Abstract: 340,215. Forging-machines. BENEDETTO, G., 45, Dante Alighieri, Novara, Italy. Sept. 20, 1929, No. 28517. [Class 83 (iv).] Electric upsetting apparatus has means for regulating the current to prevent substantial increase of current when the work is upset. The machine shown is adapted for heading a bar at both ends and comprises a pair of electromagnetic vices 1 and a pair of anvils 4, the latter connected to slide blocks 6 actuated by racks 8 engaged by pinions on shafts 9 driven by a hand wheel 11 or by chain gearing from a pulley 12. The upper jaws of the vices 1 are fixed and the lower jaws are mounted on cores 2 of solenoids 3. The anvils and vices are connected by flexible leads to terminals 18. Whilst the anvils are moved inwards to upset the ends of the heated work the vices may also be moved inwards by means of a right-and-left screw 17 driven by bevel gearing from a cross-shaft 60 actuated from shaft 9 by cone pulleys 58, 59 and belt 13. For maintaining substantially constant current during the upsetting operation an automatic control transformer is employed, the secondary winding 43 of which is free to slide on the iron core of the primary 44 and is partly counterbalanced by a weight 48 working on a pivoted lever 46. Specification 340,224 is referred to.

Title: Improvements in or relating to locks or latches for vehicle doors
IPC: E05B65/22
Filed: 1922-02-08
Abstract: 192,748. Arondel, P., and Reeve, E. Feb. 8, 1922. Latches, sliding.-In latches for vehicle doors having a housing of the same interior crosssection as the latch bolt and secured in a cutaway part of the door by flanges, the securing flanges do not extend to the forward end of the housing so that upholstery can be more readily attached. In the form shown in Fig. 1, the spring latch bolt B slides in the housing A sunk into the door C. The housing has flanges A' for attaching by means of screws C<1>, the flanges not extending to the edge of the door, leaving the edge C<2> clear of metal so that nails or tacks can be inserted. The bolt is operated by a handle E pivoted by a screw F to the lower flange or the door and having a pin engaging a hole in the bolt. The housing is slotted at A<3> to allow movement of the pin, and a lug E<3> covers the slot to keep out dust. The whole of the casing except the slot A may be covered by upholstery, and the latch and its spring may be removed from the housing by removing the handle E. In the form shown in Fig. 4, additional readily detachable handles are provided. G<1> is the usual vertical handle detachably pivoted to the lower flange at G<2> and passing through upper and lower slots A<5> in the housing and engaging a vertical recess in the latch bolt. The exterior handle H is carried by a spindle H<1> turning in a bearing H<4> attached to the outer face of the door by screws, and a bearing A<6> in the inner face of the upper flange A'. By unscrewing the bearing H<4>, the handle H and its spindle H<1> and follower H<2> can be removed bodily, allowing the removal of the latch bolt. An arm J' turned by a square key fitting the boss J<1> can be turned into a recess in the lower face of the bolt to lock it against operation.

Abstract: 1,274,702. Feeding sheets. SHOREHAM PRECISION TOOLS Ltd. 9 July, 1970 [5 June, 1969], No. 28566/69. Heading B8R. In apparatus for handling strips of material, e.g. steel strip 15, stack supporting means, e.g. inclined guide plates 11, 12A, (12B),Fig. 1 (not shown) at three positions along the strip length, are provided and a plurality of longitudinally spaced separating means, e.g. a catch 22 on a reciprocable carriage 18 mounted on a pistoncylinder device 16 at each of the three positions, separate the strips successively from the bottom of the stack, transversely of their length, to guide means, e.g. the extensions of guide plates 12A, (12B) and guides 24, down which each strip gravitates to a feeding position against a driven member, a plurality of reciprocable devices, e.g. hydraulic pushers 46, being provided for holding the strip against switch means which actuate said driven member to feed said strip lengthwise. The strip may gravitate into a feeding position against horizontal idler rollers 26 and abut pressure switches 39 at each of the three positions, actuation of any two of which activates the pushers 46, which hold the strip against the switches 39, and activate a driven roller (27) and a dropping roller 35 to feed the strip lengthwise. The rollers 26, (27) may be mounted on a vertically adjustable frame member (50). A spring loaded gate 23 retains the strips in a stack until acted upon by the separating means. In an alternative embodiment, Fig. 5 (not shown), feed rollers (64) are rotatable about vertical axes and when a strip gravitates down guide plate 12A, it triggers a microswitch which activates pusher members having idler rollers 79 chamfered at 80 so as to engage the underside of each strip 15 and urge it into a vertical plane against the rollers 64, one of which is driven.

Abstract: 1,182,107. Layering fabrics. H. J. BASCOMBE. 16 Sept., 1968 [21 June, 1967], No. 28601/67. Heading D1S. Lengths of textile fabrics are laid-up for subsequent bulk cutting by first identifying selected points in a length of fabric to which successive layers of fabric are to be matched. These points are fixed in relation to a laying up table 10, the surface 11 of which is formed with a plurality of geometrically arranged pinhole apertures 13, by pins 21 inserted through the corresponding holes 13 from the reverse side. The pins 21 are mounted on a carrier 14 which renders them movable in a direction perpendicular to the plane of the table 10. Initially the pins 21 extend above the surface 11 by an amount sufficient to a selected number of layers of fabric. When these layers have been applied the pins 21 are moved upwards by means of 14, a further distance to impale more layers of fabric. The process is continued until the required total number of layers have been laid-up.

Heading G1N. An electrical differential pressure gauge comprises a rigid casing 2, 5, 6, enclosing two pressure-chambers 11, 12, separated by a wall 1 which carries an enclosure having side walls 30 and an end wall 18; resilient bellows 21 seal an aperture in wall 18 and are linked by a rod 30<SP>1</SP> to a bellows 23 sealing an aperture in wall 22 and the enclosure contains at least part of a device which, in response to displacement of the rod 31 corresponding to the pressure difference between the chambers, generates electrically a force opposing that acting on the rod. Movement of the compression rod 30<SP>1</SP> may be detected by levers 42, 44, which alter the impedance of coil 47 by shifting an aliminium fin 46 and unbalance a bridge circuit 82, Fig. 4. The imbalance is amplified, 83, detected, 85, and used to generate a D.C. drive 86, to an electromagnet 49 (Fig. 1) the moving coil 57 of which acts upon lever 44 against the initial displacement. The force on lever 44 is proportional to the square of the current drive, or may be directly proportional if a permanent magnet is used at 49. The compensator housing may be filled with a non-conducting fluid of low compressibility, e.g. silicon oil, a third resilient member 40, having an elasticity lower than that of the members 21,23,rendering pressure differential measurements independent of the fluid pressure which is itself temperature dependent. The zero setting spring 90 is adjusted by the threaded pin 91, and the leads to the external part of the electrical gauge, which is in a housing 70, (Fig. 2 not shown) pass through a bore 73 and are sealed therein by interleaved plastic, metal, and rubber plates (Fig. 3 not shown).
