Abstract: 1225932 Electric watches TIMEX CORP 26 Aug 1969 [20 Sept 1968] 42534/69  Headings G4D D7X D6Y D6C1 and D6C2 In an electric watch including a high frequency electrical oscillator 30, a frequency divider 35, an inhibit circuit and time display means, pulses from the divider are transmitted to the inhibit circuit to control the effective frequency of the oscillator. A battery 18 is connected to a circuit 20, shown in detail in Fig. 2, which pulses a motor 21 such as an electromagnetic reciprocating solenoid. The motor reciprocates a pawl 22 at a frequency of 1 Hz. thus rotating an index wheel 23 and hands 15-17 via gears 24, 25 of a gear train. Alternatively the time may be displayed by lamps or liquid crystal devices. The oscillator 30, which is a Piezo-electric crystal, is manufactured to have a frequency a few Hz. above the desired effective frequency which when divided by the divider 35 supplies an output at 39 at a frequency of 1 Hz. to the motor 21. To inhibit the excess pulses from the oscillator a NAND element 32 and a multi-vibrator 37, the time base of which is adjustable by a potentiometer 38, are provided. Changes in frequency of the oscillator due to age or temperature changes are compensated by an element 40 which may be a thermistor. The potentiometer 38 is adjusted to set the time period of the multi-vibrator to a value sufficient to inhibit the NAND element for a period such that the excess pulses are inhibited. Two modifications of the circuit 20 are also described.

Abstract: 1,230,088. Testing diodes. PLESSEY CO. Ltd. Aug.28, 1968 [Sept.22, 1967], No.43257/67. Heading G1U. Variable-capacitance semi-conductor diodes are tested to determine whether the constants defining their voltage-capacitance relationship fall within prescribed limits by measuring their capacitance at one voltage and then at two further voltages, and determining whether the second and third measurements fall within limits which are dependent on the result of the first measurement. A device for indicating the limits for the second and third measurements comprises three logarithmic scales, Fig. 1a, one for each measurement, and a cursor having the marks shown in Fig. 1b. It is shown that if the diode constants are satisfactory, when the datum mask AA is aligned with the first measurement as indicated on the middle scale, the second and third measurements will lie within the limits shown by marks B 1  B 2 , C 1  C 2  respectively, and all three measurements will lie approximately on a straight line, as 1 rather than 2.

Abstract: 1,230,615. Colour television. FERNSEH G.m.b.H. 18 July, 1968 [27 July, 1967], No. 34275/68. Heading H4F. In an arrangement for the regeneration of the colour burst in a colour television signal, in particular a PAL colour system having a "swing- ing" burst, the colour burst is rectified in a rectifier 11 to which the composite television signal at input 1 is fed only during the burst interval due to a gate 12 triggered by a pulse generated by transformer 13 from a synchronizing signal. The mean value of the rectified voltage is extracted by a filter 14 e.g. a capacitor, and if necessary the pulse is reformed in a pulse generator 15. This pulse and a pulse derived from the synchronizing signal in a generator 16 are fed to an AND gate 17 which delivers an output pulse only when both inputs are present simultaneously. This output pulse, which may be shaped 18, gates 19 a continuous colour carrier oscillation from a colour carrier generator synchronized with the colour burst of the original television signal, to produce a new colour burst which is added 3 to the original television signal (which may be delayed 6) after the original colour burst has been removed 4. This arrangement ensures that a new colour burst is only added in periods when a colour burst was present in the original television signal, i.e. it is not added during the field synchronizing interval for a PAL colour system.

[Also in Division H3] In a ceramic memory device comprising a ferroelectric memory sheet with electrodes on opposed major surfaces which is read out non- destructively by energizing a piezo-electric or magnetostrictive drive sheet so as to impart mechanical stress to the memory sheet, a separate drive sheet is mechanically coupled to each of the major surfaces of the memory sheet. As shown in Fig. 5, a single bit memory device comprises ferroelectric memory sheets 34, 34<SP>1</SP> and drive sheets 32, 32<SP>1</SP> with interposed electrodes 42, 42<SP>1</SP>, 44, and external electrodes 40, 40<SP>1</SP>. An operating circuit is included in which with switches S-1, S-2, S-3 in the positions shown, an interrogation pulse Vin applied to electrodes 40, 42 and 40<SP>1</SP>, 421 produces mechanical stress which temporarily changes the capacitance of storage sheets 34, 34<SP>1</SP>. Consequently an output pulse Vo is developed between ground and terminal OUT the polarity of which is indicative of a stored binary value. Using switch S-2 and switch S-3 in one of its other two positions, a remanent state in one or the other sense is established in the ferroelectric memory sheets 34, 34<SP>1</SP>. Switch S-2, in conjunction with switch S-1, is also used to establish an initial polarization in the drive sheets 32, 32<SP>1</SP>. The remaining embodiments are disclosed in Specification 1,233,911 from which the present Specification was divided.

To facilitate the application of flexible printing plates of, for example, plastics material, to plate cylinders, and to aid the registration of the individual printing plates in multicolour printing, each plate P is applied to a curved support saddle S before use and the.saddle; with the plate on it, is clamped on to a plate cylinder. Plate P is placed on table 3. Slidable clamps 34, 50 hold the plate on the table 3, and make it possible to move it into a correctly registered position. Then table 3 is moved into the position shown in dashed lines, so that the plate contacts saddle S, which is temporarily mounted on cylinder 4. Rotation of cylinder 4 draws plate P from table 3 and roller 16 presses it firmly against saddle S, where it is fastened by an adhesive. The saddle may then be transferred to a plate cylinder, where it is preferably secured by clamps identical to those which held it to cylinder 4. Alternatively table 3 may feed the plate directly to a saddle mounted on a plate cylinder.

Normally 0À1 to 1,000, preferably 0À1 to 2À0, parts by weight of isocyanate may be employed for 100 parts of alkylene oxide, but even traces of isocyanate are stated to effect an increase in the degree of polymerization of the alkylene oxide. When diisocyanates are employed only one isocyanate usually reacts, the other remaining available for subsequent reaction with active hydrogencontaining compounds such as polyether, polyester and polybutadiene diols, and polyvinyl alcohol. The effectiveness of the catalysts may be enhanced by treatment with alcohols. In examples ethylene oxide, propylene oxide and mixtures of ethylene oxide with epichlorohydrin are copolymerized with phenyl isocyanate, ethyl isocyanate, 2,4-tolylene diisocyanate or hexamethylene diisocyanate using catalysts prepared from dibutyl tin oxide, dibutyl tin dilaurate, tin tetrachloride, triisobutyl aluminium, aluminium isopropoxide, aluminium chloride, zirconium chloride, zirconium oxychloride, tetraphenyl lead, boric acid, trimethylboron, ethyl orthosilicate and titanium tetrachloride on the one hand and orthophosphoric acid, metaphosphoric acid, tributyl phosphate, phosphorus oxychloride and aqueous diammonium phosphate on the other; in some cases further modified with n-butanol. Other suitable alkylene oxides are butene, isobutylene, trifluoromethylethylene, cyclohexene, styrene and butadiene oxides, epibromhydrin, and methylglycidyl, phenylglycidyl and allylglycidyl ethers. In Example 26 a polymer formed from ethylene oxide, epichlorohydrin and 2,4-tolylene diisocyanate is further reacted with polybutadiene diol, which combines with free isocyanate groups, to provide a rubbery copolymer which is subsequently compounded and subjected to conventional vulcanization.
