Title: Process for the production of glass bodies, particularly glass shells, with an indrawn rim
IPC: C03B19/04
Filed: 1935-09-07
Abstract: 459,200. Glass manufacture. WURTTEMBERGISCHE METALLWARENFABRIK, and DEBACH, H., 19, Eberhardstrasse, Geislingen - Steige, Wurtemberg, Germany. Sept. 7, 1935, No. 24988. [Class 56] A hollow glass article with an inturned rim is shaped by centrifugal force, as in the production of crown glass. A hollow body 1, Fig. 2, is blown on a pipe 2, and after a foot portion 3 has been applied, it is attached to a punty 4 and is cracked-off at 5 from the pipe 2, all in the known way. The upper part of the body 1 is then heated around the opening 6 left by the pipe, and the glass is turned inwards in the usual way to form an inwardlydirected rim 7, Fig. 3. Next, the body is reheated at the upper part 8 in front of a glory-hole, and is given its final shape by spinning the punty 4 as in the production of crown glass, so that the glass expands laterally under the action of centrifugal force, as shown in Fig. 4. During the reheating, the rim 7 is not so much exposed to the heat as the part 8 and remains cooler and stiffer, so that it does not spread outwards during the spinning.

Title: Improvements in apparatus for filtering gases or liquids
Inventor: BARKER FRED
IPC: B01D29/00
Filed: 1948-09-29
Abstract: 666,983. Filters. STEPHENS BARKER & CO., Ltd., BARKER, F., and STEPHENS, C. A. Dec. 23, 1949 [Sept. 29, 1948], No. 25351/48. Class 46 [Also in Group XXVIII] A filter to the casing of which liquid is supplied by a pump is provided with valve means whereby when the filtering operation is being started up and the pump is delivering the liquid at a pressure below normal working pressure normal flow is cut off and reverse flow permitted, but when full operational pressure is attained the valve is moved to cut off reverse flow and permit normal flow. Liquid passing at L' into a casing top L at low pressure from a pump at the beginning of a filtering operation flows into the upper end of a slidable valve tube F urged to the top of a recess L<SP>5</SP> (left-hand side of the Figure) and thence through ports P above a partition F<SP>2</SP>, ports B in the casing top L, and a cavity L<SP>6</SP> into a space A<SP>2</SP> around a filter screen A. Liquid together with impurities forced out from the inside of screen A passes through ports K in a cylindrical extension L<SP>9</SP> of the casing top L and into the tube F through ports Q below the partition F<SP>2</SP>. This reversely-flowing liquid is at too low a pressure to flow upwardly from the space A<SP>2</SP> to the filtered liquid outlet L<SP>8</SP>. As the pressure of the incoming liquid builds up to. e.g. more than 5 lbs. per sq. in. a valve N is depressed against the upthrust of a spring N<SP>2</SP> and liquid is admitted from the space A<SP>2</SP> into a sump H and forces upward a piston C sliding on the tube F and provided with a ring G which scrapes any remaining impurities from the inside of the screen A. These impurities together with liquid above the piston are discharged via ports K and Q down the tube F. When full operating pressure is reached the incoming liquid acting on the partition F<SP>2</SP> forces the tube F downwardly against the upthrust of a spring J engaging a shoulder F<SP>1</SP> to the position shown on the right of the Figure. The ports B and Q are obturated by the tube F and by the cylindrical extension L<SP>9</SP> respectively so that liquid to be filtered passes to the inside of the screen A. The piston C is forced downwards and the space A<SP>1</SP> becomes filled with liquid which flows outward into the space A<SP>2</SP> and thence to the outlet L<SP>8</SP>. Any sludge scraped from the inside of the screen A during the descent of the piston is deposited in the sump H.

Title: Improvements in or relating to projectiles
IPC: F41H13/00
Filed: 1939-09-11
Abstract: 532,578. Projectiles. WELLCOME, H. Sept. 11, 1939, No. 25569. [Class 9 (i)] A "bolas" projectile particularly for use against aircraft, comprises a series of weights connected by wires which are twisted together, the cable thus formed being helically coiled within the shell. The weights may be separate elements fitted, preferably non-rotatably, in the shell, means being provided for increasing the rotational speed of the weights over that of the shell ; or, they may be constituted by sections of the shell casing itself. To prevent undue twisting of the wires as the weights rotate, swivel connections are provided. In the form shown in Fig. 1, the looped ends 7B of the series of wires 7 are connected to plugs 9K which are rotatable in the weights 9. The firing- charge 4 for discharging the bolas is separated from the latter by a plate 12 and segments 12B, these and the weights being formed with driving- lugs engaging bands on the interior of the shell 1 to give additive rotation of the " bolas" on discharge from the shell-casing. The bore of the latter diverges towards the head 3A where the wires are grouped by a clip 17 supported by a series of Z-shaped brackets 8H which are spread by centrifugal force to release the clip. Fig. 14 shows a modification in which the weights connected to the hubs of the wires 31 form segments 25 of the actual shell-casing connected by the base-cap 27 and nose 26, these parts being keyed together to prevent relative rotation. Fracture of the shell, to release the weights, is controlled by a time fuze 28 operating a powder charge 36. In all cases, the wires used may be of round, or streamlined section.

Patent GB-1129946-A (GB)
Title: Control system for refrigerating apparatus
IPC: F25B49/02
Filed: 1967-06-02
Abstract: 1,129,946. Time switches. RANCO Inc. 2 June, 1967 [15 June, 1966], No. 25695/67. Heading H1N. To ensure that a refrigerator compressor motor cannot be re-energized until a predetermined time interval has elapsed following deenergization a control device comprises a change-over contact normally latched in engagement with a first "fixed" contact in series with the motor circuit and tripped open when the motor circuit is opened, being subsequently closed by a cam driven through gearing by a synchronous timer motor which is energized via a second "fixed" contact engaged by the changeover contact when in its unlatched condition. In a first embodiment (Fig. 2) a solenoid 56 is connected in parallel with the compressor motor (15, Fig. 1, not shown) so that armature 55 is lifted against spring 62. When the motor (15) is de-energized the armature 55 is released and its kinetic energy causes projection 60 to impinge on pivoted latch 48 (as in Fig. 3, not shown), opening contacts 35, 36 in the compressor motor circuit and closing contacts 35, 37 in the timer motor circuit. Cam 31 is then driven by the timer motor (30, Fig. 1, not shown) until rise 33 lifts contact 37 and hence contact 35, allowing latch 48 to restore (Fig. 4, not shown). An insulating spacer 42 keeps contacts 35, 36 open until contact 37 drops off rise 33 whereupon the condition shown in Fig. 2 is re-established. A revolution of cam 31 may take five minutes, for example. In a second embodiment (Fig. 6) a solenoid 140 is connected across certain protective switches (103, 104, Fig. 5, not shown) in series with a compressor motor (100) such that it is energized when either of these switches opens. This causes armature 137 to impinge on adjustment screw 136 of pivoted lever 132 and displace the end 125 of resilient blade 121 carrying changeover contact 120, which is inherently biased towards fixed contact 114 in the timer motor circuit but latched as shown by a relatively stiff member 126 overlying projection 124. Displacement of end 125 allows contact 120 to disengage contact 115 in the circuit of the compressor motor and solenoid 140 and energize the timer motor (111) via contact 114. Cam 110 is thus driven until rise 112 lifts member 126 over projection 124 (Fig. 8, not shown), and the drop 113 then restores the contacts to the position shown.

Title: Pneumatic control apparatus for controlling the automatic sequential operation of machines required to follow a predetermined operating cycle
IPC: B23Q15/00
Filed: 1955-09-12
Abstract: 813,381. Programming for machine-tools. MOOSMANN, A. Sept. 12, 1955 [Sept. 13, 1954], No. 26089/55. Class 83 (3). A milling, turning or boring machine tool, or a textile or packing machine, comprises a tape formed with projections acting on compressedair valves controlling the machine. The valves have a portion 8 contacted by a lever such as 18, Fig. 1. Movement of the lever lifts the portion 8 to raise a seating, 4 and allow air to pass from a passage 3, through a chamber 12, to a passage 13 leading to the operating means of the machine tool. When the portion 8 is released, air is exhausted from the passage 13 through a bore 11, openings 15 and a passage 17. Two endless steel tapes 23 are mounted on a common roller 22, which can be withdrawn by a handle 28, the tapes having rivets 24 positioned in selected holes therein to operate the levers 18. The roller 22 is advanced by an air-operated toothed piston 36 engaging a ratchet wheel 33. The piston is operated by movement of the machine-tool parts, via a centralizing controller 48, Fig. 5. Impulses received by the controller through unions 47 actuate pistons 50 to move a master piston 53, 54 to operate a valve 55, which directs air to the piston 36. Movement of the piston 36 not only advances the tape but also operates a valve to direct air to an inlet 59 of the centralizing controller, causing racktoothed pistons to move and rotate the pistons 50. Rotation of the pistons 50 so positions flats 64 on flanges 52 thereof as to allow the master piston 53, 54 to return to its initial position whilst the actuated piston 50 remains in its forward position. The piston 50 returns to its initial position when pressure in its line 47 is released, as by a carriage of a lathe moving away from a stop. The levers 18 can be actuated manually by cams 73 or levers 67. In operation, a cam 73 is operated manually to start the cycle of operations of a lathe turret slide. The cam actuates a lever 18 to cause advance of the tape. A projection on the tape causes engagement of a clutch to feed the slide at high speed. In its movement, a cam on the slide actuates a valve to cause the tape to advance a further step, and a further clutch is operated to move the slide at feed-speed until a second cam on the slide causes a further movement of the tape. The slide is then returned at high speed. The cycle is repeated for each turret setting.
