Title: Improvements relating to lockers or receptacles particularly for drying clothes
IPC: D06F58/10
Filed: 1944-02-07
Abstract: 571,416. Drying clothes. HARRIS & SHELDON, Ltd.. SANKEY & SONS, Ltd.. J.. and BUTLER, H. G. Feb. 7, 1944, No. 2187. [Class 34 (i)] A locker 1 for drying clothes is provided with one or a plurality of apertures 2a through which hot drying air may pass from a supply duct 2 up into the interior of the locker and which are normally closed by a flap or shutter 3, the latter being actuated to open the apertures by the weight of the clothes when hung upon a hook or hooks 5, Fig. 2, or placed upon a perforated bottom or shelf, 25, Fig. 8, located within said locker. In the construction shown in Fig. 2, the flap 3 is maintained in its closed position by a torsion spring 4 and is opened by downward movement of the hooks 5 and supporting bar 6 through levers 7, 9, 8, a long vertical rod 11 and toggle mechanism 12. Movement of the hooks 5 may, however, be communicated to the flap 3 by flexible cables, &c. In Fig. 8 the flap is opened by the direct pressure of one edge of the shelf 25, the shelf being mounted on springs 28 as shown or, alternatively, hinged to the locker along the parallel edge remote from the flap. Fig. 10 shows a modification in which the spring- pressed flap 3 is actuated by a pair of vertical side rods 29, hooks 5 being suspended between the tops of these rods and a perforated shelf 25 secured to near the lower ends thereof. The lockers may be in two superposed rows, with those in each row arranged in pairs back to back, with a common hot air supply duct 2.

Title: Replicating Microphotographic Apparatus
IPC: G03F7/20
Filed: 1968-01-15
Abstract: 1,197,361. Photo-copying apparatus. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. Jan. 15, 1968 [Jan. 25, 1967], No. 2231/68. Heading G2A. In a step and repeat photographic reducing apparatus, an object pattern 3 is inserted into a frame 32 on a first carrier 2 for copying on to a photo-sensitive surface 15 held by a second carrier 9 which is slowly and continuously moved in an X-direction relative to a baseplate 8. A grating 17 on the second carrier 9 is illuminated by a source 22 and an enlarged image (33) Fig. 7, (not shown) of the grating is focused on the plane of photo-cell 21 by a lens 19. As the carrier 9 moves, the lines (33) travel across the photo-cells 21 which each have fine receiving slits and the outputs of which are applied to a balanced comparison circuit 57 which triggers a flasher 4 when a predetermined relationship is present between the illuminations received by both cells 21. This causes a reduced image of the pattern 3 to be formed on a particular area of the surface 15 by reducing lens 14. As movement of the carrier 9 in the X- direction continues, a line of reduced images of the pattern 3 is formed. When the carrier 9 reaches a prescribed end position along the X-axis, means (not shown) arrest its movement and return it at high speed to its initial position. An increment of motion is now imparted along the Y-axis, a screw 12 being rotated to raise the carrier 9 until outputs from photo-cells 20, which co-operate with a gravity 16 in the same way as photo-cell 21 do with the grating 17, via a comparison circuit 61 cause actuators (26) Figs. 3, 4 (not shown) to block Y- movement of the carrier 9. The X-movement is then re-commenced. If desired, the Y-axis movement does not take place, thereby giving only a linear array of images. The single lens 14 may be replaced by a rigid cluster of, e.g. four, lenses for simultaneously forming four pictures on surface 15.

Title: Method for drying peat fuels and the like
IPC: C10F5/00
Filed: 1930-01-22
Abstract: 340,156. Drying peat and similar fuels. BERLIN, D. W., 1A, Tottvõgen, Rasunda, Sweden. Jan, 22, 1930, No. 2276. Convention date, Feb. 6, 1929. [Class 34 (ii).] Peat, sawdust, waste wood, or dry grasses, which may be wet carbonized, are dried by y firstly throwing out the solid fuel from the water constituent, and secondly throwing liquid away from the solid substance. This method is carried out in centrifugal apparatus in which the material is first treated in apparatus with impenetrable walls, and then in apparatus with walls penetrable to liquid. The material thus dried, is subjected to heat treatment for final drying. The first centrifugal separator 1 has an impenetrable wall 2, and the second separator 3 a perforated wall 4. The material is fed from a hopper 5, and a layer of partially dried material settled against the wall 2, this is scraped off into a hopper 9 and fed on to the perforated wall 4, where the rest of the water is removed ; the liquids escape through outlets 8a and 12. The drum 14, shown in Fig. 2, comprises two perforated walls 15, 16, and by displacing one in relation to the other, a penetrable or solid drum may be formed, so that both parts of the process may be carried out in the same drum.

Title: High speed printing system
IPC: B41J1/34
Filed: 1963-01-18
Abstract: 995,571. Printers. CLARY CORPORATION. Jan. 18, 1963 [Feb. 5, 1962], No. 2280/63. Heading B6F. [Also in Division G4] A printer of the type in which a web is brought into contact at selected times with a continuously rotating type-drum is characterized in that a print cycle can commence from the instant that any character on the typedrum passes the printing position. This means that when the printer is being controlled by a data processing device a print cycle commences substantially immediately a " print " signal is received without having to wait until a datum position on the type-drum reaches a reference position. As described a " print " signal on a lead 99, Fig. 7, from a data processing unit 83 passes via a gate 98 to turn on a trigger 105 thereby engaging a one-revolution clutch 53, 73. This causes a unit 87 to produce twelve clock-pulses which are applied via a lead 90, inverter 112, gate 102 and inverter 180 to a series of gates 97 which control print solenoids 30. Each of these gates 97 also receives a signal from an associated comparator 82 when the type-character in the print position agrees with the character it is desired to print, as specified by the data processing unit 83. At the end of the one revolution of the clutch 53, 73 the paper is advanced one line and two extra clock pulses are produced which reset the circuit for a further print cycle. The single revolution clutch can also be energized either by a key 116, or by the data processing unit, in order to advance the paper without any printing taking place. Type-drum.-The type-drum 14, Fig. 2, is freely mounted on bearings 15 on a shaft 17 which is eccentrically rotated in such a way that teeth 22 on the outside of the drum engage with fixed teeth 21, the arrangement being such that for each complete eccentric revolution of the shaft 17 (see also Fig. 1) a different type character is brought down above a row of printing platens 24. When a character is to be printed a solenoid is energized to raise the appropriate platen 24 at the appropriate time. Paper feed.-When a print cycle is begun a one-revolution clutch is engaged. This clutch, in addition to driving a clock-pulse producing unit also drives a cam 63, Fig. 6, which, at the end of a revolution, advances the paper via a pawl 68 and ratchet wheel 72.

Title: Improvements relating to casement or lattice windows
IPC: E06B3/34
Filed: 1931-01-23
Abstract: 371,060. Window fastenings ; stays. LAURENCE, I. L., 386, Goldhawk Road, London. Jan. 23, 1931; No. 2359. [Classes 44 and 65 (i).] Relates to casement or lattice windows of the kind which are adapted to swing both inwardly and outwardly. According to the invention, the window comprises, in combination, (1) a thin slidable plate or strip 4, Figs. 1 and 2, carried by the sash frame 1, or the outer fixed frame 2, and (2) a pivoted draught-excluding flap 3, Fig. 3, mounted along the lower edge of the sash frame. In the form shown, the plate 4 is mounted within the frame 2 and is provided with pins 4a which extend through horizontal slots 2e in plates 5 secured to the frame 2. The pins carry knobs 4b which enable the plate 4 to be moved by hand. In the position shown, the plate prevents the inward movement of the hinged sash, and also co-operates with a pivoted catch 6 to effect the locking of the casement in the closed position. A perforated pivoted stay 7 co-operates with a pin 8 to retain the sash in its required open position. This pin is hinged to the sill 2f so 'that it may move out of the path of the casement when the latter is swung inwards. In the alternative construction, the plate 4 is carried by the sash frame 1 and near the outer face thereof. Pins on the plate extend inwards through the sash frame in order that the plate may be operated from the inside.

Title: Improvements in or relating to apparatus for cleaning and preparing tins for use in cooking
IPC: A47L15/24
Filed: 1928-01-25
Abstract: 312,377. Lyons & Co., Ltd., J., and Herbert, S. G. Jan. 25, 1928. Baking-trays and the like, cleaning. - Baking-tins are carried on a zigzag conveyer 2 through washing, drying and cooling chambers. Fig. 1<a> shows the washing or rinsing portion of the apparatus, and Fig. 2 shows the construction of the conveyer chains, projecting attachment links 3 supporting the tins in two closelyadjacent paths at the sides of the chain 2. The tins are placed on the conveyer at the position H and pivoted fingers 50 are operated by any displaced tray to stop the conveyer through the electromagnetic device 51. The conveyer is trained into a tower 5 in which the tins are rinsed by water sprays 10<a>, the tins being prevented from falling from the conveyer by a fixed guide 9 which is looped over the top pulley 7 and may be slightly eccentric thereto to prevent the tins from jamming. The water spray is provided by pumps 12, 13. Brushes 19, 20 adjustable by pivoted quadrants 21. 22 to take up wear assist in the cleaning. The tins are, after rinsing, carried by the conveyer 2 to a drying chamber, the conveyer being arranged to zigzag over top and bottom pulleys through the drying chamber which is provided with vertical baffles to direct the hot drying air, which is supplied from a trunk, through a zigzag path. The conveyer then passes to a cooling chamber through which cool air is circulated. On leaving the cooler, the trays are discharged over a shoot on to a transverse delivery conveyer. According to the Provisional Specification, the guide rails 9 are prevented from always covering the same portion of the tins and consequently hindering the cleaning by making them sinuous, or interrupting them or by arranging them in staggered lengths. The brushes 19, 20 may be rotary brushes. Specification 312,378 is referred to.

Title: A variable effect resilient device
IPC: B60G17/02
Filed: 1949-01-29
Abstract: 658,665. Aircraft controls. BLACKBURN & GENERAL AIRCRAFT, Ltd., and ALLAN, J. Jan. 29, 1949, No. 2508. [Class 4] [Also in Group XXXII] A spring-loaded device in which the effective strength of its spring may be readily varied, comprises a freely-pivoted lever to which movement may be applied, a spring carried at one end of the lever, an adjustable arm connected at its end to the spring, and means for varying the angular setting of the arm about an axis parallel to the pivotal axis of the lever, such that when the point of connection of the arm to the spring coincides with the pivot of the lever, the effective strength of the spring is substantially nil and as these points are moved away from one another the effective strength of the spring is increased up to a maximum when the adjustable arm is displaced through an angle of some 90 degrees. In the arrangement shown in Fig. 1, for varying the artificial feel of poweroperated aircraft controls, a member 4 is moved by the pilot to operate a control surface, and a lever 1 which is movable by means of the member 4 about fixed axis 2, is pivotably connected at its free end to a rod or tube 7 carrying oppositely-acting springs 8, 9 of equal strength, which are effective on a member 10 intermediate its springs and slidable on the rod 7. An arm 11 equal in length to the lever 1 is pivotably connected between the member 10 and another fixed axis 12, parallel to the axis 2. An extension 11<SP>1</SP> of the arm 11 is pivotally connected to a member 15 the movement of which is effective to vary the angular position of the arm 11 to change the effective stiffness of the springs 8, 9. The member 15 may be operated by mechanism accessible to the pilot or by a jack or the like controlled by a pressure-sensitive device automatically in dependence upon changes in speed of flight. Operation of the member 15 to rock the arm 11 from the position in which its pivotal connection to the member 10 moves to either side of the position where this pivotal connection is substantially coincident with the axis 2, results in movement of the lever 1 by the member 4 being resisted by one or the other of the springs 8, 9, the resistance being small or negligible for small displacements of the arm 11 from the position shown and greatest when the latter is displaced through substantially 90 degrees. In order to obtain a balanced construction, the lever 1 and arm 11 are duplicated as shown in Fig. 2. In a modification, movement of the member 4 in one direction only may be resisted by a single spring. In a further modification, Fig. 6 (not shown), a single spring is enclosed in a casing to which the arm 11 is connected and which is movable in either direction relative to the rod 7 to compress the spring against end-plates which are held against movement away from one another by collars fixed to the rod.
