Title: The Production of Acylated Urea Polyisocyanates
IPC: C08G18/78
Filed: 1966-05-24
Abstract: 1,152,915. Acylated urea polyisocyanates. FARBENFABRIKEN BAYER A.G. 24 May, 1966 [24 May, 1965], No. 23056/66. Heading C2C. Acylated urea polyisocyanates of the formula wherein z is 1 to 5, and R and R<SP>1</SP> each represent an aliphatic, hydroaromatic, araliphatic or aromatic radical, which may be substituted by chlorine or a nitro group or a group -S-CO-NH-R-N = C = O -O-CO-NH-R-N = C = O or -NH-CO-NH-R-N = C = O, O, and X represents hydrogen or CO-NH-R-N= C=O, R being derived from the organic diisocyanate and R<SP>1</SP> from the organic monocarboxylic acid, are obtained by reacting 4 mols. of an organic diisocyanate with one mol. of an organic monocarboxylic acid having more than one carbon atom at 90-190 C. in such a way that the diisocyanate is always present during the reaction in an excess such that at least 2 mols. of the diisocyanate remain in excess after completion of the reaction. The process may be effected in the presence of a catalyst, e.g. tertiary organic bases, metal salts, phosphines or ethyleneimine derivatives or by employing the monocarboxylic acid wholly or partially as a tertiary amine salt, and an organic solvent may be employed. The products may be modified, e.g. by effecting the reaction in the presence of small quantities of compounds having reactive hydrogen atoms. The organic monocarboxylic acid, which may be in gaseous, liquid or solid form or dissolved in a neutral solvent may suitably be added to the reaction mixture as a function of time equivalent to the evolution of CO 2 .

Filed: 1963-06-11
Abstract: 1,076,577. Variable capacitors. ULTRA ELECTRONICS Ltd. Sept. 11, 1964 [June 11, 1963], No. 23151/63. Heading H1M. [Also in Divisions G and G3] In a control system for a machine tool, the position of a member is determined by coarse and fine capacitive elements connected across an A.C. supply. A desired positioning sequence is carried out manually and each position is stored as the settings of fine and coarse potentiometers, connected to the capacitive elements in a bridge network or as balancing potential dividers to the rectified tapped potentials of the capacitive elements. During automatic operation the fine and coarse potentiometers are sequentially selected in an undisclosed manner and the member moved to the desired position by a closed loop servo system.

Title: Improvements in or relating to electrical signalling systems
IPC: H04M15/08
Filed: 1946-08-03
Abstract: 627,577. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BAKER, G. T. Aug. 3, 1946, No. 23188. [Class 40 (iv)] In a line identification system of the type described in Specification 614,177, the identification signals are sent in response to a signal from an operator whose position comprises equipment for displaying each digit immediately it is received. The description is identical with that of Specification 627,613, which claims other features. Reception of identity signals, Figs. 5 ... 8. Operation of key KI in the operator's cord circuit, closes a circuit for relay H which when the distributer relay set DRS is free, operates and connects up HR, battery being connected to the tip of the plug. Release of the key initiates transmission of the identity signals which are received over the +, - wires by a 2V.F. receiver in DRS which registers the digits on relay sets such as W ... Z, controlled over banks 2 ... 5 of a distributer switch DS, which is stepped after each digit over the lead PU. As described in Specification 624,089, the WXYZ contact trees connect appropriate voltages to the plates PX1, PY1 of the cathoderay tube CRT to cause its spot to trace the outline of the digit registered in the previous position of DS. Steady D.C. voltages applied over DS8 to plate PX2 cause the digits to appear in consecutive positions. When all the digits have been received H releases to free the common equipment DRS, but the digit switch continues stepping due to interaction with relay P, repeating the digits several times in succession to the cathode-ray tube whose after-glow gives the effect of a steady display. Transmission of identity signals. Figs. 3, 4 show a main exchange circuit capable of dealing with both incoming junction calls and local calls. Relays AS, ASS operate on insertion of the operator's plug and if the call is a local one ALD operates over the meter wire M. Relay ARR operates momentarily to, the operator's key KI and ADP, ASI pull up, the latter causing the transmission, by equipment SMLE, of the calling subscriber's identity via the M-wire and the transformers TRB. The operator may cause the identification to be repeated by re-operating and releasing ARR. On a junction call ALD does not operate so that ARR is followed by ADD which sends battery reversals to the calling exchange. The latter contains equipment similar to that part of the equipment just described which deals with local calls, but with ARR replaced by a polarized relay and the ALD contact replaced by a discriminating contact of the level to which the outgoing junction belongs. The equipment as shewn in Figs. 3, 4, but with ARR replaced by a polarized relay, can be used for a tandem exchange catering both for calls originated at the tandem exchange and for through calls.

When in position above one of the tables the plates are released from the cups U2. Each chain 2 has rollers r which are guided in channels 24 secured to framework 3. The suction cups Ul are releasable from a plate by means of rods 37 which, when moved toward the centre of the cup, cause the edge of the cup to be turned up and the suction seat to be broken. Actuation of the rods 37 is by arms 38, controlled, via linkage 39, 40, by a fluid pusher 41. The cups U2 are similarly controlled. The auxiliary chains 12, 12<1> are guided in channels 24<1> which are movable vertically by a ram 28. In a stacking operation, the conveyer C and the chains 2 are driven at substantially the same speed and a plate S suspended from the cups U1, is conveyed towards one of the tables P1 or P2. The auxiliary chains 12, 12<1> are accelerated to the same linear speed as the chains 2, the chains 12, 12<1>, by means of the guides 24<1>, are lowered and the cups U2 engage the plate S. The cups U1 are then released from the plate, the chains 12, 12<1> are stopped when the plate is above the required table P and the cups U2 are released. The tables are adjusted to keep the top plate at the same level. Tensioning of the chains 12, 12<1> is controlled by ram-actuated pivotal supports 20 for sprockets 21 of the chains 12, 12<1>. Alternatively, springs may replace rams 23. In Fig. 8 (not shown), guides (24<11>, 24<111>) for the chains 12, 12<1> are divided into sections, to aid the handling of longer than normal plates S. The plates may be deposited in a box, placed on the tables, for packing and shipping. The apparatus may be used for unstacking plates which, after being transferred from the auxiliary chains to the main chains, are discharged or piled in another way.
