Patent GB-116161-A (GB)
Title: An Improved Lathe for Operating upon Shells.
Inventor: PHILIP WILLIAM LITTLEJOHN
IPC: B23B5/40
Filed: 1917-06-08
Abstract: 116,161. Philip, W. L. June 8, 1917. Lathes; chucks.-Consists in a lathe primarily designed for turning large shells and boring the fuse hole therein. The shell is carried on an expanding and driving mandrel secured to the lathe spindle. The mandrel has expanding centring dogs or projections i, Fig. 3, at the forward end, and centring and driving feathers i' which engage in slots in the shell at the rear end. The shell is forced on to the mandrel by the tailstock spindle which is actuated by hydraulic or other fluid-pressure. The saddle n is traversed by fluid-pressure, and carries four slide-rests o also actuated by fluid-pressure and provided with automatic stops. One rest o at the back and one in front carry tools q for rough turning the cylindrical part of the shell, and a screw-fed rest in front carries a finishing tool r for the cylindrical part. The other back rest o carries a gang of tools s for rough turning the nose, while the other front-rest o carries a ncse-finishing tool t. The fluid-pressure actuated rests are preferably fed by high-pressure fluid controlled by inlet and exhaust valves, while ths return movement is effected by a constantly-acting lower pressure. The attachment u for boring the fuse hole is carried on a swinging arm u<1> and is fed up by the saddle. The drilling attachment is moved into and away from the working position by a handlever u<2>, Fig. 5. The fuse-hole is bored first, during which operation the lathe is run at a high speed and, after this operation is completed, the boring-device is swung clear, a centre is placed in the fuse-hole, and the tailstock is moved up to support and centre the work during the subsequent operations. The lathe is provided with a brake by which it can be stopped quiekiy.

Patent GB-889913-A (GB)
Title: Power control unit for sewing machines
IPC: D05B69/12
Filed: 1960-03-08
Abstract: 889,913. Sewing machines. SINGER MANUFACTURING CO. March 8, 1960 [March 10, 1959], No. 8210/60. Class 112 [Also in Group XXIV] When a sewing machine is started a clutch is engaged for part of a revolution of its driven element so as to close a work clamp whereupon the clutch is disengaged, and is re-engaged for the remainder of the revolution upon stopping the machine in order to open the clamp. The clutch comprises a continuously driven input pulley 63 formed with a clutch surface 64 cooperating with a clutch disc 65 fast on an axially movable shaft 61 biased to the engaged position by spring 66 and shifted axially to disengage by a finger 69 on a collar 67 fast on the shaft riding up a cam surface 74 on a control member 70, in which position the finger abuts a stop 73 to prevent further movement of the shaft 61. The control member 70 is pivotable about a pin 71 to a second position in which a cam 74<SP>1</SP> and stop 73<SP>1</SP> disengage the clutch and stop the shaft. The shaft 61 carries a crank connected by a linkage to a clamp operating lever 21. In order to start sewing a rock shaft 26 is actuated by a foot treadle and has an arm 29 having a lost-motion connection with a lever 22 which initiates the cycle of stitch forming operations of the machine. While the lost-motion is being taken up the rock shaft actuates through an arm 97 and rods 93, 91 the control member 70, removing cam 74<SP>1</SP> and stop 73<SP>1</SP> from the path of the finger 69 so that the clutch engages and shaft 61 rotates through half a revolution to close the clamp whereupon the finger rides up the cam 74 and disengages the clutch. When the starting lever 22 is released at the end of a cycle of sewing, the rock shaft 26 is returned by a spring, and control member 70 is returned to its initial position, so that the clutch engages and shaft 61 rotates for the further half revolution to open the clamp whereupon the finger rides up the cam 74<SP>1</SP> and abuts stop 73<SP>1</SP>. If automatic opening of the clamp is not desired the mechanism may be rendered ineffective by means of a keeper 101 having a hooked extremity 102 which is slid along the arm 29 until the hook embraces a rod 30 connected to the starting lever 22 and retains the rod in the upper end of a lost-motion slot so that complete return of the rock shaft 26 is prevented. The mechanism is therefore locked in the clamp closed position. In a modification (Figs. 7-10 not shown) the member 70 is formed with a single cam and stop and the collar has several fingers at different radial distances from the shaft 61 and spaced angularly around the collar. This construction has the advantage that the fingers can be arranged in any desired angular relation whereas with the first construction the stops must be arranged substantially diametrically opposite each other. Furthermore the first construction is limited to two stop positions while in the modified form more than two fingers may be provided.

Title: Chemical process for the manufacture of alkaline earth metals and alloys thereof
IPC: C22B26/20
Filed: 1942-06-17
Abstract: 574,092. Alkaline earth metals; alloys. BRITTON, J. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 17, 1942, No. 8267. [Class 82 (i)] Calcium or a calcium-rich alloy is made by reacting on an anhydrous calcium halide melt with an alkali metal in an atmosphere inert to calcium, the halide being present in excess which may be three to five or more times the equivalent of the sodium. If a calcium alloy is being made the other element, which may be magnesium, aluminium, zinc, silicon, tin, copper, lead, antimony, cadmium, or bismuth, is added to the mixture, for example as chloride. The product contains small amounts of alkali metal which may be removed by distillation or by treating the molten alloy with a fused calcium halide or halides. In an example, calcium chloride is melted in a steel pot provided with a lid and stirrer ; the air above the melt is displaced with nitrogen and sodium is added, the nitrogen being then displaced with argon. Heating is continued at 750-900‹ C. for about an hour with stirring. On cooling, a layer of calcium, or of an alloy of calcium containing some sodium is obtained over a solidified salt layer.

Abstract: 865,081. Supporting vehicle lamps. SOC. POUR LA FABRICATION DES PROJECTEURS ELECTRIQUES MARCHAL. March 11, 1959 [March 14, 1958], No. 8346/59. Classes 75(3) and 75(4). [Also in Group XXV] A vehicle headlamp comprises an optical assembly adapted to be mounted in a support, e.g. a casing mounted in an opening in the body of the vehicle, by a plurality of attachment devices distributed on the periphery of the assembly, each attachment device consisting of a support member and a resilient gripping device in which it is engaged. The headlamp 4 may be provided with lugs 5 in each of which is engaged an adjusting screw 6 having a pointed end 6a behind which is a groove 6b. Resilient fixing devices 7, e.g. of rubber, carried by the vehicle body in positions corresponding to the screws 6 have openings into which the ends 6a of the screws are inserted. Alternatively, the screws may be mounted on the body and the resilient devices on the lugs 5. Some of the screws 6 may be replaced by fixed members having similar heads and grooves. To provide for re-orientating the headlamps on changing over from a country where left-hand driving is used to one where right-hand driving is the rule, the resilient devices may be provided in pairs mounted side by side and spaced at the appropriate angle, or two spaced resilient devices may be carried on a common. base. To avoid errors in mounting, the devices not to be used may be closed by plugs or screws. The provide for axial adjustment in the position of the headlamp, the screws may have two grooves or the resilient devices may have an internal rib providing a second position in which the groove can be engaged. Where several lamps are mounted in an assembly, mounting plates having sets of holes to receive the resilient devices may be provided. The resilient devices may serve also to reduce vibration of the lamps.

Filed: 1928-03-21
Abstract: 287,507. Naamlooze Vennootschap Soc. voor Chemische Industrie Katwijk. March 22, 1927, [Convention date]. Theobromine is extracted from natural materials such as cocoa fruits by intimately mixing the ground material with a large excess of an alkaline earth hydroxide (including magnesia), adding such a quantity of water that the mixture maintained its dry appearance, and then, after leaving the mixture to itself for some hours if practicable, adding water to make a solution of the theobromine salt of the desired concentration. The mixture is then filtered, and the theobromine is recovered by decomposing the salt by carbonic or other acid and separating in the known manner. The water employed in one or both stages may be warm, 70‹ C. being mentioned in an example.
