Title: Improvements in metal-fabricating oils
IPC: C10M141/10
Filed: 1938-08-19
Abstract: 510,926. Metal-working oils. STANDARD OIL DEVELOPMENT CO. Aug. 19, 1938, No. 24412. Convention date, Nov. 12, 1937. [Class 91] A clean and transparent composition for use as a cutting oil or stamping lubricant consists of a predominating proportion of a mildly sulphurized mineral lubricating oil containing a small proportion of sulphur in a soluble, corrosive form and an ester of an acid of phosphorus. An amount of sulphur of 0.5 to 2 per cent. may be added to the oil. The sulphur may be in the form of a corrosive compound formed by the direct action of a sulphurizing agent on the oil under mild conditions. The ester may be tricresyl phosphite or phosphate. In an example, a straight mineral distillate of viscosity 100 secs. Saybolt at 100‹F. is heated with 2 per cent. of sulphur at 300‹F. for 0.5 to 1 hour till the sulphur is dissolved. The oil is cooled and 2 per cent. of tricresyl phosphate added. The product sustained 15 units of weight then tested on the Ahnen machine as compared with 3 to 4 units for the untreated oil.

Title: Supply of an excitation winding of a polyphase alternator
IPC: B60L50/12
Filed: 1971-04-19
Abstract: 1350963 Protective arrangements SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM) 19 April 1971 [17 March 1970] 24472/71 Heading H2H [Also in Division G3] A supply system for a self-propelled vehicle comprises a heat engine 2 driving an alternator 1 which supplies D.C. drive motors 3 of the vehicle through a rectifier 4 and which supplies its field winding 5 through a rectifier formed by three diodes of the rectifier 4 and three thyristors 6 whose firing angles are controlled to maintain the alternator output voltage at a predetermined value. A divider 11, 12 provides a signal representative of the voltage of the rectifier 4 to a comparator 13 which is also supplied with a reference voltage 14 representative of the predetermined value and which produces an error signal for transmission to an amplifier 15 whose gain is controlled by the signal from divider 11, 12. The output of amplifier 15 is supplied to a gate control device 17, which also receives phase reference signals A1, A2, A3 from the anodes of the thyristors 6 and the signal from an electronic switch 19 which performs the triple function of selecting the appropriate phase reference signal, controlling the filtering of the latter signal and varying the gain of the device 17 in accordance with the output of the amplifier 15. The outputs of the device 17 control a trigger circuit 20 providing firing signals to the thyristors 6. A circuit comprising elements 21-26 limits the voltage developed across the field winding 5 in a manner described later. This circuit may be replaced by an inductor-capacitor combination, Fig. 1 (not shown). Protective action of the circuit 21-26.-The voltage developed across the winding 5 is coupled via the capacitor 25 and damping resistor 24 to the primary winding of the transformer 21, whose secondary winding is limited to a voltage determined by the battery 22. Thus when the voltage across winding 5 exceeds a predetermined value corresponding to the latter limit, the diode 23 conducts to cause the excess voltage to charge the battery 22.

Patent GB-244750-A (GB)
Abstract: 244,750. British Thomson-Houston Co., Ltd., (Assignees of Hall, C. I.). Dec. 16, 1924, [Convention date]. Cut-out arrangements for dealing with moderate overloads of relatively long duration employ thermal devices each operating a plurality of independently movable circuit-controlling members having a plurality of circuit controlling positions with " off " positions between for selectively operating load regulating devices in response to predetermined overloads. For protecting a generator 10 a thermal device 18 is provided which has thermal characteristics substantially duplicating those of the generator. The device 18 comprises a heating resistance 27 connected across a shunt 28 in the load circuit, a heat-storage mass 20 and a bimetallic strip 19. The strip 19 has attached to its free end an operating bar 29 which actuates fixed contact bars 21, 22 moving between adjustable contacts 23 - - 26. These contact bars control the energization of the coils of electromagr.etic snap-action switches 35, 36 which in turn control contactors 15, 17 the former normally shortcircuiting a resistance 14 in the line 13 and the latter a resistance 17 in the field circuit of the exciter 12. The arrangement of contacts in the thermal device and electromagnetic switches is such that no circuit is broken by the bars 21, 22 and the switches 35, 36 are provided with dead-centre springs to enable them to break their own operating circuits. When one predetermined overload occurs the strip 19 is heated sufficiently to bring the bar 21 to engage the contact 24 so completing the circuit of coil 37. The contact bar of switch 35 is then moved to engage its right-hand contacts so energizing the contactor 15 and placing the current-limiting resistor 14 in the load circuit. On a predetermined greater overload the bar is further flexed to cause the engagement of contact bar 22 and contact 25 with consequent energization of the coil 39 of switch 36 and operation of the contactor 17 to reduce the voltage of the generator. To prevent the contact bar 21 from damage during this subsequent bending movement of the bar 19 the member 29 engages a coaxial pivoted lever 30 connected by a spring 32 to the operating arm of the bar 21. Similarly in the downward movement of the bar member 21 rotates a lever 31 connected by a spring 33 to the lever 30, a spring 34 pulling down the operating arm of the bar 22, so that during the cooling of the strip corresponding to a drop in load circuit operations of the thermal device and its associated switches and contactors occur in reverse order before the circuit is restored to the normal condition as shown. The adjustment of the relatively fixed contacts 23 - - 26 determines the load values at which automatic switching operations occur.

Title: Improvements in or relating to the manufacture of artificial marble
IPC: C04B28/32
Filed: 1934-08-27
Abstract: Artificial marble is made by kneading a dry mixture comprising magnesia, marble powder, and calcium sulphate (as crude gypsum or crude alabaster) into a paste with a solution of magnesium chloride, adding to this paste magnesium oleate and magnesium stearate emulsified with tallow soap, and causing the resulting mixture to set to the desired shape with or without armouring.  If armouring is used the mixture sets in permanent union therewith. Colouring matter may be added to the dry mixture.  In an example 100 parts of magnesium oxide, 30 of finely ground marble dust and 20 of calcium sulphate are mixed dry, then kneaded with magnesium chloride solution, then 1 part of emulsion is added.  This is spread on a vaseline- or oil-smeared mould of glass, crystal, metal, &c.  Variegated colour may be obtained by the use of differently coloured pastes.  The armouring may be of artificial slate or wood, natural slate or wood, sheet metal, or cement conglomerates.

Filed: 1935-09-05
Abstract: 462,532. Electric cables. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 5, 1935, Nos. 24793 and 24794. Convention dates,'Sept. 5, 1934 and Oct. 25, 1934. [Class 36] A television cable comprises a quad, Fig. 1, the conductors 1 of which are rigidly held in spaced relationship by insulating discs 2, e.g. of ceramic material having a low angle of loss and a low dielectric constant. The discs 2 are slotted as at 3 to house the conductors which are maintained in position by wedges, insertion pieces 5, Fig. 2, or in any suitable manner. When as in Fig. 1, the quad is twisted the conductors are maintained in position by the tension therein further securing means being dispensed with. The quad is covered by a screening lead sheath 4, beneath which a layer 6 of brass, copper, aluminium or of insulation, e.g. paper is provided to prevent any lead powder or shavings that may be formed, from contacting with the conductors. In such a cable the phantom circuit only is suitable for television transmissions, the side circuits being used only in the lower frequency range, but by providing a copper or brass layer 6, Fig. 5, insulated at 7 from the lead sheath 4, the side circuits may also be used for television transmissions. The metallic layer 6 is subdivided to prevent the flow of eddy currents while still providing adequate screening. Reference has been directed by the Comptroller to Specifications 5227/01, 18180/01, 19510/01, and 11487/02, [all in Class 36].

Title: Elevator System
Inventor: BRUNS WILLIAM HENRY
IPC: G01G19/18
Filed: 1967-05-30
Abstract: 1,172,258. Measuring weight electrically. OTIS ELEVATOR CO. May 30, 1967, No.24956/67. Heading G1N. [Also in Division G4] The load carried by a lift car is measured by the change in permeability of a magnetostrictive nickel rod subjected to the load. The lift car 29 Fig. 1 and a counterweight 31 are supported by cables 27, 28 passing over sheaves 24, 25 attached to a horizontal bedplate 21 with limited rotation about a central fulcrum 32. The basic parts of the lift system are mechanically balanced so that the rotational moment is due to the load in the lift car only. One end of the bed plate 21 is rigidly attached to the bottom of a magnetostrictive nickel rod 121 Fig. 3, which is itself clamped between a plate 117 and a fixed beam 71. The rod forms part of the magnetic circuit of a transformer 125 whose output is therefore reduced when the permeability of the rod 121 is reduced by stress caused by the movement of the load about the fulcrum 32. A similar but unstressed transformer 136 is mounted above the plate 117. The two secondary windings are connected in series opposition giving a resultant output signal indicative of the lift load. This signal is rectified and fed to a relay circuit which gives indications at different values of load. A further relay, which is only energized when the car is moving, causes the measuring relays to hold their readings during movement, and permits further measurement when the lift car stops at a landing.

Abstract: 821,453. Yarns; woven fabrics. MILLER, G. D. Aug. 16, 1956 [Sept. 8, 1955], No. 25066/56. Drawings to Specification. Classes 120(3) and 142(4) [Also in Group VIII] A plied yarn, having a high capillary lift effect for wicking liquid lubricant, comprises a plurality of single yarns, each having a twist per inch of 2.25#N, twisted together with a reverse twist per inch of 1.80 #/P; where N and P are yarn numbers of the singles and plied yarns respectively in the woollen American cut system. In an example, a single yarn of 17 count (American cut woollen system), and a twist of 91/3 turns per inch is spun preferably on the woollen system from a mixture of 85% 3-denier Vicare (man-made protein) fibre and 15% 64's quality wool fibre. Two such single yarns are plied together with a twist in the opposite direction of 5“ turns per inch. The plied yarns are woven into a fabric with not more than 11 warps and 9 wefts per inch. An antistatic agent is applied to the Vicara fibres before spinning and removed after weaving. The fabric is pre-shrunk and incorporated in a laminate consisting of alternate layers of fabric and carded wool or felt united or by felting. Cotton or rayon fibres may be used instead of Vicara. Specifications 715,026 and 746,103 [both in Group XXXIV], are referred to.

Title: Improvements in parking meters
IPC: G07F17/24
Filed: 1956-08-16
Abstract: 804,727. Parking meters. MENHALL, J. W. Aug. 16, 1956 [Sept. 2, 1955], No. 25077/56. Class 27 A parking meter can be set to different periods by several coins of the same or different denominations and comprises a rectangular tubular coin carrier 60 pivoted on a cup-shaped member 43 rotated by a handle 38 and the carrier is pivoted by different amounts in response to coins of different sizes so that, on rotation of the member 43, it picks up teeth 27 on a winding disc 26 at different points and correspondingly winds up a timing unit 20 and sets a pointer 10. Also pivoted to the member 43 is an operating lever 45 having an arm 51 engageable with a ramp 52 and a pair of posts 56, 57 which are of different lengths and, on rotation of the member 43 in the absence of a coin, can pass through openings 43a and 66 in the member 43 and carrier 60. If a smaller coin is in position resting on a stop 70, the shorter post 57 bears against it as the first incline 53 of the ramp 52 rotates the operating lever 45 and, through the coin, pivots the carrier 60. The carrier is not, however, pivoted sufficiently to pick up the earlier teeth 27 and it is not until the arm 51 engages a second incline 58 that the carrier is pivoted fully so that a projection 73 engages a tooth 27A of the winding unit. Continued rotation of the handle will then wind the timing unit and set the pointer for a one-hour period. The pointer is spring-biased away from the zero position but an arm 31 in engagement with a stop 32 on the disc 23 prevents this movement until the stop 32 moves with the disc. If a further small coin is inserted, the tooth 27B is picked up so that another onehour increment is added to the period. If a larger coin of higher value is inserted in the coin carrier, the longer post 56 engages it and the first incline 53 pivots the carrier sufficiently for it to pick up the first tooth 27C and set up a longer period corresponding to the increased value of the coin. When the carrier has been rotated beyond the second incline 58, it is spring-returned to its initial position, the arm 51 passing under the ramp 52. A part 68 of the carrier turns over a pawl 76 so that it co-operates with ratchet teeth 75 on the member 43 to compel full rotation of the handle 38. The pointer shaft 24 is connected by a gear 30 and rack sector 89 to a lever 90 having a roller 91 bearing on a cam surface 92 on the member 43 and, on initial rotation of the handle, the pointer is returned to zero and maintained in this position until the handle is returned to its normal position. Exhibiting coins. After the arm has passed the second incline 58, the coin falls from the carrier 60 and is supported in front of a window 81 by a lever 82 until, on the next rotation of the carrier, the part 68 engages the end 84 of the lever and pivots it so that the coin is released and the succeeding coin can fall on to the lever 82.
