Abstract: 1,220,676. Reshaping glassware. QUICKFITT & QUARTZ Ltd., and D. CURTIS. 21 March, 1968 [23 March, 1967], No. 13818/67. Heading C1M. Apparatus for developing an internal precision sealing surface in a hollow glass body 9, comprises a vertically mounted mandrel 1 with the requisite external configuration and an axial bore 3 mounted on a member 17, which forms part of a rotating mechanism, a centre pin 2 having a bore registering with bore 3 mounted on the mandrel 1 and a spindle 4 for supporting the body 9 fitting over the pin 2 and with radial bores 5 which connect with the bore 3. The rim 11 of the body 9 is heated by burner 12 and pressed into contact with the rotating mandrel 1, as by a roller 13. Suction is then applied to the bore 3 and the burner 12 raised to heat the remainder of the area 10 of the body 9 successively so that the area 10 is pulled by the suction into contact with the mandrel 1. For open-ended tubes, as shown, the spindle 4 is provided with a compressible rubber block 6 apertured at 7 to be a tight fit over spindle 4 and grip the tube 9. The mandrel 1 is of stainless steel of coefficient of thermal expansion greater than that of the glass so that on cooling, the mandrel is readily removable.

Abstract: 697,794. Lifting trucks. MONTGOMERY, F. M. May 31, 1951. [June 5, 1950] No. 14033/50. Class 78 (iii). In a lifting truck rollers are mounted on supports pivoted close to the forward end of the platform the rollers lying between the pivots and the rear end of the platform and the tilting of the supports to lower the rollers to the ground on raising the platform is effected by a rod attached to each support above its pivot and extending along the platform to a cam and follower connection. The fork arms 11 of a truck are mounted on spaced channelled uprights 23 and are raised by a hydraulic cylinder, the uprights being guided on rollers 35, 36 on an inner pair of uprights mounted on wheels 34. Rollers 18 and 20 to 22 are mounted on a support pivoted at 17 to each fork arm. The support is connected by a rod 19 to the base of a lever 44 pivoted to the upright 23. The stub axles carrying the rollers 36 also carry cam rollers 48 which when the platform is raised engage a cam surface 46 on the levers to cause the levers to pivot and operate the rods 19 to rotate the supports and raise the fork ends. The speed of the descent of the rollers can be arranged by the shape of the cam surface to be rapid at first then slower as the rollers press against the ground and then more rapid. Alternatively, the cam levers may be pivoted on the wheeled frame and the cam follower mounted on the platform. Specification 638,601 is referred to.

Abstract: 1427481 Locating faults in cables HOWALDTSWERKE-DEUTSCHE WERFT A G HAMBURG UND KIEL 29 March 1974 [6 April 1973] 14046/74 Heading G1U A high impedance fault 12, Fig. 1, in a telecommunication cable, caused by the ingress of moisture, is located by capacitively coupling a pulse train to the cable from a source 2, 5 and by contrasting the resulting pattern of reflected pulses obtained (a) when a D.C. polarizing voltage from a source 3 is applied across the fault and (b) when no polarizing voltage is applied across the fault. Since the polarizing voltage will only change the reflecting characteristic of the fault region (electrolytic effects changing the effective fault impedance) the difference between these two pulse patterns will enable the distance of the fault from the end of the cable to be derived.

Title: Improvements in the production of polyurethanes
Inventor: SHELANSKI MORRIS VICTOR
IPC: C08J9/00
Filed: 1963-04-11
Abstract: A polyurethane suitable for the manufacture of foams and films ia prepared by reacting in the presence of dimethyl formamide as catalyst an organic diisocyanate with a surfactant having alternately connected hydrophobic and hydrophilic portions wherein each hydrophobic portion has at least one hydrophilic portion connected to it, each hydrophilic portion comprising an ethylene oxide chain terminating in an hydroxyl group and each being individually linked to a hydrophobic portion, the proportions of the reactants being such that the final product when cured to a foam or cast in a film has an ethylene oxide content of 30 to 80% by weight.  The hydrophobic portion may be a propylene oxide polymer, ethylene diamine to which 1:2 propylene oxide has been added, alkylphosphate, alkyl amide, dicarboxy fatty acid alkyl, and dihydroxy fatty acid alkyl. The surfactant may be an Ethomid (an NN substituted fatty acid amide, the substituents being polyoxyethylene groups), a "Pluronic" (R.T.M.) made by condensing ethylene oxide with a hydrophobic base formed by the condensation of 1:2-propylene oxide and propylene glycol, and "Tetronic" (R.T.M.) which is similar to "Pluronics" except the initial material is ethylene diamine.  A dihydric alcohol, e.g. butene-1,4-diol or polyoxypropylene glycol, may be added to the reaction mixture to increase the tear resistance of the final product.  In a typical Example (1) Ethomid HT/60 was reacted with tolylene diisocyanate for about 1 hour at 110 DEG  C., cooled and more tolylene diisocyanate together with dimethyl formamide and Ethomid HT/60 are added. To the prepolymer thus prepared water was added and the foam cured at 70 DEG  C.

Abstract: 875,556. Photo-electric exposure control. KODAK Ltd. April 28, 1960 [April 29, 1959], No. 14850/60. Class 40(3) [Also in Group XX] In a camera in which exposure factors are automatically set by the position of a moving part of an exposure meter, a manual override is provided by two driving members which on movement of a control member clamp the moving part and move it to a desired position. For automatic control nothing obstructs the rotation of the ear 46 which is connected to the photoelectrically energized moving coil 21. For manual setting, the disc 32 is rotated anticlockwise. The lug 38 releases the leaf spring 40 which clamps ear 46 against the lug 52. Further rotation of the disc 32 sets the arm 48 to any desired position. A lug 56 co-operating with the slot 54 prevents excessive rotation of disc 32.
