Title: An arrangement for controlling an operation depending upon whether a device is in motion or stationary
IPC: B60T13/66
Filed: 1928-01-02
Abstract: 285,804. Associated Telephone & Telegraph Co., (Assignees of Hudd, A. E.). Feb. 21, 1927, [Convention date]. Fluid-pressure.-Apparatus for controlling an operation depending upon whether a device is stationary or in motion in which the operation takes place or not according to the relative position of two members comprises one member adapted to move only in a normal direction towards the surface of the device and provided with a second member interposed between the first member and the surface and incapable of being moved relatively to the first member solely by the pressure exerted thereon by the first member but if the surface is in motion the second member is moved relatively to the first member against a restoring force and is held in a position away from its normal position until the first member is withdrawn away from the surface. The apparatus illustrated forms part of an automatic train control system and is for the purpose of preventing the driver from releasing the brakes following an automatic brake application, before the train has stopped. A piston 4, 11 slidable in a fixed cylinder 10 mounted over one of the wheels W of the locomotive carries a member 5 having a spherical seating on the part 11 and held in the normal position shown in relation to the piston by a spring 8. The piston is held in the retracted position by a spring 18 abutting on the end 12 of the piston and that of a bolt 17 secured to the fixed collar 19. A pipe 2 is arranged to supply compressed air to the interior of the piston 4 by way of apertures 13. The pipe 2 also communicates with a piston 3 arranged to actuate contacts 7 of an electric switch, the operation of which permits of release of the brakes. Normally the pipe 2 is open to atmosphere by way of the orifice 28 in a valve device C. If the lever of this device is de. pressed a valve 29 is opened to admit pressure air to the pipe 2. As the spring 18 is weaker than the spring 6 of the piston 3, the piston 4 is first moved so as to bring the part 5 into contact with the wheel W which if the wheel is rotating is then deflected so that flutings 9 permit escape of the air from the piston 4 and pipe 2 so that the piston 3 is not actuated. If however on account of the wheel being stationary the member 5 is not so deflected, the pressure rises beneath the piston 3 sufficiently to overcome the spring 6 and the contacts 7 are operated. The device is also applicable to signalling systems in mines where for instance it is important to avoid the change of a signal while the elevator is moving.

Inventor: NIELSEN PER GAMBORG
IPC: A23K1/18
Filed: 1993-02-08
Abstract: A bait product for use, for example, when fishing for carnivorous fish is produced from a mixture which comprises starch, galactomannans or cellulose ethers, alginic acid, or salts of alginic acid or pectin or pectate, together with preservatives, aromatic substances and water. The mixture is hardened in an aqueous solution of a calcium salt. In the process for producing the bait product, the procedure involves several steps. In a first step, the ground animal constituents are mixed to form a relatively dry, homogeneous mixture. Preservatives, aromatic substances and water are mixed in the next step. In a third step, the aqueous mixture from the second step is added to the dry mixture from the first step while stirring continuously. Shaping in an extruder takes place in the fourth step. In a fifth step, the shaped product is immersed for a limited period in a bath which contains an aqueous solution of the calcium salt. The finished product is mouldable and nevertheless insoluble when used as bait. At the same time, it contains no, or very few, synthetic additives.

Abstract: 835,729. Tool-holders. SANDVIKENS JERNVERKS A.B. Jan. 7, 1958 [May 29, 1957], No. 624/58. Class 83 (3). A tool-holder comprises a chip-breaker 27 between a clamp 25 and the cutting-tip 22, and a resilient device 28 to press the breaker 27 against the clamp so that it remains in contact therewith when the clamp is released to remove or adjust the tip. The resilient device may be in the form of one or more leaf-springs mounted on the clamp or, as illustrated, a pin 28 pressed outwardly of a passage 30 in the tool-holder by a spring, a shoulder formed by a flat on the pin co-operating with the edge of a seating 23, e.g. of sintered " hard-metal," to prevent escape of the pin. The seating 23 for the tip 22 of square, triangular, circular, &c. form may be adjustable or, as illustrated, secured in the tip-recess by a screw. Ridges, or a lip 37 on the clamp, engages grooves 36 in the breaker 27, which is received in a channel 35 in the clamp, and a forward-lip 38 and rear abutment on the underside of the breaker may bear respectively, on the tip 22 and shank of the tool-holder. Pads at the rear corners of the clamp bear on the shank, and a projection at the forward edge locates in a slot 43 in the shank. A screw 26, preferably with a part-spherical head, secures the clamp to the shank and may be formed with screw-threads of both hands preferably to loosely-engage respectively, screw-threads in the clamp and shank. As illustrated in the modification of Fig. 11, in which a spring-pressed flanged pin 57 acts on the breaker, the part-spherical head of the screw permits the clamp to be tilted by the pin upon release of the clamping pressure. Pressure applied to the end of the breaker disengages the grooves therein from the lip on the clamp, and by means of a rod 45 inserted in a groove or bore in the clamp, the position of the breaker can be varied.

Title: A method and apparatus for cleaning chocolate moulds
IPC: A47L15/24
Filed: 1946-01-08
Abstract: 635,755. Cleaning chocolate moulds. STEENBERG, A. C. Jan. 8, 1946, No. 670. Convention date, July 22, 1939. [Class 87 (ii)] [Also in Groups XXIII and XXX] Chocolate moulds are cleaned of fatty and sticky matter by. subjecting the surfaces of the moulds to jets of dry or superheated steam, in a confined space, and simultaneously removing the steam by suction. The moulds are put into a steam chamber 12, in a casing 10, along guides on a bracket 34, and then they are carried vertically between conveyers 26, 28. Steam under pressure is projected through a series of nozzles fitted to pipes 56. The steam is removed downwardly, by an exhauster 80, from the chamber 12 through a gap 14 into a lower chamber 16. This arrangement prevents dirty steam contacting cleaned or partly cleaned moulds. The pressure in the chamber 12 is kept about atmospheric. The last nozzles of the series are situated near the point of removal of the moulds to prevent steam condensing on the moulds. The upper conveyer is vertically adjustable, through mechanism operated by a hand wheel 52 to accommodate various sizes of moulds. The nozzles are also vertically adjustable by an associated mechanism which provides that the nozzles are situated halfway between the conveyers. The nozzles are oscillated, to project the steam from the upper to the lower edges of the moulds, through mechanism connected to driving gear 22. This mechanism is so arranged that the amplitude of the oscillations is dependent on the distance between the conveyers. A sludge container 18 is provided. Specification 635,819, [Group XXX], is referred to. The Specification as open to inspection under Sect. 91 comprises also the application of the invention to articles other than chocolate moulds. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,126,741. Detecting impurities. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 21, 1965 [Jan. 7, 1965], No.756/65. Heading G1N. [Also in Division H1] In an apparatus measuring changes in resistivity of contaminated liquid metal flowing in a tube 31, Fig. 4, (as in Specification 936, 040), wherein a winding 39 on a core limb 32 passing between two branches of the tube induces a current in the liquid and the voltage induced in a winding 34 by this current is proportional to the resistivity of the liquid, this voltage is connected via a transformer 41 to a phase sensitive rectifier 45 where it is compared with the secondary voltage of a transformer 11, two primaries of which are respectively connected across a resistor 19 mounted on the tube 31 to be at the liquid temperature, and a stable (manganin) resistor 22. The resistor 19 is selected to have a temperature co-efficient of resistivity approximating to that of the liquid metal and is made of gold if the liquid is sodium, and a further platinum resistor 36 may be connected across a third primary winding. The stable resistor 22 is either a zero temperature coefficient resistor, or a resistor maintained at a constant temperature. The resistors 19, 22 and 36 are arranged to carry to same alternating current as is supplied to the core excitation winding 39, and the number of turns on each of the windings of transformer 11 is adjusted so that the secondary voltage is the same as would be produced if the A.C. were supplied to a single imaginary resistor having the same resistance and temperature co-efficient as the liquid metal in the pure, uncontaminated state. This secondary voltage is compared with the secondary voltage of a transformer 41 representing the resistivity of the contaminated metal, in the phase sensitive detector 45, the reference voltage for which is obtained from the A.C. source by means of a resistor 38. Two constructions of the summation transformer are given, each having only two primaries. Each primary consists of a pair of windings, the first pair 14, 15, Fig.1 (not shown) being mounted on the outer legs of a first three limbed core (9), and the second pair (12, 13) being mounted on the outer legs of a second similar core (8), the secondary (11) being wound around both the central limbs (16). Alternatively Fig. 3 (not shown) the cores are arranged end to end, the secondary being wound around the adjacent end limbs, and the primary windings being wound on the remaining limbs. Ganged switches are provided to adjust the ratios of the transformer, Fig. 2 (not shown), and a further set of switches (24) set the transformer for different ranges of resistance values (19, 22) to be measured.
