Title: Information recording system
IPC: G06F3/06
Filed: 1964-03-26
Abstract: 1,064,948. Digital data storage. POTTER INSTRUMENT CO. Inc. March 26, 1964 [April 5,1963], No. 12812/64. Heading G4C. A digital data storage system includes means for transferring information to a storage medium such as a magnetic tape employing two buffer stores which are operative alternatively, whereby the information is recorded on the tape with a predetermined format irrespective of the rate at which it is received. For the magnetic tape storage system described there are two modes of operation which may be selected manually: (1) continuous tape motion for a high input or output transfer rate and (2) start-stop tape motion for a low data input or output transfer rate.  Input to tape.-(1) Continuous tape motion. Data received at a relatively high rate from an input circuit 38, Fig. 3, is supplied via a control circuit 42 to one of two magnetic core buffer stores A, B. When sufficient data to fill the buffer has been received, a counter (Fig. 5, not shown) in the control circuit 42 is effective to cause subsequent input data to be entered into the other buffer store and the contents of the full buffer to be transferred to the tape 32 at a higher rate than the arrival rate of the input data. (2) Start-stop tape motion. During the input of data which arrives at a relatively low rate, the tape 32 is stationary and the data is routed to one of the buffers assumed to be buffer A. When buffer A is full, the input data is switched to buffer B and the control circuit 42 issues a " tape-run-backward " signal to  cause the tape 32 to move backwards until a mark indicating the end of the previously recorded data is sensed, thereby causing the tape to move forward after a slight " over-run " backwards. When the mark indicating the end of the previously recorded data is again sensed a monostable multivibrator is triggered so that, after a predetermined time, data recording is initiated. The spacing between, successive "quanta " of data, each quantum corresponding to a full buffer load, is thus rendered constant.  Output from tape.-The required output mode continuous tape motion or stop-start tape motion is selected by operator control of a flipflop (Fig. 4, not shown) and the output proceeds in a generally similar manner to the input, the buffers A, B being filled alternately.

Title: Improvements in or relating to apparatus for reeling and unreeling materials in strip form
IPC: B21C47/00
Filed: 1959-04-16
Abstract: 909,678. Control of D.C. motors. GRAH, H., [trading as SUNDWIGER EISENHUTTE MASHINENFABRIK GRAH & CO.]. April 16, 1959 [Feb. 9, 1959], No. 12949/59. Drawings to Specification. Class 38 (3). Reels for winding or unwinding strip material are coupled through variable ratio gearing to D.C. shunt machines regulated to have constant power, the machine coupled to the unwinding reel being operated as a braking generator. The braking torque is kept substantially constant over a wide range of strip speeds, the range of strip tension being extended by adjusting the gearing which provides two values of armature speed for each value of strip speed. This enables low tensions in the strip material to be maintained with accuracy since the corresponding speeds of the braking machine are small. The machine coupled to the take-up reel and operating as a motor is similarly coupled to the reel through variable ratio gearing.

Title: Improvements in magneto generators
IPC: H02K35/02
Filed: 1937-05-08
Abstract: 497,002. Interrupters. BENDIX AVIATION CORPORATION. May 8, 1937, No. 13203. Convention date, May 9,1936. [Class 38 (v)] [Also in Group XXXV] In an ignition magneto having an oscillating rotor, the closing and opening of the interrupter in the primary circuit depend on two positions of the rotor so that generation of current occurs during movement of the rotor in one direction and is prevented during the greater part of the movement in the other direction. At one end of the machine, the rotor shaft carries an element 17, Fig. 3, having a projection 16 which is engaged by a shoulder 15 on a lever 13 pivoted at 14 to a slide 7. The slide 7 co-operates by means of a roller 8 with an engine driver cam and is forced to the right against a spring 9 whereby the rotor is turned anticlockwise against a spring (not shown). Continued movement of the slide causes the lever 13 to be raised by a cam 21, the position of which is adjustable by a pivoted lever 24 engaging an aperture 28 in the cam, with the result that the shoulder 15 releases the projection 16 and the rotor is rotated rapidly in a clockwise direction by the cocked spring. A spring urged plunger 41 co-operating with a shoulder 42 on the member 17 cushions the return stroke of the rotor. In order to prevent generation of current during the anticlockwise movement of the rotor, the interrupter maintains open the primary circuit and for this purpose, the cam 51, Fig. 4, is pivoted to the other end of the rotor shaft and is actuated at the termination of each rotor movement by a pair of shoulders 61, 62 fixed to the shaft. A spring detent 65 co-operating with depressions 66, 67 maintains the cam in the operative or non-operative position.
