Abstract: 1,259,613. Tyre pressure indicator. A. MIRSKY. 22 Oct., 1969 [22 Oct., 1968; 10 April, 1969], Nos. 50089/68 and 18563/69. Heading B7C. A device for initiating a radio signal when the pressure in a tyre or other pneumatic or hydraulic pressure falls below a minimum value or rises above a maximum value comprises a first movable member 3 whose position is dependent on the pressure and a second movable member 4 for initiating the signal, e.g. from a radio transmitter 13, the members 3 and 4 being normally linked, but disengageable so that the member 4 can be set in an initial position while the member 3 is subjected to a setting pressure, thereby enabling the device to operate over ranges of pressures each dependent upon the value of the setting pressure. A pressure chamber 1 contains resilient bellows, of natural extension A, connected to a metal bar 3 which is linked to a pinion 4, rotatable on a pin 5, by intermeshing teeth or respective milled and rubber surfaces. The bar 3 projects through a hole in the device housing 7, the hole being normally closed by a rubber sleeve or cap 16 which is, however, deformable by a manual or mechanical force in direction 17 to displace the bar 3, thereby disconnecting it from the pinion 4. A contact stud 10 mounted on a mica/copper laminate plate 11 is contacted by a leaf spring 8 at the lower pressure limit for actuating the transmitter, the spring 8 resting against a limit stop 9 when the pinion 4 is in its initial position, under the action of a leaf spring 6. Alternatively, the stop 9 may be used as a high pressure contact by wiring it to stud 10 with the spring 8 in a position intermediate the contacts 9 and 10 when the pinion 4 is in its initial position. The contacts 9 and 10 may be resilient, instead of contact 8. The connection of an air supply line or gauge may be arranged to cause the displacement of the bar 3. The transmitter 13 is powered by a battery 14 or a built-in generator, Fig. 2 (not shown), comprising a coil (23) mounted on springs (24) between magnetic poles (21), (22) and connected to an accumulator and rectifier, the coil being oscillated by wheel motions. Alternatively, the magnetic poles are resiliently mounted.

Abstract: 1,265,801. Filling containers. PEMBROKE CARTON & PRINTING CO. Ltd. 3 April, 1969 [5 Jan., 1968], No. 738/68. Heading B8C. A container is filled with pulverulent material by charging a magazine chamber 12 from a supply source, filling a fixed volume chamber 31 from the magazine chamber and then transferring the contents of the fixed volume chamber to the container. Preferably the chambers are arranged one above the other with the outlets at the bottom and the pulverulent material is moved by gravity or differential gas pressure. The chambers are separated from each other, from the outlet and from the hopper by valves. The filler units may be located around the perimeter of a ring rotatable in a circular path and the magazine chamber may be filled from the hopper while the fixed volume chamber is emptying into the container. The pulverulent material is supplied to hopper 11 which is closed by valve 50. The material may be fluidized by air from pipe 11d passing through porous wall 11c. Valve 50 is operated by double acting piston 50d and seats against a rubber lining 50c on the walls of hopper 11. The magazine chamber 12 has porous walls 13, 13a, lined in parts with a non-porous layer 13b and is surrounded by wall 14 defining a cavity which can be connected via pipe 16 to a compressed air or vacuum supply for increasing or decreasing the pressure in the chamber 12. Flow of pulverulent material into the chamber is aided by air supplied through pipe 17 into the annular space surrounding the end of funnel 11. The base of the magazine chamber is closed by an inflatable valve comprising rubber members 51b supplied from the compressed air supply via pipe 51a. The fixed volume mounted below valve 51b comprises frusto-conical downward diverging porous walls surrounded by non-porous walls 14 to form a cavity 33 and closed at the base by a sliding plate 35. Below plate 35 is mounted the discharge nozzle 36 over which a bag 40 can be mounted. The bag can be evacuated via pipe 41 and may be held in place by clamps (not shown). The porous walls of the magazine and fixed volume containers permits the increase or decrease of pressure in these containers thus allowing the pulverulent material to be moved quickly under the differential pressure and increasing the compaction of the material.

A spark chamber apparatus for detecting radiation comprises two plates 2, 3 each coated over part of the area of one face with a thin electrically conductive layer 3, 4 forming an electrode, a non-conductive glaze 7, 8 being fused along the boundary zone between said layer and plate, and the plates being secured in spaced parallel relationship by a seal 9 around their peripheries. The seal 9 is preferably glass. In a further embodiment (Figs. 3 and 4, not shown) the spacing is fixed by several small spacers of glass or ceramic. The layers 3, 4 may be of tin oxide and are provided with Fe-Ni alloy leads 5, 6. The chamber is filled through a tube 10 to a pressure of about 1 atmos. with He Ne or a mixture of He or Xe to which alcohol may be added as a quenching agent. The plates 2 or 3 are of glass or in an alternative embodiment (Figs. 5 and 6, not shown) are of metal, thus providing a chamber in which the spark discharges cannot be observed or photographed, but which can be connected to a counter to indicate the spark current. The metal plates may be of Fe-Ni alloy with double layer electrodes of Cu or Ni and are spaced by a square ceramic frame. Two or more chambers as shown may be superimposed with adjacent chambers sharing a common glass plate to provide a multistage apparatus suitable for measuring strong and weak radiation. A two-stage apparatus is described (Fig. 7, not shown) in which one chamber is filled with a mixture of 98À2% He and 1À8% difluoromethane which with radiation stronger than 10 ÁC and an impressed voltage of 1450 volts produces sparks which can be photographed. The other chamber is filled with a mixture of 99À1% He and 0À9% difluoromonochloromethane which with radiation weaker than 10 ÁC and a voltage of 1000 volts produces sparks which are too weak to be photographed but the currents of which can be detected by a counter. For detecting weak radiation, the effective thickness of the glass plates 1 and 2 may be reduced by providing a large number of small holes in the outer surface of one or both plates (Figs. 8 and 9, not shown). These holes may be filled with synthetic resin (Fig. 10, not shown).

By reversing the drum drive, the hides can be augered out of the drum upon completion of the processing. Draining of the treating liquid can be effected without stopping the drum, e.g. for rinsing, drain openings 41 having removable covers 42 being provided for this purpose. The drain openings 41 are arranged as one or more rows of circumferentially space openings, or may be replaced by a drain in the lower end of the drum. An annular filter mesh 43 is arranged within the drum opposite each row to filter the liquid being discharged. Suitable conveyers or/and shoots may be provided for feeding hides into the drum and for receiving the leather as it is augered out of the drum.

This chain stitch ensures that the trebles are at right angles to the rows. A method of plain treble tricating involves the following steps: passing yarn around the hook, inserting the hook into a preceeding loop 53, Fig. 3, passing the yarn around the hook, 55; drawing the yarn through the loop-arrow 56; passing the yarn around the hook 58, Fig. 5, drawing the yarn through two loops on the hook-arrow 59. The treble is completed by a chain stitch in which yarn is passed around the hook, 61 Fig. 7 and the loop drawn through the loop on the hook-arrow 62. The trebles are repeated onto each stitch of the previous row. The backward or lock chain row is accomplished by drawing loops of yarn through pairs of loops on the hook (arrow 81 Figure 18 not shown). The fabric may also be composed of double or triple trebles, or plaited trebles.
