Title: Handling grab
IPC: G21C19/105
Filed: 1971-06-10
Abstract: 1311383 Handling grabs for nuclear reactors ELECTRICITE DE FRANCE 10 June 1971 [31 July 1970] 19921/71 Heading B8H A handling grab for use in the environment of a nuclear reactor comprises a hollow cylindrical body 1 whose upper end is connected to a suspension and control unit (not shown), grappling claws 4 each being supported by two joined hollow metallic rods 6, 7 and the rods 7 being in contact with a passage 18. When the claws 4 are in the position of engagement shown in the left-hand side of Fig. 1 and it is desired to retract the claws 4 to permit their insertion in or retraction from an article, cold fluid is introduced through passage 18 into duct 7a of the rods 7 and out through slot 10 in the base 12. (For Figure see next column) The resulting contraction of the rods 7 relative to the associated rods 6 causes movement of the rods 6, 7 and claws 4 to the position of disengagement shown in the right-hand side of Fig. 1 in which the passageway 8 is almost completely closed. This reduces the circulation of cold fluid and the claws 4 slowly return to the position of engagement on being reheated due to the said reduction in the fluid circulation. In a second embodiment, Fig. 3 (not shown), the claws are removed inwardly to a position of engagement with a head (22).

Patent GB-614271-A (GB)
Title: Improvements in or relating to processes of rendering wool unshrinkable
IPC: D06M11/30
Filed: 1946-07-09
Abstract: Wool is rendered unshrinkable by treatment in an aqueous liquor containing a water-soluble bromate and hydrochloric acid, the concentration of the bromate being not smaller than the equivalent of 0.7 gm. of bromine per litre and the minimum concentration of the hydrochloric acid being governed by a formula which is itself dependent upon the bromate concentration and the temperature of the liquor, which temperature should not exceed 35 DEG  C.  Hydrochloric acid may be used as such or generated in situ from a chloride and another acid or acid salt, e.g. sulphuric acid or a bisulphate. Wetting agents, e.g. alkali lauryl sulphate or oleyl sulphate and protective colloids, e.g. glue or gum, may be added to the liquor. Woollen cloth may be milled during the treatment, in which case the acid and/or bromate may be present initially in reduced amount, the balance being added when the milling operation is interrupted.  The wool may be after-treated by, for example, rinsing, soaking in alkali bisulphite solution, washing with ammonia and again rinsing.  In examples, the bromate employed is potassium bromate and the temperature employed is 12 DEG , 25 DEG  and 35 DEG  C.

Title: Improvements in or relating to the mutual orientation of adjacent magnet poles
IPC: H01F7/20
Filed: 1966-05-10
Abstract: 1,131,138. Magnet poles. MASCHINENFABRIK OERLIKON. 10 May, 1966 [11 May, 1965], No. 20334/66. Heading H1P. The poles of a magnet used e.g. in nuclear resonance spectroscopy are made adjustable for parallelism to compensate for deformation of the yoke, by magnetic attraction between the poles by rotatably attaching a wedge-shaped intermediate support member 3 (Fig. 1) to the face of yoke stator 1 by captive screw 9, while a polepiece 5 is rotatably attached to the support member. The respective front and rear surfaces of the polepiece and support member are inclined to each other at a small angle so that on rotation e.g. by tangent screws and peripheral worms (Fig. 4, not shown) the inclination of the pole face to a plane normal to the yoke axis 15 is adjustable through a small angle. The polepiece and support member may be adjusted by coaxial shafts attached thereto (Fig. 5, not shown) and may be rotatably retained in contact by peripheral keep rings (Figs. 6, 7, not shown). The polepieces may have detachable or integral shaped poletips (Figs. 8, 9, not shown). The polepieces (Fig. 10, not shown) may be automatically adjusted to parallelism in response to a detector probe therebetween responsive to the magnetic field at two displaced positions in a plane parallel to the pole faces; resultant signals being recorded and compared with signals representing theoretical values. The error signals control adjusting means for the polepieces and support members for equality of field at the probes.

Title: Control switch for cycling and defrosting refrigerating apparatus
Inventor: LIEBERMANN JOHN
IPC: H01H35/26
Filed: 1964-05-19
Abstract: 1,012,788. Thermal switches. RANCO Inc. May 19, 1964, No. 20685/64. Heading H2B. A refrigerator control switch, basically similar to that disclosed in Specification 942,106, has additional snap-action means 106, 108 and contacts 55, 61 (Fig. 7) for defrosting, which contacts are closed by manual operation of a button P at the centre of the normal control knob K and opened by the thermally responsive element 86 at a temperature appreciably above the normal cycling temperatures of the main contacts 67, 72 due to the said snap-action means also imposing additional spring-loading on the thermal element when defrosting is initiated. The toggle 106 (pivoted at 107) and overcentre spring 108 are normally in the position shown in Fig. 7, and an extension 116a of the toggle 106 holds contact 61 away from contact 55. When button P and thus rod 105 are depressed the end 105a snaps the toggle 106 and spring 108 into the position shown in Fig. 14, allowing contacts 55, 61 to close (Fig. 11, hot shown), and a tab 106f is urged against a tab 83d on the end of main lever 83 (pivoted at 84) thereby adding to the force exerted by spring 90 against capsule 86 via the nose 83b. Therefore a relatively high temperature is necessary before capsule 86 moves lever 83 clockwise to snap main contacts 67, 72 into engagement and to restore the snap mechanism 106, 108 by tab 83d acting on tab 106f. The final defrost temperature is adjustable by means of screw 109, and is rendered substantially independent of the setting of knob K by means of a compensating spring 120 which extends from the cam follower 94 to the toggle 106 such that increase in tension of main spring 90 is offset under defrost conditions by spring 120 reducing the additional force exerted on tab 83d by spring 108. The contacts 55, 61 may be used to-energize a heater in the evaporator of the refrigerator (Fig. 13, not shown), but if it is desired to defrost by diverting hot compressed refrigerator gases to the evaporator a solenoid valve is used and it is necessary for the compressor to run during defrost. To this end a nose 106e (Fig. 7) is provided on toggle 106 to engage a projection 118 on member 82 and depress the latter away from lever 83, thereby maintaining contacts 67, 72 closed (Fig. 10, not shown) while defrosting.

Abstract: 383,978. Toy firearms. SCOTT, R. W., 19, Manor Road, Beckenham, Kent, and GUITERMAN & CO., Ltd., S., 35, Aldermanbury, London . July 20, 1931, No. 20749. [Class 132 (iii).] Toy firearms comprise an operating shaft 7 rotated by means of a handle 8 and provided with a cam 9 having two cam surfaces 10, 17, the surface 10 being adapted to operate a percussion hammer 12 pivoted at 13 by arrangement with a projection 11 thereon, while the surface 17 operates a lever 19 pivoted at 20, the free end of which engages the face of a strip of caps so as to feed the strip intermittently through the firearm in correlation with the working of the hammer 12. The mechanism is arranged in the body portion 2 of the firearm, one side 2a of which is detachably clamped thereto by bolts 28, 29, the latter bolt also serving to secure in position the barrel 1 of the firearm. The body portion 2 is mounted on a base 3 by means of a universal joint 4. The hammer 12 is urged downwardly towards a platform 31, on which the cap strip rests while being fed through the body 2 at slots 27, by the action of a spring 16 carried in a vertical hole 16 therein. The lever 19 is provided with a pin 18 which engages the cam surface 17, while the head 23 of the pin engages a further internal cam surface 24 on the cam 9 to cause the lever 19 to be lifted each time it is moved backwards to engage a fresh portion of the cap strip. The lever 19, which is provided with an external finger grip 26, is restored to its original position under the action of a helical spring 21 which encircles the bolt 28, and presses against a projection 22 on the lever 19. According to the Provisional Specification the invention may be applied to toy pistols, and cams operated by a ratchet mechanism controlled by a trigger, or arranged to operate with a reciprocating motion may be employed.
