Title: Improvements in apparatus adapted for the solvent extraction of oils, fats and resins from divided solid matter containing the same
IPC: C11B1/10
Filed: 1943-02-25
Abstract: 569,496. Extraction of oils, fats, and resins. DINLEY, C. F. Feb. 25, 1943, No. 3116. [Class 91] Apparatus for the solvent extraction of oils, fats or resins from divided solid matter containing or bearing such substances comprises a horizontal channel, means for continuously introducing liquid solvent to flow along the channel to an outlet arranged, so that free space is left above the solvent level in the channel, a conveyor in the channel for advancing the solid matter, introduced into the channel, counter to the flow of the solvent, this conveyer having feed elements extending above the solvent level, and a lift tube through which the solid matter is withdrawn from the channel by means of a conveyer arranged to have a greater rate of throughput than the channel conveyer. The apparatus is particularly adapted for the extraction of oil from divided vegetable material such as soya bean meal, using a solvent such as trichlorethylene, but may be employed for removing adhering oil from impervious materials such as metallic filings, small scrap metal and small metallic machine parts. The channel conveyor may be an Archimedean screw, but chain or bucket conveyers may be used in lieu. In Fig. 9, soya bean meal is fed continuously through spout 3 into the closed horizontal 'extraction channel 5 of U-shaped cross-section. The screw conveyer 15 progresses the meal through the extraction channel and on reaching the end of the channel, the oil-free meal is continuously withdrawn to a drier by means of another screw conveyer 29. The rate of feed of the meal into the extraction channel and its rate of travel along the conveyers 15 and 29 are progressively greater so that the meal is kept in a loose condition throughout. The solvent enters the extraction channel through the pipe 10 and passes along the channel in countercurrent to the meal. Oil-bearing solvent leaves the channel by pipe 12 and passes to a still for separation of oil from solvent. Details of the construction of both drier and still are given.

Title: Detonator fuse for shells
IPC: F42C1/04
Filed: 1920-02-04
Abstract: 162,111. Semple, J. B. Feb. 4, 1920. Projectile fuzes.-Relates to percussion fuzes of the kind described in Specification 133,357 wherein a detonation transmission passage, filled with detonating composition, is normally interrupted, but is completed by the relative movement of parts of the fuze after discharge. According to the present invention, the passage is completed by the movement of the percussion pellet on impact, or by the inward movement of the impact plunger in the case of a direct-action nose fuze. Fig. 2 shows a nose fuze with an impact plunger normally held at safe by a centrifugally-released tape 9. The detonation transmission passage d, e, filled with composition, is arranged partly in the plunger and partly in the body of the fuze, the two portions of the passage being caused to register only on impact. Fig. 3 shows a base fuze with a centrifugally-armed percussion striker 8, shown in the safe position in Fig. 4, pivoted in the percussion pellet 2. The detonation transmission passage d, e from the percussion cap a includes a primed hole f in the striker, and the air-gap be tween the pellet and the front end of the fuze body. The air gap is closed when the pellet moves forward on impact, and the hole f is aligned with the transmission passage by the arming of the striker.

Patent GB-1357002-A (GB)
Title: Locking devices
IPC: E05C19/00
Filed: 1971-01-29
Abstract: 1357002 Automatic catches; stud and socket fastenings E G LINDSEY 21 Jan 1972 [29 Jan 1971] 3525/71 Headings E2A and E2B A locking device comprises an elongate or peg member 11, Fig. 1, a hole 13 extending longitudinally and obliquely therethrough, a pin 12 movable in the hole, and means, e.g. a scaffold pole 10, rendering the pin captive, whereby in use the peg member may project through an aperture in another member, e.g. a bracing bar 25, Fig. 2, and be retained there by the pin projecting on both sides of the other member 25. From another aspect, an assembly comprises an elongate or peg member 11, Fig. 2, extending through an aperture in another member 25, these members being retained in this relative disposition by a captive pin 22 extending obliquely through the members with the ends of the pin projecting one each side of both members. As shown in Fig. 1, the peg 11 having the oblique hole 13 is welded with the hole orientated as shown to a scaffold pole 10 in the upright position shown. The pin takes the form of a length of spring wire 12, 14, 16 having the shape shown. Before the pin can occupy the position shown, sufficient space must be provided between the pole 10 and the top of hole 13 for the pin to have the end 15 fitted at the top of the hole, with parts 16 and 14 (16 above 14) above the peg 11. The pin is then inserted until part 14 meets the top surface of the peg, after which the pin is rotated about its own axis until free end 16 snaps past the lower surface of peg 11. The pin is now captive. The apertured end of a cross-bracing bar, (see 25, Fig. 2), is then slid on to peg 11, contacting end 15 of the pin and thereby pushing the pin upwards in the hole until end 15 is flush with the lower end of the hole. When the bracing-bar has passed the lower end of the hole, the pin drops back to retain it.  In Fig. 2 there is no snap action, and the pin must be fitted before the peg 11 is welded to the pole. Loop 20 is deep enough to permit end 22 to be introduced at the top of the hole, and the loop progressively encompasses that end of the peg which is to be welded as the pin is slid downwards without rotation. After the welding, the pin is captive. Bracing- bar end 25 is applied as before. In Fig. 4, end 33 of pin 32 may be bent over after the pin has been inserted upwardly, peg 30 being already welded to pole 10. Alternatively, pin 32 in its finished shape may be inserted before peg 30 is welded to the pole. In either case, the clearance between the top of hole 31 and pole 10 must be such that the pin is captive. Also in Fig. 4, when a bracing bar is in position, the pin may be raised and end 33 accommodated in a recess 34 to retain the pin in the "up" position. If this is done at both ends of a bracing-bar, the bar may be simply removed in dismantling the scaffolding. The invention may also be applied to gate locks and vehicle tailboard locks.

Abstract: 1,031,715. Inverting; control of A.C. motors. PLESSEY CO. Ltd. Jan. 31, 1963 [Jan. 31, 1962], No. 3739/62. Headings H2F and H2J. A motor supply and starting circuit comprises an inverter 1 of the kind which utilizes thyratrons or silicon controlled rectifiers and is self-commutating, which inverter feeds an induction motor 3 from a D.C. supply 2, the circuit including temperature sensitive elements 4 in the supply lines to the motor to ensure proper commutation in the inverter on starting. Without the resistors the motor on starting presents a lagging power factor which has the effect of reducing the " turning off " time of the inverter elements below the lowest permissible level for proper commutation. The temperature sensitive resistors present a high resistance on starting to overcome this effect, the resistance falling as the resistor temperature rises due to load current. Resistors 5 and 6 are included to adjust the resistance/time characteristics of the resistors 4. Single phase or polyphase arrangements are envisaged.

Title: A supply system for fluorescent lamps
IPC: H05B41/232
Filed: 1961-02-01
Abstract: 936,631. Supply systems for discharge lamps. FLUOTECHNIC, J. KEMENY, and B. COSNUAU. Feb. 1, 1961 [Feb. 2, 1960], No. 3831/61. Class 38 (4). A supply system for a pair of fluorescent lamps 3, 7, or two groups of parallel connected lamps, in which their filaments are interconnected in a series circuit from mains supply terminals 1, 15, includes three impedances 5, 9, 12 and an ignition device which permits heating current to flow through the middle impedance to effect filamentary electron emission during the starting phase, and reduces or interrupts the current after the lamps have ignited. The ignition device associated with the impedance 9 in the " bridge " connected circuit of Fig. 1 may be a glow, electro-mechanical, or electrothermal starter or a non-linear resistor of the voltage or temperature dependent type which, after the lamps have ignited, reduces the bridge current through the impedance 9 by at least a power of 10 or interrupts it entirely. So that equal lamp currents flow during the operating sequence, impedances 5 and 12 have preferably equal but opposite reactances. In Fig. 5, transformers 17, 18, forming the circuit impedances are arranged so that their secondary windings 17b, 18b, joined by a non-linear voltage dependent resistor 9, oppose each other during the starting phase. A large pre-heating filament current flows due to transformer windings 17a, 18a resonating with the capacitor 12b. After ignition, the lamp currents distort the voltage across the lamps so that their resultant phase difference, injected into the bridge arm formed by windings 17b, 18b, acts in opposition to reduce the bridge current. The resultant drop in volts across the resistor 9 causes a rise in its resistance, so reducing the bridge current still further. An additional choke may be connected between the mains terminal 15 and the lamp connection 14.
