Specified alkyl groups are methyl, ethyl and isopropyl, while the aryl group may be a phenyl group.  Suitable organoaluminium compounds are trimethyl, triethyl, triisobutyl and trihexyl aluminium and the transition metal compound may be of Ti, V, Cr, Mn, Co or Fe. The polymers obtained have regular syndiotactic structure.  In the examples, all of which are carried out under nitrogen, TiCl4 and AlEt3, tri-isobutyl aluminium, or trihexyl aluminium, are dissolved in toluene and methyl methacrylate is polymerized in the solution at -78 DEG  C.  Ethyl, isopropyl and cyclohexyl methacrylates are similarly polymerized, using AlEt3 as the aluminium compound.  In Example 5 tetrahydrofuran is present in the toluene during polymerization of methyl methacrylate, again employing AlEt3.

Title: Circuit arrangements for generating current of saw-tooth wave-form
Inventor: WALKER ALEC HERVEY BENNETT
IPC: H03K4/83
Filed: 1962-06-08
Abstract: 1,000,692. Sawtooth circuits. WESTING- HOUSE ELECTRIC CORPORATION. June 8, 1962, No. 22281/62. Heading H3T. [Also in Division H2] A sawtooth current generator comprises at least one semi-conductor controlled rectifier TS connected in series with the parallel combination of an inductor L1 and a resonating capacitor C3 and having a diode D connected in parallel opposition. The controlled rectifier TS is preferably of the type in which the anode current can be interrupted by a control pulse of reverse polarity and is arranged to be conductive only during the latter part of each sweep. As described, capacitor C1 is initially charged via resistor R and discharged via the controlled rectifier TS and the line deflection coils L1 of a television receiver. The diode D recovers energy stored in the coils L1 at the beginning of each sweep. The current in TS is interrupted at the end of each sweep by a gate pulse PD (Fig. 4) which is differentiated by capacitor C2 and the effect of stored carriers, so as to provide a gate current b. A series resonant circuit L2, C4 tuned to an even harmonic of the flyback frequency, is shockexcited during each flyback period and arranged to execute 6À25 or 7À25 cycles of oscillation during each sweep. This oscillation delays the build-up of anode voltage during the flyback thus facilitating the interruption of current by pulse PD. L2, C4 also reduce the recovery period. The current may commutate several times between the devices TS and D during the sweep, the respective current waveforms being shown at c, d. Resistor R protects the circuit against failure of pulses PD or short circuit across the secondary of transformer T. The inductor L2 may be part of an e.h.t. transformer T, preferably tuned to the second harmonic of the flyback frequency. The output of transformer T is rectified to produce e.h.t. supply for a cathode-ray tube. In Fig. 1 (not shown) transformer T is connected in parallel with the deflection coils L1. Specifications 906,524 and 983,266 are referred to.

Title: Tank washing apparatus
IPC: B05B3/00
Filed: 1959-06-30
Abstract: 873,589. Spraying apparatus. BUTTERWORTH SYSTEM Inc. June 30, 1959 [Aug. 1, 1958], No. 22408/59. Class 69 (3). A tank cleaning device comprises a hollow nozzle structure 4 rotated by jet reaction from nozzles 103 and 104 (not shown), about a horizontal tubular part 47 of a nozzle structure support 2. The nozzle structure is associated with a clutch drive operated by the pressure of liquid fed through the device whereby gearing within a gear case 1 assists in driving the support 2 about its vertical axes. The gear case also contains a liquid lubricant and an adjustable governor pump which draws in and pumps out lubricant and acts as a brake to control the speed of rotation of the device. The nozzle structure is rotatably attached to a liquid diffuser 48 attached by vanes to the part 47, and the gear case is bolted to the support 2 which, in turn, is bolted to a cap 81 which rotates about a non-rotary tube 71. Hose coupling elements 91, 92 are loosely held on to the tube 71 by an annulus 96 and, in operation, teeth 99 on the lower face of the annulus engage corresponding notches in a shoulder of the element 91 to prevent relative rotation between the tube 71 and hose coupling. The clutch drive from the nozzle structure includes a clutch plate 118 which has slight axial but non- rotary movement relative the nozzle structure, and its outer face has tooth and notch portions 119, 120 which are forced by liquid pressure acting through passages 116 and a rubber ring 117 against corresponding teeth and notches in an annular ring gear 121 rotatably mounted on the part 47. Thus the gear 121 drives, through a gear 29, a shaft 25, and this drives through gearing 28, 33 and shafts 31, 62 a gear 63 which meshes with a ring gear 76 fixed to the non- rotary tube 71. In order to prevent overlap of the jet impingement paths at each revolution of the device about its vertical axis, the number of teeth on the ring gears 121 and 76 differ slightly. The governor pump used may be any positive displacement pump such as a gear or diaphragm type. In the Figures a pump of the reciprocating piston type is provided and driven via gearing from the shaft 25. It consists of a cylinder block 36 pivoted to a shaft 21, and receiving a piston head 39 attached to a connecting rod 40 driven by a crank 24a. The crank is connected to a shaft 24 driven via gearing 30, 35 from the shaft 25. Ports 36b, 36c in the cylinder head and leading to the gear case interior are adjustable to vary the braking effect on the drive. An embodiment in which a vane pump is used is also described.

Abstract: 845,622. Television. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 15, 1958 [July 15, l957], No. 22636/58. Class 40(3). [Also in Group XL(a)] A device suitable for scanning a panel consisting of two or more intercoupled groups of conductors, a l  - a j  - a n  and b l  - b n  Fig. 1, the device when in use being connected as at 5 to one group or part of one group, comprises a first system having a delay circuit 2, Fig. 2 being connected via tappings to unidirectionally conductive elements 15 and further elements 16 capable of emitting radiation or extinguishing under the action of applied voltages, in series, and a second system having photo-conductive elements 18 electrically coupled at 5 to the conductors of group b, the two systems being substantially electrically separated and being located relative to one another so that the radiation from the 'elements 16 acts upon the associated photo-conductive elements 18, whilst the ends of the series combinations 15, 16 not connected to the tappings are connected to a source 7 of pulsatory voltage V p 2 and that each of the elements 18 is energized by a source 8 of voltage V#. The device may have a layered construction as shown in Fig. 2 with island electrodes 17, and radiation pervious electrodes 3, 3<SP>1</SP> together with an insulating layer 26 opaque except at points lying between the elements 16 and the associated elements 18. A resistance layer 19 may be provided between the layer 18 and the electrode 4 connected to the voltage source 8. In operation, the information signal e.g. a television video signal is supplied to the delay circuit so that it takes one line period to traverse the length 20-21. At the end of a line period the electrode 3 is pulsed so that layer 15 conducts and layer 16 emits radiation of an intensity at each point proportional to the video signal. This results in a corresponding decrease in resistance at associated points in the photo-conductive layer 18, which resistance changes vary the alternating voltage applied on b group conductors to the electroluminescent picture panel. The corresponding line from the group a conductors is earthed via switch 23 during its line period, the remaining a conductors being subjected to a positive potential Va. The panel thereby luminesces in accordance with the applied video signal at the appropriate crossing point between the a and b conductors. Arrangements for interlacing and multicolour output are described.
