Filed: 1974-07-03
Abstract: 1470460 Keyboard data entry AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 3 July 1974 [3 July 1973] 29474/74 Heading G4A Instructions which define the format of data to be entered on a keyboard, Fig. 2b, are stored in a memory M1 and provide as inputs to a set of operators OP, Fig. 2a, the number n of blank codes to fill the upper decimal digit positions of an output buffer memory M2, the number f of positions following the decimal point and a bit ICD for enabling the operation of a decimal denomination selector key TCD, Fig. 2b. The operators OP derive various parameters which further define the format of the entry, and as the entry proceeds, selectively set and reset bistables BS, Fig. 2a, for enabling/disabling the various keys on the keyboard in the proper sequence to avoid erroneous entry of data. With a new instruction being read out from M1, the system is generally reset, then operator PEM derives the parameter #f representing the maximum length of all data in an entry while a generator ECAV supplies n blank codes to the first n positions of buffer M2. Bi-stable CD is set to enable the denomination selector keys TCD, operator CDD checks that the calculated value f does not exceed a predetermined maximum d max , and an operator PtD determines the position of the decimal point. The equipment is then ready to accept data entered on the keyboard and is in a condition to provide an alarm output if, during the sequence of entries, the wrong type of key is operated or if the number of digits entered does not conform to the specified format. Data entry.-A key TCD is used to select the highest denomination d of a number to be entered. Operator pr derives p=f-d for supply to operator PtD and to generator ECE which feeds p space codes to the next p successive positions in buffer M2. Bi-stables CD and 1-9 are reset and set respectivley to prepare for the first digit entry keys from 1-9, bi-stable BSZ remaining reset at this stage to detect erroneous entry of a non-significant zero. For each digit entered, the corresponding digit code is supplied to buffer M2, and a pulse DE is fed to operators FIS and PtD to respectively detect the first significant digit entry and to decrement the value p to detect the stage at which the decimal point should be automatically inserted by a generator EPtD. Between each key stroke, a last entry correction key TCDC may be pressed to delete the last entered code in buffer M2 and cancel the last pulse DE fed to operators FIS and PtD. Finally an authorization key is pressed TVm to generate a flag code ECV provided the last but one position of M2 has been filled.

Abstract: 741,370. Duplicating-machines. FORD, Ltd., F. R., and FORD, R. M. Nov. 24, 1953 [Nov. 24, 1952], No. 29591/52. Class 100 (2). In a duplicating-machine of the kind having a device for moistening that surface of the copy sheet which is to receive an impression from a hectographic master sheet, the moistening device includes a moistening roller and a co-operating pressure roller, the latter having a sleeve of porous or absorbent material which, as shown in Fig. 2, is formed as a tensioned winding of absorbent material such as felt strip. As shown in Fig. 1 the moistening roller 21 is mounted above the path of feed of the sheets 15 and applies liquid from a reservoir to the upper face of the copy sheet, this face then being pressed by impression cylinder 13 against the master cylinder 12. The moistening roller has a smooth rigid surface and receives liquid through a wick 29 dipping into a reservoir trough 28. The pressure roller 22 is mounted on bell-crank levers 25 and urged by springs 26 against the roller 21. The rollers 21, 22 are driven either in timed relation to the feeding roller 16 or at the same speed as the printing couple so that sheets fed to them are forwarded to the trip between the master cylinder 12 and the impression cylinder 13. The pressure roller consists of a core 30 and a surrounding covering of felt which may be between inch and “ inch  thick. As shown in Fig. 2, the strip 34 forming the covering layer is wrapped helically round the core and secured at the ends by screws 37. Longitudinal fibres or a woven material may be embodied in the strip of felt to increase the tensile strength. Axial flow of moistening liquid is reduced by the circumferential interruptions in the felt covering. The fibres of the felt may be arranged to be predominantly radially and circumferentially to facilitate trueing up the surface by grinding and to reduce liquid flow axially of the roller. Instead of felt, absorbent paper or a woven textile fabric may be used. Alternatively a combination of these materials may be used. The core 30 may be of a synthetic resin, a metal such as aluminium or steel or of hard rubber. Specification 729,545 is referred to.

Title: A new or improved control system of a steam generating and turbine unit
IPC: F01K13/02
Filed: 1959-09-02
Abstract: 891,323. Steam turbine plant. SULZER FRERES S.A. Sept. 2, 1959 [Sept. 3, 1958], No. 29931/59. Classes 110 (3) and 122 (3). [Also in Group XXXV] A control system for a steam turbine plant in which the fuel supply to the steam generator K is controlled by the steam pressure and the steam supply to the turbine T, N is regulated by a device Z responsive to turbine speed is characterized in that with a drop in steam pressure at the turbine inlet below a predetermined value the speed control device Z is influenced as a function of the steam pressure in the sense of decreasing the turbine speed with pressure drop. Movement of steam pressure gauge i is transmitted electrically through a transformer m to a control amplifier r feeding servomotor s controlling the fuel supply to the generator K, the fuel rate variation being fed back to the amplifier r through a differential unit o coupled electrically to a steam flowmeter n. The device Z controls the turbine inlet valve V to control the turbine at a speed determined by a servomotor a whose setting is variable by remote control switch d acting through a motor e and a teletransmitter f coupled to the input side of an amplifier c for the servomotor a. The output signal of transformer m is fed to a compensation unit k which neutralizes the signal by means of a follow-up motor so that it is ineffective whilst the steam pressure is above the set value. When the pressure falls below the set value the compensation unit k allows a signal, corresponding to that received from transformer m, to pass to the input side of amplifier c to thereby influence the setting of device Z so that the turbine speed is decreased with falling steam pressure. To ensure that the input signal to amplifier c from unit k overrides the adjusting and feedback signals from teletransmitters f and b respectively, the latter signals are fed through a limiting device g. The unit k may also be arranged to pass a signal to amplifier c when the steam pressure exceeds a certain value, the consequent increase in turbine speed tending to lower the steam pressure to normal. In emergency, the compensation unit k may be bypassed, the signal from the gauge i being fed direct to the amplifier c.
