Title: Internal shoe-drum brake mechanism for vehicles
IPC: F16D51/52
Filed: 1955-03-14
Abstract: 764,680. Internal shoe-drum brakes. MARTIN, F. M., MARTIN, R. M., and MARTIN, M. M. March 14, 1955, No. 30677/55. Divided out of 35996/53. Class 103 (1). An internal shoe-drum brake is operated by actuation of a hydraulic brake cylinder 15 which acts upon expander levers 16 pivoted to the webs 21 of brake shoes 22 by pins 20. The upper ends of the levers 16 are adjustably secured by links 25 to anchor members 27 and the upper ends of the shoes 22 are also pivotally connected thereto by links 30 at pins 29. This arrangement of mounting the shoe is claimed to produce even wear of the lining and enables the friction surface to be extended over as much as 95 per cent of the drum area. Automatic wear adjustment devices as shown in Figs. 4 and 5 are fitted to both shoes. These comprise bifurcated levers 33 having pins 19 extending through slots 18 in the levers 16 and being pivoted to plates 35 by pins 34. When the levers 16 are expanding the shoes are able to move the plates 35 as well as the levers 33 but when the brake is released plates 35 are held fast by friction with the back-plate as a result of pressure by spring 37, and the brake shoes are set to a clearance determined by the distance between nut 48 and stop 47 on member 35.

Title: Improvements relating to smelting furnace assemblies and the method of operating them
IPC: C21C5/56
Filed: 1964-08-04
Abstract: <PICT:1071352/C6-C7/1> The flue gases from a melting furnace, heated by the combustion of fuel in technically pure oxygen, are passed to a tank or tanks to preheat the raw material for the next charge, contained therein. The fuel together with an insufficient quantity of a 95% oxygen composition for complete combustion is fed via burner 2 to tiltable furnace 1, the exhaust gases produced passing through a Y' branched, refractory lined open ended flue 3 into tapered tubular tanks 4, having an inlet to outlet area ratio of between 5 to 1 and 2 to 1 to preheat the raw material for the next charge. Additional preheated oxygen-enriched air is provided before the tanks 4 to complete combustion of the fuel.  On completion of the melting of the charge, burner 2 and flue 3, now covered by end covers 11 to prevent cooling, are withdrawn, the furnace 1 tapped and the preheated burden skip charged from the tanks 4 by crane lifts 12, 13 to the furnace. Burner 2 and flue 3 are then replaced and a new tank 4 containing a fresh charge to be preheated inserted between flue 3 and abutment 17 leading to the exhaust system through bellows 18 which take up any expansion. During the tapping and charging the Y flue 3 may be repaired by spraying.  In a second embodiment Fig.4 (not shown) a furnace fitted with a swivelable cover plate which may be removed as well as the burner and flue, or a cover plate secured to the flue to be removed with it to facilitate charging is disclosed.  In this latter case the furnace may be mounted on wheels.  A pressure gauge is mounted in the flue 3, the signal from which is used to control the induced draught to within \sB3 mins w.g. of a desired value.

Filed: 1945-11-16
Abstract: 622,206. Grates; gas-producers. MARTIN, R. M. L. Nov. 16, 1945, No. 30853. Convention date, June 27. [Classes 51 (i) and 55 (i)], A grate, particularly for use in an inclined position, has air passages which are separated from one another and have restricted inlets so that the air meets the fuel with reduced velocity, the carrying of dust being thus avoided. The grate shown in Figs. 6 - 8, is formed of bars 8, shown as spaced to indicate that they are unfinished castings, the inlets 5 of the air passages leading to expansion chambers 6. The bars may be of ring form. In the application of the grate to a gas producer, Fig. 9, the air supply for combustion is preheated by being passed through pipes 16 in a member 15 which protects the gas outlet 14 from the descending fuel. Shutters 18 in the fuel shoots 19 separate the hopper 15A from the gasproducing space. Ashes are removed by a rake 13 working over a plate 12.

Patent GB-440057-A (GB)
Title: Improvements in or relating to cigarette paper book-making machines
IPC: B42C19/06
Filed: 1934-10-30
Abstract: 440,057. Packeting cigarette-papers. STRAUS, H. H., 345, West 40th Street, New York, U.S.A. Oct. 30, 1934, No. 31136. [Class 94 (i)] In a machine for making up packets of cigarette papers, a continuously-fed wide band of paper to which adhesive is applied in a longitudinal stripe is slit along the centre line of the stripe into strips which are then superposed and folded about with wrapping material, appropriate lengths being severed to form the individual packets. The paper band is fed from a roll 15 around a tensioning roll 36 and guide rollers 23-25 and over the spaced orifices of an adhesive-supplying pipe 27 to a large roller 21 provided with a shield 22. The roller 21 may be heated internally or the shield 22 may be heated in order to dry the adhesive. After leaving the roller 21, the band is fed around a series of guide rollers 38-45 to a roller 48 against which are urged a number of cutting discs 51 spaced along a shaft. The band is thus cut into strips 33 along the lines 32, 34, Fig. 4, along the centre of each stripe of adhesive and half-way between adjacent stripes. Alternate strips are then fed upwardly and downwardly to rollers 54, 55. Each strip 33 from the roller 54 passes downwardly under a pin 58 located vertically beneath it, being given a quarter turn, and is then fed to the left (Fig. 5), so that a group of superposed strips is formed. In the same way, each strip from the roller 55 passes upwardly over a pin 59 and is fed to the right, thus forming a second group of superposed strips. Each group of strips passes over a roller 60 together with a strip 62 of wrapping material which is folded around the strips by a stationary folder 63, and the enclosed strips are fed by transverse bars 67 carried on sprocket chains 66 to the cutting apparatus. This comprises an anvil 115 which co-operates with a blade 119 on across-head 118 supported by straps 121 from discs 122 eccentrically mounted on a shaft 123 which is driven at a speed suitably proportioned to the speed of the paper feed to sever appropriate lengths of the enclosed strips to form packets 157, which are led away by a travelling belt 155. The operator is able to adjust the speed of the shaft 123 and to determine the position of the cuts relative to markings on the wrapping material. The sprocket chains 66 also are driven through variable speed devices.

Title: Nickel-catalysed hydrogenation processes
IPC: B01J25/04
Filed: 1949-12-07
Abstract: Organic compounds are hydrogenated in the presence of a Raney nickel catalyst at 20-180 DEG  C. using hydrogen containing 0.001-5 per cent by volume of carbon monoxide, and the catalyst is reactivated by being maintained at least periodically at 85-180 DEG  C., preferably in the presence of hydrogen.  If the hydrogenation is carried out at 85-180 DEG  C. no separate reactivation step is necessary.  The catalyst is preferably used in liquid suspension, for example as described in Specification 649,554.  Unsaturated hydrocarbons, e.g. styrene or alkyl styrenes, unsaturated aldehydes and ketones, and saturated aldehydes and ketones, may be hydrogenated.  Examples describe the preparation of (a) isopropyl benzene by the continuous hydrogenation of alpha-methyl styrene at 85-175 DEG  C. using a suspension of the catalyst in isopropyl benzene or a mixture of isopropyl benzene and alphamethyl styrene; the process is also performed batchwise at 50 DEG  C. with periodic reactivation of the catalyst at 150 DEG  C.; (b) butyraldehyde by the continuous hydrogenation of crotonaldehyde at 114-160 DEG  C. using a suspension of the catalyst in butanol; this hydrogenation is also carried out batchwise at 25-60 DEG  C. using the catalyst suspended in a mixture of crotonaldehyde and 2-methyl-2 : 4-pentane diol, and raising the temperature periodically to 150 DEG  C. to distil off butyraldehyde and to reactivate the catalyst; (c) propionaldehyde by the hydrogenation of acrolein vapour at 149-163 DEG  C. using the catalyst suspended in dibutyl phthalate or ethyl hexanol; (d) 2-methyl-2 : 4-pentane diol by the continuous hydrogenation of diacetone alcohol at 100-110 DEG  C., or by a batchwise process at 50 DEG  C. with reactivation of the catalyst at 105 DEG  C.; (e) methoxy-propanol by the continuous hydrogenation of vaporized methoxy-propionaldehyde at 110-180 DEG  C., using the catalyst suspended in methoxy-propanol or dibutyl phthalate.ALSO:Organic compounds are hydrogenated in the presence of a Raney nickel catalyst at 20 DEG -180 DEG C using hydrogen containing 0.001-5 per cent by volume of carbon monoxide, and the catalyst is reactivated by being maintained at least periodically at 85 DEG -180 DEG C, preferably in the presence of hydrogen.  If the hydrogenation is carried out at 85 DEG -180 DEG C no separate reactivation step is necessary.  The catalyst is preferably used in liquid suspension, for example as described in Specification 649,554, [Group IV(b)].  Unsaturated hydrocarbons, e.g. styrene or alkyl styrenes unsaturated aldehydes and ketones, and saturated aldehydes and ketones, may be hydrogenated.  Examples describe the preparation of isopropyl benzene from alpha-methyl styrene, butyraldehyde from crotonaldehyde, propionaldehyde from acrolein, 2-methyl-2:4-pentane diol from diacetone alcohol, and methoxy-propanol from methoxy-propionaldehyde (see Group IV(b)).

Abstract: 1,221,300. Remote control of vehicle door locks. JOSEPH LUCAS (INDUSTRIES) Ltd. 21 June, 1968 [7 July, 1967], No. 31450/67. Heading E2A. All the doors of a vehicle, having at least four doors, are adapted to be locked or unlocked simultaneously by operation of the driver's key in either front door lock, through the operation of a set of locking solenoids 11-14 and a set of unlocking solenoids 21-24, respectively, the circuits to these solenoids including, in addition to key-operated switches 28,. 29 for the respective front doors, a set of solenoid-operated switches 15-18, all of these switches being of two-way type and the arrangement being such that when switch 28 (as shown) or 29 is moved to the "lock" position the consequent energisation of the looking solenoids 11-14 causes switches 15-18 to change over, after a delay caused by a mechanical interlock (not shown), from the position shown to that in which the solenoids 11-14 are de-energised and unlocking solenoids 21-24 are placed in circuit. The latter circuit, however, is not completed by the other of the switches 28, 29 (29, as shown) since this switch is changed over mechanically during operation of the respective lock before switches 15-18 change over, owing to the mechanical interlock referred to above. The operation of the mechanism when switch 28 or 29 is moved to "unlock" position is therefore analogous to the above described operation.
