Abstract: 533,146. Magnetic sound recording apparatus. LIGUORI, G. April 11, 1939, No. 10995. Convention date, April 7, 1938. [Class 40 (ii)] Relates to magnetic sound recording apparatus comprising a reel carrier having a radially slidable member held inwards against a spring by the wire wound thereon and adapted when the wire supply on the reel is almost exhausted to be moved outwards by the spring to cause the stopping of the apparatus. According to the invention, a plunger 55 is arranged on a fixed part of the apparatus adjacent the reel 39 in such a position that when the spring controlled slide 50 carried by the reel moves outwards, it reaches the plunger and depresses it and thereby operates means not shown for stopping the apparatus, for example through a bell-crank lever 57 pivoted at 58. The slide 50 shown has a lug 51 projecting into a slot in the hollow hub 41 of the reel around which the wire is wound, the hollow 40 preventing jamming of the reel on its spindle under the tension of the wire. The Specification as open to inspection under Sect. 91 describes also reels driven by a differential gear and provided with a free-wheellike ball clutch, Fig. 1 (Cancelled, not shown), and a helical-slot drive device for reciprocating the sound head, Figs. 2 and 3 (Cancelled, not shown).

Title: Data processing system with compare instruction
IPC: G06F7/02
Filed: 1974-12-12
Abstract: 1494506 Data processing HONEYWELL INFORMATION SYSTEMS Inc 12 Dec 1974 [13 Dec 1973] 53775/74 Addition to 1494505 Heading G4A In a data processing system in which each data field has an associated data field descriptor defining the format of the data when an instruction for comparing data fields is effected, the data descriptors are compared and if they are different the data in one of the fields is reformatted before the data of the field is compared. Data processing system.-The system comprises four semi-conductor memory modules (201, Fig. 2, not shown) interfaced via a sequencer (202) to an input/output controller (220) controlling, e.g. tape or disc stores and a CPU (200) the latter including a read only micro program store (210), a data management unit (206), an address control unit (207) and an ALU (212). A buffer (204) stores the most recently or most frequently used data in the form of pages, a directory (205) keeping an index of pages in the store (204), address control unit (207) including an associative store with the base addresses of the most recently used memory segments and their segment number. Compare operation.-The descriptors specified by the address syllables in the two words of a compare instruction are fetched (using the address (segment number and offset) in a base register specified by the address syllable together with the displacement field in the address syllable) and stored in registers 408, 410 (Fig. 4). The length of the data represented by bits 56-63 of the descriptors is then checked to ensure that it is non zero. The type of the data (represented by bits 40-47) is next examined and if both operands and in decimal code, packed or unpacked, a check is made that the operands have no 4 bit numbers greater than 9. The data types of the two descriptors are compared by subtraction and if they are equal but the lengths are not equal the shorter oper- and is extended to the left with zeros and two operands are then compared. If the first data type coding number is less than the second (indicating that the former is unpacked decimal) the first data field is reformatted to packed decimal before comparison. Otherwise the second data field is reformatted. If the coding is alphanumeric the shorter data is extended to the right by blanks if the lengths are dfferent and the operands are then compared, byte by byte with the length field being decremented at each comparison until either of the lengths are zero or non comparison occurs. In the ease of either decimal or alpha numeric coding, if equality is found a condition code of 3 is set in a status register 418, the register 418 being set to 1 if the first operand is the larger or 2 if the second operand is the larger.

Title: Stacking Apparatus
Inventor: BERRYMAN GORDON JOHN VICTOR
IPC: B65G57/03
Filed: 1966-12-01
Abstract: 1,154,218. Stacking articles. HARRIS-ECONOMY Ltd. 27 Nov., 1967 [1 Dec., 1966], No. 53777/66. Heading B8C. Apparatus for stacking articles in a plurality of horizontal layers includes endless conveyer means, means for changing the orientation of selected articles on the conveyer means, means for collecting a required number of articles on the conveyer means to provide a layer of articles, and means to transfer said layer of articles from the conveyer means on to a stacking support, the stacking support being adapted to move intermittently downwards in increments generally corresponding to the height of the particular layer of articles. In the apparatus shown ingots from a continuous casting machine are fed into a shoot 6 and thence to a conveyer belt 11. Selected ingots are turned over by a turning device 7, and a sensing device 12 and a stop device 13 control the feed of ingots forward to a turning device 16 by means of which selected ingots are rotated through 90 degrees by a rotating head 17 having gripping fingers 18, 19. A memory means actuated by sensing device 12 counts the ingots and causes the turning device 16 to operate on pre-selected pairs of ingots as required by the stack being formed. The ingots are thus fed in a preselected arrangement to transfer station 23 where they form a horizontal layer ready for transfer to stacking station 30. Once the required number of ingots are at the transfer station a stop 40 is operated. The transfer means consists of a ram operated pusher 27 which pushes the ingots off the belt 11 on to a plate 29 supported beneath the pusher plate 27, on the outward stroke of the ram. On the return stroke of the ram pawls 34 prevent withdrawal of the ingots with the plate 29 so that the ingots drop on to two fork bars 31 mounted on an hydraulic lift mechanism 32 forming the stacking means. A pivoted gate 35 is provided for assisting the positioning of the first layer of ingots on the bars 31. For each subsequent layer of ingots the lift mechanism is lowered the required distance and when the required stack is formed the whole stack is lowered on to the conveyer 38 and moved to a position for removal by a fork-lift truck. The stack shown in Fig. 1 comprises a bottom layer of four large ingots 1 longitudinally oriented, a next layer of smaller ingots 2 oriented so that there is a single ingot across each end with two longitudinally oriented ingots in the middle. The third layer is of similar formation to the first and the fourth of the second, and so on alternately upwards through the stack. The top layer is arranged similarly to the first layer except that all four ingots have been turned over.

Abstract: 1326394 Fluid-pressure servomotor systems FUJITSU Ltd 17 Nov 1970 [19 Nov 1969 (2)] 54575/70 Heading G3P [Also in Division F2] The speed of a hydraulic motor 13 e.g. in a machine tool control system, is regulated by a spool valve 1 driven by an electric pulse motor 12 Axial control movement of the spool is effected by a screw and nut connection 15, 17 between the spool and the motor shaft which automatically feeds back any error. With the object of shortening the overall length of the valve and the time needed to attain full opening, and to render the fabrication of the valve less troublesome, control ports in a sleeve 3 in which the spool slides, are formed with an initial opening portion a which is of narrow rectangular shape corresponding to a linear characteristic. The remaining portions b of these ports are of relatively wide form, such as circular. As shown, the  sleeve is fabricated in separate axial sections 31 to 35.
