Positive images are produced by imagewise exposing a supported silver halide emulsion containing a developer which tans exposed areas on heating, placing the exposed emulsion in contact with a supported transfer layer which contains a binder a carbohydrate with a pyranoside structure, a polymer of an ethylenically unsaturated monomer, an organic polyester, a polycarbonate or a polyamide and 10 to 80% by weight, based on the weight of the dried layer, of a printing dye and stripping the materials apart so that the transfer layer is transferred to the unexposed areas of the emulsion. The resultant product may be used as a spirit printing master or a thermographic master producing right-reading positive copies. The transfer step is preferably carried out under heat and the transfer layer may contain a plasticizer to assist transfer. The silver halide emulsion may contain hygroscopic compounds e. g. (polyhydric alcohols) or compounds which release water on heating (e. g. urea, sodium acetate or sodium citrate) to assist the heat development. Alternatively the back of the emulsion support may be moistened during development. The emulsion may also contain stabilizers for the tanning developer such as the bisulphite compounds of aldehydes and ketones.

Abstract: 1327241 Semi-conductor devices KOGYO GIJUTSUIN 12 Aug 1970 [12 Aug 1969 18 Sept 1969 14 Oct 1969 (2)] 38852/70 Heading H1K In a method of making an IGFET having a "base" region of the opposite conductivity type, within part of which the channel is induced, separating the source and drain regions, ahe "base" and source regions are defined at the same surface area by a process using a single mask. In a first embodiment, Figs. 4 and 5, the drain region comprises a heavily doped Si substrate 1 and a lightly doped layer la the surface of which is masked with SiO 2  and a window opened through which impurities are diffused to form the "base" region 2 of the opposite conductivity type. The wafer is etched to remove the oxide layer formed in the mask window during the first diffusion step and impurities of the same conductivity type as the substrate are diffused-in to form the source region 3 within the "base" region 2. The masking layer is removed from the gate electrode site and a thin gate-insulation layer 5 is applied, a window is opened over the source region and a layer of metal is de posited and photoengraved to form the gate electrode 6 and the source electrode 9. The drain region may be contacted on the lower face of the wafer or via a contact region diffused into the top surface simultaneously with the source region. The "base" region may be left floating or may be contacted via an extension region formed by a separate diffusion step, Fig. 6 (not shown). The source and drain regions are interdigitated below the gate electrode but the channel can be made short and of constant length because of the use of a single diffusion mask. Where the gate electrode overlaps the lightly doped portion of the drain region a depletion layer forms which reduces the feedback capacitance. In a modification, Fig. 8 (not shown), the substrate forms a heavily doped "base" contact region and is surmounted by a lightly doped layer of the opposite conductivity type which is to form part of the drain region. The "base" regior is formed by diffusion and extends into contact with the substrate and the source is diffused into the "base" region using the same mask. The heavily doped part of the drain region is produced by diffusion into the lightly doped drain layer simultaneously with the source diffusion.

Title: An explosive power assisted, hammer driven tool
IPC: B25C1/14
Filed: 1959-11-23
Abstract: 870,900. Cartridge-operated tools for driving fasteners. ADOLPH, J. L. Nov. 23, 1959 [Nov. 27, 1958; March 26, 1959; Aug. 28, 1959], No. 39622/59. Class 119. A cartridgeoperated tool for driving fasteners into material comprises a body 1, Fig. 3, in which are slidably mounted a cartridge plunger 8 and a drive plunger 9, the outwardly directed end of the plunger 8 terminating in a head 22 adapted to be struck by a hammer for driving the plunger 8 towards the drive plunger 9, the inwardly directed end of the plunger 8 having an axial hole 24 for reception of a cartridge 25. The outward movement of the drive plunger 9 is limited by engagement of an annular surface 14 on the plunger with an abutment surface 15 on the body, the inner end of the plunger 9 being adapted to fire the cartridge upon sufficient percussion therewith while the outer end supports the fastener 71 in a recess 72. The arrangement is such that the cartridge plunger 8, when hammer driven with sufficient force, causes the cartridge to come into percussive contact with the drive plunger 9 thereby detonating the cartridge and driving the plunger 9 for the extent of its limited outward movement whereby the fastener is forced into the material a distance substantially corresponding to this movement. As shown in Fig. 3, the cartridge 25 protrudes from the hole 24 to provide a cushioning effect for the impact of the plungers but in a modification, Fig. 6 (not shown), the cartridge 25<SP>1</SP> is fully inserted into the hole 24 and a spring 66 is provided between the plungers. The stem 20, Fig. 3, of the plunger 8 passes through and is slidable in a breech block 21 which is removable from the body 1 together with the plunger 8 for loading and unloading. For this purpose two radial lugs on the breech block co-operate with inwardly extending abutments on the body 1, the insertion of the breech block and plunger assembly being effected by the lugs passing between the abutments and then turning the breech block to locate the lugs behind the abutments. Various safety devices are provided which while permitting outward movement of the plunger 8, prevent inward movement except when released by forward movement of a sleeve 2 against spring action. In operation after loading and release of the safety devices, the cartridge plunger 8 is slowly traversed by hand along the bore 7 towards the drive plunger 9, if necessary pushing it for the full length of the inward travel. The fastener 71 is then inserted in the plunger 9 and the tool pressed towards the workpiece thereby pushing the fastener and plungers inwardly to the position shown in Fig. 4. The sleeve 2 is then stressed forwardly to release the safety devices and the head 22 then struck with a hammer to fire the cartridge and drive the fastener.

Abstract: 1,175,889. Uses of luminescence. CENTRAL ELECTRICITY GENERATING BOARD. 13 Nov., 1968 [30 Aug., 1967], No. 39623/67. Heading C4S. [Also in Division G1] A portable radiation measuring instrument comprises a casing, a thermoluminescent phosphor material holder movable from within the casing to a position outside the casing, heating means movable towards and away from the material when in the casing, means for generating an electric signal corresponding to the light output from the material when heated, means for integrating the signal and means for indicating the integrated signal. The holder comprises a drawer 19 containing a recess for a disc of LiF phosphor encapsulated in a plastics material and a self luminous light source for test purposes. The heating means comprises a Curie point soldering iron 1 having a bit inserted in a brass block 3. The iron is pivoted at 8 and is maintained in the up position shown by a spring 11 and is moved down by a plunger 12 of a solenoid 13. Initially, the drawer is pulled out, aligning the self luminous light source with a photomultiplier mounted in the casing 14 and permitting the thermoluminescent disc to be inserted in the recess of the drawer. When the drawer is pushed in the disc is aligned with the photomultiplier and with the heating block 3 when it is moved down. Inserting the drawer causes a timing circuit to operate the heater and move it down on to the disc for 20 seconds. Light from the disc falls on the photomultiplier whose output is integrated using either a 0.1 ÁF or a 10 ÁF capacitor. The appropriate capacitor is selected by using the difference in voltage of the capacitor and a Zener diode to control switching relays. The capacitor output voltage is fed to a field effect transistor, the current through which is fixed by a transistor held conducting by a Zener diode in its base circuit. The voltage output from the F.E. transistor is adjusted by a variable resistor in the emitter circuit of the current controlling transistor and fed via an emitter follower to a log output circuit comprising a 10 M# resistor and a junction diode. The voltage across this diode is fed via a pair of matched F.E. transistors to an ammeter having a logarithmic scale.

Headings B3B, B3C and B3L. A punch-, and die-, cutting machine comprises a tool-holder 21 on an arcuate slide 61 having an axis horizontally disposed above a work support 6, the slide being mounted on a carriage 15 reciprocable along vertical or oblique paths. The work support 6 is rotatable by an electric motor on a compound slide 5, 2. The slide 5 can be fed intermittently in synchronism with the tool 20. The tool-carriage guide 14 is angularly adjustable on a head 13 which can be swung through 180‹ to bring a second tool-holder 78 into operation. The holder 78 is rotated by a motor 7 through a clutch 75. The motor 7, through an infinitely variable belt-drive 8 and a gear-box 9, also rotates a cam 11 having grooves 19, 23 which respectively reciprocate the carriage 15 and oscillate the tool-holder on its arcuate guide. The groove 19 is engaged by a follower (24) on a lever pivoted on a shaft (25). The lever has a groove 27 to receive an adjustable block (28) pivoted to a sliding block engaging an arm 17 secured to the slide 15, the arm being connected to a counter-balance spring (37). By rotating a handwheel (26) on the shaft (25), the block (28) is adjusted to vary the tool-stroke; to adjust the limits of the stroke, the slide 17 is unclamped and adjusted by a shaft 34 and a screw 36. The groove 23 is engaged by a follower 38 on a lever 39 rocking on a pivot 40 and connected by sliding blocks to a lever 43. A pantograph bar 46 connected to the lever 43 moves a roller-slide 55 to pivot a lever 52 around a pivot 53 to raise a block 58 sliding in the end of the lever. The block 58 is pivoted to the tool slide 61 and causes it to move round the arcuate guides 22 on each side of the slide.

Abstract: 1518846 Rejuvenation of electrolysis membranes HOOKER CHEMICALS &  PLASTICS CORP 1 Oct 1975 [29 Oct 1974] 40153/75 Heading C7B An ion-exchange membrane which has been used to define part of the anode compartment of an NaCl electrolysis cell is rejuvenated by treatment with acid at pH 0À2 to 2À5 and below the working electrolyte pH to remove deposits from its anodic side. The membrane may be a cation selective fluoropolymer e.g. a laminated membrane with different cation-selective activity on each side, or having an SO 3 H gradient across its thickness. Treatment may be in situ in which case normal electrolysis is modified by acidifying the anolyte, reducing the current density, and diluting the NaOH on the cathodic side. If the membrane is removed from the cell it may first be treated in a glycerol/brine solution to prevent shrinkage. The deposits removed are Ca, Mg and possibly Fe oxides, hydroxides, chlorides and complexes and should also be removed from the cell base by flushing. Entrained deposits are either filtered out or, if dissolved, chemically precipitated. Treatment acids include HCI, H 2 SO 4 , H 3 PO 4 , citric, gluconic and mixtures.
