Abstract: 1,263,813. Photographic processing of diazonium material. PHILIPS GLOEILAMPENFABRIEKEN N.V. Oct.13, 1969 [Oct.16, 1968], No.50105/69. Heading G2C. Metal images are produced by imagewise exposing a material containing a diazosulphonate, an anti-regression agent, a saccharide containing an aldehyde group and optionally a buffer and/or mercurous and silver ions, contacting the exposed material with a bath containing at least 0À005 mol per litre of mercurous salt(s) and a minor amount of a silver salt(s) and intensifying the nuclear metal image thus produced by physical development. The materials used are preferably those specified in Specification 1, 242, 490. The material is imagewise exposed and treated in a bath of mercurous and silver nitrate followed by a physical developer containing ferrous and ferric salts. Less holes in the metal images of the same density are obtained by using the above materials and also by reducing the physical development time.

Abstract: 1,001,176. Transistor oscillator circuits. HAMILTON WATCH CO. Dec. 24, 1963 [Dec. 26, 1962], No. 50866/63. Heading H3T. [Also in Division G3] The frequency of a unijunction transistor oscillator, particularly for controlling a timepiece (see Division G3) is stabilized by delaying the pulses obtained from one electrode and feeding them back to another electrode. In Fig. 2, capacitor 26 charges from a supply voltage at 14 via resistor 24 until the voltage at the emitter of the unijunction transistor 12 is sufficient to trigger the transistor, discharging the capacitor 26 and giving a pulse in driving coil 60 the field of which interacts with that of a permanent magnet 58 let into the rim of a balance wheel 54 and rotates the wheel against the torque of a hairspring 56. Capacitor 26 now recharges via resistor 24 whilst the balance wheel 54 is being returned by the hairspring 56. After one complete oscillation of the balance wheel 54, the pulse induced in a trigger coil 62 by the magnet 58 is of suitable polarity to cause transistor 42 to conduct, reducing the potential at base 20 so as to trigger the unijunction transistor 12, discharging capacitor 26 through the driving coil 60 and initiating a further cycle. The natural frequency of the oscillator comprising components 12, 24, 26 should be slightly lower than that of the balance wheel 54. Pulses developed across a damping diode 38 are available at output terminal 32. The balance wheel may be replaced by the cascade combination of any mechanical or electrical time delay and an inverter connected between the two base electrodes of the unijunction transistor, as in Fig. 1, not shown.

The tool spindle also comprises fixed cutting inserts 28, Fig. 3, so that when the spindle is moved through a workpiece 26, Fig. 5, inserts 28 carry out a roughing operation, and insert 41 is retracted. After passing through the workpiece, wedge 50 is actuated so as to flex bar 45 and set insert 41 to the required cutting radius, the spindle is retracted through the workpiece, and the rough bored hole is finish bored. The spindle is provided with a rapid approach, a slower forward feed, and a slow return feed, and a rapid retraction to the position of Fig. 1. The spindle is rotated by an electric motor through a toothed belt and pulley 23, 22, which may also drive a second tool spindle 17<SP>1</SP>, Fig. 1. An adjustable stop 93, Fig. 2, is provided for limiting the movement of the wedge and therefore determining the cutting radius of insert 41, and adjustment of the stop so as to provide for correction when the insert wears, is by a reversible stepping motor (108), Fig. 9 (not shown), which drives a timing belt and pulley 111, 112, Fig. 2.

Abstract: 1301043 Slicing machines W KRAUT [trading as BIZERBA WERKE WILHELM KRAUT K G] 30 Oct 1970 [5 Dec 1969] 51616/70 Heading A4C A slicing machine having an adjustable thickness of cut comprises a reciprocating carriage 8, Fig. 1, a rotating planar circular knife 5, a conveyor 13 and a slice striker for depositing cut slices on a table 16, the machine being selectively operable in a "stack" mode, in which the table is lowered by a distance equal to the slice thickness during each cutting cycle, or in a "stagger" mode in which the table is moved stepwise horizontally away from the conveyer during each cutting cycle. The carriage 8 is driven via a geared motor and crank wheel which, during the rearward cutting stroke of the carriage, also drives, via free-wheels and an endless belt, superimposed spiked chains 14 of conveyer 13, the conveyer stopping as the carriage reaches its rearmost position in which it actuates a switch to operate the solenoid actuator striker 17 to pivot about a horizontal axis to knock a slice on to table 16. A food clamp 9 on carriage 8 is driven transversely to the axis of carriage reciprocation to move the material to be sliced towards the knife by a distance equal to the slice thickness in each cycle of reciprocation, an adjustable lever 22 striking a rack bar (37), Fig. 3 (not shown), slidably mounted on the carriage 8, on the return stroke of the carriage to rotate a shaft (38) stepwise via a pinion (35) and free-wheel (37). Rotation of shaft (38) moves clamp 9 via engagement with a nut plate (55). A control 107 adjusts the drive of table 16 so that it operates in the "stagger" or "stack" mode. In the "stack" mode reciprocation of the carriage 8 causes stepwise one way rotation of a spindle 119, Fig. 10 via movement of a spring tension lever system (124-130), Fig. 11 (not shown), a rack bar 132 and free-wheel 134, spindle 119 being releasably engaged by a nut plate 116 on the lower end of a vertical shaft 102 supporting the table. In the "stagger" mode a shaft 94, Fig. 9, which is rotated by the solenoid actuating the striker 17, rotates a gear 114 via a free wheel 157, causing pivoting of a feed lever 155 engaging the table 16 so that the table is moved forward during the return pivotal movement of striker 17. When the table 16 reaches a lower, or forward, limit position a limit switch is operated stopping carriage reciprocation. The table 16 may be returned to its starting position by a lever 145, Fig.1. The slice thickness may be infinitely adjusted between limits by a knob 12 which moves a guard 7 relative to the knife 5 and also adjusts the position of the lever 22 thus adjusting the distance moved by clamp 9. The knob 12 simultaneously adjusts the position of a stop (138), Fig. 11, engaged by the spring- tensioned lever system to thereby adjust the height that the table 16 is lowered in each cutting cycle.
