Title: Improvements in or relating to propeller pencils
IPC: B43K21/08
Filed: 1933-04-20
Abstract: 412,376. Pencil holders. BINA, F. C., and BARREY, F. F., 231, Liverpool Road, Islington, London. April 20, 1933, No. 11564. [Class 146 (iii).] In a propeller pencil having a screw action operated by rotation of the screw, the latter is attached to the rotatable pencil head by means of a pin or projection, provided on the screw, or on a member fixed thereto, and which fits into a recess or perforation formed in a tube fixed to the head of the pencil, the pin being maintained in the recess by an external sleeve which fits over the tube. The pin a<1> on the screw a extends through a hole in the tube s, which is preferably split and is of a springy nature so as to enable it to be readily forced over the pin a<1>, and over the tube is fitted a sleeve d held in place by solder &c. The slotted tube k which forms the usual guide for the end b<1> of the lead propeller b is fixed in the screwed member c, which unites the point section p to the barrel f, and is formed with a flange e<1> to engage a shoulder f<1> in the barrel. The tube k is provided with lateral projections k<4> which engage corresponding key-ways k<5> in the member e, thereby preventing rotation of the tube, longitudinal movement of which is prevented by the ends of the slots k<5> and by a washer k<2> which fits on the tube and is held against the enlargement k<3> formed on its end by the screw a. The head h fits friction tightly to the tube s and the space below a rubber r, fitted into the end of the tube, forms a magazine for leads, the base of which is formed by a disc i.

Abstract: 1352352 Drawing tables SPACIO SYSTEM A B 27 April 1971 [27 April 1970] 11604/71 Heading A4H A vertically adjustable drawing board 1 is supported by a parallel motion linkage which includes opposite first and second levers 3, 4 and includes a device for locking the linkage at the adjusted height of the board 1, the device including a guide member 10 carried by one of the levers 3, a link 8 pivoted, as at 7, to the other lever 4 and slidably engaged with the guide member 10, and locking means carried by the guide member 10 which is selectively operated to prevent displacement of the link relative to the guide member thereby to maintain the mutual spacing of the levers 3, 4 and hold the board at its adjusted height. As shown, the locking device comprises a bolt 15 engaged through slots 13 in a pair of members 11, 12 forming the link 8 and a nut 17 engaged on the threaded end of the bolt 15 so that tightening of the nut 17 by an operating handle 18 effects a clamping of the lever 3 between the link members 11, 12. In an alternative embodiment the link comprises a bar which is displaceable in a diametric bore through a rotatable pin, the bar being lockable by a grub screw threaded into a radial bore in the pin. Angular adjustment of the board is permitted by a two part bracket 2, 2' which is lockable in the adjusted position by a clamp screw and slot.

IPC: F21V37/00
Filed: 1918-07-16
Abstract: 120,548. Thym, B. Muller-. Nov. 5, 1917, [Convention date]. Sanctuary lamps.-A sanctuary lamp adapted to bum common vegetable oils is provided with a wick 4 suspended from a point above the flame, the wick being arranged to travel upwards through the oil, so that any crust formed beneath the flame passes up through the flame and is consumed. In the form shown, an endless wick 4, made of asbestos, fire-proofed cotton, or other non-combustible material, passes over wheels 3, 5 respectively carried by a weight 2 and a ring 8 on the oil vessel top. In modifications :-(1) the wheel 5 is replaced by a spirally grooved sleeve operated by clockwork, and (2) the wick is unwound by clockwork from a submerged drum on to an upper drum. A burner, which may be employed, comprises a float 12 provided at the top of a central tubular part 13 with a cap 14; air entering by the holes 16 becomes heated and thus assists the flow of oil through the wick.

Title: Digital counter/divider
IPC: H03K21/00
Filed: 1966-03-17
Abstract: 1,103,286. Electronic counters. MONSANTO CO. 17 March, 1966 [18 Maroh, 1965], No. 11869/66. Heading G4A. At least the first two stages of a 4-stage biquinary counter are J-K flip-flops. The other stages may be of R-S type. Both J-K and R-S types can be set or reset by an input on its set or reset terminal, respectively, but a J-K flipflop reverses if a 1 signal is applied to both of its input terminals. As shown all stages are dependant also on a clock input for operation. Stage A reverses to successive pulses on 14 when both its set and reset terminals are marked by a control 15. Alternate pulses are directed by #A to clock inputs of stages B, C, D, which are arranged through the feed-back shown to operate to a radix 5. The true and complementary outputs of the stages are combined in logic circuits (Figs. 4, 5, not shown) to produce a binary-coded decimal or true decimal indication. The code is shown in Fig. 3. Carry is taken from D. In a frequency-divider the clock pulses to stages B-D are provided from output A and the first pulse produces a carry from B. In a multi-denominational circuit therefore division begins with an output pulse.

Abstract: 1,100,120. Hoses. DYNAMIT NOBEL A.G. 19 March, 1965 [21 March, 1964], No. 11909/65. Heading F2P. A process for manufacturing a flexible, fabricreinforced pressure hose comprises introducing an inner tube of thermoplastic plastics material into a fabric casing manufactured from synthetic or natural fibres or filaments coated with thermoplastics material, expanding the inner tube against the inner walls of the casing using compressed air, uniformly heating the exterior of the casing whilst maintaining contact between the tube and casing so that the inner tube is softened and becomes bonded to the interior casing walls, and subsequently cooling the hose produced. The thermoplastic material is elastomeric and is preferably of plasticized polyvinyl chloride, polyurethane, or a mixture thereof. The casing may be heated by air circulating through surface-heating ducts or by mounting the casing on rollers and passing the same through a double-walled tube heated by pumpcirculated water at a controlled temperature. The fibres or filaments of the easing may be coated, preferably during their manufacture, with the same thermoplastic forming the inner tube to produce a homogeneous inner tube/ casing bond and an abrasion-resistant covering.

Title: Improvements in or relating to the froduction of hydrogen containing gases
IPC: C01B3/38
Filed: 1946-04-18
Abstract: A process for manufacturing a hydrogen and carbon monoxide-containing synthesis gas comprises reacting together, in the presence of a catalyst such as nickel or nickel on a supporting material, a mixture of steam, carbon dioxide <PICT:0616710/III/1> and a normally gaseous hydrocarbon, preferably natural or refinery gas, methane, or a hydrocarbon containing 1 to 4 carbon atoms per molecule, say, at 1300-1500 DEG  F., and 15-150 lbs. per sq. inch, to give a product containing carbon monoxide, hydrogen, carbon dioxide, steam and unchanged hydrocarbon, then passing this product at a higher temperature through an oxidizing zone where it contacts with a free oxygen-containing gas, preferably 0.25 to 0.45 moles. of oxygen per carbon atom, to convert the remaining hydrocarbon to carbon monoxide and hydrogen.  Alternatively, the normally gaseous hydrocarbon may be a narrow boiling range gasoline fraction when a non-coking catalyst is used such as one containing nickel oxide, alumina or magnesia with a major portion of aluminous cement.  As shown, natural gas, carbon dioxide and steam, after desulphurization if necessary, are heated in p  preheater 10 to 1000 DEG  F. and pass to reformer furnace 13 containing catalyst tubes 14, heated by burners 35a, b, &c.  The product passes to oxidizer 20 where air or oxygenated air containing 21-100 per cent oxygen preheated to 500-1000 DEG  F. by passage through the reformer furnace 13 is supplied through manifold 22, which converts unchanged hydrocarbon at a minimum temperature of 1600 DEG  F. in contact with the beds, G, of catalyst which may be the same as that in the reformer tubes.  The product, after cooling in boiler 30 to about 800 DEG  F., may be used for hydrocarbon synthesis, or to produce hydrogen.  In an alternative arrangement part of the hydrocarbon is byepassed directly to the oxidizer, while part of the carbon dioxide and steam may be fed through a heat exchanger in the top of the oxidizer before passage to the reformer furnace.  The oxidizer may contain a fluidized bed or a stationary bed or beds of catalyst or a series of such oxidizers may be used.
