Patent GB-1156279-A (GB)
Title: Data Transmission Terminal
Inventor: WATERS DEREK BRIAN
IPC: H04L25/48
Filed: 1967-12-20
Abstract: 1,156,279. Digital transmission systems; automatic phase control; multiplex pulse code signalling. STANDARD TELEPHONES & CABLES Ltd. 20 Dec., 1967, No. 57880/67. Headings H3A, H4L and H4P. Binary data is translated to ternary low disparity code prior to transmission. Each 4-bit data group is converted to a corresponding zero or positive disparity 3-digit ternary group. The cumulative disparity of the transmitted ternary groups is determined and when this is positive the next positive disparity group is inverted prior to transmission. At the receiver the data is reconverted to binary form, the sense of the disparity being of no significance. Transmitter, Fig. 2 and Fig. 3 (not shown).- Serial binary data is staticized in shift register 200, each parallel 4-bit group passing via store 201 to translator 203 comprising gates. Parallel 3-digit ternary data is serialized at 204 and passes via inverter 205 to the transmitter output and also to unit 208 which includes an integrator which records the total disparity. If the disparity is positive the next positive disparity ternary group is inverted by enabling inverter 205. The inverter and unit 208 are inhibited whenever a zero disparity group is generated by the translator. The various units are controlled by timing pulses derived from a bit-rate clock source feeding counter divider 202 whose output feeds tuned multiplier 207. In a modification, Fig. 7 (not shown), the translator outputs 4-digit groups, one digit being zero, so that the serializer (704) can operate at the input bit rate. The inverter then feeds a unit which changes the digit rate to threequarters the bit rate prior to transmission. Receiver, Fig. 5 and Fig. 6 (not shown).-The ternary data is converted to parallel form at 500 and passed to translator 501 which converts the data to the corresponding 4-bit group. The binary data is stored at 503, serialized at 504, and passed to the receiver output. Digit rate clock pulses control the circuitry via counter divider 502 and tuned multiplier 505. Synchronizing.-During transmission, the ternary group 000 occurs once in each 1000 groups. When a group 000 is detected in the input staticizer 500 a monostable unit is triggered and generates a signal having a 1:1 mark: space ratio if the rate of occurrence of the groups is 1 in 1000. The monostable feeds an integrator, and if that rate of occurrence is exceeded the integrator output causes a pulse to be generated which blanks one of the digitrate clock pulses being fed to the staticizer 500 and to divider 502, thereby adjusting the phase. Multiplexing, Fig. 9 (not shown).-By translating from binary to ternary code a 24-channel binary PCM input occupies only part of the bandwidth of the transmission channel that would be needed to transmit the PCM in binary form. The unused part of the channel may therefore be used for additional data or speech channels.

Abstract: 1423159 Shovels SPEAR & JACKSON (TOOLS) Ltd 21 March 1973 [19 Dec 1972] 58491/72 Heading A1B [Also in Division B4] A folding shovel comprises a tubular shaft 10 which is open at one end and has a hilt at its other end, a shovel blade 20 having a hollow open-ended shank 18, and a yielding connection between the shaft and the hollow shank which urges them into a position where their open ends abut and surround a tube 42 joined to and projecting from the open end of either the shaft or the shank, the said yielding connection being formed by a tension spring 24 which is anchored to and lies mainly or entirely within the hollow shank of the blade, and a chain or other flexible linkage 16 which lies mainly or entirely within the tubular shaft so that the hollow shank and the tubular shaft can be pulled apart, without breaking the yielding connection between them, and laid or folded one against the other as shown in Fig. 4. As shown the tubular handle shaft 10 has a second spring 22, the two springs being connected by a short length of chain 38 and the shaft 10 has a tubular sleeve 42 welded in its open end which fits snugly into the upper mouth portion of the blade shank 18. The handle 12 of the shovel may be e.g. of polypropylene and the shaft 10 which may be of steel or aluminium alloy may be covered externally with a thin adhering sleeve of e.g. PVC.

Abstract: 1452308 Mounting for a rotary mower MASSEY-FERGUSON-PERKINS Ltd 19 Dec 1973 [6 Jan 1973] 58750/73 Divided out of 1451896 Headings AIF and A1P A rotary mower is supported from below by a ground engaging draught bar 98 which is pivotally connected to a drag bar 50 so that the cutting elements i.e. rotors 12, 14 are offset to one side of the tractor. The end of the drag bar remote from the mower is pivoted to an L shaped support member 42 which has one limb journalled in an upright tube 46, the tube forming part of a rigid frame 40 which in use is connected to the tractor hitch. Drive is taken from the tractor p.t.o. shaft, through a main gearbox 78 and shaft 86 which together with universal joints 82, 84 forms a connection between the main gearbox 78, and a secondary gearbox 58 mounted above the inside rotor 12, a shaft 88 and a third gearbox 90 mounted above and driving the outside rotor 14. A frame incorporating a member 54 and a bar 56 pivotally attached to its upper end connects between the inner end of the draught bar 98 and the secondary gearbox 58, forms a rigid unit with rotor 12. The frame member 54 is connected to the top of frame 40 by a bar 64 having a slot 72 cooperating with a pin 68 to take up lost motion. A break-back mechanism 96 connected between frame 40 and drag bar 50 holds the mower in its operating position; if an obstruction is encountered the break-back releases the mower which then swings rearward about the axis of tube 46. To raise the mower clear of the ground, frame 40 is raised by the tractor hitch, the drag bar 50 pivots about its link 52 with the draught bar until a stop 94 at the end of the drag bar abuts frame member 54, after which the mower is lifted clear of the ground. Movement to the transport position is effected by disengaging the break-back, the mower is then manually swung rearward into the longitudinal axis of the tractor, end 48 of L tube 42 then engages a catch 122 holding the mower in this position. A parking stand 110 is lowered to the ground to support the mower when it is disconnected from the tractor.

Title: Improvements in fluid amplifier
Inventor: O'KEEFE ROBERT FRANCIS
IPC: F15C1/18
Filed: 1966-03-24
Abstract: 1,148,658. Pure fluid amplifiers. PITNEYBOWES Inc. March 24, 1966, No.60727/68. Divided out of 1,148, 657. Heading G3H. A turbulence amplifier comprises an emitter connected to a fluid source 14 and a receiver connected to an actuator 31. The emitter has a passage 13, providing a laminar flow, a chamber 16 and output orifice 20. A control signal duct 32 opens into the chamber 16 and is connected to a Venturi 35. With no flow through the Venturi, flow through the emitter induces flow through the signal duct 32 to cause a turbulent flow in the emitter and thus a low pressure in the collector. With flow through the Venturi, induced flow is prevented and the main stream remains laminar to provide a high pressure output in the collector. The outlet orifice 20 of the emitter opens into a flared chamber leading to exhaust ports 21, 22, the wall 18 of the chamber prevents sound waves from interfering with the laminar flow.
