Abstract: 1322683 Feeding sheets ADAMOVSKE STROJIRNY NARODNI PODNIK 12 Jan 1972 [13 Jan 1971] 1471/72 Heading B8R Raising and lowering pile tables.-A pile table raising and lowering device in a printing machine comprises a ratchet 9 arranged to be rotated in a first direction, to raise the table, by a control pawl 32. A securing pawl 33 coupled to the control pawl prevents slip of the ratchet. The ratchet shaft carries a rotatably mounted sleeve 11 which is drivingly coupled to the ratchet by a pin 16 on the sleeve and a pair of projections 17a and 17b on the ratchet. A friction brake 15 is mounted on the sleeve 11 and is arranged to engage stop pin 19. When the table is raised by action of the pawl 32 on the ratchet, the sleeve 11 and the brake 15 are also rotated until the brake engages the pin whereupon the ratchet and sleeve rotate against the action of the friction brake. To raise the table by hand the sleeve is turned (by a knob, not shown) to rotate the ratchet. To lower the table the sleeve is rotated by hand in the opposite direction and entrains the ratchet through link pin 16. The brake 15 is also rotated until another portion engages stop pin 19 whereupon the sleeve slips against the action of the brake. In moving in this direction the brake engages a block 24 which disengages the pawls from the ratchet so permitting the reverse rotation. The pawl 32 is driven from a cam 26 through a pivoted lever 28. The table is driven from the ratchet through a rack 3 and pinion 2.

IPC: H04J3/16
Filed: 1970-01-13
Abstract: 1302121 Multiplex pulse signalling PATELHOLD PATENTVERWERTUNGS - UND ELECTRO-HOLDING AG 13 Jan 1970 [15 Jan 1969] 1667/70 Heading H4L In a communication system in which timedivision multiplexing of information from a number of sources takes place, a regular variation of the time-slot allotted to a particular channel enables detection at the called receiver and the setting up thereat of a corresponding regularly-varying slot timing signal for extracting the information. As described (Fig. 5) in connection with a system employing a timecompression ratio of 100 and a 4-slot cycle of varying slot positions in a frame, the timing at the transmitter for a cycle of four bursts from a single source X derives from a recirculating store S 1  with taps connected to a modulator BM, the timings d 1 -d 4  representing the position of the bursts in successive frames. At the receiver, incoming signals are loaded into S2, having a similar four-frame capacity, and an AND gate arrangement at tapped outputs representing the receiver "address" detects when the multiplex transmission contains bursts at the desired time-spacings and inserts a pulse into S3. After a four-frame delay this pulse passes to an AND gate K where if a further pulse from S2 is received simultaneously, switch W is closed to set up S3 as a recirculating timer for burst selection at BD. Fig. 5a (not shown) illustrates a modification in which recirculating registers without tapped outputs and with a capacity of n (for example 400) bits, and containing four l's at the appropriate burst position at each of four successive frames replace S1, S3, and a further such register with capacity n - 1 bits replaces S2, the recirculation rate of S2 and S3 being n times that of S1 so that the data in S2 is shifted one bit position in each cycle until a comparison at K (effected by a count of the output bits of an equivalence circuit) indicates detection of synchronism. Fig. 6 (not shown) illustrates the use of two sets of taps on the stores S1-S3 of Fig. 5 to utilize two cycles of frames for a calling code, by switching between the two sets at intervals determined by a programme unit.

Title: Improvements in locking mechanism for automatic lifting barrier machines
Inventor: HILL DAVID ROBERT
IPC: B61L29/24
Filed: 1960-01-18
Abstract: 925,532. Gate-operating appliances; electrically operated fastenings. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 18, 1961 [Jan. 18, 1960], No. 1763/60. Classes 44 and 65 (1). A mechanism for locking a lifting barrier arm at any predetermined point in its movement comprises a stop member 15, e.g. a steel or hard metal ball, engageable in one or more indents 16 in a disc 17 on the main drive shaft of the arm and a collapsible linkage system 18, 21 movable between a substantially straightened position, in which the stop member is operatively engaged with the disc, and a collapsed position in which the stop member is inoperative, both positions being dependent on the electrical condition of a solenoid 10. As shown in Fig. 1, when the solenoid is energized the link 18, which is pivotally connected to a piston 14, and the link 21 are picked up by the plunger 12 of the solenoid into a substantially straightened position in which the ball 15 is held by the piston in engagement with an indent 16. A stop (not shown) prevents the links from reaching the fully strengthened position. When the solenoid is de-energized, the force acting on the disc 17, e.g. the gravitational pull on the barrier arm, is sufficient to cause a cam edge 25 at one side of the indent to force the ball 15 and piston 14 back into the cylinder 13, thereby collapsing the linkage and allowing the disc to rotate. When the arm approaches the end of its travel the solenoid is again energized so that the ball presses against and rolls on the perimeter of the disc prior to entering an indent. In a modification (Fig. 2, not shown) the linkage is forced to a slightly over-centre position by a strong spring and cannot be collapsed by a force on the disc 17 until the solenoid is energized to lift the linkage from the overcentre position to a " break " position against the action of the spring. In this arrangement the barrier arm is preferably balanced by a counterweight and driven in both directions by an electric motor.

Title: Improvements in Wireless Telegraphy with Undamped Oscillations.
Inventor: CLARKE EDWARD RUSSELL
IPC: H04B1/16
Filed: 1916-02-11
Abstract: 124,499. Clarke, E. R. Feb. 11, 1916. Wireless telegraphy.-A wireless receiving-arrangement for heterodyne working with undamped waves comprises a tuned aerial circuit coupled to one coil of an intermediate circuit having another coil coupled to a tuned secondary circuit, the intermediate circuit being without a condenser and containing the grid and filament of a three-electrode valve, and the inductance and capacity of the secondary circuit are in parallel in the hightension circuit of the valve. As shown in Fig. 2, the aerial circuit is coupled to a coil I<1>, in the intermediate circuit, which also includes a coupling-coil I<2>, the valve grid connected to terminal I, and the filament connected through a potentiometer to the terminal H. A secondary oscillating- circuit comprising an inductance M<3> and capacity D<2> is coupled to the intermediate circuit at the coil I<2>, and is connected through a telephone transformer F to the terminals E, 0 of the valve. The terminal E is connected to the filament, and the terminal 0 is connected through a high-tension battery to the plate or outer electrode of the valve. The secondary of the transformer F is in circuit with a telephone P. Oscillations set up by the valve owing to its grid circuit and plate circuit being inductively coupled at the coils I<2>, M<3> interfere with the received oscillations and give an audible note in the telephone P. The couplings L<3>, I, and M<3>, I<2> are preferably of the rotary type so as to give a loose coupling on either side of zero. In another arrangement shown in Fig. 3, fixed inductances and capacities are placed in the secondary circuit equal to those in the aerial circuit, and variable condensers C<2>, D<2> are piaced in the respective circuits and are adjusted jointly by rotating a common shaft so as to put the primary and secondary in tune with the incoming waves, as described in Specification 1402/15. Small variable condensers C<3>, D<3>, arranged one in each circuit, are subsequently adjusted by a common shaft but in such a way that as one is increased the other is diminished, so that both circuits are put slightly and equally out of tune with the incoming waves. The heterodyne note selected is that most suitable for the telephone employed, and the primary of the telephone transformer F is shunted by a variable condenser C<4> and tuned to this note. The telephone current in the coil F may be amplified by an auxiliary three-electrode valve, and a condenser placed between the terminal H and the corresponding terminal of the auxiliary valve.
