Title: Improvements in or relating to an Alarm Mechanism to Prevent the Unauthorized use of Motor Vehicles.
Inventor: WADE HAROLD
IPC: B60R25/10
Filed: 1917-07-30
Abstract: 116,593. Wade, H., (Beardmore, J. C.). July 30, 1917. Theft and like alarms.-When unauthorized use is made of a motor-vehicle, an alarm is sounded automatically when the steering apparatus is moved in either direction. The device can be locked out of use for normal running. A casing comprising two separable telescoping members 16, 17 is secured to the steering column by a clip 23. The members 16, 17 are provided with slits 20 in staggered relation, and have tongue and strap engagement at 22. They are also held by a hook 83 controlled by the locking means for setting the device. The member 17 supports two belle 38, 39 which are struck by corresponding hammers 53, 54 carried by the armature 47 of an electric bell mechanism. Batteries 28, 29 are secured within the casing by clips. The bell circuit is controlled by normally open contacts 86, 87. A plunger 57 urged towards the steering post 64 by a spring 58 ends in a pivoted finger 61 held in alinement by a spring plunger (not shown). The plunger 57 is normally held in the position shown with the finger 61 clear of the post 64 by a plate carried by the plunger and having an opening with a hook-shaped projection 74 engaged by a pin 75. The pin 75 is carried by a rotatable barrel forming part of any suitable key-operated lock. To set the device, the barrel is rotated in anti-clockwise direction to bring the pin 75 to the other side of the hook 74. The plunger is thus free to move under the action of the spring 58. The plunger moves until the finger 61 rests against the post 64. Any subsequent rotation of the post 64 deflects the finger 61 and allows further movement of the plunger, a projection 72 then closing the contacts 86, 87. Rotation of the lock barrel also serves to oscillate the pivoted hook 83, which, in the intermediate position, is disengaged from an eye 84 on the member 16, so that the parts 16, 17 may be separated for access to the casing. The hook is re-engaged when the barrel is completely rotated to the setting position.

Title: Improved phosgenation process for the manufacture of diphenylene-4:4-diisocyanate
Inventor: FRANCE HAROLD
Filed: 1955-04-20
Abstract: Diphenylene 4,41-di-isocyanate is produced by reacting benzidine hydrochloride with phosgene between 120 DEG  and 140 DEG  C. preferably in the presence of an inert organic liquid.  The liquid used should boil above 120 DEG  C. and preferably be a chlorinated hydrocarbon, e.g. o-dichlorobenzene.  A suitably pure grade of benzidine hydrochloride is obtained by steam distillation of commercial benzidine hydrochloride, treating with decolorizing charcoal and salting out.  It is important for the reactants to be dry.  A rapid stream of phosgene is passed through a vigorously stirred suspension of benzidine hydrochloride in, for example, o-dichlorobenzene, until the required temperature is reached.  Any diluent which distils is condensed and returned to the reaction mixture, whilst any hydrogen chloride formed, or unreacted phosgene, is allowed to escape.  Phosgenation is continued at this elevated temperature until only traces or no hydrogen chloride can be detected in the effluent gases.  Dissolved phosgene and traces of hydrogen chloride may be removed by a stream of dry nitrogen at a temperature up to 140 DEG  C. and the crude o-dichlorobenzene solution of the di-isocyanate filtered.  The solvent may be removed under reduced pressure at temperatures below 120 DEG  C. and the di-isocyanate further purified by distillation under still further reduced pressure, or by such processes as crystallization from a non-reactive solvent.  Examples are given illustrating the effects of various temperatures of phosgenation and various organic solvents.

Filed: 1966-03-16
Abstract: 1,076,911. Data transmission. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 16, 1966 [July 2, 1965], No. 11514/66. Heading H4P. In a system in which data is transmitted in blocks and errors are corrected by repetition, the format of the blocks is changed in accordance with the frequency of occurrence of errors. The embodiment described employs long and short length blocks as the two formats. Each transmitted block comprises data bits, an RQ bit indicating that a block previously received at the transmitter from the remote station was found to be correct or requires to be repeated, a mode bit which normally alternates in state from block to block, and check bits. Binary data is passed to a store and to a unit which assembles the data into blocks together with the check bits, the mode and RQ bits being added from a control unit fed by the local receiver. The length of the block, i.e. the format, is also controlled by this unit. A request for repetition results in data being read from the store, a short block format containing this data being transmitted. Under given circumstances one mode signal, or a sequence of mode signals, is inverted. The control unit checks that the mode bit received is that expected. At the receiver the data and check bits are separated from the remainder of the block, which passes to the control unit, and the data is passed to the output device if no error is found in the block and if the data has not already been received and passed to the output. Detection of any error causes transmission in short block mode. When m successive short blocks have been received without error the format is changed to long block mode.

In a speed-frame having flyers mounted to rotate in upper and lower bearings and driving shafts for flyers and bobbins having fixed axes, each bobbin receives its lifting and rotating movement by means of a vertically-movable and rotatable bobbin carrier which receives its rotation by being keyed to an axially-fixed rotatably-mounted sleeve rotated through a gear-train from a shaft with a fixed axis, while its vertical movement is received from a non- rotary lifting-sleeve held against rotation by being keyed in a fixed sleeve and moved vertically by a rack-and-sprocket from a shaft with a fixed axis. In Figs. 2, 3 the bobbin 30 is secured by a member 56 having a roughly triangular part engaging in an opening of corresponding shape on the top-member of the bobbin, to a carrier 50 constituted by the tubular upper part of a shaft 5. For its rotation, the shaft is keyed at 55 to a sleeve which is rotated by gears 35, 41, the latter being on a fixed driven shaft 40. For its vertical movement the shaft is mounted in a sleeve 60 so that it can rotate in it and move vertically with it; the sleeve moves on a guide 70 to which it is keyed at 62 to stop it rotating, and has a rack 61 engaging a sprocket 64 on a fixed driven shaft 63. The flyer is driven by being attached to a sleeve 14 driven by gears 18, 21, the sleeve 31 being rotatably mounted in the sleeve 14 by bearings 33, 34. In Figs. 10, 11, the bobbin is secured at 56 to be carried by a sleeve 59 which is carried by the upper part 67 of a shaft 65 so as to rotate around it but to move vertically with it. The sleeve 59 is mounted in sleeve 31 so as to rotate with it (key 59a) but to move vertically relatively to it. The sleeve 31 is rotated, and shaft 65 raised, as previously described.

In a viscometer in which a rotatable member 12 incorporating a permanent magnet 17 is driven in a flowing fluid 11 by a rotating magnetic field which acts on the permanent magnet the angular displacement of the member 12 with respect to the rotating field is measured. The rotating magnetic field may be provided, as shown, by a permanent magnet 18 rotated at a uniform speed, or by a rotating electromagnetic or electrically with an alternating current. In order to measure the lag of the member 12 with respect to the rotating field ferromagnetic members 20, 23 on the body 12 and magnet 18 co-operate with respective pick-ups 21, 22 to produce electrical signals. These signals act through a bi-stable circuit to connect one or other side of a voltage source to a resistor through which a capacitor is charged or discharged. The voltage across the capacitor is compared with that of a tap on a potentiometer connected across the voltage source to give an analogue read-out. Photo-electric sensing means may be used. If magnet 18 is an electromagnet the energization of the magnet may be adjusted in accordance with the output of a temperature sensor immersed in the fluid to compensate for changes in viscosity due to temperature variations.
