Title: Line concentrator
IPC: H04Q3/00
Filed: 1973-01-31
Abstract: 1393207 Automatic exchange systems SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 31 Jan 1973 [27 April 1972] 4872/73 Heading H4K An arrangement for coupling the active ones of 5 input lines to a smaller group of N output lines comprises an address generator G1 which generates cyclically the addresses of the S lines; an engagement unit A1 arranged to respond to said addresses, to scan 5 wires r<SP>1</SP>1 to r<SP>1</SP> s  which are associated individually with the input lines and carry engagement signals at least when the associated line becomes initially active, to select a free register of a ground of such registers RIC1-RICn when an engagement signal is detected and to enter in that register the address of the associated line; a cyclic scanner D 11  arranged to cyclically select the registers and to read out the contents of the registers to a decoder H; and a coupler AA arranged to respond to the register address from the scanner D 11  and time address from the decoder H and interconnect that line and an output, e.g. to a dial signal receiver RSA1 to RSAn, associated with that register. As described, the arrangement forms part of a concentrator and selectively connects S lines on to which calls have been concentrated to n registers during dialling. Detectors not shown individually associated with the lines mark corresponding wires r 1  to r 5  during dialling. These markings may be stored in storage elements M1 to MS reset by decoder H as soon as a register has been selected, or may be fed directly to the engagement unit a cyclic store being provided (Fig. 4, not shown), to store connections effected and prevent repeated allocation of registers to the same call. The coupler AA (Fig. 3, not shown), comprises a common line pair to which the input lines and dial signal receivers are coupled via transformers and diodes normally biased off but switchable to conduction by marking potentials applied to centre taps of the transformers. The subscribers may be equipped with multi-frequency dialling subsets and the dial signal receivers may code a digit detected and enter it in the associated register.

Abstract: 1,213,184. Road sweeping machines. J. H. ERIKSSON. 31 Jan., 1968 [29 March, 1967], No. 5093/68. Heading E1G. In a road-sweeping trailer comprising a power-driven brush 1 which is adjustably inclined to the direction of propulsion and so sweeps refuse into a roadside heap or strand to be collected by a further machine, dustladen air is extracted from the brush housing 4 by a fan 7 and is passed through a filter or, as shown, through a cyclone 8. The separated dust may be periodically collected from the cyclone container 10, or may be discharged to the road or roadside by a rotatable telescopic tube 11, either continuously, or periodically by a weight-loaded door 12. The brush and housing are carried by a U-member 2 pivoted to a lifting frame 3 connected to the draft vehicle, the brush being driven either by a power takeoff or by a separate motor. In a modification the housing 4 has wheels and is connected to the frame 2-3 by swinging links allowing relative vertical movement. In this construction the cyclone is replaced by a baffle-protected filter sleeve within the housing, compacted dust falling from the sleeve either on to the road ahead of the brush 1, or on to a screw conveyor discharging it to a container or to the roadside. For snow clearing the housing 4 and filter unit are removed.

Lawn-mowers. - Relates to motor-driven gang lawnmowers, and comprises an arrangement in which a " gang " of mower units of the rotary-cutter type are held in position by a gang frame situated beneath and flexibly connected to the vehicle frame for traction purposes, the gang frame being supported by the mower units, which are disposed in front and rear' rows flexibly connected, the mower units being individually and collectively free to follow undulations of the ground. The mower units are of the type comprising a rotary cutter 14 and a. wiper roller 13 mounted in a frame 12, the cutter being driven by the ground wheels 11, and are arranged in any convenient number in the manner shown, for example, in Fig. 3, the units being held in position by a flexible gang frame 20, 25, 27, and being adapted to rock about the running-axles 16 to follow the undulations of the ground. The gang frame is arranged beneath the vehicle or tractor frame 1 as shown in Fig. 1, being flexibly coupled thereto for traction purposes by a draft link or yoke 29. The 'gang frame comprises a front beam or bolster 27 carrying the draft-link 29 and supported by standards 28 on the running-axle 16 of the front mower unit; and also a rear main cross-beam 20 connected by cross-stays 19 to secondary beams or bolsters 15 supported by central standards 17 mounted on the running-axles of the rear mower units. The front and rear cross-beams 27, 20 are connected by a hook 26 or like universal coupling. The main cross-beam 20 carries depending posts 21 with additional braces 22, 23 serving to keep the unit frames 12 in rigid parallelism with the cross-beam, whilst permitting independent vertical tilting. Springs 44 between arms 45 on the frames 12 and brackets 46 on the gang frame keep the cutters against the ground.

Abstract: 972, 257. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 13, 1962 [March 31, 1961], No. 5552/62. Heading G4H. A byte-converter 10, Fig. 1 check circuit comprises a modulus 2 adder 52 for adding both parity bits associated with input bytes (these bits on a lead 26 not being passed to the byte converter) and parity bits generated, by a unit 14, on a lead 25, in respect of output bytes. The state of the modulus 2 adder at the end of a conversion cycle is then indicative of whether an error has occurred or not. The circuit described has the feature that either odd or even parity bits can be used in respect of both the input bytes and the output bytes, and the particular parities being used are indicated by one of leads 16a, 16b and one of leads 17a, 17b. This results in the opening of one of two gates 41, 42 for the input parity bits, and one of two gates 43, 44 for the output parity bits. Should a parity error be detected in an input byte, an indication of this is produced by means not shown, and also an extra bit is passed to the modulus 2 adder so that the operation of the byte-converter can still be checked.
