Title: Improvements relating to ratchet type lifting jacks and toothed lifting pillars therefor
IPC: B66F1/00
Filed: 1950-03-15
Abstract: 672,060. Lifting-jacks. MATTHEWS, E. F. (Auto Specialties Manufacturing Co.). March 15, 1950. No. 6532/50. Class 78 (iii). A toothed lifting pillar for a ratchet-type lifting-jack is of a substantially V-shape in cross-section and the teeth are disposed in the vertex between the two side walls, the upper and lower faces of the teeth being disposed at different angles with respect to the plane of the recesses between the teeth. The toothed lifting pillar 24 consists of teeth 30 formed in the vertex between the walls 32, 34 of the pillar, which are preferably at an angle of 72 degrees. The top sides 40 of the teeth are more steeply inclined than the bottom sides 42 with respect to the recesses 36. The pillar is mounted in a base 48 by means of a supporting member 50 which has a recess in which the lower end of the pillar is received and held in place by a spring clip 52. The load-engaging crutch 26 is formed from sheet metal bent around the bar, Fig. 10, and having extensions bent horizontally and overlapping to form the support for a vehicle bumper. The pawl mechanism consists of pawls 74, 76 pivoted at 78, 80 respectively to a bracket 72 in which an operating lever 28 is mounted. Bracket 72 is pivoted at 70 to the crutch 26. The pawls 74, 76 are connected together by a spring 86 which normally holds the pawls in the relative positions shown in Fig. 9. A lever 98 pivoted at 100 on the crutch is provided with an abutment 102, which by turning the lever is engageable with the spring 86. In the disengaged position shown, Fig. 9, pawl 76 rests against a stop 104. Upon downward movement of the operating lever 28, pawl 76 is forced against a tooth on the pillar which causes pawl 74 to disengage. Upward movement of lever 28 causes pawl 74 to descend one tooth. The crutch therefore climbs down the pillar. When lever 98 is turned to bring the abutment 102 against the spring 86 both pawls are pressed against the rack bar so movement of lever 28 jacks the crutch up the pillar.

Title: Improvements in train line conductor systems for electric traction vehicles
IPC: B61G5/10
Filed: 1924-03-15
Abstract: 235,624. Ferguson, A. D., and Metropolitan-Vickers Electrical Co., Ltd. March 15, 1924. Supplying consuming devices.-To prevent a train-line conductor, carrying current for heating, lighting or other subsidiary purposes, from conveying propulsion currents means are provided for automatically de-energizing the trainline conductor if a through connection is made thereby between two motor coaches of a train. The heads of the jumper connectors and the covers of the jumper receptacles in the train-line interlock with switches in the jumper receptacles which control electromagnetic switches supplying current to the train-line and are so arranged that the latter are de-energized directly the last jumper is applied to make the through connection. A control train-line 9 is provided to co-operate with the heater-line 1 which is connected to a source of current by contactor switches 7 in the motor coaches. Switches 11 in the heater-line jumper receptacles control the energization of switches 7 in conjunction with the control line and auxiliary positive and the negative train-lines shown. From the circuit illustrated in Fig. 1 it will be seen that insertion of a jumper connector 2 between the open ends of the divided train-line 1 and the consequent throwing of the switches 11 interlocked therewith, which connect the control line through the jumper 10, will also disconnect the negative connections of the two sections of control line 9 and so de-energize the contactor switches 7. Figs. 2 and 3 show a switch construction which is mounted on a longitudinal axis in an extension of the jumper receptacles, Fig. 5. Two segments 13, 14 are fixed upon an insulated drum which carries a forked lever 19 and is biassed by a spring 18. The segments co-operate with three control fingers 24 fixed in the receptacle extension. The heel 31 of the forked lever rests normally upon a cam 30 upon a transverse spring-controlled spindle 28 which carries the cover of the receptacle. When this cover is lifted the switch is rotated by the cam 30 to open the circuit of the control line 9 as explained above, and the fork in the lever 19 is then aligned with a recess 32 in the mouth of the receptacle which admits a lateral projection on the jumper head. When the latter has been fully inserted it is rotated so as to actuate the lever 19 against the bias spring and cause the switch to close the connection between control line 9 and jumper. The jumper head is retained in this position when the receptacle cover is lowered to engage a projection on the exterior of the jumper head. Before a jumper can be removed the switch will be actuated automatically and held by the lifted cover in a position to de-energize the heater line 1, or, if the bias spring 18 be broken, the switch will open the control circuit as the jumper is turned in its receptacle prior to removal.

Class 7(2) A suction operated valve admits extra' air to the induction system at all times during the running of the engine except when the the 'throttle 'is opened quickly and the engine is under load, thus substantially reducing the degree of vacuum in the induction system on such occasions, and until the degree of vacuum is increased, and an adjustable needle valve is provided in the casing to control the flow of secondary air to the induction system. As shown the device is fitted to the induction pipe 17 and comprises a piston valve 2 and associate needle valve 5. When the engine is running slowly and the throttle valve is suddenly opened the drop in suction causes valve 2 to close the air inlets 12. A seat 11 is provided for the needle valve 5. A pin may be provided across the mouth of the extension piece 16. The pin is preferably wedge shaped in cross-section. A perforated tube may be provided which extends into the manifold from the piece 16. In a modifixation a pair of branch pipes lead from the casing 1 to opposite ends of the manifold of a four cylinder engine. The device is mounted so that gravity acts to pull the valve 2 away from the base 11, it being possible to omit the valve return spring 10. It is stated that more than one device as previously described, can be fitted to a large engine.

IPC: C10G73/06
Filed: 1967-02-13
Abstract: 1,155,695. Chlorinated hydrocarbons, recovery from mineral oil dewaxing process. EDELEANU G.m.b.H. 13 Feb., 1967 [12 Feb., 1966], No. 6870/67. Heading B1B. Dichloroethane, methylene chloride or similar chlorinated hydrocarbon solvents are recovered from dewaxed mineral or tar (filtrate) and from slack wax by steam-stripping the filtrate in two stages 2 and 17, passing the vapours from the first stage 2 into a condenser 4 maintained at a tem perature to produce a condensate comprising anhydrous solvent, passing the residual vapours to condenser 12 followed by separator 14 to obtain a water-layer and a solvent layer. At the .same time, the slack wax is steamstripped in two stages 9 and 19, the vapours from stage 9 are passed into the lower part of rectifying column 10, the upper part of which is supplied with solvent reflux from separator 14, and the vapour from the head of column 10 is passed into condenser 12 (or alternatively condenser 4). The vapours from steam-stripping stages 17 and 19 are passed to condenser 22, the condensate separates into solvent and undissolved water in separator 23, and the solvent is supplied to column 10 as additional reflux. Anhydrous solvent is collected in receiver 6. Anhydrous solvent, containing traces of wax is withdrawn from the lower section of column 10 through conduit 26. Dewaxed oil and paraffin wax are withdrawn from the system through conduits 28 and 29, respectively. If the dewaxing solvent is a mixture of dichlorethane and methylene chloride, the solvent condensed in condenser 4 consists predominantly of methylene chloride; and the solvent condensed in condenser 22 consists predominantly of dichlorethane. Condensers 4 and 12 may be operated under a pressure of 1.5 atmospheres absolute.

Title: Improvements in or relating to method of and apparatus for extracting aromatic products
IPC: C11B9/02
Filed: 1956-03-05
Abstract: <PICT:0796712/III/1> <PICT:0796712/III/2> A method of extracting essential oils, from vegetable materials with the aid of a liquid medium comprises placing the vegetable materials, such as flowers, seeds, beans or roots, if desired in a divided state, in a container adapted to be immersed in or to contain the liquid medium, subjecting the liquid medium to the action of one or more sources of supersonic waves and discharging the spent vegetable materials from said liquid medium.  The container 11 may be a basket made of wire gauze and so adapted as to occupy two well-defined positions in which it is either immersed in the liquid medium or in such a position separate from the liquid as to facilitate the removal of the spent vegetable matrials. The liquid medium, which may be a solvent or any suitable liquid extraction medium, may be contained in a tank or vat 1 and this vat is usually charged with the extracting liquid prior to the container receiving its charge of vegetable material. The vegetable material is fed into the container through the hopper 15.  The spent vegetable material is discharged by inverting the container as shown in the position 111 over a trolley 22 which fits under a fluid-tight mounting 19 of the enclosing case 14.  The sources of supersonic waves 7, may be immersed in the liquid medium or attached to the side of the tank or vat so that when in the latter position they coincide with ports 13 in the container.  An alternative to the above apparatus dispenses with the basket container and the vegetable material is placed directly in the vat with the liquid medium.  The liquid is then removed, after extraction has been carried out, through pipe 3.  The example discloses the extraction of Jasmine flowers using petroleum ether as the liquid medium.  Devices to adjust and control such conditions as temperature and pressure may be mounted on the tank 1.

Abstract: 771,940. Supply systems for space-discharge tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 9, 1955 [March 12, 1954; Sept. 18, 1954], No. 6930/55. Class 38 (4). In a circuit comprising a gas and/or vapourfilled electric discharge tube 1, e.g. a fluorescent lamp, having two filament electrodes, 8, 9 and a combined filament heating and arc discharge current supply transformer 2, one, 9, of the electrodes is connected in series with a first winding 12 of a separate auxiliary transformer 11 and the two in series are connected across a secondary winding 3-13 of the transformer 2, and the other electrode, 8, is connected across a second winding 10 of the auxiliary transformer 11; said auxiliary transformer has no more than the two windings which within the transformer are electrically insulated from each other, and has the property of low impedance when on load, but high impedance when on no load, whereby should one filament heating circuit be interrupted the impedance of the winding in the other circuit becomes so high that the electrode therein is not brought to an electron-emissive temperature, thereby preventing initiation of the lamp when one electrode is unheated. As shown, the transformer 2 is autowound, comprising a primary winding 3-5, an arc discharge supplying secondary winding 3-4 and two filament heating secondary windings 3-13 and 14-4, all determined by tapping points on a single coil, and the latter winding supplying electrode 8; in another embodiment, Fig. 1, not shown, the electrode 8 is connected across only the winding 10. The lamp may have on the inner or outer side of its envelope an electricallyconductive coating, not shown, to facilitate ignition. Suitable valves and constructions of circuit components are described in the Specification. Specification 772,525 is referred to.

[Class 108 (iii).] In resilient supports in which a helical spring is arranged in series with a rubber buffer, a member in the form of a piston working in a cylinder or equivalent compresses a rubber block in the cylinder, the arrangement being such as to avoid metallic contact. The apparatus is intended to support loads from conveyers and similar apparatus. Two helical springs 5 connect bolts 3, 6, a pair of flexible check wires 20 being also provided. A rod 8 extending downwards from the pin 6 carries a piston-like member 9 which slides with clearance in a cylinder 10 and compresses a rubber block 13. The supporting rod 15 extends downward from the lower end of the cylinder 10. Rotation of the several parts is prevented by projections 14 on the piston 10 and the upper abutment 11 engaging recesses in the rubber block. The return movement of the piston is cushioned by a rubber pad 19. In a modification the tension springs are replaced by a helical spring surrounding the rod 8. In a further modification forming a resilient compression element or buffer a helical compression spring is arranged inside the cylinder containing the rubber block.

Title: Optoelectronic photocoupling device
IPC: H03H11/02
Filed: 1975-02-19
Abstract: 1503735 Opto-electronic coupling devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 Feb 1975 [22 Feb 19741 6989/75 Heading G1A An opto-electronic coupling device comprises a semi-conductor light emitter and a semi-conductor light detector aligned adjacent one another on a common optical axis, connected to respective electrical conductors, and optically coupled by a light conductor constituted by a first transparent resin in direct contact with the emitter and the detector and immediately surrounded by a second transparent resin having a lower refractive index than the first. In a method of making such a device, during a viscous polymerization phase the first resin is given a suitable optical shape, and after polymerization is complete the first resin, the emitter and the detector are covered by the second resin. A Ga-As LED 1 is mounted on an electrical conductor 3a constituting a support and a terminal, a further terminal connection being provided by a wire 4 and a conductor 3b. A Si photodiode 2 is similarly provided with support and connections by conductors 5a, 5b and a wire 6. An intervening space is bridged by a drop of transparent epoxide first resin with amine catalyzer 7 having a refractive index higher than 1À55, preferably 1À6. While the first resin 7 is still in the viscous phase the spacing between the emitter 1 and detector 2 is adjusted to give maximum light transfer efficiency, which results when the resin 7 assumes roughly the shape of two paraboloids bridged by a spherical zone, the emitter and detector being at the foci of the respective paraboloids. After the first resin 7 has been fully cured e.g. for 2 hours at 150C, the emitter 1, detector 2 and the first resin 7, together with portions of the conductors 3a, 3b, 5a, 5b, are embedded in a second transparent resin 8 comprising a silicone elastomer having a refractive index lower than 1À45, preferably 1À4, and cured for an hour at 100C. The device may be protected mechanically and optically by a casing 9 of metal or of opaque filled resin. Quantity production may be assisted by preparing comb-like strips, of which the conductors 3a, 3b, 5a, 5b constitute the teeth.
