Patent GB-550412-A (GB)
Title: Improvements in or relating to machines for moulding butter and other substances
IPC: A01J21/02
Filed: 1942-01-15
Abstract: 550,412. Moulding butter &c. KUSTNER FRERES & CIE. SOC. ANON. Jan. 15, 1942, No. 603. Convention date, Jan. 6, 1941. [Class 87 (ii)] Butter is fed by a screw 2 through a channel 3 to cells 4 of a revolving element 5, the bases of the cells being reciprocable plungers 8. When the supply of butter fails, or when, for some other reason, filling of a cell takes longer than usual, the element 5 remains stationary until the cell opposite the channel has been filled. An electric motor drives a pulley 14 which, via shaft 12 and releasable coupling 13a, drives the screw 2. The shaft 12 is normally coupled by clutch sleeves 21, 22 to a shaft 20 which, via a shaft 19, drives a maltese cross which gives an intermittent movement to the element 5. The clutch sleeves comprise a pawl 23 pivoted on the sleeve 22 and spring-pressed to engage the (ratchet) sleeve 21, and a bell-crank lever 25 which, when pivoted clockwise, disengages the pawl. This disengagement is effected by abutment of the (rotating) lever 25 with a lever 11 pivoted at 11a and controlled via a rod 10 and pivoted lever 9 by the plunger 8 of the cell which is being filled. Normally, by the time the lever 25 has rotated to the position where it would strike the lever 11, the latter has been rocked out of its orbit by the elevation of the plunger 8 by the incoming butter, but if the butter supply fails the lever 11 is not so rocked, the levers 11, 25 engage, the pawl 23 is tripped, the shafts 12, 20 are dissociated, and the maltese cross and element 5 stop. The shaft 12, however, continues to revolve and operate the screw 2 until the cell is filled, whereupon the reverse movements occur, the maltese cross removes the filled cell and aligns an empty one with the channel 3. Immediately after removal of a filled cell, the screw 2 is stopped for a short time. This stoppage is effected by a cam 18 which moves an arm 17 and linkages 16, 15 to disengage the coupling 13a, which is re-engaged by an adjustable cam 28.

Title: Improvements in notching machines
Inventor: BERGMANN EWALD
IPC: B21D28/22
Filed: 1968-01-04
Abstract: 1,202,481. Metal feeds. L. SCHULER G.m.b.H. 4 Jan., 1968 [12 Jan., 1967], No. 683/68. Heading B3W. In a notching machine e.g. for stamping rotor or stator laminations, an indexing spindle on which a workpiece is mounted is driven by the ram drive of the machine, braked by non- positive braking means when notching is completed and is orientated to receive a fresh workpiece fed to it at a predetermined orientation by means of two stops such as rollers 6 on arms 5 of a fork 7 carried by a slide 3. Directly the drive has been stopped the slide 3 is moved by ram means 4 till the arms 5 are in the path of a counter stop 2 located eccentrically on the spindle itself or on a rotatable component of the drive of the spindle, at least one of the rollers 6 grinding the counterstop, if necessary, to a predetermined position between them. A contact set 9 actuated when the slide reaches this position initiates mounting of a new workpiece and may intiate return of the ram 4. Should the counterstop be angularly displaced by more than 100 degrees from its predetermined orientation the advancing fork 7 guides the counterstop to a position 180 degrees displaced therefrom. Non-actuation of the contact 9 and of a limit switch 10 normally actuated on the return movement of the slide 3 causes operation of the machine to stop. In the embodiment of Fig. 2 (not shown), the slide is replaced by a lever (26) pivoted about a horizontal axis (27) by a ram (4) and having rollers (6) mounted on laterally extending arms which embrace the spindle similarly to the yoke (7). In a further embodiment, Fig. 3, slides 12, 13 carrying stops 16, 17 respectively are moved toward each other by rams 14, 15, the ram 14 being the more powerful and a stationary stop 18, located outside the path of rotation 19 of the counter stop 11, determining the end position of the slide 12. In operation, first the stop 16 engages the stop 18 and then the stop 17 presses the counterstop 11 against the stop 16. A nose 21 on the slide 13 contacts a limit switch 22 when it reaches counterstop-engaging position which signals that a new workpiece can be mounted on the spindle and the rams retracted. If the counterstop 11, because of initial excessive angular displacement is not located between the stops 16 and 17 the nose 21 contacts a limit switch 25 which stops the machine. In the retracted position of slides 12 and 13 the noses 20, 21 respectively engage limit switches 24, 23 which indicate that the stops are outside the path of rotation 19 of the counterstop. In a still further embodiment, Fig. 4 (not shown) the movable stops comprise arms (30A), (31A) projecting radially from meshing rotary members (30), (31), the member (30) being rotated by a ram 4 via a crank lever (36) and the member (31) and carrying a cam (39) which carries out the functions of noses 20, 21 in respect of limit switches (22), (23), (25). The stop means may be a member or members driven by an electromagnet or electric motor and moved against fixed stops to orientate the counterstop.

Title: Circuit for digitally encoding an analogous colour television signal
Inventor: GEIGER ERICH
IPC: H04N11/06
Filed: 1990-11-01
Abstract: An analog digital conversion is provided for two color difference signals, for example for a recording according to a timeplex method. The color difference signals are adjusted in their amplitude at the input of the analog digital converter such that the modulation range of the analog digital converter is always fully used independent of the original amplitude of the color difference signal. The amplitude is restored back to its original value after a digital to analog reconversion. This results in an improvement of the signal to noise ratio during the transmission. The amplification provided to the various signals can be controlled by comparator circuits comparing the signal level with a reference signal.
