Patent GB-107087-A (GB)
IPC: B43K25/02
Abstract: 107,087. Tooker, H. R., and Tooker, H. L. July 3, 1916. Pockets, retaining pens and pencils in; attaching watch-chains and hand-bags to wearing-apparel.- A pen or pencil is retained in the pocket, or a watch fob or chain or lady's hand-bag is attached to the person, by a clip or holder comprising two parts capable of relative longitudinal movement, one of which has a spur or spurs to prevent removal of the pen by engaging with the fabric of the pocket. The other part of the clip has a shield to cover the spurs when it is desired to remove the pen. In Fig. 2, the spur 9 is shown carried by a sheet-metal plate 3 bent so as to clip the cap 2 of a pen and having guides 7, 8 for a sliding strip 12 which carries the shield 16. The plate 3 is formed with a bent tongue which interlocks with a groove 11 in the cap 2. The spur and shield are placed inside the pocket, the shield being operated to cover the spur by a part 13 of the strip 12 extending outside the pocket. In Fig. 6 the spur 24 shown is carried by a strip 20 riveted to the cap 2 and on which slides the shield 28, the spur and shield being arranged to bear on the outside of the pocket. The strip 20, instead of being riveted, may be provided with bent side wings to clip the cap 2, or it may be bent downwards and formed with an attachment plate opposite the spur. Instead of using a single spur, a foot with one or more rows of teeth or spurs may be used, or the spurs may be pivoted so as to be oscillated as the shields move. In one modification, the shield moves outwards to shield the spur.

Abstract: 1465883 Pressurized water nuclear reactor coolant flow circuit COMBUSTION ENG Inc 14 March 1975 [18 March 1974] 10771/75 Heading G6C A pressurized water, nuclear reactor, coolant flow circuit, comprises a pump for circulating coolant through the circuit and a coolant processing system through which a portion of the coolant is continuously passed to remove corrosion and fission products and to adjust the coolant's chemical composition, in which processing system relatively cool processed coolant from upstream of a regenerative heat exchanger is mixed with hot processed coolant from downstream of the regenerative heat exchanger before being injected into a system for sealing a shaft of the coolant pump, thereby to cool the sealing elements and to prevent the accumulation of foreign deposits. In the embodiment, Fig. 1, the coolant pump 12 is interposed in a line 10 of a primary coolant circuit. Part of the coolant is withdrawn along a line 14 and passes through the regenerative heat exchanger 46 (where it loses heat); throttle valve 48; letdown heat exchanger 50; back pressure valve 52; filter 54; boron-saturated, mixed bed resin ion exchanger 56 (for the removal of corrosion and fission products); (optionally) lines 62, 64 to a boron management sub-system; a volume control tank 58 (where hydrogen can be absorbed); and a pump 60 from where part of the flow is reheated in the regenerative heat exchanger 46 before being subdivided and fed to the line 10 in the primary coolant circuit and through a check valve 68 into a line 16 leading to the shaft seals of the pump, the other part of the flow from the pump 60 being led through a volume control valve 70 and a line 18 to be mixed with the higher temperature processed coolant in line 16 in a proportion regulated by a temperature sensor 72. Lithium hydroxide is added through line 66 to regulate the pH of the processed coolant. The seals of the shaft 30, Fig. 2, of the pump comprise a labyrinthine arrangement 32, 34 through which the mixed processed coolant from line 16 is diverted in opposite directions to escape through a bleed port 74 and past the impeller 24 to enter the outlet 28 of the pump.

Title: Improvements in or relating to the polymerization of diallyl phthalate
Inventor: HEIBERGER CHARLES ADAM
IPC: C08F18/08
Filed: 1958-04-09
Abstract: A solid diallyl phthalate prepolymer is prepared from diallyl phthalate by polymerizing at an elevated temperature, e.g. above 70 DEG  C., a mixture containing diallyl phthalate monomer, water, an organic peroxide or organic hydroperoxide catalyst, and a polymerization modifier of the formula <FORM:0861817/IV (a)/1> where X is chlorine or a hydroxyl radical or any group which can be converted to a hydroxyl group under reaction conditions, R is a methyl and/or ethyl and/or propyl radical, m is 0 to 4, the total number of carbon atoms in the R substituents is less than 5, and n is 0 to (4 - m), the modifier comprising 1 to 50% by weight based on the monomer, the reaction being discontinued before substantial gelation occurs by lowering the temperature below the polymerization temperature, unreacted monomer being separated from the prepolymer formed, and solid prepolymer recovered. Optional dispersing-agents, e.g. animal glue, clay and sodium tripolyphosphate, may be employed for the reaction.  When dimethyl benzyl chloride or dimethyl benzyl alcohol is used as polymerization modifier, optimum ratios by weight thereof to monomer are 1 : 3.5 and 1.4.  Other modifiers specified are benzyl alcohol and methyl-, isopropyl-, o-chlor-, and p-chlor-benzyl alcohols.  It is stated that the modifier apparently functions to control the chain length of the polymer; excess cross-linking does not occur and a prepolymer is obtained without gelation.  The proportion of water may be from 2 to 600% by weight of monomer. Catalysts in a proportion of 0.1 to 10% by weight of monomer are exemplified by benzoyl, acetyl benzoyl and succinyl peroxides and t-butyl perbenzoate.  Of the isomeric diallyl phthalates that may be employed, orthophthalates are preferred.  The prepolymers can be moulded to acetone-soluble thermoplastic or thermoset products at moderate temperatures and pressures.  Chopped fibres, magnesium oxide and wood flour may be incorporated in the cured prepolymer.

Abstract: 701,197. Steam turbines. AKT.-GES. BROWN, BOVERI, & CIE. May 5, 1952 [ May 9, 1951], No. 11286/52. Class 110 (3) In a steam turbine wherein admission is controlled by a number of nozzle valves starting is effected with all valves uniformly opened so as to avoid unequal heating of the turbine and when the change over to on-load operation is carried out the valves are automatically operated in succession. The regulating system employs an oil pump 1 supplying pipes 2, 3, the oil in pipe 2 passing through a throttling valve 17 to pipes 4, 10 and an escape valve 5 operated by the turbine governor 6. Branches 4a ... 4d are controlled by change-over three-way cocks 7a... 7d, with connections 16a ... 16d to powerpistons 8a ... 8d for operating the nozzle valves 9a ... 9d, and connections to pressure converters 11a . . . 11d each of which is also connected to the pipes 10, 3, throttle valves 18 being arranged in the connections to the pipe 3. Each pressure converter consists of a cylinder with a leakage port 15 and an escape port 14 controlled by a spring-loaded stepped piston 12. The power-pistons 8a ... 8d carry different spring loads so that when the change-over cocks 7a ... 7d are placed in position II the powerpistons are connected only to the pipe 4 and are automatically operated in succession. The ratio of the piston surface of each pressure converter is so selected that when at starting the changeover cocks are placed in position I the valves 9a ... 9b will all lift uniformly.
