Abstract: 1,103,055. Travelling band filter. SVENSKA FLAKTFABRIKEN A.B. 30, Jan., 1967 [8, Feb., 1966], No. 4499/67. Heading B1T. In a travelling band filter, filter web 1 is entrained over staggered rolls 3, 4 and wound from a supply roll 2 to a take-up roll 6, rolls 4, 6 being driven at constant speeds, such that the peripheral speed of rolls 4 exceeds or equals the maximum peripheral speed of web on roll 6 when roll 6 is full. The rolls are driven by a motor 8, through gears arranged on a common shaft 7 and chains, rolls 4 being linked by two eccentric rods 5 displaced 90 degrees apart at opposite ends. Shaft 7 supports a free roll 9, and rolls 3 are free. The web is moved by rolls 4 until it becomes slack and thereby relieves the frictional contact with the rolls, after which its movement ceases until roll 6 takes up the slack and restores the driving contact.

Title: Improvements relating to adjustable seats
Inventor: KORNER REGINALD JOHN
IPC: A47C3/38
Filed: 1959-02-10
Abstract: 875,481. Seats. MORRIS MOTORS Ltd. Feb. 1, 1960 [Feb. 10, 1959], No. 4562/59. Class 52(2). In an adjustable seat supported on crossed stays 2, 3 which are pivoted at 4, 5 and 6 and slidably pivoted in slot 2, 8 clamping means operating through over-lapping slots 8 determine the point at which the stays intersect and, accordingly, the angle of adjustment of the seat. The clamping means may include a screw-threaded rod passing under the seat and carrying a knurled clamping disc which presses a serrated clamping block 12 and the serrated flanges of stay 3 together. As long as the block 12 cannot be moved along the stay, the seat cannot be angularly adjusted. Accordingly, a spring washer is provided to disengage the serrations when the clamping means is loosened to allow the angular adjustment. For adjusting the height of the seat, the serrations remain engaged and a double start screw-thread 25 runs in a nut carried by draw bars 27 as handle 21 is turned to move the pivot along slot 28. Runners 7 are carried on slides and located by means of levers 30 engaging notches in the slides (Fig. 3, not shown).

Abstract: 1533481 Moulds for cementitious material ASAHI GLASS CO Ltd 6 Feb 1976 [18 Feb 1975 (2)] 04735/76 Heading B5A Wet cementitious material 47 (Fig. 11) is charged into a lower mould 45, a filler material 49 (Fig. 12) surrounded by a first mould frame 48 is charged directly on to the cementitious material, a film impervious to and (or more impervious than the filler) is placed over the filler, and the filler is fixed by suction to form an upper hardening mould. Preferably the lower mould 45 is removed after partial hardening, and the cementitious material left to harden on the upper mould. The lower mould 45 is produced by casting filler material 5 (Fig. 2) over a film-covered wood, metal or gypsum master model 1. The filler is covered with a second film and stiffened by evacuation through filters 3A/B on the surrounding frame 4. The master model 1 is removed by compressed air passed through its pores, or is destroyed by heating or dissolving, and the mould inverted for casting in the Fig. 11 position. After heat setting, the concrete protected by the film 2 (Fig. 2) is removed from its moulds by release of the fillers into a hopper (see Fig. 15, not reproduced). The fillers may embed heating elements, or tubular filters used to suck away excess water. The films comprise vacuum formed thermoplastic sheets, sprayed plastisol, metal, rubber, asbestos, paper, glass cloth, powder or powder- and-binder. The fillers comprise sand, hollowparticles of metal, powdered metal or wood, glass or plastics, wood fibres, vermiculite or lightweight aggregate. Magnetic particles can be added for magnetic as well as suction stiffening. The cementitious material comprises Portland-, slag-, alumina, Roman-, lime- or magnesia cement or gypsum mixed with sand, stone and chopped glass, asbestos, carbon or synthetic fibres. Glass wool, steel wool, resin and blowing agent are included, and decoration effected by colouring, cloth, paper, stone powder, sand or wood powder.

An emergency stop gear for a tractor with mechanism driven from a power take-off comprises a switch associated with the mechanism which, when closed, energizes a solenoid 5 to hold a manually-operable plunger 6 depressed, whereby a fuel cut-off valve operated by cable 15 is held open and can be closed to stop the engine by opening the switch. The plunger 6 is connected to a cap 7 having a bayonet slot connection 9, 10 with a casing 3 enabling the plunger to be depressed and turned angular to lock it in operative position when the take-off is not in use. The switch in the mechanism driven from the power take-off is connected to a plug 21 engaging a socket 20 which is connected by disconnectible leads 18, 19 to solenoid 5. When plug 21 is engaged, angular turning of the cap 7 is prevented and the plunger 6 can then only be held depressed by the solenoid 5, the circuit of which is closed by a contact 17 on the plunger engaging contact 16.

An arm 19 on the shaft 9 is at the same time rotated and moves the tube 5 by means of the adjustable link 20 which is attached to a spring collar 21 on the tube. In another form, the armatures of a pair of solenoids arranged on opposite sides of the tubular member which carries the lamp bulb are connected by lateral extensions to the tubular member so as to move it forwards or backwards. A rack on the tubular member meshes with a pinion wheel on the spindle about which the screen rotates. A pair of coaxial pins may replace the spindle. The reflector may be in two parts hinged together and normally closed. The part carrying the bulb is moved by energizing a solenoid, so as to form a gap through which the shield is swung by means of another solenoid.
