaging the finger 22 with an element 10, and this moving the drum 10 through a small angle until they are accurately engaged and the drum locked in position. In an alternative arrangement, Figs. 6 and 7 (not shown), a spring-loaded sliding member replaces the pivoted resilient member 22. A click mechanism may be provided for retaining the shaft 2 in its axial position of adjustment, and the shaft 2 may be arranged to be coupled with the auxiliary condenser only if the drum 8 is correctly positioned. The wave-change switch may be arranged so that the auxiliary condenser can be adjusted only when the switch is in a position corresponding to the short-wave range, and to avoid pulling the control outwards a push-button may couple the shaft 2 to one condenser after the shaft has been pushed in to operate the other condenser.

Title: Improvements in methods of and means for stacking articles into layers
IPC: B65B35/52
Filed: 1946-09-19
Abstract: 616,902. Stacking articles. LEVER BROS. & UNILEVER, Ltd., DALZIEL, W., and GRAY, J. W. Sept. 19, 1946, No. 28094. [Class 94 (i)] In a method of stacking articles into layers by forming rows of articles and stacking the rows when formed into layers, a row 4 of said articles is assembled on a portion 2a of a slotted platform 2 and a slotted carrier 3 comprising a floor portion 3a and a tread portion 3b is moved through said platform to raise rows 5 of articles already stacked on another portion 2b thereof and the assembled row is inserted beneath said raised rows. Before the row is complete a trip 25 is free, and levers 24 and 23, and radius plate 18 are positioned as shown in dotted lines in Fig. 6. When a row is complete the trip 25 is prevented from moving and the levers 24 and 23, arm 22, radius plate 18 carrying arm 19 attached to the cam follower 20 riding over cam 21, are as shown in full lines. Rotation of cam 16 lifts cam follower 15 and the arm 14 pivots about roller 17, the slide 13 being moved vertically upwards to lift the carrier 3 into the position shown in Fig. 3. Rotation of cam 6 now moves the carrier 10 to the left to bring the carrier 3 into the position of Figure 4. Cam 16 then allows the arm 14 and the carrier 3 to drop to the position of Fig. 5. Finally cam 6 brings the carrier to the position of Figs. 2 and 6. When the row is incomplete, the roller 17 passes up one side of the plate 18 and the arm 14 pivots about its end connected to member 13 which acquires no vertical motion. The layer 5 is stacked in front of a container 37 and when completed a plate 28 is raised and, through levers 29 and 30, lowers an arm 31 to connect with the end of a lever 32. which, oscillated by cam 33, moves a plate 34 against a spring 35 to push the top of the layer into the container 37 over which is a carton 36 for loading. When the container is full, entry of further layers pushes the carton off to fall on a roller conveyer 38. Worked-out details of a machine emodying the above mechanism are given. According to the Provisional Specification the trip is replaced by a stop-pad at the end of a lever having a forked end and oscillated through two links and a bell-crank lever which supplies vertical motion to the carrier. Also, the floor portion 3a of the carrier 3 may be replaced by a separate mechanism which may be similar to the plate 34.

Title: Improvements in and relating to heating systems employing liquids under pressure
IPC: F24D3/04
Filed: 1933-10-16
Abstract: 426,807. Heating by circulation of fluids. FARRER, J. O., 27, Chancery Lane, and KOCH, E. A. J., 64, Victoria Street, both in London. Oct. 16, 1933, No. 28692. [Class 64 (ii)] In a high-pressure hot-water heating system in which the high-pressure water from a generator 1 is passed through a pressure reducing valve 22 into the supply pipe 23 of a secondary system employing a heat consumer 20 requiring hot water at a pressure lower than that of the main circuit, the formation of vapour due to the reduced pressure is prevented by delivering the colder return liquid from the consumer 20 by a pump 25 to the higher pressure hot liquid before the latter enters the reducing valve. Excess cold liquid leaving the consumer 20 is delivered by the pump to the return pipe 6 of the main system through a valve 31 which is acted upon by the pressure of the flow pipe 4 of the main system so that the pressure tends to close the valve and vice versa by the delivery pressure of the pump 26, so that no flow to the return main can occur until the pump pressure has built up to that of the flow main. The temperature of the water flowing to the reducing valve may be regulated by valves 28, 29, which may also be thermostatically controlled in accordance with the temperature at the reducing valve.

Abstract: 791,516. Filters. WHITE FILTER SALES CO. Sept. 20, 1954, No. 28622/56. Divided out of 791,515. Class 46. A method of filtering liquids comprises adding a loose fibrous material, such as finely-shredded paper, to the entire volume of liquid to be filtered, stirring to produce a uniform dilute slurry, filtering through a fine-mesh filter element and periodically removing the accumulated layer of fibrous filter material, together with the dirt trapped therein, from the surface of the element while both aides of it are substantially wholly immersed in the liquid by agitation of the liquid in the neighbourhood of the filter layer (e.g., by reciprocation of a reticulated member supported outside the fibrous layer), so that the fibrous layer is displaced from the filter element by local liquid turbulence. Each filter element 21 may comprise a bottom 25, having threaded engagement with one of a series of nipples 20, Fig. 3, on a manifold comprising a box 15 from the sides of which extend semi-circular tubes 16, 17 and elbows 18, a stiff perforated cylinder 27 around which is wrapped a sheet 30 of fine-mesh wire gauze, and a cylinder 31 of expanded metal loosely surrounding the gauze cylinder 30 and resting on lugs 32 extending outwardly from the periphery of the bottom 25. The cylinder 31 may be raised and lowered, to agitate a layer of paper fibres located between itself and the cylinder 30 and also to agitate the liquid in the vicinity of the layer, by a handle 33 when the top of the filter casing (not shown) is removed. Liquid, e.g., dirty dry-cleaning solvent, is run into a tank 10, Fig. 1, and a few sheets of waste paper are passed through a shredder 11. The mixture is stirred and pumped to a chamber 12 housing the manifold and filter elements, filtrate passing through a valve 37 into a storage reservoir 13. When the layer of fibres has to be removed from each filter element the level of liquid is lowered until the filter elements are just covered, whereupon the cover is removed and the handles 33 operated as above. Fibres may be removed from the bottom of the chamber 12 by opening a discharge valve 36 and a pet cock 19, the slurry being received in a felt bag or filter basket 38 and filtrate pumped therefrom at 40. Figs. 5 and 6 show the mechanism for feeding the paper to the shredder 11. The mechanism comprises a flattened horn 46, Fig. 5, leading to the space between a knurled driven roller 45, Fig. 6, and a spring-loaded idler roller 44 which may also be knurled. A second flattened horn 47 leads therefrom to the shredder.
