Filed: 1948-09-07
Abstract: 653,417. Floor polishing machines. JOHNSON & SON, Inc., S. C. Sept. 7, 1948, No. 23512. [Class 138(i)] A rotary floor polishing machine comprises a circular and rotatable motor support, a horizontally positioned electric motor around the lower portion of which the support rotates, an annular brush attached to the motor support around the periphery thereof, and driving means connecting the support and output shaft of the motor. A cup-shaped motor support 11 to which is attached an annular brush 10 by means of a plurality of clips 34, is rotatably connected to the motor 13 by a member 15 and a ball-bearing 19. The polisher casing 39 is secured to the motor by screws 40 passing through lugs 41 on the motor. The motor shaft 24 extends through a gear housing 22 detachably secured to the motor and drives a pulley 28 through a right angle worm and wheel gearing. The pulley comprises two cone shaped discs 31 one of which is movable towards or away from the other by a nut 32 so that a driving belt 29 connecting the pulley with the rim 30 of the motor support, may be tensioned. The tensioning means may be eliminated providing the belt is made of material which requires no adjustment to keep it taut. With this arrangement the bottom of the motor is positioned below the top portion of the motor support and brush so that the centre of gravity is lowered sufficiently close to the floor to minimize the gyrating oscillating movement of the machine during operation. Specification 455,132 is referred to.

Title: Improvements in or relating to slicing machines
IPC: B26D1/25
Filed: 1945-09-12
Abstract: 599,039. Slicing potato crisps. TOOLEY, H. V. Sept. 12, 1945, No. 23548. [Class 28 (ii)] Potatoes &c. are sliced to make crisps by two cutters 27, 28, which are reciprocated in the same plane along paths which meet at the cutting position. The potatoes are fed by hand into a hopper 23, having a spring-urged side pusher 32 to assist in holding them firmly during cutting slices off the bottom. Each cutter 27, 28 is mounted on its slide 24, 25, each slide being coupled to one arm of a bellcrank lever 19, so that on oscillation of the bell-crank-shaft lever by crank-pin drive, the knives move in a path at right angles or at another angle to each other. Each cutter cuts off a slice from the bottom of a potato in succession, the slice passing out through a gap 30 in its slide. The potato is prevented from dropping out by the forward part of each slide, such forward part being mitred so that as one slide withdraws, the mitre of the other follows it up closely, whereby the bottom of the hopper is always covered and closed. The mitre line produced would intersect the pivot 20 of the bell-crank. The cutters may be corrugated and the corrugations may be deep enough so that the corrugations formed in the slice by one cutter may be cut into by the corrugations of the other cutter so that holes 37, Fig. 4, are formed in the slice, making it into a grille formation.

Title: Concrete pipes
IPC: B28B21/46
Filed: 1972-05-19
Abstract: 1389738 Coiling helices on rotating mandrel STELMO Ltd P R LUCKETT J S MOBBS and A J HARRIS 7 May 1973 [19 May 1972] 23600/72 Heading B3E [Also in Divisions F2 and B5] In a method of making reinforced concrete pipes, a layer of green concrete is deposited on a mandrel and receives helical windings of a flexible binding member and a flexible reinforcing member under tension before the concrete sets. Apparatus for making the pipes includes a mounting 10, 25 for a rotatable mandrel 27 surrounded by a hopper 29 which is movable along the mandrel axis, means 31, 32 for supplying a flexible binding member for winding about concrete deposited through the hopper on to the mandrel and means 38, 40, 48 for supplying a flexible reinforcing member 35 under tension for winding about the concrete before it sets. As shown, a motor 43 drives a set of winding pulleys 40 and the mandrel 27 through sprockets 46, 41, 42, 26 so that the peripheral speed of the pulleys 40 is less than that of the mandrel 27. The reinforcing member 35 is a high tension steel wire which is passed around pulleys 49, 51, 52 on a hydraulic ram 48 mounted on a platform 13. Two sets of such winding arrangement may be provided. The platform 13, which also mounts the hopper 29 and vibrators 30 can be raised or lowered along the mandrel on four chains 15 anchored to an hydraulic ram 19. The binding member, which may be polypropylene string or a woven, textile or metallic tape, is taken from a bobbin 31 and through a tensioner 32. The platform 13 is initially at its lowermost position and the binding and reinforcing members are attached to an end plate (60) (Fig. 3, not shown) of the mandrel which also mounts longitudinal wire reinforcements. Concrete is poured into the hopper 29 which is vibrated and the platform 13 is raised. A further layer of concrete may be deposited on the wound layers. A metal spigot (70), (Fig. 2, not shown), may be bound in the concrete at one end of the mandrel for connecting successive pipe lengths together.

Title: Improvements in or relating to automatic synchronisation of time base circuit arrangements
Inventor: MOTHERSOLE PETER LEONARD
IPC: H03L7/12
Filed: 1954-08-16
Abstract: 789,315. Automatic frequency and phase control systems. MULLARD RADIO VALVE CO., Ltd. Nov. 15, 1955 [Aug. 16, 1954], No. 23774/54. Class 38 (4). A television receiver line time base generator 1 is retroactively stabilized in frequency and phase relative to synchronizing pulses by the amplified output of a phase discriminator 4 and the frequency of the generator is swept periodically over a range when not synchronized with the pulses to enlarge the catching range. The range may be so large that the frequency can lock on to different line frequencies of different transmission systems. As shown, the output of a coincidence gate 3 to which the generated signal and synchronizing pulses are applied controls the on or off condition of a strobe generator 2 causing a low-frequency search sweep of the generator 1. Alternatively the gate 3 and strobe 2 may be dispensed with and the output of the discriminator control a D.C. amplifier 5 back-coupled to act also as an oscillator, at low control voltages, for frequency sweeping the generator 1. Thus the back-coupled D.C. amplifier or strobe 2 may act also as a phase shift or Miller transitron oscillator. The generator 1 may be frequency varied through a resistance valve circuit or may be a grid-controlled multi-vibrator. The input to the phase discriminator 4 from the time base generator may be a harmonic of the frequency of the latter.

Title: Improvements relating to apparatus for conveying powdered or granular materials
IPC: B65G53/22
Filed: 1949-09-15
Abstract: 675,113. Pneumatic conveyers. EVERY, C. E. (Smidth & Co. Aktieselskab, F. L.). July 3, 1950. [Sept. 15, 1949] No. 23851/1949. Class 78 (i) Powdered or granular material is conveyed pneumatically by first fluidising a batch of it in a container solely by the injection of a gas without any substantial rise of pressure and then subjecting it in the same or another container to a substantial pressure by which it is driven in the fluidised state into and along a pipe line. Material is admitted into a container 18, Fig. 1, through an inlet 23 and rests on a conical porous plate 19 of canvas, felt or filter stone. This plate may be replaced by a system of pipes having a large number of openings covered by porous material. Air is supplied to the space 22 below the plate by a pipe 10 and passes through the plate and material to escape through the inlet 23. The supply of material is cut off when the container is full by the actuation of a switch 27 by pressure of the material on the member 24. When the material is fluidised, the valve 3 is opened and it then flows rapidly into the container 1. When the transfer is complete the valve 3 is closed by pressure of the material on a member similar to the member 24 and the valve 11 is opened to admit air to the container through the pipes 12, 13, 14 to force the material through the outlet 8 into the pipe line. Air admitted through the pipe 12 passes through porous screens 15. In a modification the container 18 is a shallow box with an inclined porous bottom and is mounted with its base on the same level as that of a grinding machine supplying material. The top of the tank 41, Fig. 3 is fitted with an inlet 46 and an air outlet 47 incorporating a filter and valve. Aerating devices 42 disposed in the bottom of the tank each consist of a shallow box 45, Fig. 5, having a porous cover 42a. When material is to be discharged, the valve 47 is opened and compressed air is forced by a compressor 44 driven bv the engine of the vehicle through a pipe 43 to the boxes 45. When the material is fluidised, the valve 47 is closed and the pressure rises until the loaded valve 48 is forced open and the material is driven through the outlet 49 to the delivery hose. Material passes from a hopper 73, Fig. 8, through a shoot 68 into a tank 63 and rests on a porous plate 64 through which compressed air passes upwardly from the pipe 70. When the material is fluidised, the piston 66 is forced downwards, thereby closing the shoot 68 and opening a loaded valve 72 leading to the pipe line 71. In modifications (not shown) the transference of material between a silo on shore and a ship's hold is described.

Filed: 1960-07-08
Abstract: 877,704. Rumbling. OETIKER, H. July 8, 1960 [July 9, 1959], No. 23913/60. Class 60. Secondary treatment of formed parts is effected by placing a number of the parts in a container together with grinding or polishing elements and a liquid treatment medium containing borax, and rotating the container. The parts may have been produced by stamping, pressing or drawing and the secondary treatment may be for the purpose of completing their form or shape by grinding, trimming or bevelling, for preparing their surface for subsequent galvanizing or varnishing by cleaning, removing rot and smoothing, or for polishing. For grinding, an aqueous solution containing from 0À5 to 20 gm. of borax per litre is used ; wetting and cleansing media may be added. When the parts treated are of iron, it may be necessary to add a passivator, e.g. sodium nitrate. For polishing, a viscosityincreasing agent, e.g. carboxmethylcellulose is added to the solution. A slippiness-increasing material, e.g. lime, albumin or gum-arabic, may be added to the solution.

Title: Process for sulphurising fatty oil
Filed: 1935-03-21
Abstract: Rubber substitute is obtained by treating animal or vegetable oil with hydrogen polysulphides, preferably at higher temperatures than 100 DEG  C. and in presence of stabilizing substances.  Solid or liquid loading material or mineral oils may also be present.  The product may be further treated by the same process, or by known vulcanizing processes, e.g. with sulphur chloride, or as described in Specification 453,921 with sulphur and sulphuretted hydrogen. Stabilizing agents preferred are such as raise the surface tension; their b.p. may be below the sulphurization temperature; agents specified are tetrachlorethane, dichlorethane, dichlorethylene and methylene bromide.  For example, 25 kg. of a 9--1 mixture of raw hydrogen polysulphides with tetrachlorethane is stirred into 100 kg. of rapeseed oil at 150 DEG  C.; on cooling, sulphur crystallizes out and is filtered off; the thick yellow oil is further treated at 145 DEG  C., with 10--15 kg. of sulphurizing mixture, and is allowed to cool slowly yielding a transparent solid.  Instead of filtering off the sulphur the heating may be continued, in presence or not of hydrogen sulphide and a vulcanizing catalyst, to combine the sulphur and so complete the vulcanization.
