Abstract: 1,110,051. Making nets: making non woven net-like fabrics: film extrusion dies: making reticulated films. T. J. SMITH & NEPHEW Ltd. 21 Dec., 1964 [25 Sept., 1963], No. 37808/63. Headings B5A and B5B. Net-like plastic material is formed by grooving a sheet 45 on both sides so that, at the cross over points 50 of the grooves 46, 47, the sheet is drastically reduced in thickness. The grooved sheet is then biaxially stressed or stretched, first in one direction (see Figs. 15-17, not shown), so as to cold draw the parts of reduced thickness into a fibrous state 52, and then in a direction at right angles, so as to split the sheet in the region of the fibre, and to distort the splits into shaped holes (see Figs. 19 and 20, not shown). The grooved sheet may be formed between helically or otherwise grooved rollers (Fig. 2, not shown), by extrusion through an annular die comprising inner and outer relatively rotatable rings 33, 34, having groove forming ridges 35, 36 (see Figs. 6 and 7, not shown), or by extrusion between two linearly reciprocable ridged die plates 42, 43, (see Fig. 9, not shown).

Title: Pressure cylinder type measuring apparatus
IPC: G01G5/00
Filed: 1965-09-07
Abstract: 1,072,302. Dynamometers. HARWOOD ENGINEERING CO. Sept. 7, 1965 [Sept. 11, 1964], No.38232/65. Heading G1W. In apparatus for balancing a force applied to a load coupler 62 by the hydraulic pressure of a lubricant supplied under pressure through an inlet port 53 and the bore 54 in a plug 50 to the underside of a piston 48 in a cylinder 28 rotatable on a bushing 30, fluid is also supplied at controlled pressures to a cavity 44 between the cylinder 28 and a jacket 32 to contract the cylinder 28 radially to maintain a leakage fit clearance between it and each of the piston 48 and plug 50. The pressure on the top of the plug 50 exceeds that on its reduced base and ensures a good seal between the plug 50 and base to close the bottom of the cylinder. A pressure gauge in the supply line to the inlet port 53 indicates the value of the force measured. Any tendency of the cylinder 28 to tilt is prevented by centrally locating the load coupler 62 by means of a rubber ring 74 and centering its rockered bottom face 63 against the flat top of the piston 48 which is itself centred by the even distribution of the lubricant in the annular groove 61. A motor-driven cam oscillates a rod 120 fixed in the cylinder assembly 28, 32 to prevent any tendency of the piston 48 to stick in the cylinder 28. In the modification of Fig. 4 (not shown) the bottom closure of the cylinder 28 is sealed by a sealing ring round the plug 50 which frictionally prevents rotation of the cylinder, but sticking can be prevented by tangentially vibrating the cylinder at ultrasonic frequency.

Title: Improvements relating to electric selecting arrangements
Inventor: WARMAN BLOOMFIELD JAMES
IPC: H04Q3/00
Filed: 1960-07-18
Abstract: 989,338. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 3, 1961 [July 18, 1960], No. 38388/62. Divided out of 989,336. Heading H4K. In an arrangement for selecting a free circuit from a number of such circuits in a given order of priority, a bi-stable circuit associated with each circuit is set to one or other of its states in accordance with the free or busy condition; and each circuit has a gate circuit associated therewith connected to the outputs of the bistable circuits in such a way that it is enabled only if its associated bi-stable circuit is set to the free condition and all the bi-stable circuits associated with higher order priority circuits are set to the busy condition. The invention is described with reference to the selection of a pair of connecting switches capable of completing a connection between a calling and a called line as described in Specification 989,336. For each connecting switch on the calling side which is busy, an associated one of terminals ttg1 ... ttg5 is marked thereby causing corresponding ones of the bi-stable circuits LSGe1 ... LSGe5 to be set, thereby causing terminals such as AB, AF to assume - ve and earth potentials when the connector is busy and vice versa when the connector is free. The output terminals AB, AF ... EB, EF are connected to gates GCGA ... GCGE so arranged that in each gate except that corresponding to a free connector of highest priority one of the rectifiers is conducting thereby maintaining the associated transistor TrGCA ... E conducting. In the exceptional case the associated transistor, say TrGCA, is cut off thereby applying negative potential to a combination of leads lrg to indicate in binary form the selected connector. A similar arrangement operates for selecting the called side connector. In order to prevent an attempt to use the same connector for connection to both calling and called line, outputs such as that from transistor TrGCA on the calling side are arranged to operate via transistor Trs1 (enabled by a condition on lead lg/ld indicating that the calling and called lines are served by the same group of connector switches) to override the output of the corresponding bi-stable circuit LSDe1 on the called side to cause busy conditions to emerge from terminals AB, AF on the called side. In order to provide a more even distribution of traffic over the switches, a second set of gates GCGA<SP>1</SP> ... GCGE<SP>1</SP> is arranged to effect choice in the reverse order of priority, similar arrangements being provided on the called side. The alternative sets of gates are switched in alternately, under control of a bi-stable circuit GOe whose state is changed over on the initiation of each call. If no connectors are free gates GBG or GBD give a busy condition on leads blc or bld. The Speci. fication also describes the priority selecting arrangements relating to PBX outlets, which arrangements are described more fully in Specification 989,340.

The recess 39 can be closed by a bar 43.  The implement is attached to the tractor by means of the beam 21 which is rotatably mounted on the shaft 31 by means of two pairs of rollers (29), Fig. 4 (not shown), the connection beam also being free to move vertically on the shaft. A wheel 10 is provided under each rake head, and can be set in 3 different positions relative to the rake head by means of sockets (16) and locking pins (17), Fig. 1 (not shown). When the lifting device is in its lowered position, the locating pin 37 is free to move between edges 40 and 41, allowing some relative rotation when the implement is operating. When the lifting device is raised, however, the pin 37 abuts against the lower corner of recess 38 owing to the weight of the implement, and is therefore locked in position.  A second recess 39 allows a second locked transport position, and is normally closed by the bar 43, hinged at 42, which is liftable by means of a rope 50, which may be pulled from the driver's seat. The crank 25, which enables the angle of tilt of the rake heads to be varied, passes through a sleeve turnably supported by trunnion pins 26 and though a block turnably supported by trunnion pins 28.

As shown, the saw blade 1 is secured to a blade-holder 2 turnably arranged, in the plane of the blade 1, on the main body 5, the return spring 3 serving to cushion saw kick-back. The detent 4 comprises a spring loaded ball arranged between the body 5 and blade-holder 2 and normally serving as an index point to maintain the blade 1 in its correct working position relative the body 5. The saw blade 1 may be mounted on the body 5 by a universal-joint mechanism (not shown) permitting other relative movements of the saw blade in addition to the turnable movement whereby forces generated during saw kickback are not transmitted directly to the body 5. Additionally the chain-saw power-operating unit, e.g. I.C. engine (not shown) may be automatically de-activated when relative movement between the blade 1 and body 5 exceeds a predetermined amount. Where a damper is used between the relatively movable blade 1 and body 5, this may be connected between the I.C. engine and said relatively movable blade and body and utilize the gas pressure of the I.C. engine. Further shock cushioning and damping devices including shoe and band brakes (all not shown), arranged between the relatively movable blade and body, are briefly described.
