Abstract: 1418032 Display devices ELLIOTT BROS (LONDON) Ltd 16 Feb 1973 [20 April 1972] 18369/72 Heading G5C [Also in Division H1] A visual position indictor, which may be an illuminated switch, has a transparent displaceable body 1 which may receive light from lamp 11 through differently coloured regions 6 or 7 depending on the axial position of the body in direction 13, this light being reflected forward by inclined face 4 to illuminate an opalescent display face 3. Another embodiment, Fig. 4, provides reflecting faces 33, 34 as truncated cones to permit rotation of body 31, as for a rotary switch, whilst changing the colour of display 32 only on axial displacement of body 31. A further form responds to rotation of the body portion by dividing the conical portion axially into two differently coloured halves of semi-circular section.

Filed: 1917-12-15
Abstract: 121,511. Petter, E. W., and Brooks, H. Dec. 15, 1917. Regulating. - In order to ensure ignition during light loads, fuel is injected at some interval of time in advance of the usual period either alone or followed by an injection at the ordinary time. Fig. 1 shows mechanism for injecting both charges by a single pump a which is normally worked by a bowl p. The advance injection is effected through the levers f and k, the latter being mounted on an eccentric j by which it is brought into the path of the lever o on its back stroke. In multicylinder engines the pumps of each cylinder may be made to deliver into another cylinder which fires later by providing three-way cocks 8, 9, Fig. 4, and cross-connexions in the pump delivery pipes 6, 7. Two pumps may be used, one of which is worked on the forward and the other on the backward stroke of a lever.

Abstract: 204,157. Ford, A. July 7, 1922. Card games.-A calculating game is played with a set of cards or the like bearing numerals, words, &c. and/or pictorial representations of well-known or other objects in varying order, and one or more devices representing symbols used in arithmetic. The cards may be printed in colours and the symbols may be either printed on cards, as shown in Fig. 3, or cut from material to the requisite shape, as shown in Fig. 4, the words " Multiply," " Divide," &c. preferably being included in the design. As shown in Fig. 2, a card showing four stools has printed on it the numerals " 4 " and the words " Four." In playing the game, one of the symbols is chosen and placed before each player. The dealer having dealt the cards takes two of his cards and planes them face upwards on each side of his symbol. The player first giving the correct solution of the problem wins the two cards, and so on till one player has won all the cards.

Apparatus for finishing garments comprises a pair of heated press beds 1, 2, a pair of formers 22, 23 mounted on carriages 24, 25 running on separate tracks 26, 27, means to move the formers 22, 23 alternately from a loading position to a position between the press beds 1, 2 to press garments placed on them and back to the loading position and means to open and close the press beds 1, 2 at the appropriate time to allow the formers 22, 23 to move therebetween and out therefrom after pressing the garments thereon. The tracks 26, 27 are at an angle to each other and the formers 22, 23 are mounted on the carriages so as to be centrally disposed between the press beds 1, 2 for pressing. The carriages 24, 25 are moved by endless chains 28 driven by a motor 33. The press beds 1, 2 are opened and closed by levers 7, links 10, 11 and crank pins 12, 13 on a shaft 14 driven by a motor 37. The motor 33 is stopped by the carriages 24, 25 operating a switch 36 when they reach the pressing position which starts the motor 37 to close the beds 1, 2. The motor 37 is automatically stopped, when the beds 1, 2 have closed, by a switch 40 operated by an abutment 38 on a rotating disc 39 on the shaft 14, which also acts on a relay-operated time-switch to start the motor 37 after a predetermined length of time. It also starts the motor 33 to return the former between the press-beds 1, 2 to the loading point and cause the other former to do the opposite. The abutment 38 operates a second switch 41 to stop the motor 37 when the beds 1, 2 are fully opened. Shutters may be provided moved to close the entrance to the space between the beds 1, 2 when a former is in the pressing position and operated by a control switch preventing starting of the motor 37 unless the shutters have closed that entrance.

Abstract: 380,531. Two-stroke engines. PETERS, J. A., 30, Caldecote Street, Newport Pagnell, Buckinghamshire. July 1, 1931, No. 18962. [Class 7 (ii).] In a radial cylinder engine the cylinders are in two planes, those in one plane being staggered with respect to those in the other; each cylinder is of two diameters, the upper part 5 being the power chamber, the lower annular part 2 a pump chamber. The pump chamber of any one cylinder supplies the power chamber in the next cylinder in order of rotation round the crank ; thus each pump is connected to the power chamber of a cylinder in a different plane. Mixture is drawn in through a port 3 controlled by a slipper 8 on the pump piston, and the transfer ports 4 are opened and closed by the power pistons 7 ; the mixture is drawn from a chamber 17 isolated from the crank case and connected to a carburetter. The pistons in the two planes are connected to cranks at 180‹.

Abstract: 427,936. Filters. HENRY, F. G., 2727, North 13th Street, Philadelphia, U.S.A. June 27, 1934, No. 19032. [Class 46] The liquid filtered inward through an endless belt 32, as it passes round a perforated rotary cylinder 16, is discharged through a hood 20; which extends along the peripheral wall of the drum between the points where the band is looped on and away from it. The band passes also round rolls 29, 31, 26, the apparatus being arranged in a casing 5 with a removable cover 6. The interior of the casing is divided by a vertical wall 9 into a filtering-compartment 13 and a compartment 54 for receiving material separated from the belt by a washing device 46. The liquid under treatment is supplied to the compartment 13 and is maintained therein to the level of the top of the wall 9. The filtrate passes away through the collector hood 20, a discharge leg 23, and a pipe 24. The filter band has metal bound edges with eyelets which engage with sprocket wheels on the ends of the roller 29. The roller 29 is driven from an electric motor by worm reducing gearing. The same motor drives a pump which draws a small amount of filtrate from the bottom of the leg 23 and forces it to a hollow washing shoe 46 the underside of which is perforated and grooved. The band is supported as it passes the washing shoe by a grate 56 formed of bars which converge towards the centre line of the grate and serve to keep the belt in correct position. A scraper blade 52 is associated with the washing device. The solid matter is discharged from the compartment 54 through a valve 63, and liquid separating in the compartment rises through a baffled passage 65 and returns over the wall 9 into the compartment 13. Air under pressure to aid filtration may be supplied to the upper part of the casing.

Abstract: 494,851. Resilient mountings. LISTER & CO., Ltd., R. A., and WILKINSON, B. July 9, 1937, No. 19116. [Class 108 (iii)] A rubber mounting for stationary or car engines &c. comprises a two-part casing surrounding a rubber block to limit the expansion of the rubber under the action of oil or like solvent and spaced apart so that deformation of the rubber under load or by vibration can take place in every direction. As shown, a lug 11 of an engine casing is bored to receive a bolt 14 and a bush 13 of vulcanized indiarubber. The bolt passes through upper and lower cushions 25, 15 of material similar to that of the bush 13 which may be of the kind sold under the Registered Trade Mark " Sinatex." The cushion 15 is enclosed in upper and lower metal cup members 18, 19 which telescope into one another and limit the radial expansion of the cushion when it swells due to contact with oil. Perforations 24 in the rubber allow the rubber to expand inwardly on compression. Oil sealing washers 20, 22 above and below the cups prevent the admission of oil to the rubber. The bolt 14 compresses both cushions to near the elastic limit of the rubber. The bolt head or washer 23 may rest on a concrete foundation 28 or the mountings may be interposed between a chassis and the engine.
