Title: Computer with programme tracing facility
IPC: G06F11/00
Filed: 1971-09-08
Abstract: 1356997 Digital calculators RCA CORPORATION 8 Sept 1971 [11 Sept 1970] 41795/71 Heading G4A A computer having a program counter PC and an instruction register IR is provided with apparatus controlled by the program to set a branch record flip-flop BR and to load a beginning address in a branch address counter BAC, and gates which are operative, when a branch instruction in IR specifies a branch which is to be taken, to transfer the contents of PC to the memory address specified by BAC and to increment BAC. In this way a record is made of all program branches which have been taken.  Operation.-A special instruction is included in the program to initiate recording of the branch instruction addresses, the OP code of this instruction being decoded at D to produce an output 29 for setting BR and loading the beginning address in BAC. When a branch instruction is subsequently read out from memory into IR its OP code provides an output 10 from D and a decision is made at C as to whether or not the branch is to be taken. If the branch conditions are not satisfied, the program counter PC is incremented. If the branch is to be taken, gate 30 is enabled (BR having been previously set). Gates 40 and 50 are enabled at t 2  to store the instruction address in PC at the beginning address held by BAC, BAC is incremented at t 3  by gate 34, and an all l's word is then gated from source 28 at t 4  to be stored at the incremented address in BAC (supplied via gates 44) to act as a marker identifying the location of the last branch instruction address recorded, e.g. for use in a program debugging routine. Gate 36 then initiates execution of the branch instruction by causing transfer of a new address to PC. If BR has not been set by the special instruction, gate 32 would initiate execution of the branch instruction at t 1 . A maximum count detector 26 examines the incremented count in BAC and initiates a program interrupt when the area reserved in the memory for the branch instruction addresses has been filled. The interrupt may cause transfer of the addresses to further storage for subsequent print-out and analysis. If at any time a program error is detected a debugging flag is set in the interrupt system, the resulting debugging routine analysing the stored branch instruction addresses to determine where  the program error exists.

Abstract: 1,104,501. Ratchet gearing. MINISTER OF TECHNOLOGY LONDON. 14 Oct., 1965 [15 Oct., 1964], No. 42174/64. Heading F2Q. [Also in Division B4] A ratchet-and-pawl type screwdriver has a handle 11 extending radially of the ratchet wheel 17 and the handle houses a plunger 19 which is operable to move into engagement with the ratchet wheel 17 to drive the latter with respect to the pawl for effecting additional drive to the driven member. The tubular handle is slotted longitudinally at 12 to form lugs which provide bearing support for a pin 16 carrying the ratchet wheel 17, the two ends of the pin being shaped as screwdriver blades 28, 29. Two pawls 20, 21 in the form of leaf springs for engagement with the ratchet wheel are riveted respectively to the handle 11 and to the plunger 19 which is normally held out of engagement with the ratchet-wheel by a spring 24. To tighten a normal right-handed screw, the blade 28 is engaged in the screw slot and the handle is oscillated about the axis 16. If the friction between the screw and the member into which it is being screwed does not exceed the spring-friction load of the pawl 20 and ratchetwheel 17, anticlockwise movement of the handle will result in the screw being unscrewed and, in these circumstances, the plunger 19 is depressed repeatedly whereupon the pawl 21 engages the teeth of the ratchet wheel one at a time and rotates the same.

Abstract: 432,252. Lubricating rotary compressors. OGILVIE, H., 38, St. Augustine's Road, Camden Square, London. Jan. 23, 1934, No. 166/35. Divided out of 432,215. [Class 12 (iii)] [See also Group XXVI] A rotary compressor 1 fed with cooling and sealing oil which is sprayed into the working space from the ends of the casing, is provided with valve means to prevent flooding of the compressor with oil, when the speed falls below a fixed minimum. A compressor, which may be of the type described in Specifications 379,712, and 406,051, [Group XXVI], delivers air and oil through a pipe 6 to a separator 7, the air passing a non- return valve 25 to a main 8, and the oil returning to the end chambers 4 of the compressor by way of a cooler 10 and filter 11. When the delivery pressure falls a piston 17 drops and closes a valve 14 to shut off the oil supply to the compressor. Through a pipe 24 pressure on a piston 22 is released and a valve 21 is raised to allow pressure in the separator 7 to fall. Non-return valves 25, 15, also close. Valve 21 may be dispensed with but where used it is held closed manually when the compressor is re-started, until the delivery pressure reaches a pre-determined value.

Abstract: 1,077,566. Television recording; slow- and stop-motion; back-spacing. NIPPON HOSO KYOKAI. Oct. 14, 1965 [Oct. 17, 1964], No. 43542/65. Heading G5R. A conventional television recorder 11 is associated with an auxiliary device (the righthand unit in the Figure) to play back recorded portions of the tape 6 either as " slow-motion " repeats or as a single " stop-action " frame with a minimum delay after the original recording. A loop-former 20a gathers up some 3 inches of tape (one second at five-to-one tape-speed reduction) to back-space the tape relative to a transverse-track head system 5H, which feeds one frame to a store means (Fig. 1, not shown) where the frame is recorded once and played back four times more before proceeding to record the next frame as detailed in Specification No. 39100/64. For stop action, the recorded frame is played back continuously. To reduce the time needed to run the tape up to synchronism with the heads 5H, a synchronously driven rotary head 24 reads back the frame pulses in the tape control track to time the re-engagement of the capstan and pinchroller 25, 26. A cue pulse, recorded at the time of originally recording the incident, controls the amount of back-spacing by the means 20a. A compensating resilient arm means 22 maintains tape-tension constant during backspacing and allows this small amount without driving the tape-spools 1, 8.

An instrument for biopsy comprises a tube to be inserted in an organ from which a sample of tissue is to be taken and a cutting wire carried by the tube, the wire being arranged to extend, or to be movable to a position on which it extends, close to the mouth of the tube and substantially diametrically across said mouth. The instrument shown in Fig. 1 comprises a tube 1 with an oblique sharp edge 10 with a wire 3, e.g. of stainless steel, extending through holes 2 to the fastening means 4. The embodiment illustrated in Fig. 2 involves moving the wire from an inoperative position (as in Fig. 2) to an operative position with the wire extending diametrically across the mouth of the tube. Outside tube 21 is an axially movable sleeve 23, the mouth edge 29 of which is oblique and provided with an outwardly bent lip 24 forming a support for cutting wire 25. When ready for operation, the cannula 22 (which facilitates insertion of the instrument into the sampling place) is removed, the sleeve 23 is moved (by rotation of a threaded member connecting tube and sleeve) so that its front edge registers with slot 26 in tube 21, into which the wire slips, and after tightening the wire by moving the sleeve 23 backwardly, the instrument is rotated 180‹ or more, thus cutting the sample of tissue free.

Abstract: In the solvent extraction of oils boiling in the range 250-600 DEG F. and having a 50% point less than 430 DEG  F. with furfural containing less than 0.5% wt. of water, solvent is removed from the raffinate by distilling in the absence of steam and in the presence of a hydrocarbon azeotrope former derived from the raffinate to recove hydrocarbon-furfural azeotrope overhead and solvent-free raffinate bottoms, and condensing the azeotrope which forms a solvent phase recycled to the extraction and a hydrocarbon phase used as the azeotrope former.  The extract phase is distilled in the presence of a higher boiling hydrocarbon so that furfural is recovered overhead leaving some solvent in the hydrocarbon bottoms.  The bottoms are stripped to recover extract which is subjected to an azeotropic distillation similar to the raffinate to remove remaining solvent.
