IPC: C08F8/00
Filed: 1965-09-08
Abstract: An alkylated or haloalkylated polymer having a molecular weight of 10,000-1,000,000, which is soluble in alcohols and aliphatic hydrocarbons, is prepared by heating a homopolymer derived from an acrylic ester monomer or a copolymer derived from 5-95% by weight of an acrylic ester monomer and 95-5% by weight of a non-heterocyclic monoethylenically unsaturated monomer, with an a -olefin or a fluoro- or chlorofluoro-derivative thereof, in solution in an organic solvent common to the polymer and olefin or haloolefin in the presence of 0.025-0.3 mole of an organic peroxide catalyst per mole of the olefin at a temperature of 80-200 DEG  C., the molar ratio of the olefin or haloolefin to the acrylate ester moiety equivalent being from 0.05 : 1 to 12 : 1. The polymer or copolymer is preferably derived from an acrylate of a C1-C18 alkanol or C3-C6 alkoxyalkanol. The non-heterocyclic monomer may be a vinyl ester, a methacrylate ester, an a -haloacrylate ester, a -ethylacrylic acid, vinyl isobutyl ether, acrylonitrile, methacrylonitrile, acrylamide, methacrylamide or an N-alkyl or N-aryl acrylamide. The polymers may be obtd. by polymerizing the corresponding monomer(s) in a solvent such as an alkanol, diol, diacetone alcohol, ethylene glycol monomethyl ether acetate or methylene chloride using an initiator such as an organic peroxide or azobisisobutyronitrile. The aforementioned solvents also serve as the medium for alkylation.  Peroxides for use as initiator and/or for the alkylation reaction include t-butyl perbenzoate, dibenzoyl peroxide, benzoyl hydroperoxide, t-butyl hydroperoxide, t-butyl perphthalic acid, p-chlorobenzoyl peroxide, t-butyl peracetate, di-t-butyl peroxide, cumene peroxide, di-t-amyl peroxide and lauroyl peroxide.  The alkylating agent may be any a -olefin having a molecular weight from 28 (ethylene) to 2500 (for polybutenes) and may include mixtures obtained by cracking petroleum wax; several examples are given.  Alternatively, a fluoro- or chlorofluoro-a -olefin may be used, e.g. dichlorovinylidene fluoride, chlorovinylidene fluoride, chlorotrifluoroethylene, tetrafluoroethylene or vinylidene fluoride.  The alkylated polymers are suitable for use in hair sprays, as dispersing agents in fuel oils or lubricating oils, and as fire-retardants.

Abstract: 1402307 Masted fork lift attachment for cranes F D WELCH 17 Aug 1972 [26 Aug 1971 10 May 1972] 38489/72 Heading B8H A masted fork lift attachment is securable to the end of a crane boom for operation by the lift cable thereof and has a levelling arrangement whereby the mast may be adjusted to extend vertically for any inclination of the boom. The attachment comprises a frame 41 with a suspension pin 23 detachably received in a recess 77 in two plates 75 fixed to the end of the boom. The pin is locked in the recess by a rotatable latch 80 which can be locked by a spring biased catch 81. A locking pin 84 actuable by a lever 85 engages in recesses in the plates 75 to lock the frame 41 against rotation relative to the boom. A pin 73, mounted on the frame 41, pivotally supports a telescopic mast structure 30 comprising a first section 70 and a second section 89 along which a fork carriage 36 is movable under the action of the lift cable secured thereto. A latching arrangement Figs. 9-11 (not shown) is actuable by the fork carriage as it moves along the mast to suspend the second section 89 from the first section in the retracted condition of the mast and to suspend the second section from the carriage in the extended state of the mast. A pair of racks 53, with a greater lateral spacing than the frame 41, are pivoted at one end to the first section of the mast remote from its connection to the frame and is engaged by a carriage 64 with two guide rollers 58, 60 to engage respective surfaces 56, 59 on the rack, and a pinion 49 driven by a motor 39 mounted on the frame. The motor is remotely controlled to retract or extend the racks and thus pivot the mast about the frame to keep the mast vertical for different elevations of the boom. A pendulum actuated indicator 153 provides the crane operator with information regarding the inclination of the mast. In an alternative embodiment, Fig. 21 (not shown), the racks are replaced by hydraulic rams acting between the frame and the mast structure 30. In operation the lift cable is passed around a pulley zone mounted on the frame 41 and the hook is secured to the boom. Retraction of the cable will then raise the attachment from the ground &c. until the pins 23 and 84 can be locked in position. The hook is then released from the boom and engages with the fork carriage for operation of the attachment.

Title: Glazed siliceous catalyst and process utilizing said catalyst
IPC: B01J33/00
Filed: 1958-12-09
Abstract: A catalyst comprises particles (e.g. spherical rod-like or crushed aggregate) of siliceous material having a microporous core (preferably at least 40% SiO2) which material may be (a) a synthetic silica cracking catalyst comprising at least one other metallic oxide such as Al2O3, MgO or ZrO2 (e.g. 70-90% SiO2, 10-30% Al2O3), or (b) an activated or natural clay of the bentonite halloyrite and kaolin types, the surface of said particles being partially covered with an adherent, substantially attrition-resistant glaze comprised of silica and one or more alkali-metal, alkaline-earth metal or boron compounds.  Numerous Na, K, Li, Cs, Rb, Be, Mg, Ca, Sr, Ba and B derivatives are listed, but CaCO3 (100%), BaCO3 (100%) and a composition of 1-25% MgO, 30-75% CaCO3 and 25-50% Ca3(PO4)2 (totalling 100% are preferred.  The preparative method specified is to contact the particles with 0.01-2% of all glazing substance above 1000 DEG F. at a sufficiently high temperature to induce fusion between the surface of the particle and the said substance. Preferably, the particles are contacted with a liquid hydrocarbon and said substance (the latter may be dispersed in the former or may be applied as a dry powder or aqueous slurry), the hydrocarbon subsequently giving rise to a carbonaceous deposit which is burned so as to allow formation of the glaze under the conditions stated above. The catalyst may be used in a moving-bed type petroleum cracking process which embodies conventional regeneration, it being preferred that the said glazing substance should be supplied continuously or intermittently while the cracking unit operates, to replace the glaze on the surface of the particles.

The drilling operation is continued with the relevant units being pivoted, the programme being fed into a control unit, 52 in the form of a punched tape.
Patent GB-1211998-A (GB)
Title: Circuit arrangement for the electronic control of actuating members for machine controls
IPC: G05B19/08
Filed: 1969-08-12
Abstract: 1,211,998. Recoding circuits. KRAUSS-MAFFEI A.G. 12 Aug., 1969 [14 Aug., 1968], No.40306/69. Heading G4H. A switching arrangement for control elements which initiate or terminate operation steps of a machine, the elements 18, 19 &c. are controlled by actuating transistor units 15 which are in turn controlled by combinations of switches 6 acting through transistor amplifiers 11 and the electrical connections between the switches and the transistor amplifiers and between the amplifiers and the transistor units 15, and the transistor units themselves are supported on a single plate. The connections between the switches 6 and the transistor amplifiers 11 comprise vertical and horizontal leads printed on opposite sides of the board. Resistors connecting row and column leads are soldered to the leads through holes in the plate. The amplifiers 11 are assembled in groups of four, one for each row lead 4. Resistor connections 13 are made from the row leads 4 in a second conversion matrix 2 to appropriate column leads 5 to actuate selected ones of four bi-stable multivibrators 12. The outputs of these are connected in a third conversion matrix 3, together with some of the column leads 5 of matrix 2, to energize certain inputs to transistor units 15 and thereby operate corresponding power transistors 16 connected by wires 17 to the control elements 18, 19. The transistor units 15 each comprise two similar transistor stages 36, 36a, Fig. 3, providing a signal large enough to control a power transistor 16. The switch 33 is turned on by a signal on lead 5b and off by a signal on lead 5a which, through transistor 35, nullifies the signal on lead 5b. If a short-circuit fault appears on the output, the potential of the collector of the corresponding power transistor rises. Diodes connect all these points to a bi-stable transistor pair which switches in response to a fault and applies a signal to the inputs 5a of all the transistor units, thereby protecting all the power transistors against overload.

Title: Improvements in or relating to direct-voltage monitoring circuits
IPC: G01F23/00
Filed: 1959-11-27
Abstract: 899,104. Transistor oscillator and switching circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 27, 1959 [Dec. 2, 1958], No. 40415/59. Class 40(6) A direct voltage monitoring circuit comprises a feed back oscillator including an amplifying element which, when the direct voltage is below a first level is non-conducting so that the oscillator is inoperative but which, when the direct voltage is above that level, becomes conductive so that the circuit oscillates, the amplifying element having a load resistor of such magnitude that when the direct voltage exceeds a second level, saturation takes place so that oscillation ceases. Fig. I shows a relaxation oscillator comprising a first transistor 1 coupled via a transformer 10 to a second transistor 2 having its output fed back regeneratively to the input of transistor I through a circuit 20, 21, 23. Transistor 1 is biased at its emitter by a voltage derived from a "Zener" diode 4 through a resistor 14 so that when the voltage of a D.C. signal Vi is less than the bias the transistor is non- conductive the circuit does not oscillate. If however the voltage Vi exceeds the bias voltage, transistor 1 conducts and oscillation commences. The output from the oscillator is rectified by a voltage doubler circuit 20, 18, 21, 23 feeding the base of transistor 2 so that the oscillation causes the D.C. current through the transistor to increase and so operate an alarm relay 17, the increase being assisted by the fact that the resistance of diode 21 in the biasing circuit 19, 21 decreases. If the voltage Vi exceeds a certain level the voltage drop across a resistor 12 in the collector circuit of transistor 1 causes the transistor to saturate so that its gain decreases and oscillation ceases. This causes the relay to release. In an alternative circuit (Fig. 2 not shown) the oscillator is of a cathode coupled multi-vibrator type, an output from the oscillator being derived through a transformer and applied to a transistor amplifier to operate the relay. Rectifiers are provided to damp ringing oscillations in the transformer and the relay winding and a capacitor is connected across the transistor of the amplifier so that the relay does not chatter. In this circuit a D.C. output may also be obtained from the emitter of the amplifier transistor. In both circuits stabilization may be effected by using resistors 14 or 5 of negative or positive temperature coefficient respectively.
