Abstract: 1339278 Endless-track vehicles BLAW KNOX CONSTRUCTION EQUIPMENT Inc 22 Dec 1970 [31 Dec 1969] 60925/70 Heading B7H  An endless-track vehicle 31, particularly a paving machine, has endless tracks 39, each including, a track 61 guided by pivotally mounted bogie wheels 63 and a tensioning wheel 65 and driven by a sprocket 67. The track 61 includes a pair of bands 111 comprising sections 113 joined end to end, each including steel cables (115) embedded in anchor plates (117), Fig. 8 (not shown). The cables and anchor plates (117) are encased in rubber (119). The sections 113, Fig. 5, interconnect a plurality of shoes 131 provided with sprocket openings 133 to receive sprocket teeth 181, Fig. 2. Rubber pads (145), Fig. 6 (not shown), are connected to each shoe 131, each pad comprising a rubber pad (153), Fig. 4 (not shown), moulded to a plate (147). Bolts (157) secure the pads (145) to retainers 163, Fig. 5, having U-shaped walls 166. The sprocket teeth 181, Fig. 2, are carried by a drive sprocket 67 carried by a shaft within a transmission housing 191, Fig. 11, driven through bevel gearing by change speed gearing 204 driven by a hydrostatic motor 205. Separate drives are provided for each track 39, thus facilitating steering and turning the machine about its centre line. Each motor 205 is supplied with fluid under pressure by a pump 209 driven by an engine 49, through transmission. The pumps 209 also supply motors 217 which drive augers 45 and shafts 225 which drive conveyers for supplying paving material from a hopper to the augers 45. The engine 49 has a speed control, Fig. 17 (not shown), including a linear actuator (329) for actuating the throttle (327), the actuator being controlled by limit switches (335) operated by transmission control levers (337).

Patent GB-2013102-A (GB)
Title: A filter material and its manufacture
IPC: A62B19/00
Filed: 1978-06-23
Abstract: A filter material, for example for use in the construction of safety clothing, gas masks or the like is made of an open-pored foam polyurethane (1) with adsorber particles (2) adhered to the pore walls and porous adsorber grains (4) placed in the pores. In a process for making the material the adsorber grains are forced into the foam, which is wetted with water, by means of an air current. The foam may be reinforced by means of a fibre layer (5) to prevent distortion of the pores and possible escape of the adsorber grains therefrom. The adsorber is preferably active carbon made by carbonizing coagulated viscose drops. The material is stated to prevent passage of liquid droplets as well as vapours. <IMAGE>

Patent GB-2066363-A (GB)
Title: Deep-well and pipeline pumps
IPC: F04D13/10
Filed: 1979-12-28
Abstract: A motor-pump unit, particularly but not exclusively for location in the downbore of a deep offshore oilwell, comprises a small diameter multi- stage fluid turbine, e.g. having at least thirty axial-flow stages, coupled to a multi-stage pump, e.g. of mixed-flow type. A portion of the oil pumped by the pump is cleaned, pressurized and returned by a conduit to drive the turbine, and on discharge from the turbine the portion mixes with freshly pumped oil being delivered to the head of the well. In contrast to previous units which employed an electric motor located at the bottom of the well, the present pump unit can be advantageously located at any suitable intermediate position in the bore and thereby operation and maintenance of the unit is considerably convenienced. Additionally, the present unit provides much greater pumping power than previous electrical units so enabling usage in very deep wells and the provision of greater capacity.

Patent GB-2056137-A (GB)
Title: Improvements in sheet counting apparatus
IPC: G06M9/02
Filed: 1980-07-03
Abstract: Suction operated sheet counting apparatus is stopped when the vacuum in the currently operating suction unit drops below a given level but only after a predetermined delay allowing the unit to move to a predetermined position in its counting cycle. The delay prevents counting operation being stopped when the low vacuum is caused by initial sealing problems in an otherwise correct count, e.g. when counting crumpled banknotes. The suction pads 4-8 are sequentially connected to a vacuum source V monitored by switch S1. This switch is only effective to stop counting when suction unit has reached a given position determined by cams 14 and switch S2. <IMAGE>

The stream flows into a compartment (3a) of an electrolytic cell (1) (Reynolds number 7200) at a rate such that (cell voume)/(flow rate) is 0.03 seconds. A pH electrode down-stream of the cell (1) measures the pH. The measured pH is compared with the desired pH. The current through the cell (1) is adjusted in response to the comparison in order to electrolyse the stream to the desired pH.

Title: Mats of Metallic Fibres, Apparatus for Manufacturing Such Mats, and Methods of Manufacturing Articles Incorporating Such Mats
IPC: D04H1/54
Filed: 1980-10-27
Abstract: A mat of metallic (e.g. steel) fibres comprises fibres which are either continuous or have a certain length within a range defined by the length/diameter ratio (L/d) 100 to 2000. The mat is held together by the length and surface structure of the fibres, and also by the application of a bonding agent. The mat has a variety of uses, mainly as a reinforcement in cement and concrete technology where it is of particular benefit in manufacturing thin, double-curved shells, and also in the reinforcement of rubber, plastics and other materials. A technique for manufacturing the mat utilises thin wire which is applied to a surface either continuously or as short fibres. The fibres may be distributed in a uniform or random manner in the mat. <IMAGE>

Patent GB-2092326-A (GB)
Title: Improvements in or relating to spectacle side arms and side plates therefor
IPC: G02C5/22
Filed: 1981-02-04
Abstract: A side plate (11) is mounted on a base or reinforcement (12) which latter is forced into the end of a side arm (not shown). This forcing in operation tends to roll up a part of the material of the side arm and this material has been found to clog the spaces between the charniers (15) and also the hinge screw apertures (17) of the charniers. The proposal of the invention avoids this possibility by arranging that the bases of the grooves (16) between the charniers (15) are located sufficiently above the level of the base to ensure that the rolled up material cannot enter the grooves (16). Additionally, the inclination of the charniers (15) with respect to the base block (14) is such as to avoid the possibility of the material passing alongside the outer face of the outermost charnier. <IMAGE>
