Abstract: 1,265,295. Pliers. FORGES STEPHANOISES S.A. 9 July, 1970 [11 July, 1969], No. 33318/70. Hoading B4W. A pair of pliers or wrench comprises handles 1 and 2 having jaws 1a and 2a respectively, the arms being pivoted together by a pin 3 and being biased apart by a spring 6. The pin has a spring loaded pawl 7 pivotally connected thereto, the pawl sliding in a notched slot 4. A spring 9 biases the pawl and handle 1 pivots in a slot 5 in handle 2. In operation, from an open position as shown in Fig. 1, closing of the handles causes spring 6 to urge jaw 1a toward jaw 2a to grip an object 11. In such a position the pawl is urged into locking engagement with a notch enabling further gripping pressure to be applied to the handles. On releasing the handles spring 6 forces them apart in which position the pawl 7 is disengaged from the notch.

Abstract: 1290063 Automatic exchange systems SIEMENS AG 17 Dec 1970 [19 Dec 1969] 59845/70 Heading H4K A switching matrix comprising a relay in series with a diode at each cross-point is provided with a first voltage supply for normally reverse biasing the diodes and a second voltage supply of opposite polarity and lower absolute value than the first for forward biasing a single diode and thus bringing up a unique relay when it is applied to a relevant row and column. In order to prevent a faulty diode, e.g. G43 from affecting the operation of more than its own relay when operate-potential is applied to a row and a column wire, it is arranged that the potential drop across Rx14 or Ry13, which occurs due to the immediate current flow through G43 when it goes short circuit, is less than the difference in magnitude between the first and second voltages. In this way it is ensured that the voltage on X4 when G43 is faulty, which voltage is less negative than the reverse bias voltage -U, is nonetheless still more negative than the forward bias voltage -u applied via y2 say when it is desired to operate a cross-point such as R32 whereby relay R42 is not brought up inadvertently. Similar considerations apply for the fault voltage on Y3. The correct resistance value R for an individual Rx1m or Ryln resistor or for a common resistor which may replace either of these is obtained from the relationship where Z is the resistance of the coil of a crosspoint relay. The resistors Rxm, Ryn merely ensure bias circuit continuity during the operation of a column or row change-over contact xm or yn when it is desired to actuate a crosspoint. The system is a development of that in Specification 1,015,451. The switch is monitored for faults so that a faulty cross-point can be marked permanently busy in a path finder's memory map associated therewith. The arrangement also confines the fault to a single switch of a stage having common supply wires for each of the switches therein, an example being provided by Specification 1,171,075.

Abstract: 1295009 Windscreen wiper FORD MOTOR Co Ltd 3 Aug 1971 [11 Sept 1970] 36385/71 Heading A4F A windscreen wiper system includes a device for parking the wipers out of their normal wiping area. As shown in Fig.1 wipers 17 and 18 are oscillated between limits 19-21, 22-23 respectively by an electric motor rotating crank arm 11 continuously in a clockwise direction, link arm 12 and link members 13, 14 and 15. When the wiper switch is moved to the off position, the motor rotates in the anti-clockwise direction and by virtue of the eccentric mechanism, shown in Fig.3 moves the wiper blades to the positions shown in Fig.1, the motor then being switched off completely by a switch mechanism on the motor. As shown in Fig.3, link arm 12 is driven from shaft 26 via link 11, pin 27, eccentric member 28 journalled on the pin and an eccentric part 29 on the member 28 to which the link arm is journalled. When the wiper is operating and the motor turns clockwise, the eccentric member 28 is locked to the link arm 11 by means of a latch member 35 biased by spring 38 so that its end part 39 engages an aperture 44 in the arm formed by pressing out a tongue 46 (Cf also Fig.6 not shown). A further latch 36 is biased by spring 43 towards the link arm 12 and once each revolution drops down into a hole 47 in the arm, the hole having a sharp leading edge but a sloping trailing edge so that the latch 36 is cammed out of the hole each revolution (Cf also Fig.4 not shown). When the motor is reversed to park the wipers, the latch 36 now enters the hole 47 down the sloping edge and abuts the sharp edge when the shaft is half a turn beyond the position shown in Fig.3 and the eccentric member is constrained by the latch to move as one with crank arm 11 and therefore rotate relative to link arm 12. At this point latch 35 is opposite hole 52 in arm 12 and is cammed downwards by tongue 46 to engage hole 52 as the eccentric rotates relative to arm 12. After a further half revolution when the motor switches off completely, crank arm 11 is again in the position shown in Fig.3, but the eccentric member 28 is now turned 180 degrees relative to its position shown in Fig.3 (Fig.2, not shown) to effectively lengthen the link arm 12 and park the wipers in the position shown in Fig.1. Upon restarting the wipers, latch 36 rides up the sloping edge of hole 47 Fig.4 (not shown) but latch 35 engages hole 52 until a half revolution has been made when the eccentric member 28 and the link arm 12 again have the relative positions shown in Fig.2 (not shown), and spring 38 pushes latch 35 upwardly to engage link arm 12 and disengage the hole 52 in crank arm 11.

Abstract: 1296117 Landing gears JOSEF HAAMANN FREUDENBERGER WINDEN-UND HEBEZEUGFABRIK 22 May 1970 [22 May 1969] 24897/70 Heading B7J A vehicle landing gear comprises two supports movable by separate mechanisms 1, 2. Bevel gears 16 are mounted on a hollow rotary output shaft 17 within which extends an axially and rotatably movable input shaft 46. A two-speed transmission 4 provides a torque connection between the shafts 17, 46, and comprises an intermediate shaft 44 carrying a gear 42 and pinion 43 engageable respectively, in a first axial position of rod 46, Fig. 1A, with gears 47, 45 on the input and output shafts respectively. In this position shaft 17 rotates more slowly than 46. In a second axial position, Fig. 2, gear 47 engages a gear 49 integral with gear 45 and the input and output shafts rotate at the same speed. Gears 16 each engage a gear 15 attached to a spindle 14 which threadingly engages a spindle nut 13, fixed in an inner sleeve 12 of the respective mechanism 1, 2. Each sleeve 12 is axially movable within, but rotatably fixed relative to, an outer leg 11. Thus rotation of the input shaft 46 by a crank handle 6 causes rotation of the output shaft 17 at either of the two speeds, the bevel gears 16 thus rotating the spindle 14 so that inner leg 12 can be moved towards, or away from, the ground.

In a first embodiment, Figs. 1 and 2 (not shown).a plurality of blocks (2) comprising stabilized multi-strand super-conductors are placed between two plates (1) of normal metal leaving longitudinally extending spaces (4). The components are then bonded together by hot-rolling in such a way that the spaces (4) are not closed. Strengthening wires may be incorporated between the super-conductor elements. In second embodiment, Fig. 3 (not shown), a pair of strips containing groups of super-conductor elements are joined together by strips of normal metal placed between them along their edges and welded using a laser, a microplasma, diffusion or electron bombardment under vacuum or gas or using tungsten electrodes under inert gas. In a modification, Fig. 4 (not shown), the edge strips are formed integrally with one conductor strip. In a third embodiment, Fig. 5 (not shown), composite members are bent to form rectangular tubes and are welded together to form a strip with a plurality of coolant ducts. In a further embodiment, Figs. 6 and 7 (not shown), two composite members are placed together with interposed strips of a masking material, e.g. ink. The strips are then hot-rolled so that they are joined only at the gaps between the masking strips. The assembly is then inflated by internal fluid-pressure to separate the masked parts of the strips to form coolant channels. In a modification, Fig. 8 (not shown), the masking is omitted, the two members are welded together along their edges and the assembly is inflated to form a hollow conductor. The internal walls of the channels may be provided with grooves Fig. 10 (not shown), or with a porous inner surface layer, Fig. 11 (not shown), to aid cooling. The size of any of the arrangements may be reduced by cold drawing or wire drawing with or without a mandrel. The super-conductor elements may be of NbTi NbZr, NbTiZr, NbNiTa wires or of strips of Nb 3 Sn or Nb 3 AlGe. the ,stabilizing material may be Cu, Al or Ag and the channels may have square, round, rectangular or hexagonal cross-sections.

Abstract: 1297942 Leather tanning processes NATIONAL RESEARCH DEVELOPMENT CORP 4 March 1970 [4 March 1969] 11545/69 Heading C6C A process for improving the resistance to water penetration of a leather which results from tanning a hide or skin with a basic salt of a multivalent metal, e.g. chrome tanned leather, comprises treating the leather with an aqueous solution of a salt of a substituted alkylene dicarboxylic acid in which the alkyline chain contains up to six carbon atoms and is substituted with from 1 to 3 hydrophobic organic groups each containing from 6 to 22 carbon atoms, and further treating the leather with a salt of a multivalent metal. Preferably, both treatments with a salt of a multivalent metal use chromium sulphate, although aluminium, zirconium or cerium salts may also be used. The hydrophobic organic substituent groups in the substituted alkyline dicarboxylic acid preferably contain from 12 to 22 carbon atoms. In a preferred example, chromium sulphate tanned leather prepared from pickled stock is neutralized to a pH of 8 to 8À3 with sodium bicarbonate or ammonia and then treated with an aqueous solution of an ammonium salt o- C14 alkenyl succinic acid, the acid being sold under the Registered Trade Mark "Bavon", after which further tanning with chromium sulphate is carried out, the leather is rinsed, neutralized and dried. Benzyl alcohol or white spirit may be added to the solution containing the salt of C14 alkenyl succinic acid. Where a soft leather is desired, the leather may be treated with a mixture of sodium phthalate and sodium formate prior to neutralizing with sodium bicarbonate or ammonia. This mixture may alternatively be added to the cromium sulphate during the further chrome tanning step. Smooth grained leather may be obtained by lightly acidifying the leather on the outer surface to pH 3À0 to 4À0 after treatment with the alkenyl succinic acid salt.

Abstract: 1321866 Colour correction in photographic reproduction AGFA-GEVAERT 19 April 1971 [14 April 1970] 17751/70 Heading G2C In a method of reproducing a colour original on a photographic light-sensitive multi-colour material, the improvement comprises exposing prior to development, the layer of the multicolour material in which light-rays having a wavelength corresponding to a side-absorption of a dyestuff image of the colour original are recorded to a negative mask image of said dyestuff image, which exposure is in addition to the usual imagewise exposure of the multicolour material to the colour original, which may be a colour transparency. The photographic multi-colour material may have a transparent support and is preferably a reversal material. The negative mask image may be a photographic black and white transparency. In the description the layer of the multi-colour material in which the light-rays of the blue region of the spectrum are recorded, is exposed to a negative mask image of the magenta dyestuff image of the colour original thereby correcting for incomplete transmission of blue light by the magenta dyestuff. Similarly the layer of the multi-colour material in which the light-rays of the green region of the spectrum are recorded, is exposed to a negative mask image of the cyan dyestuff image of the colour original to correct for incomplete transmission of green light by the cyan dyestuff. One mask may correct two side absorptions e.g. a mask film exposed through a green filter to the original may be used to expose the copying material additionally through a blue filter and a red filter successively, or through a magenta filter simultaneously, in order to correct for the side-absorptions of the magenta dyestuff in the blue and red regions respectively.
