Patent GB-701708-A (GB)
Title: Improvements relating to the manufacture of tetraethyllead
IPC: C07F7/24
Filed: 1951-06-06
Abstract: Tetraethyl-lead is prepared by reacting an alloy of lead with ethyl chloride at an elevated temperature characterized by introducing a molten sodium-lead alloy into a reaction zone containing liquid ethyl chloride.  The alloy may be continuously sprayed or extruded in particle form into the ethyl chloride, and the reaction zone is maintained at reaction temperature or is maintained at a temperature below reaction temperature, the mixture then being heated to reaction temperature.  The preferred particle size is below 4 mesh per linear inch, e.g., between 8 and 300 mesh per linear inch.  The reaction temperature may be maintained between 40 DEG  C. and 100 DEG  C., the pressure being maintained at a value sufficient to keep the ethyl chloride in the liquid phase at the reaction temperature.  An excess of ethyl chloride is preferably employed in the reaction.  The ratio of ethyl chloride to lead may be between 0.5 to 1 and 6.25 to 1 by weight.  The residence time of the lead in the reaction zone may vary from 3 to 30 minutes.  Suitable lead alloys referred to are of the formulae NaPb, Na2Pb and Na3Pb4.  Two examples are given. Specification 685,230 is referred to.

Abstract: 1,042,823. Pulse radar. CANADIAN PATENTS & DEVELOPMENT Ltd. April 5, 1963 [Oct. 1, 1962], No. 13562/63. Heading H4D. In a radar system utilizing displaced beams P1, P2, Fig. 1, and incorporating a computer which calculates the co-ordinates of the origin of a projectile following a trajectory T (first target point), those co-ordinates are stored and compared with a subsequent computation of the co-ordinates of a second target point, and the differences therebetween are displayed. In the embodiment the second target point is that at which a " friendly " projectile lands; the apparatus described in Specification 1,042,822 is included, the enemy weapon co-ordinates being displayed on counters, both in polar co-ordinates originating at the radar and in map eastings and northings on counters CT10, CT12, Fig. 14. After computation of the enemy weapon co-ordinates, the co-ordinate difference counters CT13, CT14 are set to zero by operation of knobs CK1, CK2. Switch CFS is then closed thereby causing the computation of the second target point to effect the " difference " eastings and northings to be displayed by counters CT13, CT14; if the limits of counter CT13 are exceeded, cam CAM4 actuates switch S4 to de-energize clutch CL7 and thereby energize a lamp FL1 to indicate false reading; and similarly for counter CT14.

Abstract: 963,920. Igniting explosives. MINISTER OF AVIATION. May 15, 1963 [April 10, 1962], No. 13735/62. Heading F3A. [Also in Division F2] A shock-absorber for cushioning the landing shock on a parachute-borne load 10 comprises, under a load bearing platform 11, a layer 12 of side-by-side honeycomb cells 13 of a rigid crushable material having their upper ends 15 closed and lower ends 16 open towards the ground so as to be resistant to internal fluid pressure, some or all of the cells containing a charge of explosive 21 with means to detonate it predeterminedly so that the explosion acts to reduce the velocity of contact of the platform with the ground. Below the cells 13 is a chamber 17 with flexible sides 18 which inflates with air through ports 20 as the load falls. The explosive charges 21 are at the closed end of the cells. They are small charges of a substance, as for example nitroglycerine, which can be detonated spontaneously by a pressure wave. Alternatively mechanical means responsive to pressure may be used to initiate them. When the baseboard 19 hits the ground air in the chamber 17 is compressed and sends shock waves up the cells with the speed of sound which initiate the detonations. The cells may be made of resin impregnated paper or of metal foil.

Title: Control circuit for a telecommunication connection
IPC: H04Q3/54
Filed: 1973-03-22
Abstract: 1412354 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 22 March 1973 [30 March 1972] 13800/73 Heading H4K In a multistage switching network utilizing reed relays each of which has one of its own contacts in series with its coil and a marking diode connected to the junction of the coil and contact, a switching relay having contacts in the hold and speech paths is provided in a junctor at one end of a connection and a control circuit is also provided for releasing this relay at the end of a call prior to actual release of the crosspoint relays thereby ensuring currentless opening of the crosspoint contacts. Operation.-After path selection by a not shown computer, marker contacts mj1 (mj2) md and mc are closed and transistor TJ1 is pulsed on thereby bringing up switching relay Hr. The latter prepares a holding ground via its contact hr2 and cuts through the speech path at its contact hr1 (both speech wires are in fact cut through). Almost immediately transistor TD is also pulsed so as to operate crosspoint relay Dr and thus extend the constant current source T and positive battery marking Ba via dr1 to crosspoint relay Cr which comes up when TC is subsequently pulsed. Line (reed) relay Cor follows so as to close its heavy duty contact col and thus extend the hold path to negative battery y and to finally cut through the speech path via the intermediary of relay Ar. The marker withdraws. Release.-The marker closes its contacts (mj1) and mj2 and pulses transistor TJ<1>1. Relay Hr is thereby short-circuited but the hold path is maintained to positive battery Ba. When the discharge current via diode Dhl and hr2 falls sufficiently, relay Hr drops so as to open the hold and speech paths. When TJ<1>1 ceases to conduct, any energy stored in the distributed or lumped inductances of the hold path discharges via diode Dh5 whereafter Dr, Cr and Cor drop under virtually currentless conditions. Alternative switching relay circuit, Fig. 2.- Relay Hr1 in this case is not directly in series with the hold path but operates in response to conduction of transistor TH when the marker contact mj1 closes and transistor TJ1 is pulsed as previously discussed. At the end of the call, when mj2 is closed and TJ<1>1 is pulsed, the positive battery Ba is effective via diode Dh4 to temporarily hold the connection but since Hr<1> and TN are short circuited these release after the discharge of any stored energy via diodes Dh3 and Dh2. The latter diode also serves to protect TH against positive battery transients from Ba. Diode Dh<1>5 serves the same purpose as Dh5 in controlling the final release of the crosspoint relays.

Patent GB-1119715-A (GB)
Title: Polyesteramides
Inventor: GOODMAN ISAAC
IPC: C08G69/44
Filed: 1966-03-29
Abstract: Polyesteramides are polyamides of (i) at least one disecondary diamine in which at least one of the amino N atoms forms part of a heterocyclic group and in which the amino groups are separated by at least two carbon atoms, with (ii) at least one dicarboxylic acid: HOOC(CH2)nCOOH in which n is an integer from 2 to 10; the polyamide has incorporated in the macromolecular chain at least 5 but no more than 95 6-oxycaproyl units (-O(CH2)5 CO)- per 100 diamide plus 6-oxycaproyl units.  The 6-oxycaproyl and diamide units form at least 90 out of every 100 units in the macromolecular chains; the polyesteramides have a reduced viscosity of at least 0.3 dl. per g. measured in n-cresol at 25 DEG  C.  The diamine may be piperazine or 4,41-bipiperidyl and the dicarboxylic acid may be adipic acid or sebacic acid.  In a preferred polyesteramide the polyamide is formed from piperazine and adipic acid and the 6-oxycaproyl units form 60-85 mole per cent of the polymer.  The polyesteramide may be prepared by reacting an ester generating compound (e.g. e -caprolactone) with: (i) at least one diamine and at least one dicarboxylic acid as defined above, or (ii) an alkane dicarboxylate salt obtained from the diamine and dicarboxylic acid as defined above, or (iii) at least one polyamide derived from the said diamines and dicarboxylic acids. Reaction is carried out (e.g. at 180-300 DEG  C. in an inert atmosphere) until the polymer has a reduced viscosity of 0.3 dl. per g. at 25 DEG  C. in m-cresol. Reaction may be in two stages: (i) the reactants are heated in a nitrogen atmosphere to obtain a uniform melt, and (ii) the melt obtained is reacted in a rapid flow of nitrogen until a product of the desired intrinsic viscosity is obtained. The polymers may be used in fabricating fibres and films and may also be useful as adhesives.
