Title: Improvements in and relating to Telephone Signal Transmission System
IPC: H04B3/20
Filed: 1967-02-03
Abstract: 1,181,123. TASI system. SOC. ITALIANA TELECOMUNICAZIONI SIEMENS S.p.A. 3 Feb., 1967 [5 May, 1966], No. 5305/67. Heading H4R. In a TASI system the received speech sample is compared with the signal to be transmitted and the transmission is inhibited if the signal to be transmitted is considered to be an echo of the received signal. Fig. 1 shows one subscriber's line circuit of the TASI system of Specification 1,078,483 in which a memory circuit MTi controls a counting stage in the counter DT to permit sampling of active lines, the memory circuit normally being set at the commencement of a sampling cycle to prevent sampling of a line, and reset, by a reset pulse r, if the line is determined to be active. The state of the line is determined by comparing, in amplifier #, the signal levels in the incoming line f and the outgoing line C, and enabling a gate P3 when the signal on line C exceeds that on line f, as monitored by the circuits Ili and I2i. Enabling gate P3 passes the signal level on outgoing line C to a threshold device SG which, if the signal is above circuit noise level enables CTi to allow reset pulse r to reset memory MTi and allow sampling of that subscriber on the following sampling cycle. During data reception it may be required to transmit low level acknowledge signals in the presence of high level incoming data signals. In this event a long time constant integrator circuit I2i is arranged to disable the signal input to the comparator amplifier # from the receive line f when a high level signal of long duration, such as a data signal, occurs. The speech signals are normally transmitted via an integrator circuit Ili of comparatively short time constant.

Title: Improvements in or relating to pneumatic tires
IPC: B60B21/10
Filed: 1953-10-19
Abstract: 754,204. Pneumatic tyres. FIRESTONE TIRE & RUBBER CO. Oct. 19,1953 [Feb. 16, 1953], No. 5406/55. Divided out of 754,122. Class 144 (2). A pneumatic tyre for use with the wheel rim described in Specification 754,122 is formed with the radially inner surface of each bead 17 sloped radially and axially outwards without interruption at an angle between 12 and 20 degrees to the tyre axis. This reduces the bead size and provides for greater flexibility. Fig. 10 shows such a tyre 11 on a suitable rim 12 with a conventional tyre and rim assembly shown in dot and dash lines. The tyre beads may be formed as shown in Fig. 11, each with two spaced bead cores 37, 38, the axially outer core 38 being of greater diameter than the inner core 37. This provides for a reduction in the number of plies wrapped therearound. The slope of the bead surfaces may be greater than that of the corresponding rim surfaces so that the bead toes are compressed more than the bead heels when the tyre is mounted on the rim.

Title: Improved apparatus for trimming hedges
IPC: A01G3/04
Filed: 1943-04-07
Abstract: 564,073. Hedge cutters. McDOWALL, A. April 7,1943, No. 5568. [Class 6 (ii)] Hedge-trimming apparatus comprises a rotary cutter 11 mounted on the shaft of an electric motor 13 suspended from a beam adjustably supported on a vehicle, or a base carried on a vehicle. For effecting vertical reciprocation the flexible suspension means 14 is connected to a motor 30 through gearing 33 for converting rotary into reciprocating motion, toothed wheels 28, 27 and a crank-pin on a disc 24 coaxial with the wheel 27. Also from the gearing 33 is driven a pinion 32 meshing with a quadrant on the standard 16, whereby horizontal reciprocations are imparted to the motor 13. Hydraulically operated mechanism may replace the motor 30.. In a modification, Fig. 2, the supporting beam 39 is slidably mounted in the top of the frame 40. A motor 46 imparts movement to a chain 47 and thence to a pair of flexible supports 44, 45. Tilting of the motor 13 and cutter 11, particularly during the upper part of its vertical movement to round off the top edge of the hedge, is caused by connecting the cord 45 to the longer arm 50 of a bell-crank. The shorter arm 51 has a bifurcated end working between stops 54 on the chain 47. Horizontal reciprocating movement of the beam 39 is produced by a drum 59 on the motor shaft, on which drum is wound the end of a cord 60 connected at the further end to a tension spring 64 which returns the beam to the initial position. Automatic periodic reversal of the motor is effected by a reversing switch 75 operated by stops 76 fixed to the chain 47. Alternatively, a unidirectional motor may be used, working through mechanical reversing gear. A handle 36 may be carried and serves both to steady the motor movements or to make slight positional adjustments thereof.

Abstract: 569,378. Motor - vehicle frames. VANNECK, V. P. BOURNE-. April 14, 1943, No. 5975. [Class 79 (iv)] [Also in Group XXXII] A vehicle body mounting or subframe, applicable particularly to vehicles having tipping bodies, is fabricated from tubular or boxsection longitudinals and from cross-members rolled, pressed or stamped from sheet material, with integral stiffening or reinforcement, all of steel or preferably of light alloy such as aluminium or magnesium alloy and welded together to constitute a unitary sub-structure for the body, a sheet metal body floor being secured by welding to the upper edges of the cross-members 30 as to form an integral part of the substructure for its further reinforcement. As shown, the frame for a tipping body comprises three tubular longitudinals 1, 2, 3 bridged between end cross-members 8, by four channelsection cross-members 4, 5, 6, 7 each perforated to pass the longitudinals, the components being welded at the junctions 9. Additional channelsection longitudinals 10, 11 associated with the side longitudinals 2, 3 may reinforce the frame particularly where it rests on the main chassis members 12, and diagonal braces may also be incorporated. The body floor 13 is welded on the upper flanges 14 of the cross-members and may carry uprights, side walls, and a hinged tail door. Hinge plates 16 associated or integral with the rear cross-member 4 constitute brackets for the near pivots and in the case of side tippers and three-way tippers corresponding brackets are furnished for the pivots at the front of the body. When applied to platform vehicles, the frame may also constitute the chassis and be continued beyond the body to mount the engine and cab. There may be only two longitudinals threaded through three or four cross-members which may be corrugated, &c. for stiffening between their upper and lower edges. A pressure plate for a hydraulic ram or hoist may be welded to the lower edges of the cross-members or immediately beneath the lower face of the body floor.

Abstract: 1,137,988. Corrugating. SOC. NOUVELLE SPIDEM. 8 Feb., 1967 [9 Feb., 1966], No. 5997/67. Heading B3E. A machine for profiling strip metal comprises a pair of parallel shafts constituted by two spindles 19, a sleeve 15, and shaping rollers 16a, 16b, 16c. The spindle is mounted in roller bearings 10, 10a at each end and one bearing housing 1 is fixed and the other housing 2 pivotally connected to the fixed housing so that the gap between the rollers can be adjusted by a screw 4 having opposite or differential threads. The spacing between the rollers is set by a key (7), Fig. 3b (not shown), which is positioned between nuts on the housings. A separate key is provided for each set of rollers. In one embodiment the left-hand side of the upper shaft has a sleeve 12 to which a toothed driving wheel 23 is fixed. The right-hand side of the lower shaft has a similar sleeve 12a and driving wheel. Each roller consists of an integral shaped roller or a series of rollers of different shapes held together by lock-nuts 17, 17a. A support is provided on each bearing housing for centring the sleeve 15 during assembly. The support is pivoted into position about a pivot 21 and held in position by a pin 22. In a similar embodiment the drive wheels are provided at only one side of the pair of shafts. The toothed wheels of the upper shaft also permit declutching so that the drive of the rollers is obtained only from the metal strip. The toothed wheels (25), (26), Fig. 2 (not shown), are normally held fast with each other by a chain (24a). In a further embodiment the driving wheels 23 are mounted on hubs (28) around the end sleeves and a flange (28a) on each hub is engaged with a flange (29) on the sleeve by a pin (35). The flanges on the sleeves are engaged with the central sleeve by dowel pins (33), (33a). To disengage the drive in this embodiment the pins (35) are removed. In an alternative embodiment, Fig. 4a (not shown), the drive between the flanges is achieved by a friction ring (38) and a metal ring (39) on the flanges (29), (28a) respectively. The pressure between the rings is adjustable by a screw (41).
