Abstract: 1,197,186. Cargo vessels; propelling. NATIONAL RESEARCH DEVELOPMENT CORP. 23 Aug., 1967 [23 Aug., 1966], No. 37806/66. Heading B7V. A marine vessel has a cargo-carrying unit 2 and a detachable motive-unit 1 with a bow 6 shaped to mate with a matching stern on the unit 2 and so couple the units together below the water-line, coupling means 26 being also provided at deck level. A transverse rib (20), Fig. 5 (not shown), on the stern of the unit 2 engages with a recess (13), Fig. 3 (not shown), in the bow 6. The means 26 includes plates (71), Figs. 13 and 14 (not shown), attached to links, or "straps" (72) pivotally connected to the bow 6 and connectable by pins (76) to the unit 2, said plates extending between the units when the latter are coupled together and acting as a breakwater for the unit 1 when the latter is disconnected. The straps are aided by tensile members (82) therebetween. In another embodiment, Figs. 7 and 8, the motive unit 30 has a recess 32 that engages with a tongue 53 at the stern of the cargo-carrying unit 31, fenders 44, 51 being provided at deck level as shown. The fenders 44 may engage with either a surface 45 or bearer members 47 on the unit 31. A ballast tank 34 facilitates engagement, or disengagement, of the recess and tongue aforesaid. Links 56 connect the units to each other at deck level and are pivotable about pins 57 by a derrick 69. The links and hydraulic rams to adjust the tensile loading thereof are described in detai with reference to Figs. 16 to 18 (not shown). Additional coupling between the two units may be effected by laterally-orientated crankedlinks (120), Fig. 19 (not shown). Alternatively, bollards 117, 118 may be lashed together. Motion of one unit relative to the other may be minimized by magnetic bonding. A retractable pin may be lodged in the recess in the motive unit so as to engage with the mating part of the other unit and thereby ensure positive coupling. When the units 30, 31 are united a wheelhouse 67 may be elevated on supports 68.

Title: Impact wrench torque control
IPC: B25B23/145
Filed: 1946-12-24
Abstract: 619,796. Screwing-up bolts &c. CHICAGO PNEUMATIC TOOL CO. Dec. 24, 1946, No. 37871. Convention date, Jan. 31. [Class 83 (iii)] An impact wrench comprises a tool head for driving bolts &c., an impact clutch embodying an anvil and a power-driven rotating hammer, and automatic means for disconnecting the power upon the attainment of a predetermined force of impact delivered to the tool head. An impact clutch, which is similar to that described in Specification 540,239 and has hammer dogs 53, is rotated by an air motor 22, controlled by a trigger 62 actuating a valve 59, and drives a tool head 37. The latter has a relatively-high torsional elasticity so that, following a blow, the rear of the head and hence the motor-shaft 32 rebound. In the rear of the shaft 32 is a stub-shaft 74 connected thereto by an overrunning clutch 75 and carrying an arm 79 which is thus rotated, against the constraining force of a spring 83, by an amount proportional to the force of impact. Air passes to the motor via a valve 64, having passages 63 in a head 65, and ports 71. On pressing the trigger 62, the valve moves back until arrested by a bellcrank lever 84 engaging a shoulder 91 on the valve-stem. When a certain rebound of the arm 79, predetermined by a stop-screw 81, occurs, the bell-crank is turned and the valve 64 released before the tool can be re-started. The air-supply to the motor is adjusted by a screw 88 which controls the initial opening of the ports 71. The arm 79 may be exposed to actuate a visual indicator.

Title: Improvements relating to associative digital data storage systems
IPC: G06F3/08
Filed: 1965-09-10
Abstract: 1,074,408. Associative stores. INTERNATIONAL BUSINESS MACHINES CORPORATION. Sept. 10, 1965 [Sept. 12, 1964], No. 38666/65. Heading G4C. In an associative data store, stored characters each include a mark indicating if the character is an address (tag) character. Referring to Fig. 2 (not shown), variablelength multi-character records can be entered into an associative recirculating store (SDLK) via a 16-character recirculating buffer store (ADLK) from a card reader (SCR), serially by bit. The characters from the reader are initially address characters, and blank characters to be later filled with data. All these characters have a ONE bit in a marker position. During a first phase, one character is placed in the buffer store per cycle thereof, detection of the marker bits preventing overwriting. During a second phase, characters are transferred from the buffer to the associative store, the marker bits ONE being removed from each blank character and the characters actually placed in the associative store being compared with those sent from the buffer store to prevent further transfers if unequal. Timing is controlled by a clock pulse generator (TG) driving a bit ring (BR) driving a 16-position character ring (CHR), the latter being stopped during phase two. Subsequently data characters can be entered into the blank positions by supplying a record via the buffer store and comparing its address character (staticized) with those in the associative store, and on equality gating in the data characters. The recirculating stores may each include a magnetostrictive delay line, or magnetic drum, disc or tape loop.

Filed: 1960-11-14
Abstract: 983,487. Synchronizing and checking arrangements for data-storage apparatus. GENERAL ELECTRIC CO. Ltd. Sept. 29, 1961 [Nov. 14, 1960], No.39057/60. Drawings to Specification. Heading G4C. Data words are recorded each as one bit on each of a number of parallel tracks (e.g. on magnetic tape) the bits being arranged on two lines across the tape, and read out into a register as two alternate groups of bits, the read-out from the register of each group being controlled by a signal derived from the reading from tape of the following (complementary) group. As described a 'word' consists of eight bits B 1 , B 2 , C 1 , C 2 , D 1 , D 2 , E 1 , F 1  arranged in two groups as follows: - the remaining eight bits being parity bits, A 1  completing even parity with B 1 , C 1 , D 1  and E 1 ; A 2  with B 2 , C 2 , D 2  and F 1 , and B 3 , C 3 , D 3 , E 2 , F 2  and A 3  completing odd parity for the sub-groups shown in the table above. Each word is read by 16 heads in the two groups, but distortion of tape or other irregularities may make the reading of bits of a subgroup, or sub-groups of a group, non-instantaneous. The Specification illustrates logic circuits for generation of the parity bits, and, for reading, 16 sets of 3 flip-flops, bits being read into the first of each set, read out to the second by a pulse derived from passing all the signals of one or two subgroups to an 'or' gate (each sub-group must contain at least one "1") and read out to the third by a pulse derived from passing all the sub-group pulses of a group to an 'and' gate. In this way the time-irregularities in the arrival of the bits is taken up, and the set of third flip-flops will, at the appropriate times, contain the 16 bits appropriate to single words. Logic circuits for correcting single errors in the bit representation as read, using the 8 parity bits, are described. Specification 641,680 is referred to.
