Abstract: 1,268,872. Digital to digital converter. GENERAL ELECTRIC CO. Ltd. 19 June, 1970 [19 March, 1969], No. 14468/69. Heading G4H. In a coding system in which position is indicated by which of a number of different ranges of position register with a detector head, so that the total range of position of the code disc can be resolved into a number of sub-ranges, means are provided for electrically biasing the signals representative of the position, so that the effective number of sub-ranges is altered. The position detecting system is of the type described in U.K. Specification 863,027 in which the coupling between a number of windings occupying various position ranges and a main winding is enhanced at a given position by means of a ferromagnetic core. The position of the encoder disc is initially represented in gray code indicated at the top of Fig. 1, this is converted into "gillam code" which is a monophilic code whose first four digits indicate which out of ten positions the disc occupies and whose subsequent digits coincide with gray code. The conversion between gray code and gillam code is achieved in the following manner:- (a) The first digit of the gillam code is derived by adding the first digit signal of the gray code to 1À2 x the second digit signal of the gray code, (b) The second digit of the gillam code, C2 is produced by biasing the 0-position upward to position A for the digit 1 signal of the gray code, (c) The third digit of the gillam code is provided by biasing the 0 position of the digit 2 of the gray code down to level B, (d) The fourth digit of the gillam code coincides with that of the third digit of the gray code. The code converter may be employed in a meter for measuring height in which a coarse and a fine scale, which are geared together are used the most significant bit of the fine scale being made to coincide with the least significant bit of the coarse scale to prevent errors caused by synchronization between the two scales.

Abstract: 344,718. Wireless transmitting systems. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. May 12, 1930, No. 14592. Convention date, Oct. 25, 1929. [Class 40 (v).] In a modulating system employing a choke in the aerial circuit and a choke in a compensating circuit, the two chokes Dr1 and Dr2, Figs. 2 and 3, are arranged in series in the anode circuit of a valve R3 supplied with the modulating currents in such a way that their preliminary magnetizations are in opposite directions and are altered in the opposite sense by fluctuations in the anode current. In one arrangement, Fig. 2, the steady anode current from battery B passes through the chokes, and choke Dr2 is given a preliminary magnetization of opposite sign to that of choke Dr1 by means of an auxiliary battery H through a low-frequency choke N1. In a modification, Fig. 3, the steady anode current passes only through choke Dr1, the d.c. circuit being completed through choke N1 and the anode battery B, which also magnetizes the choke Dr2 through a potential divider P and series resistance R, while a capacity C is connected between the choke and the valve cathode.

Title: Shearing line for edge-trimming and cutting metal sheets and plates
Inventor: GREIS KARL
IPC: B23D33/00
Filed: 1969-03-20
Abstract: 1,261,574. Shearing. MOELLER & NEUMANN G.m.b.H. 20 March, 1969 [20 March, 1968], No. 14650/69. Heading B3W. A shearing line comprises opposed edge trimming shears D1, D2 followed so closely by cross cut-shears T, which comprise a curved blade making a rolling cut, that the sheets are cut while still gripped by intermittently operating feed rollers 4, 6, 8 which clamp the sheets during the cross cut, which derive their stepwise drive from the continuous drive of the edge trimming shears and the feed step of which preceding a cross cut can be shortened independently of that drive e.g. for making a front crop cut and for varying the last or last two feed steps of a sheet to make the rear crop length sufficient for the cross cut blades to operate effectively. The rollers are normally driven by a cam wheel 40 mounted on the crank-shaft of the edge trimming shears closing a switch 41 controlling the motors V m  driving the rollers. The switch opens automatically under spring pressure. The operation of the rollers can be overridden for the front crop cut by means of a push-button 48 which isolates the motors V m  regardless of the cam position and actuates the motors T m  of the cross out shear. The second cut is made when a predetermined length of sheet has passed through the cross cut shear, by means of a lengthmeasuring roller 10 connected to the control circuit by means of a pick up 58 and a comparator 60. A preliminary switching device 80 ensures that the pick-up transmits signals immediately the front crop cut is made. A signal from the comparators shortly before the nominal/actual value comparison is zero slows down the motor V m  gradually. A similar comparison is used to reduce the final feed step when the desired sheet length is not an aliquot multiple of the feed step, i.e. the distance corresponding to one revolution of cam wheel 40. If the desired sheet length is only slightly more than an aliquot multiple of the feed step the last two feed steps are reduced. A transverse scrap cutting blade (not shown) is mounted at one end of each trimming blade. The rolling cut of the cross cut shears T is produced by out-ofphase cranks (26), (28), Fig. 3 (not shown). The sheets are supported by rollways which, at least within the cross cut shears T, have free-running rollers and are aligned for the shear T by edge guide rollers 16. A conventional ejector 12 is provided.
