Title: Pivotal mounting
IPC: F16C11/04
Filed: 1974-06-19
Abstract: 1494343 Multi-position pivotal mountings ITW Ltd 18 June 1975 [19 June 1974] 27129/74 Heading E2F A pivotal mounting (particularly for the sun visor of an automobile) is formed from two one-piece plastics (e.g. nylon) parts: an outer sleeve 2 with a generally cylindrical bore 10, which is provided with a number of radial undulations 12 spaced around its circumference and an inner generally cylindrical member 13 with a number of radial undulations 20 spaced around the circumference of its outer surface; the number of undulations on each part being unequal. In the embodiment shown a fastener 6 is mounted in a hole in the vehicle body and secured by a pin 8, the interior of member 13 receives a sun visor. There are three projecting longitudinal undulations 12 and sixteen depressed longitudinal undulations 20 designed to provide fortyeight stable relative angular positions of the parts - only one of the projections 12 engaging centrally in a depression 20 at any one time. Either part can carry projections or depressions and there can be more undulations on the sleeve than on the inner member. In modified sleeves the undulations can be longitudinally as well as circumferentially spaced projections (Fig. 7 not shown), or can be helically arranged along the length of the sleeve (Fig. 6 not shown)-each with corresponding depressions on the inner member. In this latter case the hand of the helix is such as to maintain the parts together on relative rotation. Both sets of undulations can have ratchet-like profiles to make relative movement of the parts easier in one direction e.g. upward movement of the visor. The undulations can be arranged to provide even firmer registration at some points than others or a separate snap-fit catch could operate between the pivot parts at such points.

Filed: 1964-07-03
Abstract: 1,043,814. Photographic shutters. HATTORI TOKEITEN KABUSHIKI KAISHA. July 3, 1964 [July 3, 1963; March 25, 1964; June 5, 1964], No. 27613/64. Heading G2A. The blades of a photographic shutter also constitute the leaves of the iris diaphragm. The blades are preferably controlled by an escapement to move at a constant speed throughout the duration of the exposure, which is timed automatically by an electro-optical delay circuit (Fig. 5, not shown), and are closed rapidly at its end by electro-magnetic means. As shown, the shutter has two blades 1 pivoted at B and driven by a pin-and-slot connection with an opening member 3. The shutter is cocked by raising lever 15, which is pivoted at 13 and has projections 16 and 15a. The projections rotate members 10 and 4 to positions in which they are retained by pawls 17 and 6 respectively. On turning release trigger 29, pin 30 allows contacts 101 and 104 to close and operate a warning lamp if there is insufficient light for an automatically controlled exposure. Further movement of trigger 29 rotates pawl 17 to release member 10 whose initial rotation releases lever 24 from pin 16c to close contacts 100,103 and open contacts 100, 102. The delay circuit is thus brought into operation immediately before the escapement controlled rotation of member 10 allows pin 8 of opening member 3 to slide on cam profile 10b of member 10. The opening member 3 continues to rotate and open blades 1 until the delay circuit energizes electro-magnet 50. The exposure is ended by armature 52 retracting pawl 6 and allowing closure member 4 to engage projection 11 under spring action and close blades 1. For a manually controlled exposure at full aperture, the escapement is disconnected so that the rotation of member 10 is unrestricted. In another form, (Fig. 8, not shown) a multibladed shutter is controlled by blade rings operating as opening and closure members.

An arrangement for protecting a three-phase motor against incorrect phase rotation comprises a phase sequence network having two resistive limbs 10, 12 and a reactive limb 14. When the phase rotation is correct, the resistor 10 heats the bimetallic element 18 of a thermal switch 16 sufficiently to close contacts 18, 22 in the conductor L1. This completes the circuit for the coil 38 of a contactor 28 which closes its contacts 26, 32, 36. When the phase rotation is incorrect, the current in the resistor 10 is reduced and the switch 16 is not closed. In a modified arrangement, Fig. 3 (not shown), both resistors 10, 12 are associated with thermal switches which have changeover contacts operative to connect the motor to the conductors L1, L2. so that the phase-sequence applied to the motor is always correct; This arrangement may have the contactor 28 of Fig. 2 in which case protection is effected against over-voltage, under-voltage, and the open-circuiting of a; phase conductor.

Title: Method of separation of the boron isotopes
Inventor: CHEMLA MARIUS
IPC: B01D59/32
Filed: 1966-06-23
Abstract: B10 and B11 are separated by an exchange reaction between the vapour of a boric ester and a solution of a metal borate in a liquidvapour contact column, the boric ester flowing countercurrent to the solution of metal borate. The preferred boric esters are ethyl and methyl borate and the preferred metal borate is an alkali metal or alkaline earth metal, e.g. potassium or calcium borate which may be dissolved in a water alcohol mixture.  As shown, in Fig. 2, the exchange may be achieved by the countercurrent contact of the vapour and liquid in column 2, the vapours of boric ester emerging at the top of the column to be condensed in vessel 3.  The condensate produced is continuously hydrolysed with an aqueous alcoholic <PICT:1118533/C1/1> solution of an alkali, e.g. NaOH supplied from vessel 6 via pump 9 and the product of hydrolysis returned to the column.  If desired, part of the product may be withdrawn through tap 23.  The alkali metal or alkaline earth metal borate in alcohol solution received in flask 1 at the base of the column, maintained under continuous reflux, is acidified from vessel 7 by a continuous supply of phosphoric acid which liberates the boric acid to form, almost immediately, a fresh supply of ester for the exchange process. Part of the contents of the flask 1 may be withdrawn, when desired, through cooler 21 into vessel 15 where agitation with magnetic stirrer 17 and decantation lead to the precipitation in vessel 16 of unwanted sodium phosphate 18.  The supernatant liquor is returned by pump 19 through heaters 21 to the flask. Other methods of removing the sodium phosphate may be used.  Any required product which is said to be methyl borate, may be withdrawn through tap 24.  The raw feed liquor which may comprise natural boric acid in methyl alcohol is introduced through pipe 22 into the middle of the column.
