Title: Run length coding communication apparatus
IPC: H04N1/413
Filed: 1973-12-05
Abstract: 1450789 Data transmission; facsimile systems; methods of coding INTERNATIONAL BUSINESS MACHINES CORP 5 Dec 1973 [11 Dec 1972] 56360/73 Headings H4P and H4F A bit stream in which there are successions of digits of each type, e.g. as in a facsimile system, are divided into (normally non-equal) groups of like type, digits between each transition being counted and counts being transmitted in the form of coded words of different fixed lengths for each type; each coded word may be a plurality of linked words of fixed length. A document to be copied is placed on a planar scanner illuminated on one side and a matrix of photo-sensors on the other which are scanned in controlled columnar sequence. Alternatively all bits may be written simultaneously into a memory which is subsequently scanned and runs of "black" or "white" bit representations are counted between transitions to other bit type. Conveniently a sync. point is established at the end of each scan line, or intermediately. Information is received by register 12 and clocked out by 15 with transitions detected by 13 which specifies colour on line 24 hence control unit 14 may enable background colour counter 18 which operates with word counter 17 if linked codes comprising one or more group digits are used. Alternatively "black" counter 19 will be enabled and when counter 19 reaches full count, a signal is placed on line 42 requesting a transfer code and content of 19 will be dumped into buffer 20 and transmitted. Types of codes are described in the specification, e.g. 4 bit for white background and 2 bit for black. At the receiver, incoming data passes through apparatus in reverse order to produce a copy of the original sequence which is placed in a print buffer 72 (see Figs. 1 and 5b, not shown) until an end of line or scan signal is detected when a line of bits is released to a print head (102) of a drum printer (96). The receiver clock (71) is not synchronized with the transmitter; the transmission rate is slower than the decoding rate hence the receiver input buffer (61) may at times be empty.

Abstract: 1,217,109. Tractor hitches. ALLISCHALMERS MFG. CO. 19 Nov., 1969 [22 Nov., 1968], No. 56578/69. Heading A1P. A power operated hitch comprises a hitch adapter 7 mounted on a three point linkage, the top link 4 of which may be a double acting ram and the lower links of which are raised and lowered via manual control of a motor, e.g. a ram 16. The hitch adapter 7 comprises an arcuate frame 19 with two hooks 23 at its lower free ends and an upper hook 20 adjacent a lug to which the upper link 4 is connected via a pin 8. In operation to connect the implement the hitch is put into its lower position by operation of a valve 35 controlling the ram 16 and the upper link 4 is extended by operation of a valve 34. The tractor is then backed up until the point of the hook 20 moves underneath a cross-pin 30 of a mast 26 of the implement. The ram 16 is then extended raising the draft arms 10 and the upper link 4 may be retracted. These movements will cause lifting of the hook 20 in turn lifting the front end of the implement and drawing it forward to a point adjacent the hitch adapter 7. The hitch is then lowered slightly by means of the ram 16 and the tractor backed until the lower hooks 23 are positioned below the cross-bars 28. The draft arms are then raised causing the implement to be latched and locked by means of the manually releasable latch 24. With the rams in the operating position an indicator (40), Fig. 2 (not shown), and a scale (41) indicate the operating position. Automatic control then operates according to the rotation of a torsion bar 50<SP>1</SP> caused by load on the draft links 10. This rotation is communicated via a linkwork 42 to the hydraulic system controlling the pressure in the actuator 16. Control through the valves 34 and 35 also provides for a lift position to raise the implement for the travel position and for weight transfer. The power systems involved may be electrical, Fig. 3 (not shown), or the power actuators may be mechanical, Fig. 6 (not shown).

IPC: D01H5/26
Abstract: 740,082. Fibre drafting apparatus. SACOLOWELL SHOPS. June 6, 1952 [June 11, 1951], No. 14382/52. Class 120 (2). Drafting mechanism of the kind in which an upper roller rests on a lower apron as it passes between a supporting roller and a bar has a positively driven apron driving roller outside the apron loop and partly encircled by the apron immediately in advance of the rearward portion of the loop to form a driving nip with the supporting roller. The apron 12 is tensioned by a roller 22 from which it passes to the driving roller 20 and round the supporting roller 14 to the bar 16. Upper roller 18 is pressed on to the apron 12 by a leafspring 48 that is secured to a slide 30 by one end and has its other end pressed upon the outer race of a ball bearing applied to an end of the roller 18, another spring 48 (not shown), pressing upon a bearing at its other end. Under normal conditions the springs 48 press the bearings of the roller 18 against the support for the bar 16 and the bearings of the roller 14 so that a clamping nip is not provided between the rollers 14, 18 and single-zone drafting between rollers 3, 4 and 5, 6 is effected. If desired, however, a clainping nip may be arranged so that draft takes place between the rollers 3, 4 and 14, 18. Pressure from the springs 48 causes a firm nip between the roller 14 and the driving roller 20. The roller 20 extends throughout the length of the machine, but the rollers 14, 18 are arranged in short sections, preferably to operate upon four slivers. Each section is positively driven and the sections may readily be removed from the machine in association with the corresponding apron bars and aprons. A peripheral speed 3 to 6 per cent greater than the speed of roller 14 is preferred for the roller 18, the bosses 19 of which may be of a resilient composition, such as natural or synthetic rubber of a durometer hardness of 50 to 100, or may be of smooth steel, or may be formed as porcupine rollers. Three slides 28, 30, 32 are mounted to be adjustable along a track 25 and carry the roller 6, rollers 14, 20 and the apron bar 16. An arm 15 loaded by a spring 17 applies pressure to the rollers 3, 5 through a fulcrum 11 and a weighting bar 7. The bearings of the rollers 14, 18 may be of an antifriction type, or may be of nylon or sintered metal. Specifications 524,666, 663,573, 668,880 and 672,728 are referred to.
