Title: Energy Dissipating Device
IPC: B60R22/28
Filed: 1968-06-13
Abstract: 1,170,404. Energy - absorbing devices. FORD MOTOR CO. Ltd. 13 June, 1968 [14 June, 1967], No. 28085/68. Heading F2E. An energy-absorbing device comprises an elongate sinuous member formed from non- elastomeric material, and an elongate retainer member secured to the sinuous member along the length of the latter by a plurality of fasteners. As shown, a metal strap 12, e.g. of coldrolled steel, is arranged in a series of waves 14 to the apices of which two restraining elements 26, 28 (somewhat narrower than the strap) are secured by hollow rivets 30, 31 &c. The end 18 of the strap may be secured to the floor of a motor vehicle passenger compartment while the other end 20 may be secured to the lap belt of the vehicle passenger restraining system. When axial tensile forces 32, 34 are applied, as during a crash, a progressive shearing of the rivets and straightening out of the waves 14 occurs. Preferably the device is made with sufficient waves and rivets to ensure that the passenger has come to rest before the force generated exceeds that which may be safely tolerated by the human body; such excessive force may occur after shearing of all the rivets and extension of strap 12 into a straight line.

Title: Improvements in or relating to production of radioactive isotopes
Inventor: CHARLTON JOHN CECIL
IPC: C01B32/50
Filed: 1954-09-30
Abstract: C14 is recovered from a neutron-irradiated metal nitride by heating the material in a stream of oxygen and passing the gases through an adsorbent for carbon dioxide.  Aluminium nitride in an aluminium can is irradiated with 1020 neutrons per square centimetre and then heated slowly to 600 DEG  C. in a slow stream of oxygen free from CO2.  The gases leaving this furnace are passed through a second furnace at 800 DEG  C. containing copper oxide to convert any CO to CO2 and then through two NaOH bubblers.  Air which is free from CO2 enters the bubbler train through a non-return valve when combustion commences (4AIN + 302=2AI2O3 + 2N2).  The aluminium nitride is preferably produced as described in Specification 784,126.  The Specification also refers to the recovery of C14 from neutron-irradiated nitrates and nitrides by acidifying an aqueous solution of the material to release CO and CO2.

Title: Improvements in and relating to control systems for electric motors
Inventor: BINNEY ERIC ALTON
IPC: H02P1/16
Filed: 1951-11-30
Abstract: 711,509. Control of D.C. motors. ENGLISH ELECTRIC CO., Ltd. Nov. 7, 1952 [Nov. 30, 1951], No. 28169/51. Class 38(3) A series motor 1 is accelerated by successively short-circuiting sections of a starting resistance 2, and a voltage which is automatically varied in accordance with variations of the armature current of the motor is injected into the motor circuit in series relationship therewith and in a sense to reduce such variations as sections of the starting resistance are cut out of circuit. An amplifying exciter 3 having a reference field winding 3a and an opposing control field winding 3b is connected across resistance-section 2d, the winding 3b being excited in accordance with the armature current of the motor. The motor is started with the full resistance 2 in circuit and the voltage of the exciter is initially equal and opposite to the voltage-drop due to the' main current across the resistancesection 2d. As the main current decreases the exciter provides a boosting voltage opposing the back electromotive force of the motor, and, when this boosting voltage reaches a predetermined maximum value, the combined fields due to coils 4c and 4a of a relay 4 become sufficient to close contacts 4b. Thus relays 12 and 6 are energized and section 2a of the starting resistance is removed. The resulting increase in armature current causes the field 3b to overcome the field 3a so that the exciter 3 now supplies a bucking voltage assisting the back electromotive force of the motor. The current through the relay coil 4c also reverses and the contacts 4b are opened to interrupt the circuit of the relay 12. As the motor accelerates the bucking voltage of the exciter 3 decreases to zero and then increases in the opposite direction, the relay 4 again operating when the boosting voltage of the exciter reaches its maximum value. Relays 13 and 7 are thereby energized to remove section 2b of the starting resistance. The further sequence of operations is similar to that described, the relays 12, 13, being energized alternately to remove consecutive sections 2c, 2d, of the starting resistance as the motor accelerates. When the motor reaches its full speed the exciter and its field windings are disconnected from their associated circuits. Further stages of control may be provided by resistances connected across the series field winding of the motor. The section 2d may be short-circuited in steps. The polarized relay winding 4a may be replaced by a permanent magnet or a suitable spring.

Title: Preparation of foamed polycaprolactams
IPC: C08G69/20
Filed: 1963-07-22
Abstract: Foamed polycaprolactams are prepared by heating e -caprolactam with an allylic azide blowing agent, in presence of a base catalyst, with a co-catalyst mixture of (1) 1,1,3,3-tetramethylcyclobutanedione and/or 2,2,4 - trimethyl - 3 - hydroxypentenoic acid b  - lactone; and (2) a suitable fast co-catalyst giving a no-flow time below 1.5 minutes.  Allylic azide blowing agents are compounds having an azido-methyl group attached and an unsaturated carbon atom C8-C24 aliphatic azides and benzyl azides or alkyl-substituted benzyl azides of 8-18 carbon atoms are preferred, the azides being used in proportions of 0.1-2% of the weight of total polycaprolactam. Base catalysts are lactam-base salts, formed by reacting lactam, suitably e -caprolactam, with bases strong enough to convert the lactams to iminium salts, preferably at a level of 0.5 moles per cent to 5 moles per cent of total lactam; sodium hydride is the preferred base. The co-catalyst (1) is employed as one or a mixture of the two compounds named above in proportion of 0.2 moles per cent-0.5 moles of the total caprolactam.  Suitable fast co-catalysts (2) are compounds which, at a level of 0.3 moles per cent of a composition of e -caprolactam with lactam-base catalyst, catalyse its polymerization in under 1.5 minutes at 150 DEG  C. to a point where the mixture will not flow.  Numerous such catalysts are specified and are used at 0.05-0.2 moles per cent of total caprolactam.  The polymerization is conducted according to the invention by heating the mixed components at above 130 DEG  C. Conventional fillers and additives may be used. Examples are given for the process, also a technique for testing suitable fast co-catalysts.  The process yields foamed polycaprolactam of good fine pore structure, and improved mechanical properties.

Abstract: 723,954. Cocking mechanisms for automatic guns. DUNLOP RUBBER CO., Ltd., TREVASKIS, H. W., and DEWAR, D. Oct. 22, 1953 [Nov. 19, 1952], No. 29184/52. Class 92(2). A fluid pressure jack mechanism for initially cocking an automatic gun comprises a cylinder 1 connected through an aperture 3 in the cylinder head 2 to a source of fluid pressure, an annular piston 5 slidable in the cylinder and having a tubular tail-piece 6 in which slides a second annular piston 15 with a piston rod 13 adapted to contact a part of the bolt of the gun ; a skirt 18 extending from the front face of the piston 15 has a guiding surface 19 and an annular recess 20 and spring latches 22 with heads 23 are secured in the cylinder head 2, the arrangement being such that on the piston 15 moving toward the head 2, the latches 22 are first deflected by the surface 19, the latch heads 23 then moving into the recess 20 to hold the piston 15 in the fully contracted position. This arrangement prevents the piston rod 13 " wandering " outwardly due to vibration to be struck by the reciprocating bolts. In operation, a valve is opened to admit pressure fluid into the cylinder 1 and both pistons 5, 15 are moved back, the latches 22 being deflected to allow the latch heads 23 to move out of the recess 20. Air behind the pistons escapes through apertures 8 and ports 12. The piston 5 slides in the cylinder 1 until it abuts a flange 4 and the piston 15 slides in the tail 6 of the piston 5 until it abuts a sleeve 10. As the piston rod 13 moves outwardly a spring-loaded spigot 27 therein contacts the bolt and is forced back against a spring 28 until a flange 14 at the end of the piston rod 13 contacts the bolt and moves it rearwardly until the gun is cocked. The valve is then operated to allow the pressure fluid to flow back to the reservoir, the jack however remaining in the extended position. On firing the bolt moves forward and carries the piston rod 13 with it until at the forward position of the bolt, the spring-loaded spigot 27 reacting against the bolt forces both pistons in to their fully contracted positions where they are held by the latches 22.
