Title: A device for the operation of a magnetic powder clutch for electric driving motors
IPC: F16D37/02
Filed: 1952-03-17
Abstract: 703,039. Control of A.C. motors. ELEKTROMECHANIK GES. March 17, 1952 [March 16, 1951], No. 6899/52. Class 38(3) [Also in Group XXIV] When an electric motor starter is placed in the " running position the exciting coil of a magnetic powder clutch is energized. As shown applied to a three-phase induction motor the energizing coil 13 of a magnetic powder clutch is supplied, through a dry-plate rectifier 12, from a step-down transformer 11. When the motor is started its windings UX, VY, WZ are star connected as shown in Fig. 1, the primary of the transformer 11 is short circuited and the clutch will not be energized. The motor is thus allowed to attain full speed unloaded whereupon the windings are delta connected as shown in Fig. 2. Line voltage is then applied to the transformer 11 and the clutch engages. Reference has been directed by the Comptroller to Specification 649,553, [Group XXIV].

Title: A process for converting naphthalic acid into naphthalene-2.6-dicarboxylic acid
IPC: C07C51/41
Filed: 1953-03-10
Abstract: In a process for the conversion of naphthalic acid into naphthalene-2,6-dicarboxylic acid or a derivative thereof the dipotassium salt of naphthalic acid is heated to temperatures above 340 DEG  C., thereby obtaining the dipotassium salt of naphthalene-2,6-dicarboxylic acid.  Elevated or normal pressures may be employed and carbon dioxide may be present.  Metals such as zinc, cadmium and lead and their compounds, e.g. the oxides, are mentioned as catalysts which may be employed and the catalysts may be applied to carrier materials.  The potassium salt of naphthalic acid may be mixed with sand, coke, inert salts, e.g. potassium carbonate, sulphate and chloride or pieces of inert metal to facilitate thermal conduction within the heated salt.  Reaction mixtures which produce the dipotassium salt of naphthalic acid on heating may be used as starting materials, e.g. mixtures of naphthalic acid, anhydride and potassium carbonate.  Free naphthalene-2,6-dicarboxylic acid can be obtained by acidifying an aqueous solution of the salt or the latter may be converted directly, e.g. to the dichloride or esters.  In exaples: naphthalene-2,6-dicarboxylic acid is obtained by heating anhydrous potassium carbonate and naphthalic anhydride under carbon dioxide at elevated pressure, dissolving the product in water and acidifying with hydrochloric acid (1) and in similar processes cadmium oxide, zinc oxide, litharge and metallic lead are employed as catalysts (2).  The conversion of naphthalene-2,6-dicarboxylic acid to the dichloride, the dimethyl ester and the diamide is mentioned.

Title: Data processing apparatus
IPC: G06F11/22
Filed: 1976-02-23
Abstract: 1485257 Diagnostic testing INTERNATIONAL BUSINESS MACHINES CORP 23 Feb 1976 [14 April 1975] 06972/76 Heading G4A A data processing system comprising a CPU, a storage unit and a channel unit which is connected to a plurality of I/O adapters includes, as one of the I/O adapters, a unit which is arranged to selectively address any other functional unit in the system and to supply it with diagnostic test signals. The testing unit (system control adapter) includes a read-only control store containing "hardcore" instructions for loading a random access control store with a program from from a magnetic disc unit or load/dump unit. Both control stores have a common address register which is initialized at a preset address. The system control adapter executes the stored program to effect selective testing of the other units in the system. The program loads selected address, control and test pattern information into registers 120, 170, 175, 180, 185. Address information in register 175 is decoded to select particular functional units over respective lines 117 by enabling a set of input gates 251, 252, 255, 256 and 261, 262. An addressed unit to be tested is also supplied with a test control signal on a line 116 to disconnect it at gates 265, 275 from the channel and device interfaces thus isolating the unit from the remainder of the system. The system control adapter supplies clock signals C1, C2 in common to all the units in the system from a clock control 103 (details, Fig. 9, not shown) which, under program control, can interrupt the supply of clocks C1, C2 to the addressed unit, and after the stoppage can selectively supply C1 or C2 as a clock step, one cycle of C1 and C2 as a machine cycle, or one, two, or three cycles of C1 and C2 as an instruction cycle, the latter being determined by a programloaded counter. Derived clocks A, B can also be supplied in either relative phase to shift serial data into or out of latches L1, L2 in the addressed unit, the latches being controlled to operate as a shift register when in diagnostic test mode. Thus a predetermined data pattern may be supplied from register 170 over line 118 to latches L1, L2 of the addressed unit which may then be stepped through an operation and the contents of the latches returned over a line 119 for comparison with an expected pattern by EXOR circuit 400. I/O devices which may be included in the system, apart from the magnetic disc unit, are magnetic tape, CRT, keyboard, and printer.

Abstract: 1,171,191. Closing wrap - around cartons. MEAD CORP. 16 Feb., 1967 [16 Feb., 1966], No. 7424/67. Heading B8C. Plungers, mounted on each side of a moving wrap-around container, reciprocate to close a pair of end flaps attached to opposite side walls of the container. In the form shown in Fig. 4, telescopic plungers 86, 87 and 89 are carried on belts 81, 81A respectively, travelling at the same speed as the containers 38. When plunger 89 reaches a position 98 on a fixed guide rail it begins to extend towards the carton to fold the leading and trailing end flaps 70, 68 respectively of adjacent containers. Similarly the plungers 86, 87 then move to fold the remaining flaps 71, 69. As plungers 86, 87 approach the limit of their extension they partially rotate so that eccentric fingers 116 mounted on their tips push the end flaps inwards to effect the engagement of a tongue on one flap with a slot in the other (as at station B9). The rotation is effected by a helical groove in the plunger mounting. The completed container, Fig. 3, includes a partition 64 separating two rows of bottles housed therein. The blank, Fig. 2 (not shown), to form the container, was withdrawn from a magazine (7) Fig. 1 (not shown) by suction grippers (14) and laid atop a group of bottles. Initial folding of the blank is effected by ploughs (80), which fold the side walls.

Class 52(3) A page turner has an arm 8 carrying gripper 9 mounted on the oblique pivot 42 of the box 7 which contains a torsion spring and translates the motion of the core of the Bowden cable 10 into a rotational movement of the arm 8. The gripper 9 comprises a pin 21 carrying a reel of self adhesive tape which passes round roller 22 and is taken up on drum 23, the drum being fixed to the shaft 17 which is rotated so as to expose a fresh piece of tape after each turning of a page by a ratchet mechanism in the housing 20 being actuated by lever 18 and cord 26. The cycle of action when a page is turned is as follows: the arm 8 rotates with a page held by the gripper 9, the cord 26 engages a stop in the box 7 thus applying an increasing tension on the lever 18 which advances the tape and then causes the gripper to rotate about the pivot 13 finally freeing the page which by this time has moved past the spring loaded retaining finger 11 which has been temporarily released by the action of arm 8 on the end 28 of the finger. The Bowden cable is intended to be operated by a foot pedal. German Specification 800,273 is referred to.
