Title: Hydrostatic transmission
Inventor: COOK RONALD ALAN
IPC: F16H47/02
Filed: 1963-09-20
Abstract: 1,004,050. Hydraulic transmission of power. FORD MOTOR CO. Ltd. July 17, 1964 [Sept. 20, 1963], No. 37006/63. Heading F2C. In a variable-speed hydrostatic drive for a motor vehicle comprising a pump 1 and a motor 3 having parallel axes of rotation, each comprising a cylinder and piston member and a swashplate member, one member of the pump is drivingly connected to an input shaft 7 and the other member is coaxial with and drivingly connected to an output shaft 15, while one member of the motor is non-rotatable and the other is rotatable and is geared to the output shaft 15 by meshed gears 21, 23, 25. As shown the pump cylinder and piston member 5 is connected to the input shaft 7, the swash-plate member 13 being carried by the output shaft 15. The motor swash-plate 17 is pivotally mounted in a casing (not shown) and the piston and cylinder member 16 rotates, the pump and motor being hydraulically connected. On starting, with the motor swash-plate 17 inclined, substantially the whole drive torque is transmitted hydraulically to the motor 3 and through gears 21, 23, 25 to the output shaft. As the inclination of the motor swash-plate is reduced the drive is progressively taken up by the pump swash-plate 13 until when the swash-plate 17 is normal to the axis of rotation of the motor, direct drive through the pump is obtained, the gear train 21, 23, 25 being unloaded.

Title: Improvements in piles of moderator and/or reflector elements for nuclear reactors
Inventor: ROCHE ROLAND LOUIS
IPC: G21C5/08
Filed: 1957-11-27
Abstract: 822,788. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 27, 1957 [Dec. 3, 1956], No. 37010/57. Class 39(4). The moderator structure of a nuclear reactor comprises a number of vertical columns having flat vertical side walls, the columns being juxtaposed close to but out of contact with one another, each of the columns consisting of a number of horizontal layers superimposed on one another, each of the layers consisting of a number of blocks disposed parallel to and at a small distance from one another, the longitudinal direction of the blocks of one layer being transverse, and preferably at right angles to, the longitudinal direction of the blocks of the next layer, each of the blocks being guided with respect to at least one of the blocks of the layer beneath by connecting means capable of keeping the longitudinal directions of the two blocks at a constant angle without interfering with expansion or contraction of the blocks. Fig. 4 shows a cross-section of one of the columns forming the moderator structure. The base of the column rests on a cast iron plate 2 supported from a steel floor, and the column comprises layers each containing five graphite bricks separated from each other by small spaces. Each brick is pivotally connected to the centre brick of the layer underneath by means of sleeves 18 ; each brick is also slidably connected with the end brick of the layer underneath by a sliding key 20, shown in Fig. 8. The sleeves 18 and keys 20 are preferably graphite but may be of beryllium, zirconium or beryllia. The bottom row of bricks is similarly connected to the supporting plate 2, but the sleeves and keys may in this case be of steel. The column is provided with a number of vertical fuel channels which are aligned with holes in the plate 2. The construction described allows the graphite to expand and contract due to Wignes growth without imposing excessive stresses on the structure.

Title: Method for producing members for a slide fastener
Inventor: SUTTON FRANCIS PAUL
IPC: B21D53/52
Filed: 1954-12-22
Abstract: 775,702. Making sliding clasp fasteners. LIGHTNING FASTENERS, Ltd. Dec. 16, 1955 [Dec. 22, 1954], No. 37012/54. Class 83 (2). A process for making components of sliding clasp fasteners comprises feeding a metal strip to a punch which forms locating holes serving partly to define the outline of each component, registering the strip with respect to shearing means by use of the locating-holes and then shearing the strip between certain of the locating holes to produce two separable intermediate members each comprising a series of spaced partly-formed components bridged by a connecting-strip from which the components are subsequently severed. The formation of interlocking members is shown in Figs. 1 and 2. Holes 2 are first punched in the strip which is then sheared along lines 4 to form two intermediate members one of which, 5, is shown. Each interlocking member is completed by indenting at 6 and shearing along the line 8. Anodizing or other electrolytic treatment may be applied prior or subsequent to the indenting. Figs. 4 and 5 show the making of slider pulls, a strip being punched first with locating holes 11 and then with further holes 12 and 13 before being cut along the line 14 to form an intermediate strip 15 from which the pulls are severed along lines 16. Slider body plates are made by punching holes 21, Fig. 7, depressing the areas 22 within the dotted line 23, forming narrow slits 24, raising the portion therebetween and then shearing along lines 25 to form the strip shown in Fig. 8. The plates are completed by bending down the sides along the lines 26 and shearing along the lines 23. Half elements of open-box end stops are formed by punching holes 31, Fig. 10, shearing along lines 32 to form the intermediate strip, Fig. 11, which is bent along lines 36 and sheared at 37. Where anodizing or other surface treatment is applied, it is carried out before the individual components are severed from the intermediate strip and the components are of such shape that the surfaces newly exposed by such severing are those which become substantially concealed from view after assembly of the components in a slide fastener.

Abstract: 1288004 Scoring capillary tubes GILFORD INSTRUMENT LABORATORIES Inc 31 July 1970 [18 Aug 1969] 37158/70 Heading C1M Apparatus for feeding and cutting capillary tubes 26 comprises a support structure 12 upon which is mounted a reciprocable carriage 14 biased in one direction by a spring 16, a guiding element 24 on the carriage 14 for laterally confining the capillary tube 26, a first unilateral grab mechanism 28 on the carriage 14 which permits the tube to slide relative to the carriage when the carriage is moved upwardly but engages the tube when the carriage moves downwardly and a second unilateral grab mechanism 32 mounted on the support 12 which engages the tube only when the carriage is moved upwardly, so that downward movement of the carriage feeds the tube 26 downwardly but the return movement leaves the tubes position unaffected. A scoring wheel 34 is mounted on a swinging arm 36. A length of tube is broken off by laterally straining the tube by means of a yoke 50 or by merely tipping cuvette 48 which is to receive the length. A grab control mechanism is provided to render the grab mechanism inoperative when it is necessary to insert a fresh tube. The movement of the arm 36 may be controlled by the movement of the carriage 14.

Patent GB-378516-A (GB)
Abstract: 378,516. Supplying consuming devices. WILSON, H. G. A. R., Davenset Works, Evington Valley Road, Leicester. May 15, 1931, No. 14396. [Class 38 (iv).] Charging batteries ; switching systems.- Relates to a self-contained unit which draws current from a source and, if necessary, rectifies the current and supplies it to one or more loads (e.g. batteries to be charged) and consists in having indicator lights in association with each output circuit, one to show when the circuit is energized but not in use, the other to show when the circuit is in use, and a relay responsive to current flow in the circuit for controlling the lamps. The output terminals 2, Fig. 1, are connected to the source of energy 1 via a switch 5, the operating coil 9 of a relay 17 and barretters 27 for limiting the current. When switches 5, 20 are closed lamp 6 will light if no load is connected to the output terminals. 2, but if a load is connected the relay will operate and lamp 7 will light. In the form shown in Fig. 2, two values of current can be obtained from the output terminals 2 according to the position of a switch 37a, a lamp 7 showing when the lower value of current is being taken and a lamp 7a showing when the higher value is being taken. When the switch is in the position shown current can flow through the lead 26 only, but when the switch is in the other position current can flow through lead 34 also to give a higher current output. Fig. 5 show a construction of relay. The plunger 8 of a solenoid 9 normally presses a springy armature 10 into engagement with a contact 11. Energization of the solenoid lifts the plunger and the armature 10 makes contact with a bridge-piece carrying a contact 12.
