Title: Improvements in or relating to the production of aminonorbornane derivatives
IPC: C07D261/18
Filed: 1965-12-17
Abstract: Novel compounds of the formula <FORM:1090686/C2/1> (wherein R is hydrogen, alkoxycarbonyl, aryloxycarbonyl, alkaryloxycarbonyl or aralkoxycarbonyl and a condensed benzene ring with or without one or more substituents can be present between the 5- and 6-positions) are prepared by reductive dehalogenation or elimination of hydrogen halide with a base followed, if the removal of the hydrocarbyloxycarbonyl group is desired, by hydrolysis, from a compound of the formula <FORM:1090686/C2/2> (wherein X is a halogen), prepared as described in Specification 1,090,687.  The free amine products may subsequently be N-acylated. The reductive dehalogenation may be effected by catalytic hydrogenation or by the use of an alkali or alkaline earth metal in liquid ammonia (this latter method preserves a double bond in the starting material).

Title: Improvements in fuel injection pumps for internal combustion engines
IPC: F02M59/36
Filed: 1965-12-20
Abstract: 1,068,729. Fuel injection pumps. ROBERT BOSCH G.m.b.H. Dec. 20, 1965 [Dec. 24, 1964], No. 53852/65. Heading F1A. In a fuel injection pump the quantity of fuel delivered by cam actuated piston 1, through outlet valve 5 to an engine cylinder or through a distributor to several cylinders, is controlled by a regulating valve 15 which controls communication between spill passages 23 and 24. The valve 15 is actuated against the bias of spring 16 by fuel delivered from auxiliary piston 6 the effect of which is modified by a throttled connection 30a to a chamber 31, housing an accumulator piston 32, and a throttled return passage 25 to the auxiliary cylinder 7. The throttle 30a is controlled by the edge 38 of rotatable throttle member 36 and the initial position of the valve 15 is determined by an adjustable stop 18, 19, the stop and throttle being adjustable simultaneously by an adjustable linkage 40, 41, 42 between stops 43 and 44 which set the idling and maximum speeds respectively of the engine. At idling speed the movement of the valve 15 is controlled by the setting of throttle 30a and at maximum speed the throttle 30a is closed and the speed is determined by the throttle 26 restricting flow back to the auxiliary cylinder 7 from regulating valve chamber 14 and preventing the valve 15 engaging stop 18 between delivery strokes of the piston 1. The inlets 3 and 9 to the cylinders 2 and 7 are arranged such that the delivery of the auxiliary piston 6 begins before that of injection piston 1.

Title: Improvements in or relating to information storage arrangements
IPC: H04Q3/42
Filed: 1965-12-21
Abstract: 1,130,392. Automatic exchange systems. SIEMENS A.G. 21 Dec., 1965 [21 Dec., 1964], No. 54008/65. Heading H4K. Subscribers' meter total main storage compartments in a store SP contain a transfer bit and the address of an overflow storage compartment to which the excess total is transferred when the total exceeds the capacity of the subscriber's storage compartment. Should the capacity of the overflow storage compartment be exceeded a further overflow storage compartment is taken into use. Storage compartments, both main and overflow, are accessed by an address register ARV in order to obtain their content in a register EAR. A register ART contains an abbreviated address of the overflow storage compartment last seized for use. In conditions which do not involve overflow, a main storage compartment is accessed by an address TNX fed to register ARV and the existing meter total is set up in EAR. The meter charge Y to be added to this total is supplied over gate G3 to an adder AD to which the total is also supplied over a gate G4. The resulting new total is fed to EAR over gate G2 and from there it is written into the main storage compartment. Should the addition of the Y metering units produce a total in which binary one appears in the most significant bit position the register EAR signals an overflow situation and transfers the new total less the most significant bit to the register ART from which at the same time it extracts the abbreviated address of the last overflow storage compartment to be seized for use. This abbreviated address is circulated through the adder AD to be increased by one and returns to EAR to be written in the main storage compartment along with binary one in the most significant digit position. The address of the main storage compartment can now be cleared from ARV to be succeeded by the address of the overflow storage compartment. This address is obtained from the abbreviated address, preserved in EAR, increased by a fixed digit F1 in the adder AD. Given access to the overflow compartment EAR transfers the abbreviated address of the overflow compartment to ART and obtains from ART the new metering total less the most significant digit for registration in the overflow compartment. Subsequent applications for the addition of metering units to the subscriber's main storage compartment produce in register EAR the address of the overflow compartment which is then set up in the address register ARV, having been increased by the factor F1, in place of the address of the main compartment. Subsequent additions are therefore effected in the overflow compartment. Should the capacity of the overflow storage compartment itself be exceeded the register EAR signals a second overflow condition and seizes a second overflow storage compartment. The address of this second compartment is related to the address of the main compartment by a fixed numerical factor F2 and is obtained from it in the adder AD. The store SP can be comprised of magnetic film or magnetic cores.

Title: Electrical connector
IPC: H01R24/38
Filed: 1969-11-07
Abstract: 1294701 Two-part couplings G & H TECHNOLOGY Inc 7 Nov 1969 [8 Nov 1968] 54670/69 Heading H2E Two parts 12, 14 of a connector 10 are locked together so as to be quickly releasable by axial movement only of a keeper sleeve 116 on the part 14, the movement being produced by hand or by means of a lanyard or an actuator package. In order to engage the parts 12, 14, the keeper sleeve 116 is pulled rearwards, compressing a spring 122 and allowing resilient segmental fingers 90, which are attached to a pilot sleeve 124 on the part 14, to move radially outwards so that the forward tip of the keeper sleeve 116 becomes latched behind outwardly facing shoulders 130 on the fingers 90. The parts 12, 14 are then aligned with the aid of a polarizing key and keyway so that the pilot sleeve 124 enters a corresponding annular recess 126, and the fingers 90 are moved axially forwards by means of their collar 94 until their tips 110 pass over a peripheral shoulder 112 on a metal shell 16 of the part 12. The keeper sleeve 116 is then automatically released and is urged forward by the spring 122 to lock the finger tips 110 behind the shoulder 112. In the connected state, a fluid-tight seal is ensured by a silicone rubber gasket 68 which is kept under compression between connector faces 36, 36<SP>1</SP> by a spring 104. An indicator mark 142 on metallic shell 18 of the part 14 is hidden by a finger collet 96 when the parts are fully engaged. The connector parts are released by moving the keeper sleeve 116 rearwards, allowing the finger tips 110 to clear the shoulder 112. Further rearward movement of the sleeve 116 causes its rear face 132 to contact a stop 134 on the collar 94, and the consequent movement of the latter causes a finger flange 92 to abut a shoulder 102 on the shell 18 and to separate the shell 18 from the shell 16. The shell 16 contains an assembly 22 of electrical socket contacts 58 connected to wires 38<SP>1</SP> and mating with a corresponding assembly 24 of pin contacts 34 in the shell 18. Electrical continuity between the shells is ensured by a flexible metallic ring 74 which bridges the gasket 68 and bears on a silver ring 82 welded to the end of the shell 18.

Title: Measuring the acceleration of a motor or motor vehicle
IPC: G01P15/16
Filed: 1970-11-18
Abstract: 1319504 Measuring acceleration SNAM PROGETTI SpA 18 Nov 1970 [18 Nov 1969] 54908/70 Heading G1N Acceleration of an internal combustion engine is measured by measuring the time taken for the time interval between pulses derived from the ignition contact-breaker to drop from a value corresponding to a first given speed to a value corresponding to a second, higher, given speed. As shown, pulses from the contact-breaker trigger a monostable multi-vibrator 1, the output of which is differentiated at 13, the resulting positive and negative pulses 15, 16 being separated at 14. The pulses 16 are fed to a monostable multivibrator 2 the pulse duration of which corresponds to the second speed, and, via an OR gate 8, to a monostable multi-vibrator 3 the pulse duration of which corresponds to the first speed. When the engine reaches the first speed, AND gate 5 energizes a memory 9 which starts a chronometer 6; when the second speed is reached, AND gate 4 de-energizes the memory 9 and stops the chronometer 6. A signal sent via a second memory 7 to the OR gate 8 prevents further operation of the monostable multi-vibrator. The chronometer 6 and memory 7 are reset to zero by a pushbutton 12.

Abstract: 1362234 Modulating light HEWLETTPACKARD CO 26 Nov 1971 [14 Dec 1970] 55059/71 Heading H4F  When a narrow waveband portion of a plane polarized optical wave 14 passing through a birefringent medium 11 is selectively diffracted into the orthogonal polarization by a collinear acoustic wave 5, the frequencies of the diffracted optical and acoustic waves being related by a k-vector matching condition, and when the acoustic frequency is varied to alter the frequency of the diffracted optical wave, there results an instantaneous distribution of acoustic k-vectors along the collinear path whereby coherence between the optical and acoustic waves is reduced and the diffracted optical waveband is lowered in intensity and broadened in frequency, Fig. 3 (not shown). This may be compensated by varying the birefringence of medium 11 along the collinear path. In Fig. 1, a transverse electric field is imposed, its magnitude (and polarity) varying along the collinear path, and being produced, as shown, by a variable voltage source 25 and resistive electrodes 23, 24. Alternatively the variation in birefringence may be produced by a thermal gradient along the collinear path, Fig. 4 (not shown), or by a strain gradient (not shown). An analyser 17 is disposed either to transmit or to reject the diffracted optical wave.

Abstract: 1336604 Spray carburetters ROBERT BOSCH GmbH 27 Nov 1970 [1 Dec 1969] 56432/70 Heading F1B Fuel injection system for and I.C. engine having separate ignition and continuous injection into the inlet manifold comprises a gauging element and a throttle valve in series in the inlet manifold, the gauging element consisting of a disc fixed at one end of a balanced rocking lever arranged across the direction of air flow and which is displaced against a restoring force through a distance proportional to the amount of air flowing through the inlet manifold so that it moves into a section of the inlet pipe which is divergent in the direction of air flow, the movement of the lever controlling the crosssectional area of a fuel-valve passageway to meter an amount of fuel proportional to the airflow. Combustion air is drawn through a filter 2 in a housing 1 and acts on a gauging element 4, moving it into a conical section 3. The air flow is controlled by a butterfly valve 8. Gauging element 4 is fixed to a lever 9, supported on a pivot 10 and counter-balanced by a sliding weight 11 locked by a screw 12. The lever 9 carries a roller 40 which bears on the end of the movable part 15 of a fuel metering valve. Fuel is drawn from a tank 21 by a pump 19 and fed to an annular channel 25 in the meter housing, which communicates with a number of chambers 28 and with the reduced-diameter centre section of the movable part 15. As the part 15 is moved the centre section overlaps ports 31 by which the fuel passes to chambers 32 and hence through passages 33 to the injection nozzles. A diaphragm 29 forms one side of each of the chambers 28 and 32 and also acts as a flap valve for the passages 33, to maintain a constant pressure drop across the valve irrespective of the amount of fuel passing through it. The constant restoring force against which the movable part 15 is displaced is provided by feeding fuel under pressure from the line 22 to a chamber 37, where the fluid pressure acts on the end face 17 of the part 15. A throttle orifice 38 damps the movement of the part 15. The roller 40 acts at a position away from the centre-line of the movable part 15 so that it imparts a rotational movement which reduces friction. In a modification Fig.2 (not shown) the roller 40 is replaced by a lug having a curved surface which modifies the movement of the part 15 to compensate for errors in the fuel-air ratio arising from throttle effects in the induction pipe.
