Abstract: 385,484. Luggage and like holders for motor vehicles. PAAPE, F. G., Oban Hotel, Octagon, Dunedin, Otago, New Zealand. March 15, 1932, No. 7636. [Class 103 (ii).] A tool or like box is adapted to be removably fitted between the front dumb-irons of a motor vehicle and has a beaded or corrugated hinged cover to which is detachably secured a luggage-grid. The box is supported at the rear by a beaded or corrugated part 2A co-operating with the ledge at the front of the radiator and at the front by lugs resting upon the inwardly-projecting nuts of the shackle bolts or by a bar engaging in a transverse recess 15C in the bottom 5 of the box and having end brackets fitting over bumperbar supports fixed to the front of the chassis.

Title: Keyboard digital signal generators
IPC: H03K17/967
Filed: 1973-02-16
Abstract: 1381433 Keyboards MARCONI CO Ltd 19 Sept 1973 [16 Feb 1973] 7683/73 Heading G4H In a keyboard, each key, when actuated, presses an electrically-poled plastic sheet in the region of a respective combination of a common plurality of conductors. As disclosed, the key presses a respective combination of the conductors against the sheet, the other surface of which bears a backing electrode, the output being between this electrode and the conductors, the effect being piezo-electric. In manufacture, after the backing electrode has been deposited on the plastic sheet and before the conductors are deposited, the plastic sheet is electrically poled by depositing temporary electrodes on the "conductor" side of the plastic sheet to correspond to each key area (or each conductor path at each key area), and a voltage is applied across the plastic sheet while it is heated and allowed to cool.

Title: Creasing apparatus, method and product
IPC: B26D3/08
Filed: 1959-03-06
Abstract: 888,215. Creasing box-blanks. INTERNATIONAL PAPER BOX MACHINE CO. March 6. 1959 [June 12, 1958], No. 7822/59. Class 100(2) A method of creasing paperboard to form adjoining, hingedly connected panels e.g. of a box-blank, comprises the steps of impressing a single, shallow furrow in one face of the paperboard along the centre line of the crease while simultaneously impressing a pair of shallow furrows in the opposite face of the paperboard, each laterally spaced from and parallel to the single furrow, and then continuing the pressure and deepening the furrows until the single furrow overlaps the pair of furrows and until the material of the paperboard located between the pair of furrows has been permanently stretched nearly to the point of fracture, thereby forming a compound crease consisting a double hinge. Opposed creaser bars 20, 21 are mounted so as to rotate in parallelism towards and away from the material to be creased; mechanism for effecting such rotation may be as described in Specification 876,331. The creaser bar 21 carries a single creaser blade 36 rigidly secured therein by set screws 39. The creaser bar 20 carries a pair of creaser blades 46, 47 which are mounted in lateral recesses on either side of a tapered central portion 53 of the bar. Pivot pins such as 62 carried by the portion 53 pass through holes in the blades 46, 47. The blades can pivot laterally between the tapered portion 53 and vertical cover plates 56, 57 which are fixed by bolts 58 to opposite sides of the bar 20. The blades are urged apart by coil springs such as 64 mounted in holes in the tapered portion 53 and their maximum divergence can be adjusted by means of a series of set screws such as 67, 68 which are threaded in the cover plates 56, 57. The effective height of the blade 36 above the upper face 42 of the bar 21 is substantially greater than the effective height of the blades 46, 47. As the bars 20, 21 are brought together to crease a blank 24 of corrugated paperboard the edges of the blades 36, 46, 47 frictionally engage the blank and form shallow furrows therein. As the creaser bars are brought to the position in which they are closest to each other, Fig. 5, the blades 46, 47 are caused to converge by reason of their frictional engagement with the blank and deep, overlapping furrows are formed in the blank. When the blank is formed into a box it may be folded about the crease through either 90 degrees, Fig. 9, or 180 degrees. The process is also applicable to laminated or pressed paperboard. In a modification of the apparatus the blades 46, 47 are replaced by blades of flexible resilient material such as spring metal.

Abstract: 991, 965. Textile treating apparatus. SVENSKA FLAKTFABRIKEN A. B. Feb. 25, 1964, No. 7879/64. Heading D1L. In a method for conditioning web or sheet like material, moisture is supplied to the material by blowing a heated, moist, gaseous medium against one surface of the material and at the same time blowing a cold, moist, gaseous medium against the opposite surface of the material, thereby continuously conducting away the heat released by the condensation of the moisture. The moisturesupplying medium may be heated moist air or steam and the conditioning may be carried out in two or more steps, the blowing sides for the heated and the cold mediums being alternately changed over. As shown the treatment is carried out in a closed chamber 1 having an inlet 2 and an outlet 3 for the material 4. The chamber is divided into three separate sections A, B, C each of which has a circulation fan 5 which presses the medium into a distribution box 7 having openings 8, such that the medium is blown against the upper surface of the web. The medium is returned via tubes 9 and heating and humidifying means to the inlet side of fan 5. A similar fan 12, distribution box 14 &c. together with cooling means is provided on the underside of the web 4. Shield means are provided on both sides of the web edges to prevent mixing of the two media and they are preferably constructed so that they form a longitudinal passage for sucking-off a portion of each of said media.

The apparatus may be used for welding or perforating using a laser beam, for producing local variations in the dyeability of fabrics and for making masks by a photolithographic process using an ultra-violet or visible lamp. In the embodiment described, the workpiece 7 is mounted on a drum 6 on to which a laser beam 2 from a CO 2  laser 1 is focused by a water cooled lens 5. The drum 6, which is supported by rollers 16, 17, Fig. 2, in a carriage 15, is rotated by a motor 26, via a shaft 27, toothed belts 28 and pulleys 29, and simultaneously translated along rails 24, 25 by engagement of a rack 32 with a pinion 30 which is driven from the shaft 27. A slotted disc 11 in the path of the laser beam 2 is rotated by a motor 12 so that a desired pattern of perforations is produced in the workpiece 7 The disc 11 and drum 6 may be rotated in synchronism or out of phase to vary the pattern of perforations by mechanically rotating the motor 12 in a mounting (40) (Fig. 3, not shown) by means of a cam (34) which is rotated from the motor 26 and which reciprocates a rod (37) to cause rotation of a gear-wheel (38) meshing with a gear wheel (39) on the motor casing. The power of the beam 2 is monitored by a detector 14 and a device for modulating the beam intensity may be provided in order to vary the size or occurrence of the holes. The beam 2 is passed through an asbestos sheet 4 and may be deflected by a mirror 9. A larger pattern may be superimposed on the pattern of perforations produced by using a mask (41) (Fig. 4, not shown) positioned on the workpiece.

Abstract: 1450268 Pistons POCLAIN 22 Feb 1974 [8 March 1973] 8273/74 Heading F2T In an hydraulic or pneumatic ram, a plurality of rings 40, 41, which divide the gap alongside a piston 3 into one or more sealed chambers 35, are axially slidable and resiliently urged by compression spring washers 42, which transmit a fraction of the force, exerted on the ring 41 by the fluid pressure in chamber 6, to the piston 3, so that the fluid pressure, which need be exerted in chamber 35 to maintain the ring 41 in a floating equilibrium position, is correspondingly less than that in chamber 6. The sealing members 43 of each ring 40, 41 are thus subjected, in use, to a difference in fluid pressure which is only a fraction of the total pressure in chamber 6. In use, working fluid is supplied, at low pressure, to port 9 and at high pressure to port 8. Port 7 is connected to exhaust. Sleeve valve 46 opens, against a weak spring 47, to allow chamber 35 to be filled with fluid. At the equilibrium position of ring 41, half the force exerted by the pressure of fluid in chamber 6 is balanced by spring washers 42 and the remainder by the pressure of the fluid in chamber 35. Sleeve valve 46 contains a valve 50, which acts as a safety valve when the end of stroke position (Fig. 3) is reached. The opening of valve 50a under high fluid pressure in chamber 35a dampens the end of the stroke. Sleeve valve 46 may be replaced by a simple form of non-return valve.
