Title: Improvements in or relating to shotgun shell casings
IPC: F42B5/30
Filed: 1956-12-19
Abstract: A cartridge case moulded of polyethylene such as that produced by the processes described in Belgian Specifications 533,362, 534,792 and 534,888.  Instead of using a moulding process to form the cartridge, the polyethylene may be produced in sheet form from which tubes are made as with paper cartridge cases.  The polyethylene used has a reduced specific viscosity of at least 1.2 and preferably 2, the reduced specific viscosity being the specific viscosity corrected to zero shear gradient and divided by the concentration of the solution in grams per 100 millilitres, measured at 135 DEG  C. for a solution in decalin containing 0.1 grams of the polymer in 100 millilitres of solution.  The catalyst used to produce the polyethylene may be formed by mixing an organometallic compound of a metal selected from the alkali metals, alkaline earth metals, zinc, earth metals and rare earth metals with a compound of a metal selected from the metals of Group IVB, VB or VIB of the Periodic Table.  This catalyst may be an organo-aluminium compound mixed with a titanium compound.

Title: Improved automatic controller for continuous processes
IPC: G05D7/06
Filed: 1961-11-06
Abstract: 922,689. Automatic control. INDUSTRIAL NUCLEONICS CORPORATION. Nov. 6, 1961 [Nov. 7, 1960], No. 39723/61. Class 38 (4). In a continuous processing plant, e.g. cigarette rod-forming, ore crushing, or calender. ing, in which a reservoir of material is maintained between input and output, means responsive to deviation in the quantity of material in the reservoir causes a step change of fixed amount in the input rate which, after a time interval, returns to substantially its previous value. Thus, short-term deviations are corrected without greatly affecting the average flow. As shown in Fig. 2, deviation at time T 1  from a mean M 0  in the reservoir quantity results in a change (increase or decrease) in input from Vo to Vh. After a time # 2 , the input is returned to a level only slightly different from Vo. No. further change can occur until a time T 2  is reached when, if the correction was insufficient, the cycle is repeated. The time intervals #1 ... #4 are determined by clock timers and thyratron circuits (Fig. 4, not shown), and a first such circuit ensures that the deviation exists for a minimum time before correction is applied. The intervals may all be fixed or #2 only may be made dependent upon the amount of deviation, by arranging for a resistive bridge to be progressively unbalanced to charge a timing capacitor (Fig. 5, not shown). When applied to a cigarette-forming machine, Fig. 3, the reservoir comprises a carded drum 68 carrying the excess tobacco removed from a stream by a knife 58, and the detector 72 comprises a feeler operating either a two-way microswitch or a potentiometer in the bridge circuit of Fig. 5. The controlling pulse . operates a servomotor 78 to adjust a variable speed-gear 80 driving a tobacco distributer 52. In an ore-crushing plant (Fig. 6, not shown), the reservoir is a return stream of oversize particles rejected by a classifier placed at the output of a ball mill. Excess of such particles indicates that the mill is overloaded, so the ore supply is adjusted according to the invention. In a calendering process (Fig. 7, not shown), a sheet of masticated plastic and adhesive substance builds up into a "-pencil bank " before a pair of reducing rollers, and the size.of this bank is detected by a photo-electric cell arrangement whose signals are used to control, in the manner of the invention, the spacing of a pair of knives which determine the width of the strip reaching the rolls.

Title: Improvements in or relating to circuit arrangements for converting a pal system colour television signal into an ntsc system signal and conversely
IPC: H04N11/20
Filed: 1965-09-17
Abstract: 1,070,998. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 17, 1965 [Sept. 19, 1964], No. 39756/65. Heading H4F. P.A.L. signals are converted to N.T.S.C' signals in a circuit arrangement in which the colour subcarrier wave is applied to a line sequential switch 1 to cause alternate lines to be separated at output terminals 3 and 4, terminal 3 being connected directly to an adder 7 and terminal 4 being connected via a mixer 10 which is also supplied with a local oscillation of twice subcarrier frequency from a source 15. The difference frequency component from the mixer at the original subcarrier frequency has the modulation sequence reversed and is selected by a filter and applied to adder 7 over connection 11. The adder output thus has the same modulation sequence on all lines and constitutes an N.T.S.C. subcarrier. Where it is desired to eliminate subcarrier phase errors by electrically adding successive lines a one-lineduration delay line 8 by-passed by an impedance 8<SP>1</SP> of equivalent loss is included in the signal channel. If an N.T.S.C. signal is applied at the input, the circuit functions to produce a P.A.L. signal. Delay line 8 and impedance 81 are omitted in such case. An N.T.S.C. signal may be passed through the circuit without modification by interrupting the operation of switch 1. Interruption of the switch operation may be controlled automatically by using the absence of a characteristic pulse signal from the P.A.L. signal. Circuit 12 is provided for combining the subcarrier with the luminance signal and processing the composite signal for subsequent use. Where the arrangement is included in a receiver the processing may involve detection of the subcarrier. For this purpose a reference signal of subcarrier frequency is supplied from source 15. Where the arrangement is included in a relay station the processing may involve modulating the composite signal on a carrier for onward transmission. Circuit 12 supplies a synchronizing " burst " signal for control of source 15. Detailed valve and transistor circuits suitable for mixer 10 are described with reference to Figs. 2 and 3 (not shown). In a modified arrangement, Fig. 4 (not shown), the output from terminal 3 from switch 1 is also passed through the mixer 10 so as to equalize the gains in the two paths to adder 7. A second mixer which receives the signal from terminal 2 is also connected to the adderfunctions to cancel the modulation product from the first mixer whereby only the original signal from terminal 3 appears in the adder amplified by the same amount as the modulation product of the signal from terminal 4. Switch 1 is controlled by a waveform 6 having positive and negative excursions of unequal durations T 1  and T 2  so as to prevent the synchronizing " burst " from being passed through mixer 10 where it would be subjected to an undesired phase shift.
