Title: Improvements in or relating to offset printing machines
IPC: B41L39/00
Filed: 1962-10-30
Abstract: 972,347. Rotary offset printing machines. W. RITZERFELD, and G. RITZERFELD. Oct. 30, 1962 [Nov. 9, 1961], No. 40923/62. Heading B6C. In an automatically operated rotary offset printing machine for effecting selective printing from a master sheet 25, this sheet and successive copy sheets 27 are carried by a rotatable cylinder 1 past swingable and electromagnetically operated offset rollers 7 and 5 the roller drive deriving from the cylinder through gear trains 9, 11, 13 and 9, 10, 12. The machine also comprises an electromagnetically operated offset roller washing device 16, master sheet damping systems 17 and 18, an inking mechanism 19 ... 21 and a suction operated copy sheet feed device 26. The machine is automatically operated through electromechanical apparatus which comprises a suitably arranged contact arm 3 rotatable with the cylinder and having an actuating tip 33, a keyboard 28, a fixed contact bank 4 carrying appropriate contact studs such as 29 ... 31 and contact rings and half-rings 46, 42, 51 and 48, 50, a limit switch 34 operable by the tip 33, relays and electrical circuitry and electromagnets 8, 6 and 38 for actuating the roller 7, the roller 5 and the washing device 16, respectively. In operation keys on the keyboard 28 are actuated to select the particular lines or sections of the master it is required to print on each sheet 27. The machine produces a printed copy sheet every revolution of the cylinder 1, alternate sheets coming from the same offset roller. Each roller receives an image from the master sheet and transfers it to a copy sheet every other revolution of the cylinder the operational movements of roller 5 being as follows-roller 7 has identical movements but, relative to the rotating cylinder, lags by 360 degrees during passage therebeneath of the inked master and dependent upon the keys which have been actuated the roller trips " in " for every desired line or section and then is held off with further rotation prevented by a pawl and ratchet mechanism 52. The copy sheet immediately following the master is printed on by the already prepared roller 7 whilst the roller 5 is automatically rotated in a reverse direction by an electromagnetic clutch arrangement 14 to a position in readiness for its printing operation on the passage of the next copy sheet therebeneath. During this printing operation it is swung into contact with the copy sheet and rotated through one complete revolution. When sufficient copies have been printed the main switch 32 is opened manually and the machine continues to operate until the tip 33 actuates the switch 34 which now de-energizes a relay 35. This simultaneously effects deenergization of the offset roller control apparatus and energization of the electromagnet 38 which swings the washing mechanism 16 against the rollers cleaning the same in readiness for the neck printing operation.

Filed: 1972-09-12
Abstract: 1403047 Automatic control of temperature BORG-WARNER CORP 12 Sept 1972 [17 Sept 1971] 42229/72 Heading G3R A motor operated valve in a refrigeration system is controlled by fixed frequency pulses of varying width, the width being proportional to the value of a control signal responsive to temperature. A reference signal and a temperature sensor signal are compared and the difference appears as an error signal on line 160'. The motor has two windings, 36 "C", 36 "O", energization of which respectively causes closing and opening of the valve. The error signal is fed into two similar signal channels each of which controls one motor winding. In each channel the error signal is fed to the negative input of an operational amplifier 324A or 324B, sawtooth waveforms from generator 325 and phase-splitter 301 being applied to the positive inputs, one sawtooth waveform being positive going and the other negative going. Positive error signals cause negative pulses, whose width is proportional to signal amplitude, to appear at the output of amplifier 324A, the pulses being inverted in logic gate 326A, the other gate input being connected to an overcurrent protection current module 50. A further inversion is made in circuit 326B the output of which switches transistor 411 which in turn triggers triac 415 to energize motor winding 36 "O". The channel dealing with the negative error signals is similar except that there is only one logic gate circuit.

Abstract: 1359356 Radio signalling INTERNATIONAL STANDARD ELECTRIC CORP 13 Sept 1971 [14 Sept 1970] 42551/71 Heading H4L A broadcast system comprises a first station broadcasting a first programme and a second station which may be brought into operation to broadcast a second programme, e.g. road condition information, together with a pilot frequency amplitude modulated by an auxiliary frequency, and a receiver normally tuned to the first programme and having means to receive the pilot frequency and to derive a control signal from the auxiliary frequency automatically to switch the receiver to receive the second programme. In one arrangement, Fig. 1, two receivers 2, 4 are required for the traffic radio station and entertainment broadcast station, respectively, normally connected as shown by switch 5 to pass the signals from receiver 4 to the reproducer 7. The output of receiver 2 is supplied via a circuit 8 tuned to the pilot frequency, amplitude demodulator 9, filter 10 selecting the auxiliary frequency and rectifier 11 providing a control voltage to change over the switch 5 to connect receiver 2 to the reproducer 7. In a modification, Fig. 2 (not shown), in which the auxiliary signal is transmitted by all the stations when traffic information is being broadcast, the local oscillator of a single receiver is adjusted to switch over to the traffic information station when the pilot signal and auxiliary frequency are detected by a circuit 8, 9, 10 as in Fig. 1, the output of filter 10 being supplied via a fixed delay to the oscillator tuning control circuit. Tuning may be changed. by switching in different capacitors or by a varactor diode. On switching over to the traffic information station the switching is maintained. by the auxiliary signal transmitted by that station. The control voltage may be arranged to start a signal seeking arrangement sweeping through a frequency range reserved for traffic information broadcasting. An auxiliary signal of different frequency from that used by the entertainment broadcast stations may be used by the traffic information station so that when this frequency is detected, the signal-seeking operation is stopped.

Th gears 5 also intermittently raise, &c. a pivoted wing 2 on the toy, to simulate its beating. The legs 25 are in two parts connected by pivots 28, and are mounted on a shaft 26 carrying a gear segment 27; a spring 29 biasses the shaft 26 to extend the legs. Air output gear 23 fast on an axially slidable shaft 22 is powered through the gears 5, a cam 21, 21a also powered through the gears engaging the end of the shaft 22 to slide it back-and-forth. In one end position of the shaft 22, the gear 23 meshes with the gear segment 27, so that the shaft 26 is turned and the legs 25 retracted against the biass of the spring 29. When the shaft 22 moves to its other end position under the influence of the cam 21, 21a, it disengages from the gear segment 27. The shaft 26 is thus released, and the spring 29 extends the legs 25 smartly. Having disengaged from the gear segment 27 as the shaft 22 moves axially, the gear 23 instead meshes a gear 32 fast with ground-engaging wheels 30, to which drive is accordingly clutched-in. The toy then moves forward, as if propelled by the extension of the legs 25. The gears 5 also power a cam 16, acting through a lever 4 abutting a pin 2a, to raise and lower the wing 2.
