Title: Improvements in golf balls
IPC: A63B37/00
Filed: 1956-11-09
Abstract: <PICT:0798980/III/1> Golf balls are treated with high-voltage electrons, whereby the outer cover is toughened, but the inner core winding is uninjured. A Van der Graaf or similar electron accelerator generating preferably 200 to 800 kilovolts is used, but higher voltages may be applied with a paper shield.  Details are given of voltage, dosage and other conditions required to prevent penetration and absorption of electrons beyond the outer cover.  For example, a polyethylene cover 0.05 inch thick will absorb 90 per cent of the energy generated at 300 kilovolts.  Preferably the golf balls are cooled to prevent the temperature exceeding 100 DEG  F.  The outer cover may consist of balata or polyethylene, and may also contain polystyrene butadiene and natural rubber.  Low molecular weight polyethylene may be used.  In the case of balata, the process cures the material and replaces vulcanizing.  Golf balls thus treated are resistant to cutting and scuffing.  A beam of high-voltage electrons passes through an aluminium window 3, Fig. 1, of a housing 2 which may be provided with a cooling coil.  A series of golf balls 4 roll back and forth along a channel 5 and are exposed to the radiation. The electron beam may, by a magnetic field or other means, be made to traverse their path. Alternatively, the balls may be rotated on a mounting disposed in the beam.

Filed: 1968-07-18
Abstract: 1,183,458. Radio navigation. STANDARD TELEPHONES & CABLES Ltd. 18 July, 1968, No. 34323/68. Heading H4D. Distance between two stations is measured by emitting respective frequencies f, f + #f from spaced points at one station, receiving both emissions at points similarly spaced at the second station and comparing at the latter the phases of the two ensuing signals of beat frequency #f The transmitting station may utilize varactor up-converters to form f = 12GHz and f + #f = 12À0001 MHz; the transmitters operate for 0À01 seconds at one second intervals. The phase meter may comprise limiting and differentiating stages to produce pulses at 8f which on one channel set a bi-stable circuit and on the other channel re-set it. Velocity of the receiving station relative to the transmitting station is given by measuring the shift of frequency f to afford the time to closest approach. In an aircraft anti-collision system each aircraft carries a pair of spaced aerials cyclically switched from transmission to reception; difference frequency #f may be coded for barometric height, receivers being arranged to respond only to transmissions from aircraft at a similar height. A ground beacon may be provided with the transmitting arrangement; glide-path information may be added by including a reference signal at frequency #f as a frequency modulation of a sub-carrier which amplitude modulates the radiation on frequency f: in the receiver a preselected glide slope is defined by a constant phase between the reference signal and the beat frequency #f. If the reference wave were transmitted from the airborne apparatus, measurement of relative angles of elevation between craft becomes possible.

Title: Improvements in or relating to sand moulds and cores for casting metals
IPC: B22C1/16
Filed: 1954-11-26
Abstract: A binder composition, for use in making sand moulds or cores for casting metals, contains particles of a water-soluble cellulose ether and particles of a natural and/or a thermosetting synthetic resin, together with Portland cement or plaster of Paris and water.  The preferred proportions by weight are 100 parts of sand (dry bases), 2 to 25 parts (particularly 6 to 12 parts) of cement, 0.2 to 2.0 parts (particularly 0.4 to 0.8 parts) of cellulose ether and resin and 3-7 parts of water, including any water present as moisture in the sand. The relative proportions of cellulose ether and resin may be 20 to 90 (preferably 70) per cent by weight of cellulose ether and 80 to 10 (preferably 30) of resin.  The cellulose ether may be methyl, ethyl, methyl ethyl, hydroxyethyl, or methyl ethyl hydroxyethyl cellulose, a water-soluble salt of a cellulose ether carboxylic acid, cyanoethyl cellulose or sulphoethyl cellulose.  Natural resins used may include rosin, tall oil rosin, esterified rosin, or a saponified rosin such as potassium, calcium, ammonium or hydroxyalkylamine resinate. Synthetic resins used may include urea-formaldehyde or phenol-formaldehyde resins, melamine resins, polyvinyl resins, sulphamide resins and acrylate resins. Cement hardening accelerators such as calcium chloride, sodium silicate or sodium carbonate may be added to the composition, e.g. in a proportion of 0.2-4 per cent based on the weight of the sand.  In an example, 100 litres of fresh sand containing 2 per cent by weight of moisture are mixed with 8 kgs. of cement followed by 1 kg. of a mixture of 70 per cent by weight of ethyl hydroxyethyl cellulose and 30 per cent by weight of a melamine resin, and finally with 2.5 litres of water.  In the second example half the fresh sand is replaced by mould sand. Specifications 696,965 and 754,823 are referred to.

Title: Infinitely variable hydraulic gear unit
IPC: F16H39/36
Filed: 1953-12-15
Abstract: 756,073. Hydraulic couplings; fluid-pressure servomotor control systems. KLATTE, T., [trading as KLATTE, T., [Firm of]]. Dec. 15, 1953 [Dec. 17, 1952], No. 34937/53. Classes 69 (2) and 135. A hydraulic infinitely variable speed gear comprises a pump and motor of the internal gear type. An input shaft 1 carries the inner wheel 2 of the pump, the external wheel 14 being rotatably mounted in bearing rings 5, 6 fast with an output shaft 7. The output shaft 7 carries the inner wheel 32 of the motor, the outer wheel 33 being rotatably mounted in bearing rings 37, 38 fast with a housing 11. Oil passes through a hollow shaft and slots in the inner wheel of both the pump and the motor, to and from the spaces between the gear teeth, and the oil flow is controlled by rotary distributer valves 21, 47. Valves 21, 47 are stationary relatively to the output shaft 7 and the housing 11, respectively, except when they are rotated for adjustment purposes. This is effected by a centrifugal governor 52 driven from shaft 1 and controlling the position of a piston 60 which, through suitable linkages, controls the position of the valves. Starting.-With the prime mover idling, piston 60 is in its upper end position and valve 21 is thereby set to give zero output and to allow the oil to circulate idly in the pump. The valve 47 is set for maximum flow. As the speed of the shaft 1 increases, piston 60 descends under the control of the governor, and the pump output is increased consequentially, the effective stroke space of the motor being simultaneously decreased. At a speed determined by the governor, valve 21 reaches the position giving maximum output from the pump, and valve 47 reaches the position in which it cuts off the supply to the motor and allows the oil to circulate idly in the motor. The internal and external wheels of the pump and the bearing rings 5, 6 therefore rotate solid, and a direct drive is obtained. To obviate any power losses the pump output may be cut off by a valve 85 sliding in the valve 21, and the motor may be emptied. Braking.-The prime mover is set for idling, then, by means of a lever 91 and an associated linkage, the valve 47 is turned beyond its zero external flow position and the motor acts as a pump, the oil discharging through a safety valve 101 when the maximum pressure is exceeded. Reverse running.-The prime mover is adjusted for idle running and lever 91 is moved into an end position in .which the valve 47 is turned through 180 degrees from its starting position. On opening the throttle of the prime mover, the pump therefore drives the oil motor in reverse.

Title: Improvements in or relating to tyre scrapers
IPC: B60S1/68
Filed: 1920-12-11
Abstract: 176,871. Mahler, E. Dec. 11, 1920. Wheel scrapers on vehicles.-Relates to tyrescraping or puncture-preventing devices comprising a stiff stirrup-shaped member the bar of which straddles the tyre while the limbs are pivoted to the vehicle on a transverse axis situated at the rear of the bar. According to the invention, the distance between the pivotal axis of the scraper and the centre of the wheel is less than the radius of the tread of the tyre so that contact with a nail &c. tends to press the scraper against the tyre. As shown in Fig. 1, the scraper comprises an arched member 1 formed with limbs 2 which are pivoted at 3 to members 4 on clips 5 secured to the front fork of a bicycle. A second scraper 8 may have its limbs linked to loops 9 on the first scraper. In a modification, the limbs of the - second scraper may be looped around the limbs of the first to form a sliding pivotal connection. In the further modification shown in Fig. 3, the limbs of the second scraper are bent up at 10 to form stops which prevent this scraper from being thrown out of action. The limbs of the first scraper may be similarly bent. The device may be mounted on any convenient part of a vehicle, for example it may be pivoted to a curved bar secured transversely on a mud-guard. According to the Provisional Specification the scraper, when used with studded tyres, may be provided with antifriction rollers &c. which bear on the tyre and hold the scraper clear of the studs.

Title: Alternator control circuit
IPC: H02P9/30
Filed: 1972-07-26
Abstract: 1346284 Alternators MOTOROLA Inc 26 July 1972 [5 Aug 1971] 35021/72 Heading H2A [Also in Division G3] In an alternator control system, current to energize the alternator field winding is derived from the reverse voltage pulses which are generated in the alternator output windings as a consequence of the rapid cut-off of current in the output diodes. In the arrangement shown, a voltage regulator 40 closes a switch 42 whenever the PD between a pair of output terminals 18, 20 is below a pre-set level, and the reverse voltage pulses generated in two of the alternator output windings 12b, 12c as a result of current cut-off in corresponding output diodes 16b, 16c are then able to energize the primary winding 32a of a rotary transformer 32; the transformer secondary winding 32b, which is mounted on the same rotary shaft as the alternator field winding 14, thereupon activates winding 14 via, a bridge circuit 34. The regulator/switching system 40/42, by means of which feedback from the output is effected, may include a triac/thyristor arrangement as described with reference to Fig. 2 (not shown), or a silicon controlled rectifier (82) as described with reference to a further embodiment (Fig. 4, not shown).
Patent GB-850885-A (GB)
Title: Improvements in or relating to polyfluoroethylene films and methods of making them
IPC: C08J5/18
Filed: 1958-10-31
Abstract: Polyfluoroethylene films are made by coating an aluminium casting surface with a liquid suspension of particles of at least one polyfluoroethylene, evaporating the liquid, sintering the particles into a film, heating the film-coated surface for a period and at a temperature such as to reduce the adhesion of the film to the surface sufficiently to render the film detachable in a coherent state, and thereupon peeling the film from the surface. In an example a length of soft-temper aluminium foil of 0,2 mil. thickness is dip-coated to a thickness of 1/4 mil. at room temperature with a 42% by weight aqueous dispersion of polytetrafluoroethylene particles having an average diameter of about 0,3 micron, the dispersing medium containing a non-ionic alkyl aryl alcohol wetting agent. in the proportion of about 6%, by weight based on the polymers.  The dip-coated foil is then baked dry, and the residual coating is fused at 450 DEG F. for ten minutes and cooled to room temperature.  The fused film adheres tightly to the foil and cannot be stripped from it without damage. A length of the foil is then wound on to a reel in an open or loose manner so that adjacent turns of the coil are not forced into close contact with one another, and baked in air for 90 hours at 250 DEG C., whereafter the film can be peeled from the foil without damage.  A second length of foil is immersed in boiling water for 15 minutes and then dried, and a third length of foil is exposed for 5 minutes to low-pressure steam.  In both cases the films can be peeled from the foil in the dry state.  Self-supporting polytrifluoromonochloroethylene films may be similarly produced.
