Abstract: 1,250,841. Stapling machines. LAMSON PARAGON Ltd. 26 Feb., 1969, No. 10348/69. Heading B4C. In a machine for stapling together sheets to form a book, groups of reversely shingled, collated sheets are fed to a stapling station S by a conveyer system comprised by endless bands 53, 12 driven by an electric motor M. The leading edge of a group first covers a photo-cell or photo-diode 202, and solenoid 37a is activated to raise a jogger assembly 32 comprised by a pivoted shaft 34, an arm 33, collar 39, and a pivoted pusher member 40 to its inoperative, dotted line position. Subsequently the leading edge of the group covers the photo-cell 252, and solenoid 135a (Fig. 5) is de-energized and pins 30, 31, which were previously retracted, are urged by spring 137 into their operative positions. Finally the leading edge covers the photocell 268. When the rear edge of the group passes the photo-cell 202 the solenoid 37a is de-energized, the jogger assembly moves to its operative position and the forked end of the pusher member frictionally engages two adjacent bands 12. The movement of the member will cause the rear edges of the sheets to be properly aligned when the sheets are pushed against the stop pins 30, 31. Subsequent exposure of the photo-cell 252 (coupled with the covering of photo-cell 268) energizes the solenoid 135a and actuates solenoid 102a to pivot a spring-biased pawl 102 and release, for one revolution, a pin 101 of the part of a clutch 100 which is fixed on a camshaft 89. Rotation of the shaft causes a cam 110 to actuate staples 80, 81 via a device 111 comprised by a pair of plates 112, 113 pivotally connected at one end (114) (Fig. 6, not shown), and separated by springs 115 at the other end. A further cam 120 suitably angularly positioned with respect to the cam 110 causes retraction of the stop-pins by depression of rod 121 against bias of spring 125 and consequent movement of the stop pins and an armature plate 135 towards the solenoid 135a. The shaft 89 includes a unidirectional clutch 143 and a friction brake 140 looped around a drum 141. Staple supply followers 147 actuate a microswitch 146 to illuminate a warning light 145 when the staple supply is exhausted. The assembled book is then transported to a receptacle (23) (Fig. 3, not shown). The control circuitry which comprises an arrangement of flip-flops, transistors, resistances, diodes and condensers includes means for preventing more than one stapling operation in one machine cycle.

Abstract: 1,266,287. Steering motor vehicles. CLARK EQUIPMENT CO. 22 May, 1970 [2 June, 1969], No. 24876/70. Heading B7H. A vehicle in which wheel assemblies C, D at each end of the vehicle are steerable, and two driver's stations A, B are provided adjacent the respective wheel assemblies, includes an arrangement in which a change in the steering mode can be effected by either wheel assembly under the control of either the adjacent or the distal driver controls, the change being effected by a wheel assembly C or D which is in the same relative position to the driver's station A or B from which control is being exercised, irrespective of which station A or B is functional. Driver's station A is associated, in the embodiment shown, with wheel assembly D. Steering cylinder A4 can be connected directly to tie rod 15 to steer the wheels, but as shown, operates a servo-valve D1 for supplying fluid to motors D3, D4. Movable with piston rod 13 of cylinder A4 is a wiper 14 of a variable resistor D5 in circuit with a battery D6 through a double-throw switch D7. The voltage tapped off by the wiper, in accordance with the extension of piston rod 13, is compared in a servo-valve 2 with a voltage arising from a similar cylinder- and-resistor arrangement associated with wheel assembly C. If both voltages are of the same polarity and value, the valve 2 performs no further function, but if the values differ valve 2 detects an error voltage and feeds fluid from pump 4 to cylinder B4 in such a direction as to eliminate the error voltage. Hence, any steering movement of steering wheel A1, impressed directly on assembly D, is also impressed on assembly C. If switch D7 is thrown to alter the polarity of the two voltages, a similar error voltage elimination procedure occurs but the steering mode is changed i.e. the wheels of assembly C will be turned for crabwise vehicle motion as opposed to circular motion about a centre outside or inside the vehicle. Steering wheel A1 operates pump A2 which moves slide valve A3, in dependence upon direction of steering, to allow fluid from pump A6 to reach cylinder A4. A further valve A5 allows station A to be rendered inoperative, or the steering directions at station A to be reversed for coordination with those at station B. Station B is associated with assembly C in a manner similar to that described for station A and assembly D. In another embodiment (Fig. 2, not shown), station A is associated with assembly C, and station B with assembly D. In such circumstances, valves A<SP>1</SP>5<SP>1</SP> and B<SP>1</SP>5<SP>1</SP> are two-position only.

Each output terminal is connected to the input terminal of an amplifying solid state electronic three-terminal element, which is integrated with the aerial system structure. The output impedance of the aforesaid filter, and the working point of the associated threeterminal element are designed to obtain an optimum signal-to-noise ratio over the frequency range concerned. As described, an aerial system comprises an insulating plate P on which are printed a coiled conductive strip 1 and a coiled pseudo-coaxial line having a centre conductor 7 which is an extension of the strip 1, and an outer conductor formed by two strips 2 containing the strip 7 and joined together at their ends. A top capacitor 3, which may be a motor-car rear mirror, is connected to the end of the strip 1, and a terminal 14 at the end of the strip 7 is for a lower-frequency range of operation. A terminal 8 at the end of the strips 2 is for a higher-frequency range of operation. There are also provided on the plate P a capacitor 9, through which the terminal 8 is coupled, and a part A containing the active elements and associated circuitry. The base of a transistor 4, Fig. 2, is coupled to the lower-frequency output of the aerial by a resistor 17 and an inductor 16, a diode 18 giving protection against static. A resistor 22 in the power supply line, in combination with a capacitor 23, provides protection against H.F. interference to the transistor 4. An additional amplifier comprising a transistor 6 may be included, and output is coupled to a common lead-out cable 29. A decoupling resistor 30 in the emitter circuit of the transistor 6 serves to suppress intermodulation interference. The higher-frequency output of the aerial is coupled by a capacitor 11 to the base of a transistor 5, giving output to the common lead-out cable 29. A choke 25 and a capacitor 26 block the lower-frequency output from the transistor 5. Instead of the common lead-out cable 29 a separate output may be provided for each frequency range.
