Power is supplied to the solenoid through a circuit controlled by a switch which is, in turn, operated by the removal or replacement of a token from a storage position. As described the token is a permanent magnet and the switch a leaf-switch which closes when the magnet is put in position. Opening or closing the switch generates an electrical pulse in a pulse circuit. This pulse, via timers and relays, allows a current to pass for a short time, after a delay, to the solenoid and thus permit the door to be opened during this short time. Closing the door automatically engages the lock.
Patent GB-642752-A (GB)
Title: Improved method of producing pinacols
IPC: C07C29/38
Filed: 1947-10-24
Abstract: Pinacols are prepared by reducing a ketone, e.g p-hydroxypropiophenone with an alloy of lead and an alkali metal, e.g. sodium, potassium or lithium in a solvent capable of forming nascent hydrogen under the reaction conditions, such as alcohol, mixtures of glacial acetic acid and alcohol, aqueous alcohol or water.  In a preferred modification alkaline earth metal ions, i.e. ions of magnesium, calcium, barium and strontium, are added to the reaction mixture either by adding an ion producing salt or other compound to the reaction mixture, or by incorporating an alkaline earth metal in the alkali metal-lead alloy.  The alkali metal-lead alloy may contain from 5-40 per cent of alkali metal, preferably from 8-15 per cent.  Ketones which may be reduced include dialkyl, alkyl aryl, diaryl and alkyl aralkyl ketones and substitution derivatives thereof in which the substituent group is non-reactive under the conditions of the reaction. Water-insoluble ketones containing a group such as hydroxy, carboxyl or sulfo capable of forming a water-soluble salt may be converted to the salt and the reduction is then carried out in water.  In examples, there are obtained by reduction of the appropriate ketone with a sodium lead alloy, 3 : 4 - bis - (p - hydroxyphenyl) - 3 : 4 - hexanediol, 4 : 5 - bis - (p - methoxyphenyl) - 4 : 5 - octanediol, 3 : 4 - bis - (p - chlorophenyl) - 3 : 4 - hexanediol and 3 : 4-diphenyl-3 : 4-hexanediol, and by reduction of p-hydroxypropiophenone with a sodium lead alloy in alcoholic acetic acid followed by acetylation there is obtained 3 : 4-bis-(p-acetoxyphenyl)-3 : 4-hexane diol.

Patent GB-1039405-A (GB)
Title: Improved sulfoxidation process
IPC: C07C309/04
Filed: 1963-07-19
Abstract: Sulphonic acids are obtained by reacting on initiation by a free radical generator a nonaromatic hydrocarbon feed with excess sulphur dioxide and oxygen in a ratio of at least 2 mols. of SO2 per 1 mol. of O2 in the liquid phase, thereby forming sulphonic acids and small amounts of persulphonic acids, quenching the reaction mixture with water or an aqueous diluent, while maintaining the concentration of sulphur dioxide in the reaction mixture at a sufficiently high level to prevent any significant colour formation and recovering the sulphonic acids from the reduced mixture.  The reaction can be initiated by means of ultra-violet light, high energy ionization or chemicals such as azo compounds.  The following non-aromatic hydrocarbons may be used in the feed:-n-dodecane, n-pentadecane, n-octadecane, n-eicosane, n-docosane, n-tetracosane, n-triacontane, cyclododecane, cyclohexane, cyclo-octane, dodecene-1, octadecene-1 and polyethylene (see Division C3).  The molar ratio of oxygen to sulphur dioxide in the reaction zone is preferably about 1:5 to 10 and the molar ratio of oxygen to feed can be in the range 0.1:1 to 10:1.  If desired an inert diluent, e.g. nitrogen, may be present. For C12 to C24 hydrocarbons the sulphoxidation reaction can be effected at temperatures between 70 DEG  and 150 DEG  F. and at pressures of 40 to 80 p.s.i.g.  The reaction mixture can be kept under pressure until it has been reduced with water or an aqueous diluent, then the pressure is reduced to atmospheric pressure. Reference has been directed by the Comptroller to Specifications 810,574 and 912,903.

Title: Improvements in and relating to Internal Shoe Drum Brakes
Inventor: MARGETTS HUGH GRENVILLE
IPC: F16D65/56
Filed: 1967-06-21
Abstract: 1,191,115. Internal shoe-drum brakes. GIRLING Ltd. 14 June, 1968 [21 June, 1967], No. 28752/67. Heading F2E. In an internal shoe drum brake a pawl and ratchet mechanism 18, 19, Fig. 1, is operated to adjust the spacing between abutments 5, Fig. 3, against which adjacent ends of brake shoes 2, 3 bear, by pivotal movement of a brake operating arm 14 connected to a hand brake, the arm being pivoted on one shoe at 13 and connected by a strut 23 to the other shoe. The load applied to the ratchet and pawl mechanism is limited by a pawl actuating spring 20 engaged by the operating arm. In operation the arm 14 is pivoted clockwise by operation of the hand-brake to apply the shoes to the drum. This causes anticlockwise rotation of actuating lever 17 through a pin 15 on the free end of arm 14 which is engaged in a slot 16 in the lever 17 and maintained by the spring 20 at an end of the slot. Excessive rotation of the actuating lever causes the ratchet wheel to be engaged by the pawl 18 on the lever 17. The ratchet wheel is fixed on the end of a threaded spindle 7 engaged in a captive unit 8 so that when the ratchet wheel is rotated the spindle moves axially. Additionally the spindle is provided with cone 6 mating with opposed faces of the abutments 5 such that as the spindle is moved upwards the abutments are spread apart to reduce the shoe clearance. If excessive load is applied by the lever 14 to the adjustment mechanism, the spring 20 collapses to prevent this load being applied to the lever 17. The brake is also actuable by an hydraulic or mechanical actuator 4; in the embodiment of Fig. 1 in which the strut 23 is pivoted both on a brake shoe and the arm 14, automatic adjustment, as described above, occurs simultaneously, but in the embodiment of Fig. 2 (not shown), wherein the ends of the strut are bifurcated and slidable on the shoe and lever this adjustment does not occur.
