The tubular cover may be longitudinally divided into two or more sections adapted to co-operate with one another and to be fitted around the pipes where they are fixed together by, e.g. external strapping 10. The cover may be spaced away from the pipes by distance pieces 11, 12, 13, 14, 15 provided with pathways through them or by internal ribs on the cover made to form a helical passage between the pipes and the cover to allow the resin to easily fill the whole of the cavity. The unsaturated polyester based material may comprise an unsaturated polyester, an ethylenically unsaturated monomer copolymerizable therewith, e.g. styrene, a free radical vinyl polymerization catalyst and a mineral filler, e.g. particulate silica. The resin to filler weight ratio may be between 1 : 7 to 1 : 15.

Title: Improvements in or relating to a process and apparatus for the manufacture of glass articles
IPC: H01J37/30
Filed: 1965-12-10
Abstract: <PICT:1114605/C1/1> In the pressing of glass articles such as chalice stems and feet, a predetermined amount of molten glass is fed to a cavity in a mould and suction is applied to the mould through an orifice in the bottom thereof, the size of the orifice being reduced as the molten glass approaches the orifice.  An annular suction distribution (2), rigidly suspended from a rotatable table 1, has suction connectors (3) communicating through flexible hoses 4 with each mould assembly S positioned around the table 1.  Each assembly S consists of a mould 11 and ram 12 movable into a cavity 13 which leads to a stem cavity 16 into which a vertically movable member 15 fits, suction being applied through an axial passage 18a to suction holes 18 below the head 15a and the head 15a being moved upwards to reduce the gap between the mould cavity 16 and the head 15a as the molten glass approaches.  The member 15 is urged upwardly by a spring 21 and is lowered by a compressed-air cylinder 24 connected by a guide housing to the base extension 15b.  At each turn of the table 1 the extension 15b of a member 15 of an assembly S moves into the housing 22 and as the gob falls into the cavity 13, the cylinder 24 is operated to lower the head 15a. As the cavity fills, the head 15a is raised by cylinder 24 but suction is still applied through the minimal gap between head 15a and cavity 16 until the mould 11 moves to the next position when the ram 12 is operated.  A manual control 30 may be used to inactivate an assembly S and discharge the gob of glass elsewhere. A similar mould assembly is disclosed which also incorporates an ejector mechanism.

Abstract: 1,217,754. Printing plates. FMC CORP. Nov.11, 1968 [Dec. 14, 1967], No.53253/68. Headings G2C and G2M. A method of forming a polymeric image comprises applying to a base material a thermally cross-linkable allylic resin obtained by the polymerization of an addition polymerizable allyl carboxylic ester having a plurality of aliphatic ethylenically unsaturated linkages at least one of which is in an allyl ester group, heat curing the resin layer, and exposing the resin layer to a heat pattern thereby effecting removal of the cured resin in the heated areas while leaving an image of cured resin in the unheated areas. Preferably the base is a metal and the based metal areas obtained by development are desensitized.

Title: Fluid-Flow Control Valve
Inventor: FANSHAWE HEW DALRYMPLE
IPC: F04B9/107
Filed: 1966-12-02
Abstract: 1,159,427. Valves. F.N.R.D. Ltd. 23 Feb., 1968 [2 Dec., 1966], No. 54160/66. Heading F2V. A valve which can be used to remove excess buffer fluid from a piston-operated diaphragm pump or as a metering device has a partition member 4 slidable in a hollow body 1 and providing a seat 13 for a spring-loaded inlet valve closure member 8 having a passage 11 connecting pressurized fluid in chamber 23 with the bore 18 of the partition member. A spigot 17 is sealingly slidable in the bore 18 and provides an outlet passage 19 that can be closed by movement to the left of the partition member which is biased to a rest position shown by a spring 22. Movement of the closure member 8 to the right by, e.g. a flexible hauling element connected to the pump diaphragm on excess travel of the diaphragm opens the inlet valve to allow fluid pressure from chamber 23 to flow into chamber 6 which displaces partition member 4 to the left to push fluid out of chamber 5 through the outlet passage 19. The inlet valve remains open due to the flow into the chamber 6 until the partition member 4 stops moving after it has closed outlet passage 19. After which the inlet valve is closed by spring 16 due to the flow into chamber 6 closing when the partition member stops moving to the left. The spring 22 then returns the partition member to its rest position with the inlet valve remaining shut. Leakage through passage 7A between the partition member 4 and the hollow body 1 and through restriction 7 allows fluid to pass from chamber 6 into chamber 5 on movement to the right of partition member 4. A substantially predetermined volume of fluid is displaced from chamber 5 during movement to the left of partition member 4 but the actual amount depends on the speed and pressure of the partition member 4 and the size of the passages 7, 7A which also allow fluid to pass from chamber 5 to chamber 6 during this movement of the partition member.

Title: Improvements in and relating to electrical rate-measuring circuits
IPC: G01P3/48
Filed: 1968-11-21
Abstract: 1,207,558. Pulse rate measuring. D. OLIVETTI & C S.p.A. 21 Nov., 1968 [24 Nov., 1967], No. 55197/68. Heading H3A. A rate measuring circuit comprises: a Zener diode D2, for holding a reference point A at a stabilized voltage; a capacitance C2 connected between the reference point and a transistor T1; and a control circuit S1 operated at the rate to be measured to switch the Zener diode D2 out of its breakdown region to apply a lower voltage to point A whereby the transistor T1 is switched into a set condition, the base voltage of the transistor T1 then changing exponentially until the transistor switches back to a reset condition whereby the length of time the transistor T1 is in its set condition is dependent on the magnitude of the step voltage, and thus inversely dependent on the supply voltage. When switch S is open point A is at potential determined by Zener diode D2, and point B is slightly above earth causing transistor T1 to conduct. When switch S closes, point A falls (to potential R 1 /(R 1  + R 3 )Va) taking point B with it to cut off transistor T1. Point B now rises towards Va as capacitor C charges through R 4 , R 5  until transistor T1 switches on again. The time during which transistor T1 is conductive thus reduces as Va increases, so that the average current through meter I may be made independent of Va. In a modification, Fig. 2 (not shown), diode D1 is replaced by a transistor (T2).

In the case of the low temperature baking at 350-500F the mould may be rubber, plastics or paper and the baked preform may then be sintered and directly forged or re-heated after sintering and forged. Similarly the preforms sintered in metal or ceramic moulds are either forged directly or re-heated and forged. The process is particularly applicable to water atomized ferrous powders which are sintered and forged into differential gears.
