Title: Lock nut and bolt assembly
Inventor: GREENWOOD EUGENE CRANE
IPC: B25B13/04
Filed: 1969-11-20
Abstract: 1,254,149. Locking nuts. E. C. GREENWOOD. 20 Nov., 1969 [12 Dec., 1968], No. 56948/69. Heading F2H. A lock nut and bolt assembly comprises a bolt 5 with a longitudinal goove 6, an annulus or lock ring 12 having radially outwardly extending serrations 13 and an inwardly extending tongue 14 which engages in the groove 6, and a nut 2 with an axial hole having three sections, the first threaded to mate with the threads of the bolt, the second 10 serrated to engage the serrations on the annulus and the third section plain in which the annulus can rotate freely. In use, the annulus is depressed against spring 16 into the plain portion of the nut hole whilst the nut is screwed down using special tool 21. When the nut is fast, the tool is removed and the annulus permitted to engage the serration of the nut to prevent its rotation relative to the bolt. Flange (17, Fig. 2, not shown) prevents loss of the annulus.
Patent GB-570640-A (GB)
Abstract: 570,640. Electric cables. SONNENFELD, H. Oct. 26, 1943, No. 17587. Drawings to Specification. [Class 36] An electric power cable has an external elastic sheath under tension at normal temperatures so as to apply compression to the core which consists of extruded rubber or thermoplastic. The tension may be obtained by extruding the sheath whilst the core is cooled below normal temperature or by wrapping strips of elastic material under appropriate tension. The sheath may consist of a thermoplastic material, e.g. cellulose esters or polystyrene &c., mixed with plasticizers and the core is passed through a refrigerating chamber to effect the cooling. The sheath may comprise an oil-resistant synthetic rubber compound, applied by extrusion or as a wrapping strip. The cable may be evacuated and air, gas or oil pumped in under such a pressure as to cause a non-circutar cable to become circular. Specifications 406,704, 479,883 and 499,311 are referred to.

Title: Grinding machine
IPC: B24B49/18
Filed: 1969-03-24
Abstract: 1,274,946. Grinding. HEALD MACHINE CO. 24 March, 1969 [1 April, 1968], No. 58755/71. Divided out of 1,274,945. Heading B3D. A grinding machine 10 comprises a base 11, a workhead 12 mounted on the base to support and rotate a workpiece 23, e.g. a ball-bearing race, having a surface of revolution to be finished, a wheelhead 13 mounted on the base and having a rotatable spindle 21 carrying an abrasive wheel 22, and feed apparatus to bring about relative movement of the workhead and wheelhead to introduce the wheel to the workpiece with controlled force for performing a grinding operation to finish the said surface, Means are also provided for monitoring during grinding the relationship between the grinding force (F N ) exerted by the wheel on the workpiece normal to the surface of revolution and the plunge velocity (V) and operative when the ratio of the plunge velocity to the normal force indicative of wheel dullness falls below a certain predetermined value to bring about renewal or dressing of the wheel surface. In the machine shown, the workhead 12 is carried on a table 14 slidable longitudinally of the base 11 under the action of a fluid feed cylinder 19, and is driven by a belt 48 from a motor 47. The wheelhead 13 is carried on a table 16 slidable transversely of the base 11 under the action of a feed cylinder 18 supplied with fluid from a conduit 42. The normal force F N  between the wheel and the workpiece is measured from the pressure in conduit 42 by a transducer 46. Alternatively F N  is measured by a force transducer such as a proximity pick-up adjacent the spindle 21 which operates an amplifier 56. The plunge velocity V is indicated by an amplifier 41 operated by a velocity transducer comprising a core 38, on table 16, and a fixed coil 39. Electrical circuitry is provided in a main control which compares the ratio # = V/F N  with a predetermined value # 0 . When # becomes less than # 0  a signal is generated either to a coil 55 which causes grinding to be interrupted and a tool 29 to dress the wheel 22, or to a coil 45 which opens a valve 44 to permit a pulse of fluid to the cylinder 18 thus urging the wheel 22 against the workpiece to crush-dress it.

Title: Device for indicating state of storage of deep-frozen products
IPC: G01K11/08
Filed: 1968-12-19
Abstract: 1,245,135. Temperature indicators. STUDIENGESELLSCHAFT KOHLE m. b. H. Dec. 19, 1968 [Dec. 23, 1967], No. 60351/ 68. Heading G1D. A temperature indicator for frozen foodstuffs which gives an irreversible indication of the temperature of the foodstuff has risen above a predetermined limit during storage comprises a closed thin-walled vessel 1 made of a brittle material e. g. glass or polystyrene, and containing a liquid 2, preferably aqueous, which expands when solidifying to break the vessel 1, a porous material 3, e. g. cotton wool, surrounding the vessel 1 and enclosed in a transparent closed jacket 4, and an indicator 5 e. g. a water soluble dye impregnated on a disc of filter paper, so that if the ambient temperature rises above the freezing point of the liquid 2, the porous material 3 will become coloured due to the interaction of the liquid and the dye of the indicator. The liquid 2 is preferably an aqueous solution of an inorganic or organic material and non-toxic. In particular salts of sodium, potassium, ammonium or calcium may be used preferably as a eutectic mixture which melts at a precisely defined temperature. Inplace of the disc of dye-impregnated filter paper, the dye may be loose in the jacket 4, or alternatively may be dissolved in the liquid in the vessel 1. In some cases the dye itself may function as the substance depressing the freezing point of the liquid, or in cases where a coloured inorganic salt is used the dye may be dispensed with completely. The liquid from the vessel 1 may also be such as to react with a substance added to the porous material 3 leading to a visible change e. g. the liquid may be alkaline and the porous material contain phenolphthalein. Any dry dye present in the jacket 4 may be masked by white blotter paper so as to give a clearer indication of the melting of the contents of the vessel 1.

The protective gas, which may absorb dissolved gases from the metal (although the latter may have been vacuum-degassed), enters through a tube 20 in a plate 14 which may be fixed to the mould top and includes a sampling tube 21. The box 15 resting on the plate 14 is formed in two halves 15a, 15b, separable to provide access to the nozzle, and one half has an observation window 19. Relative dimensions and a gas flow rate are given.
