Abstract: 1,159,552. Polymerizable paint binder compositions. FORD MOTOR CO. Ltd. 9 Aug., 1966 [13 Aug., 1965], No. 5426/69. Divided out of 1,159,551. Headings C3P and C3T. Paint binders polymerizable by means of ionizing radiation comprise a film-forming solution in a flow-inducing solvent of (a) a vinylunsaturated binder component consisting essentially of an addition product of a diisocyanate and a C 5 -C 12  monohydroxy acrylic monomer, the said addition product having a molecular weight below 900, and (b) an organic resin having a molecular weight in excess of 1000 and containing 0À5-3 olefinic unsaturation units per 1000 of molecular weight, the resin (b) and binder component (a) being copolymerizable by ionizing radiation. The film-forming solution may be pigmented, e.g. with TiO 2 . The flow-inducing solvent may be a vinyl monomer or monomers, e.g. methyl methacrylate and/or styrene. In examples the binder component is an adduct of tolylene diisocyanate and 2-hydroxy ethyl methacrylate and the organic resin is (i) a silicone-modified polyester obtained by reacting nepoentyl glycol with a methoxylated partial hydrolysate of monophenyl and phenylmethyl silanes consisting essentially of dimethyltriphenyltrimethoxytrisiloxane and then further reacting with maleic anhydride, tetrahydrophthalic anhydride, dibutyl tin oxide and xylene; (ii) a silicone-modified polyester similar to (i) but wherein the siloxane used is a hydroxyfunctional, cyclic polysiloxane; (iii) a polyester derived from maleic anhydride, tetrahydrophthalic anhydride and neopentyl glycol; (iv) a methyl methacrylate/ethyl acrylate/glycidyl methacrylate copolymer modified by reaction with methacrylic acid.

Abstract: 792,798. Turf-piercing machines. ELLIS, W. May 25, 1955 [Feb 26, 1954], No. 5664/54. Class 6(1). A turf aerating device comprises a wheeled chassis having mounted thereon a vertically reciprocating spike-carrying plate, together with driving means which serve both to reciprocate the plate and to propel the device forwards intermittently. The spike-carrying plate F is mounted between two sliders M<SP>1</SP> which are made to reciprocate in vertical sliders M by means of connecting rods G mounted on pivots on crank wheels E<SP>1</SP> at each end of a motor driven shaft E, the spikes F<SP>1</SP> reciprocating through holes in a stationary plate T which serves to remove any soil adhering to the spikes. A cam L mounted midway along the shaft E co-operates with a ratchet arm H pivotally mounted on the front axle C of the device in such a manner that as the spikes leave the ground, the cam lifts the ratchet arm H and causes a lug thereon to engage the teeth of a ratchet pinion R, thus rotating the wheels A, the cam L being disengaged from the ratchet arm H, thus arresting the forward motion of the device, when the spikes are about to re-enter the ground. A brake may be incorporated to ensure that the device remains stationary when the spikes are in the ground.

Abstract: 230,114. Akt.-Ges. Brown, Boveri, et Cie. March 3, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Balancing moving parts; regulating; motor power plant.-The steam space of the balancing piston of an extraction turbine is connected with the steam space in front of the low-pressure blading. A pipe L connects the pressure side D of the dummy piston A with the steam space N of the low-pressure section which receives steam from the extraction chamber E through a transfer valve. A packing piston K is situated between the piston and the chamber E. In the construction shown in Fig. 2 the extraction stage E is supplied in parallel with a stage H which is connected with a low-pressure stage N by a conduit U by-passing the stage E, and in this case the dummy piston is open to the pressure in the stage H. By the invention leakage past the dummy piston is reduced with decreasing load on the turbine although the extraction pressure is constant.

[Also in Group XXXVI] In an arrangement for measuring the frequency of an input signal comprising an integrating network arranged to produce a D.C. output voltage proportional to the frequency, a valve voltmeter having a range adjusting switch is provided for measuring over a series of contiguous non- overlapping ranges. An electronic tachometer, Fig. 1, including such a frequency measuring arrangement comprises a signal pick-off unit 10, a preamplifier 11, a pulse shaper 12, a monostable flip-flop 13 having a recovery time less than the time interval between the trigger pulses at the maximum pulse repetition frequency to be catered for, and a valve voltmeter 14 incorporating a meter protection stage 15 the integrating network being included in the output of the flip-flop. Preamplifier V 1 , V 2 , Fig. 2, has terminals 1 and 2 for dealing with sinusoidal or square waves respectively according to the type of pick-off. Valve V 2  is maintained in a quiescent state with its anode voltage lower than the striking voltage of neon tube 17, and a negative pulse on its grid produces across resistor 20 a voltage having a rapid rise time. Differentiating network 21, 22 produces sharp alternately positive going and negative going pulses, and the positive pulses selected by rectifier 23, Fig. 3, trigger flipflop V 3 , V 4 , to produce a square wave voltage across anode load 26, the voltage excursions being maintained constant by neon tube N1. The potential across condenser 39 of the integrating network is applied to the grid of valve V5 and gives an indication in meter 16, the range being determined by the potential on the grid of valve V6 from a potentiometer 27. Diode 29 protects the meter if the speed is too low, and parallel connected valves V7, V8, having a relay 30 between their anodes short circuits the meter and illuminates an "increase range" warning lamp if the speed is too high. The apparatus may be associated with a flow meter. Specification 752,496 is referred to.
