Title: Collision detecting system for a motor vehicle
IPC: B60R21/01
Filed: 1972-05-25
Abstract: 1388636 Crash restraint devices NISSAN MOTOR CO Ltd 25 May 1972 [28 May 1971 14 Aug 1971] 24601/72 Heading B7B A collision detector system for use with a crash restraint bag or other occupant restraint carried on a vehicle includes a detector 10 for producing a collision signal when an object either approaches close to or contacts the motor vehicle, a deceleration detector 17 for producing a real deceleration signal having a magnitude proportional to the magnitude of the vehicle deceleration, a function generator for producing a reference deceleration signal upon receiving the collision signal, a comparator 14 for producing a drive signal when the real deceleration exceeds the reference signal for actuating the crash restraint bag &c. By means of the system inadvertent operation caused by soft contact during parking or garaging is avoided. The collision detector may be a normally open switch (50), Fig. 4 (not shown), closed by mechanical pressure or radar which detects the object. In another embodiment first and second detectors 10a, 10b, Fig. 11, are provided on front and side portions respectively of a vehicle travelling in direction J. A test signal generator 32, Fig. 1, produces a pseudo deceleration signal, a test trigger signal and a disabling signal. An alarm circuit operates if the generator 12 and comparator 14 circuits are inoperative.

Title: Improvements in or relating to processes for preparing pure alkali metal salts of penicillin and the improved product resulting therefrom
IPC: C07D499/16
Filed: 1946-08-19
Abstract: Pure alkali metal salts of penicillin are prepared from pure ammonium penicillin by distilling with water and an alkali metal carbonate or bicarbonate, maintaining the pH of the solution below 9 during the removal of the ammonia.  The proportions used are approximately stoichiometric and the distillation is preferably carried out under reduced pressure.  If the initial solution has a pH greater than 9, it is brought below this figure (preferably to within the range 6.7 to 8.5) by passing in carbon dioxide during the volatilization of the ammonia.  After the removal of the ammonia, the solution may be concentrated by evaporation under reduced pressure, and the alkali metal salt may be obtained in the solid state by crystallisation or freeze-drying.  Examples show the preparation of the salts of sodium potassium and lithium.  The Specification as open to inspection under Sect. 91 also describes the use of other alkali metal compounds (e.g. oxide, hydroxide) of such a type that no extraneous contaminants are left in solution after the removal of the ammonia.  When using strongly basic compounds of this type, control of the pH of the solution is effected by adding the alkali in portions or in a continuous stream during distillation, at a rate approximately equivalent to the rate of removal of ammonia.  This subject-matter does not appear in the Specification as accepted.

Bales of fibres are disintegrated in a machine that includes rotary shredder elements and a grate formed of bars that at one end are higher than the support for the bale so that the full weight of the bale does not bear upon the shredder elements. Where one shredder element 4 is employed, the bars 9 may be pivoted at one end on a shaft 10 and adjusted for position by a screw 13. In a machine employing two shredder elements 21, Fig. 3, two sets of grate bars 29, 30 are connected to a shaft 31 with an angle of approximately 170 degrees between them. Also connected to the shaft 31 is a lever 32 pivoted to a piston rod associated with a fluid pressure cyclinder 35. In this arrangement, the bars 29, 30 alternately have their ends raised according to the position of the piston in the cylinder 35 which is controlled by values 37, 38 operated by the rollers 18 of a bale reciprocating carriage 19. Specification 944, 078 is referred to.

Filed: 1972-05-26
Abstract: 1361340 Iron and steel production FRIED KRUPP GmbH 26 May 1972 [29 May 1971] 24993/72 Heading C7D [Also in Division F4] Iron ore pellets are fed into two heated shaft furnaces 3, reduced by a cracking gas and passed through shaft 5 with the cracking gas into an electric furnace 6. Cracking gas, supplied through a pipe 16, is passed into the shaft furnace containing the more reduced ore and then passed into the shaft furnace containing the less reduced ore after being washed in washer 19 and heated in exchanger 20. When one of the furnaces is emptied through shafts 5 and fed with new ore, the cracking gas is fed from the other furnace which now contains a partially reduced ore. The electric furnace 6 includes a slag tapping device 12 and is joined to an alloying hearth 10 connected to a vacuum plant 9. The furnace units (3') Fig. 2 (not shown) may be superimposed on one another, separated by funnels (24). The switching of the supply of cracking gas depending upon which furnace has the least reduced ore is not carried out here since the gas after washing and heating is passed into another furnace unit which has an ore which is less reduced but in which the degree of ore reduction remains constant as the ore passes through it. The cracking furnaces are heated by a hot gas such as Helium which is passed from a heater such as a nuclear reactor. The hot gas in both modifications is passed through pipes 14 to heat the shaft furnaces 3 and removed through pipes 15. Calcium carbide may be supplied to the electric furnace as a slag former.

Abstract: 803,335. Sharpening saws. DARRAS, O. J. Aug. 16, 1956 [April 13, 1956], No. 25071/56. Class 60. A machine for continuously sharpening a band or circular saw 16 comprises a swivelling support 1, a driven shaft 2 disposed inside the support for driving at its outer end a grinding wheel 4, a transverse tubular extension 5 in the support arranged eccentrically with reference to the shaft 2 and revolubly mounted in a stationary bearing 6, and a spindle 9 which is mounted coaxially in the extension and carries two cans 12, 13 acting through levers 14, 15 and return springs to effect, respectively, indexing of the saw and oscillation of the support to move the grinding wheel to and from the saw. The shaft 2 is driven at one end by an electric motor 3 and rotates the grinding wheel through a belt-and-pulley drive 18, 19. The spindle 9 is driven from the shaft 2 through worm gearing 10, 11 so that the cams 12, 13 produce synchronized movements of the support and saw, the lever 14 being arranged to intermittently advance the saw through a pawl 17 and the lever 15 to oscillate the grinding wheel to and from the saw. The grinding wheel is mounted on a carrier 21 rigidly fixed to a shaft 22 which is pivotally mounted in an extension bearing 23 on the support 1. If desired, the grinding wheel may be caused to oscillate about the axis of the shaft 22 by a cam 27 driven through gearing from the spindle 9 and actuating a pivoted frame 28 which is connected to the carrier 21 by a rod 31. The rod 31 consists of two telescopic parts 33, 34 which, when it is desired that the synchronized movements of the support and saw should be accompanied by a rocking motion of the grinding wheel, are locked together by a screw 35; this rocking motion may be prevented by releasing the screw and tightening a locking screw 36 on to the shaft 22. Alternatively, the grinding wheel may be mounted directly on the end of the driving shaft 2, the carrier 21 and associated parts being dispensed with.
