Title: Improvements in or relating to Electrically Operated Diaphragm Vibrators, particularly applicable for Signalling Devices in Factories and like Places.
Inventor: HARLOW CLARENCE BURR
IPC: G10K9/15
Filed: 1918-11-15
Abstract: 120,914. Harlow, C. B. Nov, 21, 1917, [Convention date]. Diaphragm vibrators.-In an electromagnetically operated diaphragm vibrator, the armature 9 is mounted on a spring disk 10 spaced from the diaphragm 3 so that, when the armature is released, it strikes the adjustable anvil 5. The operative movement of the armature closes the circuit through the contacts 25 whereby, after the armature strikes the anvil, it is immediately withdrawn by the electro-magnets, the contacts 25 being then free to move apart under the action of the supporting springs 22, 23. The triangular shaped laminated core 16 of the electro-magnet is carried by the bridge members 14 which carry also a condenser 20 connected across the interrupter contacts. The interrupter is connected between the two windings of the electro-magnet and is adjusted by means of a sliding member 31 connected to the screw 35.

Title: Proportional discharge control system
Inventor: BROMFIELD ALEC DESMOND
IPC: G05D11/13
Filed: 1962-05-15
Abstract: 966,631. Discharging material from a plurality of hoppers. STOTHERT & PITT Ltd. March 19, 1963 [May 15, 1962], No. 18753/62. Heading B8S. A plurality of hoppers discharge on to endless belt B and their discharge valves X are controlled by means of a uniselector. The passage of the rotating central contact of the uniselector from one fixed contact to the next corresponds to the time of operation of a predetermined discharge valve. It follows that the movement of the rotating contact over a series of fixed contacts will cause the operation of selected discharge valves from selected hoppers for selected times in a predetermined sequential order. This causes therefore a given quantity of material to be discharged from given hoppers on to a belt B. When a number of uniselectors are used, given quantities of materials from different hoppers may be discharged simultaneously on to belt B. In this way the discharge of material from the hoppers on to belt B may be made according to a fixed programme.

Work-holders.-The work clamp 15 is removably supported on four rods 14 extending from the body 11 and has a pair of transverse rods 27 on which jaws 28 are slidable against the action of springs 29 fitted between them. The jaws are operated by a hand wheel 34 on a right- and lefthand threaded shaft 33 engaging nuts 32 on levers 30 which are pivoted on links 31 and engage the jaws through rollers 35. An eccentric adjustment 37 for centring the jaws relative to the die-head is provided on the pivot for the links 31. Die-heads.-The die-head 18 is rotated by an annular gear 26 engaging a shrouded sliding gear 25a splined to the motor shaft 24 and consists of two parts, the front part 43 having four tangential guides for chaser mountings 53 and the rear part 41 being secured to the guide member 19. Guide pins 47 and a shorter pin 45 connect the two parts of the head through a plate 46 which is journalled on the forward part and has cam surfaces 52 engaging the chaser mountings. Initial adjustment of the position of the mountings in their slides is obtained by angularly adjusting the camplate 46 by adjusting a pin 49 in a slot 62; fine adjustment of the pin is obtained by a plate 50 and an eccentric 55 on the pin 45. Partial threads 63 in the chasers 40 and a worm 64 enable the chasers to be adjusted in their mountings and a plate 66 clamps them in position. The interchangeable threaded bush 21 on the guide member feeds the die-head along the tube a until it meets a stop and the front part 43 continues to rotate and move forward until the pin 45 disengages from the cam-plate 46 which is then free to be rotated by springs bearing on the pin 49, so that the chasers are opened. After the screw 22 has been disengaged, the die-head can be withdrawn by a hand wheel 56 which operates a pinion and rack. Removing burrs.-A conical cutter 60 fitted on the motor shaft 24 can be used for removing burrs from the end of the threaded tube.

Title: Dicyclohexyl alkyl phenols
Inventor: RICKERT HERBERT BOWERS
IPC: C07C39/17
Filed: 1957-06-20
Abstract: The invention comprises 2,6-dicyclohexyl-4-alkyl phenols of general formula <FORM:0802884/IV (b)/1> wherein X is cyclohexyl and R an alkyl radical of 2-5 carbon atoms.  The compounds may be prepared by reacting cyclohexene or cyclohexanol, which is capable of yielding cyclohexene with an alkyl phenol.  The reaction is carried out in the presence of a condensation catalyst such as sulphuric acid, hydrochloric acid, phosphoric acid, zinc chloride, or aluminium chloride, and an acid activated clay or a cation-exchange resin in the acid form. It is preferable to use at least two molecular portions of cyclohexene with each molecular proportion of alkyl phenol and an amount of catalyst equal to from 1 to 10 per cent by weight of the phenol.  The reaction is preferably carried out between 140-200 DEG  C.  The alkyl phenol and catalyst are mixed together and the cyclohexene added portionwise, whilst stirring the reaction mixture which is maintained at a temperature of 140-200 DEG  C.  The reaction mixture may then be filtered and the filtrate successively washed with dilute aqueous alkali metal hydroxide and water.  The filtrate is then fractionally distilled under reduced pressure. Examples are given of the preparation of 2,6 - dicyclohexyl - 4 - ethyl phenol, 2,6 - dicyclohexyl - 4 - isopropyl phenol, 2 - 6 - dicyclohexyl - 4 - secondarybutyl phenol, 2,6-dicyclohexyl - 4 - secondaryamyl phenol, and 2,6 - dicyclohexyl - 4 - normal butyl phenol.
