Abstract: 1414185 Dozer-bucket assembly ROME INDUSTRIES Inc 26 Oct 1972 [23 Nov 1971] 49397/72 Heading E1F An earth moving assembly comprises a bucket 30, a bulldozer blade 80, and a power operated linkage operable to move the blade from a position in which it forms a rear wall to the bucket (Fig. 4, not shown), through intermediate positions to function as an earth ejector, Fig. 5, to a bulldozer operating position, Fig. 6, in which the blade's leading edge is moved in front of and below the leading edge of the bucket and positively engages the bucket. The blade is joined to the top of the bucket by links 102 and is pushed forwards by the action of a hydraulic unit 150 acting on a crank arm 116 which is joined by links 113, 120, 121 to the bucket. The links 120, 121 are pivotally joined at 122 and are normally urged by spring 128 to the position shown in Fig. 5; but, as an abutment edge 95a on the blade slides over the bucket edge, a set screw 133 on the arm 116 causes relative movement of the links about 122. This has the effect of drawing the lower edge of the blade to the rear to positively engage portion 95 against the bucket edge. Fig. 7 shows a modification of the operating mechanism: the crank arm 116 directly engages a slot 182 in an arm 180 fixed to the blade, is normally urged to the top of the slot by spring 183, and slides down the slot drawing the blade to the rear for bulldozer operation. In a further modified control link arrangement (Figs. 8-12, not shown) screw threaded members are incorporated to allow adjustment of the position of top link axis 103, and of the length of the link 121.

IPC: B29C48/475
Filed: 1965-11-23
Abstract: 1,115,869. Blow-moulding; parison forming. MIDLAND-ROSS CORPORATION. 23 Nov., 1965, No. 49769/65. Heading B5A. In an extrusion blow-moulding process, the parison is formed of desired shape and wallthickness by applying a constant fluid pressure to a ram in the direction of extrusion by the ram, and resisting this applied pressure by a variable force as desired. In the embodiment shown, this is achieved by varying the speed of the downward stroke of accumulator ram (12, Fig; 1) which is operated hydraulically. As the ram 12 is lowered, the feeder arm (22) moves over the contoured, cam (22), causing valve (21) to increase or decrease the oil outlet flow, thereby increasing or decreasing the resistance to the downward movement of piston (20) in cylinder (10). Further fine control is obtained by the flow control (29) in a by-pass (28) around the valve (21). When the piston (12) reaches full downstroke, as in Fig. 1, oil returns to cylinder (10); through pipes (28, 15). via flow control (29), thus helping the upward stroke of piston (12), and further extrusion into accumulator chamber (16). Oil is prevented from returning via valve (21) by a non-return valve (26). Figs. 2-4 (not shown), show different parison shapes extruded using different cams.

Abstract: 1534710 Error detection HONEYWELL INFORMATION SYSTEMS Inc 17 Dec 1975 [17 Dec 1974] 51596/75 Heading G4A The operation of a data recovery unit 105 in a magnetic tape controller is tested by generating, in response to a recovery test routine stored in a microprogram memory 104-1, a predetermined sequence of signals which is fed to the data recovery unit 105, the resulting error signals being compared with the error signals which should be produced, as specified by the recovery test routine. The predetermined sequence of signals is arranged in blocks, corresponding to recorded blocks, and includes good data patterns, single channel failure data patterns and overskew data patterns in each of 9 channels, and data patterns which include all possible combinations of two channel failure tests, each such data pattern being generated for each of the operational speeds corresponding to different record and playback speeds. Each block includes preamble and postamble synchronizing signals, the number of preamble synchronizing signals in each block generated by the recovery test routine being less than in each recorded block. An index counter 104-16 is set from index register 104-14 and controls the frequency of operation of the tape controller. The tape controller normally connects a selected tape drive 204-1 to 204-8 to the central processing unit of a data processing system via an input/ output controller 200, an arithmetic and logic unit 104-2 and data recovery unit 105 for read operations or write buffer 109 for write operations. The data recovery unit 105 includes deskewing registers, clock circuits responsive to NRZ or phase encoded signals, and registers which indicate when signals are being received on the various channels. Prior to the running of the recovery test routine the steps set out at 400 to 412, Fig. 4, are carried out; substep (2) of step 404 involves checking the operations of register 104-5 and history address register 104-17 which stores a return branch address. Steps 406 to 412 carry out checks on the data recovery unit 105. In step 406 a pattern is produced to test unit 105, the pattern is modified to produce timing pulses of the form normally received from a tape drive, the error indications are checked and the output of the unit 105 is compared with the initially generated pattern. Step 408 causes a pseudo frame rate to be generated to test the drop frame indicator. Step 412 verifies circuits which select device speeds.
