Title: Polymers of alkalene diperoxyesters
IPC: C08F22/20
Filed: 1968-03-08
Abstract: 1,217,407. Polymers of alkylene diperoxyesters. WALLACE & TIERNAN Inc. 8 March, 1968 [17 March, 1967], No. 11570/68. Headings C3G and C3P. A homo- or copolymer is formed by heating at a temperature between -30 and +80 C. a peroxyester monomer of general formula for a time sufficient to form a polymer characterized by the presence of pendant peroxyester groups, where (a) [A] is the radical (b) P is the radical (c) m and n are zero or 1; (d) R 1  and R 2  are alkylene radicals having I to 6 carbon atoms; (e) R 3  is the radical lower t-alkyl, cycloalkyl at a t-carbon atom, cycloalkyl - lower - t - alkyl, or ar - lower - t - alkyl; (f) R 4  is the radical having a t-carbon atom joined to peroxy oxygen o<SP>1</SP> and a t-carbon atom joined to peroxy oxygen o<SP>11</SP>, said radical R 4  being alkylene, alkenylene, or alkynylene having 3 to 12 carbon atoms and (g) R 5  is the radical H, lower - t - alkyl, or - lowert - alkyl, lower acyl or lower carbonate, said peroxyester monomer being heated alone or in admixture with an ethylenically unsaturated monomer capable of being polymerized by free radical polymerization, in which latter case the temperature employed is between -60 and + 80 C. The homo- or copolymer formed may be subjected to a grafting process, or used as a polymerization initiator or as a curing agent for an unsaturated polyester-vinyl monomer system. Specified diperoxyesters are di(t-butylperoxy) fumarate, mesaconate and itaconate and di- (cumylperoxy) itaconate. Examples are given of the homopolymerization of di(t - butylperoxy) fumarate (DTBPF) in solution in benzene and of the copolymerization of DTBPF with styrene, vinyl acetate, vinyl chloride, butadiene, acrylonitrile or methyl methacrylate. Graft polymers are formed by grafting styrene on to a DTBPF/vinyl acetate copolymer, methyl methacrylate on to a DTBPF/styrene copolymer (a graft-block copolymer is formed), styrene and acrylonitrile on to a DTBPF/butadiene copolymer and butadiene on to a DTBPF/ styrene/acrylonitrile terpolymer. The DTBPF homopolymer or DTBPF/styrene copolymer is used to cure a maleic anhydride-phthalic anhydride-propylene glycol polyester/styrene mixture. In Example 14, DTBPF/styrene copolymer is used as initiator in the bulk polymerization of styrene. The graft polymers may be used to stabilize dispersions of 2 different polymers, for instance in Example 11 a DTBPF/ styrene copolymer grafted with methyl methacrylate acts as stabilizer for a dispersion of polystyrene and polymethyl methacrylate in chloroform and a DTBPF/vinyl acetate copolymer grafted with styrene is added to a dispersion of polystyrene and polyvinyl alcohol in benzene.

Title: Improvements in or relating to the measurement of consistency
Inventor: LUND HAROLD HOWARD
IPC: G05D24/02
Filed: 1962-03-27
Abstract: 951,848. Mixing controlled by viscosity. NATIONAL CLAY PIPE-RESEARCH CORPORATION. March 27, 1962, No; 11713/62. Heading B1C. [Also in Divisions G1 and G3] The consistency of a mouldable material, e.g. clay, plastics, rubber, candy, soap or the like, is measured by sensing the presssure on a feeler extending into the material which is moving at constant linear velocity. The measurement is used to control the admission of additional liquid to maintain the consistency constant. As shown, clay in a pug mill 11 is mixed with water from a main nozzle 13 and a fine, controlled, nozzle 41, the mixture being forced through orifices defined-by sealing dies 22, 23 into a vacuum chamber 19 from whence it is extruded through a die 21 to form bricks, tile or pipe. Secured in the orifices are four transducers 30-33, each comprising a spring- loaded plunger attached to the movable core of a differential transformer, the output of each being connected in bridge fashion across a potentiometer to provide an adjustable null position, Fig. 3 (not shown). The output of each bridge is thus an A.C. voltage of magnitude dependent on consistency, and phase sense according to whether this is above or below a desired level. The four outputs are connected in series to give an averaging effect, and the result amplified in a cascode amplifier 36, Fig. 4 (not shown), and applied to a phase discriminator 37, Fig. 5 (not shown. The output of this operates relays 38, Fig. 6 (not shown), to control a reversible motor 39 connected to a valve 40 in the water supply to the fine nozzle 41. Indicator lamps show when conditions are balanced, when the valve is being opened or closed, and if it reaches the end of its travel, when manual adjustment is made to main nozzle valve 43.

Patent GB-1032105-A (GB)
Title: Small spherical particles and their production
IPC: C01G43/025
Filed: 1963-03-26
Abstract: Spherical particles of a substance which can be dispersed as a sol are made by forming spherical droplets of a sol of the substance in a boiling stirred immiscible liquid medium which has a density greater than that of the sol and a boiling point higher than that of the sol liquid, and solidifying the droplets in the liquid medium to spherical particles containing no sol liquid. The sol particles may comprise one or more actinide metal oxides, e.g. urania, thoria, or a mixture thereof with one or more rare earth oxides (including yttria) or zirconia.  Sols of alumina, zirconia, and beryllia can also be used. The sol may be an aquasol, in which case a suitable immiscible liquid medium comprises a chlorinated hydrocarbon, or a mixture thereof, having a density of 1.1 to 1.3 at operating temperature and a b.pt. between 130 DEG  and 180 DEG  C.  The initial size of the droplets may be 0.1 to 1.0 mm. dia., and the droplets may contain 1 to 30% by weight solids.  The spherical particles produced may be 5 to 500 m  dia. Spherical oxide particles may be sintered alone or together with other oxide particles or with a material which reacts with the oxides during sintering, e.g. actinide metal oxide particles when sintered with carbon form actinide metal carbides. Uranium carbide is thus prepared from urania.

Title: Impact wrench
IPC: B25B21/02
Filed: 1940-07-25
Abstract: 540,239. Screwing up nuts &c. CHICAGO PNEUMATIC TOOL CO. July 25, 1940, No. 12151. Convention date, Nov. 22, 1939. [Class 83 (iii)] An impact wrench for operating nuts &c. by means of a series of hammer-like blows is constructed with a socket 76, Fig. 1, connected to a spindle 35 fitted with an impact clutch comprising anvil-like extensions 37 which are adapted to be engaged by pivoted hammer dogs 60 connected by pivot pins 61 to a squirrel-cage mounting 50, 55 adapted to be driven by the rotor shaft 30 of a rotor 31 driven by an air motor 23, mounted in a portable housing 20 fitted with a pistol-grip handle 21 and having attached to it a housing 19 for the clutch members. The dogs 60 are driven by a cam 51 splined to the shaft 30 which engages a groove in each dog and imparts momentum to the driving part of the clutch prior to the engagement of the driving and driven surfaces 67, 68, Fig. 10. These remain in driving engagement if little resistance is encountered, but in case of a frozen nut the resistance causes declutching of the driving-dogs 60 due to a slight rebound of the driving-member and the continued motion of the cam 51 acting to rotate the dog 60 counter clockwise. This action is resisted by friction and by centrifugal force and is due to constructing each dog 60 so that its centre of gravity is below the axis of its pivot 61. Cam surfaces 65 on the dogs 60 and 66 on the driven member maintain the dogs in declutched position as shown in Fig. 14, until finally the cam surfaces 65, 37 move the dogs into clutching position as shown in Fig. 12 in which position a hammer blow is about to be delivered. The wrench socket 76 is driven by a polygonal projection 74 of the spindle 35 and is fitted with a locking pin 78 which fits tightly in the projection and loosely in the socket head and is held therein by an elastic band 81. The shank 36 of the tool head is mounted in a steel bushing 39 surrounded by a resilient sleeve 40 of oil resisting synthetic rubber "Neoprene" (R.T.M.) which is formed with an annular groove 46 to permit grease inserted through an opening normally closed by a plug 45 to pass through ports to an annular groove 47 in the inner surface of the bushing 39. The dogs 60 and their mounting are symmetrical and can be inverted so as to change the driving edges to allow of longer wear.

Filed: 1968-03-13
Abstract: 1,187,944. Electrolytic fluid switches. TELEFONAKTIEBOLAGET L. M. ERICSSON. 13 March, 1968 [14 March, 1967], No. 12298/68. Heading G4P. In a fluid switching device, a channel B, containing an anode grid A connected to the positive pole of voltage source V, has a constriction F containing cathode plates K1, K2 that can be connected through a switch S to the negative pole of the source V, and outlet channels C1, C2. An electrolytic liquid flows through the channel B and through one of the outlet channels until closure of the switch S connects the anode with (say) the cathode K1, the resulting electrolytic action causing gas to form at K1 and producing a hindering pressure that ensures that the flow is through the channel C2. The flow is maintained through the channel C2 even when the switch S is disengaged. Activation of the other cathode K2 switches the flow to the channel C1. For sulphuric acid the switching can take place in about 10 milliseconds. In a modification (Fig. 2, not shown), anodes (A1), (A2) are also contained within the constriction F so that the additional gas pressure at the anodes can be utilized with a corresponding reduction in switching time. Further modifications are proposed in which anodes A3, A4 are contained in the outlet channels C1, C2, so that switching of fluid flow automatically cuts off the current; in which the switched fluid stream can be used as an electric switch by making or breaking contacts between further electrodes placed in the outlet channels; and in which there are an arbitary number of outlet channels.
