Title: Dynamic simulating device for eye testing
IPC: A61B5/18
Filed: 1962-10-18
Abstract: 982,874. Stereoscopic sight testing apparatus. C. G. PAYNE. Jan. 9,1964 [Oct. 18, 1962], No. 39545/62. Heading G2J. A stereoscopic sight testing apparatus comprises a base 1, small models 8, 9, 10 of large objects, movably mounted thereon means for moving the models towards a viewer 3 at predetermined speeds, a switch whereby the observer can stop the models when he judges they have a desired relative position and indicating means to indicate where those positions were so that the accuracy observer's sight and reaction can be assessed. In the embodiment shown the models are cars and are illuminated by a lamp 43 of variable intensity against a grey background 41. They are controlled by an electric motor acting on a shaft on which driving pulleys of varying diameters are mounted which drive belts in which the cars are mounted. Means are provided for varying the relative speeds of the cars, the individual simulated speeds of the cars (see scale 32), and for reversing them (see indicator 40). The cars may have headlights. Indicating means 34 are provided in the base to indicate the condition of the sight and reaction of an observer who is trying to stop the cars when they are in line which is in fact at point 35. The cars may be replaced by aeroplanes. A safety switch is provided to stop the models before they come to the end of a run and a light to indicate when the cars have passed a position beyond which the observer's error is too great.

Title: Means for indicating when the voltage of a battery falls below a pre-determined level
IPC: G11B5/00
Filed: 1960-11-18
Abstract: 897,836. Automatic speed-control systems. BOLKOW, L., [trading as BOLKOW-ENTWICKLUNGEN KOMM.-GES]. Nov. 18, 1960 [Nov. 24, 1959], No. 39720/60. Class 38 (4). [Also in Group XL (c)] In a supply system for a battery-driven constant speed motor M, e.g. for a portable recording machine, warning is given of low battery voltage V by an indicator L. The motor is controlled by a centrifugal switch S (closed at low speed) and a transistor Tr1 While the switch is closed voltage is applied also to a resistance-capacitance network R2, C2 but normally this is for a period below the time constant of the network so that negligible voltage appears at the base of a second transistor Tr. However, with falling battery voltage the ratio " closed to open " for switch S increases (to maintain the motor speed constant) so that the voltage on the base of Tr rises. Eventually the transistor conducts and the indicator L, e.g. a lamp, is operated.

Abstract: 1353234 Cooling nuclear reactor cores ASEA-ATOM AB 25 Aug 1971 [25 Aug 1970] 39780/71 Heading F4U [Also in Division G6] A nuclear reactor core 3 is cooled by a gas, e.g. helium, circulating in a first closed system by a turbine circulator 1 through a heat exchange system 5 and a reheater 9. The heat exchange system 5 comprises a main steam generator 7, auxiliary steam generator 8 and the reheater 9 and forms part of a secondary circuit wherein a portion of condensed water from a turbine condenser 12 is led to the generator 7 where it is vaporized, thus cooling the gas. The resultant steam is led in turn from the generator 7 through a line 13 to the high pressure side 16 of a main turbine 10, through a line 17 to the secondary side of the reheater 9, through a line 21 to a low pressure side of the turbine 10 and to the turbine condenser 12. A further portion of the condensed water from the condenser 12 passes to the steam generator 8 which is connected in parallel with the generator 7. Steam from the generator 8 passes to the reheater 9, and via a line 19 and a non-return valve 32 to the turbine 20 of the circulator 1. A portion of the steam produced in the generator 7 passes via a shunt valve 31 in a shunt conduit 30 to the turbine 20.

[Also in Division F2] A rotary table or the like of a machine tool, having locking means comprising two coneended pins 5 arranged on a diameter of the table, the pins being displaceable to engage complementarily shaped guide holes 22 in a base part 2 for the table, has each pin supported in a sleeve 17 which is displaceable to bring a slotted cone-shaped end portion thereof into firm engagement with a coneshaped guide 20 associated with the table, the arrangement being such that the displacing force exerted on the pin 5 reacts oppositely on the sleeve 17 the end 11 of which thereby contracts on to the pin 5 centralizing and clamping it firmly and accurately in relation to the table. Pinions 8 carried on a common manually rotatable shaft (7) engage rack portions 19 on the pins 5 for displacing the latter, the shaft (7) being supported in a tiltable bearing pedestal 9 carried by the table. Tilting of the pedestal 9 serves to transmit the reaction of the displacement force through self-aligning disc 12 and nut 13 to the sleeve 17.

Title: Improvements in or relating to the preservation of fruit
IPC: A23B7/16
Filed: 1963-10-16
Abstract: Climacteric exhibiting fruits such as bananas, avocados, pears and apples, are preserved by coating at least the stem portions of the fruit with a film of a glyceride having the formula : <FORM:0989928/A1-A3/1> where R1 is an acyl radical containing from 2 to 6 carbon atoms, R11 is an acyl radical containing from 8 to 24 (preferably from 14 to 20) carbon atoms and R111 is hydrogen or an acyl radical.  The preferred glyceride has a melting point of from 99 DEG  to 104 DEG F., a viscosity of 22 cps at 122 DEG F., an isotome value of 1 and a saponification number of 320.  The coating may be applied by dipping the desired portions of the fruit into a molten bath of the glyceride.  The fruit may have been previously coated with a fungicide or fungistatic agent or, alternatively, the fungicide or fungicide agent may be mixed with the glyceride in the weight ratio of 1:1000 before the glyceride is applied to the fruit. Fungicides mentioned are manganese or zinc ethylene bisdithiscarbonate, the co-ordination product of the zinc ion and manganese thylene bisdithiocarbonate, a mixture of the sodium salts of dimethyl dithiocarbamic acid and 2-mercap to benzothiazole, the sodium salt of dehydroacetic acid and tetramethyl thiuram disulphide. For certain fungicides, higher weight ratios than 1:1000 with respect to the glyceride are specified.  The glycerides are prepared by transesterifying fats or oils containing fatty acid groups with lower acylated glycerides in the presence of a catalyst, as disclosed in U.S.A. Specification 2,808,421.  The preferred glyceride, having the physical properties specified above, is obtained by acetylating approximately two-thirds of the free hydroxyl groups of hyrogenated lard monoglyceride.  Examples of suitable higher acylated triglycerides are trilaurin, trimyristin, tripalmitin, tristearin, triolein and the naturally-occurring triglycerides as are found in lard, beef tallow, cottonseed oil, soybean oil, peanut oil, coconut oil, palm oil, menhaden oil and corn oil. Lower acylated glycerides include triacetin (preferred), tripropionin, tributyrin, tri-isobutyrin, trivalerin and tricaproin.

Abstract: 1,236,841. Two-part couplings. AMP Inc. 18 Aug., 1969 [23 Sept., 1968], No. 41110/69. Heading H2E. An electrical connector comprises a body 2 having bosses 22, 24 near its end and a further body 4 having a hood 44 with radial extensions 50, 48 forming recesses 54, 52 to receive the bosses 22, 24 respectively. A locking ring 56 mounted on the hood 44 is rotatable about the axis of the hood to move the body 2 further into the hood and secure it therein by pressing against sloping rear faces 26 of the bosses. The body 2 contains socket contacts (12, Fig. 5, not shown) lying in axial through-passages 6 and crimped or otherwise secured to wires 14 retained on a flange 16 by a bundle strap 20. The body 4 contains corresponding pin contacts 32 in passages (30) and secured to wires 38. Both bodies 2, 4 are preferably moulded from a hard plastics such as a polycarbonate, polyvinyl chloride, nylon, or a modified polysulfone, and the ring 56 may be formed from a somewhat more rigid plastics or stamped from metal. In order to mount the ring 56 upon the hood 44, notches 68, 66 in the ring are aligned with the extensions 50, 48 whereupon the ring may be slid over the hood until on a level with slots (58, 60) running transversely through the extensions 50, 48. The ring may then be rotated by means of a hand tool so that an inner detent 70 on the ring is forced from axial groove 72 on the hood to groove 74. In this position, the ring is secured on the hood with notches (64, 62) aligned with the recesses 54, 52 to receive the bosses 22, 24, whereupon the ring may be further rotated by hand to move the detent 70 to another axial groove 76, releasably locking the body 2 in position. To polarize the two bodies, the boss 22 is made slightly wider than the boss 24.
