Title: Improvements relating to nuts for tie bolts
Inventor: SUTCLIFFE ALFRED
IPC: E04G17/065
Filed: 1952-04-02
Abstract: 733,784. Nuts; bolting. RAPID METAL DEVELOPMENTS, Ltd. April 27, 1953 [April 2, 1952]. No. 8348/52. Class 89(1). [Also in Group X] A nut 6, Fig. 3, is held in an elastic sleeve 8 either by the elasticity of the sleeve or by a bonded connection, and is tapped from opposite ends with right- and left-hand threads for engagement with bolts 5, 7, respectively. Shuttering panels 1, Fig. 1, are spaced and supported during the pouring and setting of concrete, by tie bolts 5,.having nuts 6 at opposite ends. Bolts 7 attach the panels to the nuts. After setting of the concrete, the shuttering panels are removed and the nuts 6 retrieved either by using a box spanner in a recess 12 in each sleeve, or by re-inserting bolts 7 and turning them until the nuts are unscrewed. If there is no bonded connection between the nut and the sleeve, the sleeve is removed after the nut, but if there is a bonded connection, they are removed together, and the recesses are filled with cement. Specifications 682,870, 682,916 and 733,775, [all in Group X], are referred to.

Title: Improvements in circuit testing apparatus
IPC: G01R31/02
Filed: 1960-03-10
Abstract: 940,142. Visible signalling apparatus. A. S. ERIKSSON. March 10, 1960 [March 12, 1959], No. 8423/60. Heading G4F. In apparatus for testing the continuity of a circuit, comprising an electromagnet and a battery, a make and break contact operated by the electromagnet serves in general as an audible signal, while a neon type lamp operated by the high voltage induced in the coil of the electromagnet at the periodic "break" of its circuit effected by the make and break contact, serves as a visible flashing signal if the circuit under test is continuous. The neon 3 (Fig. 1) is connected in parallel with the electromagnet 5 which is in series with a battery 4, make and break contact 2,output leads 18, 20 and thus the circuit under test. The neon 3 may be connected between one end of the electromagnet (Fig. 2 not shown) and the output lead 18 remote from the electromagnet 5. A further alternative uses a two way switch 21 (Fig. 3) so that when the switch is in the dotted position the operation is the same as for Fig. 1 but with switch 21 in the other posiare connected with the internal wiring by means of contact plates 34, 35 and an insulated clamp 36. Screw 37 serves to tighten the clamp against the leads and the contact plates and also forces tion, high resistance e.g. 50kc, circuits may be tested, the induced e.m.f. in this case flowing through the test circuit and then through the neon. The make and break contacts 8, 9 (Fig. 5), armature 7, electromagnet coil 6 and core 5, the neon 3 and battery 4 are attached to a baseplate 22 contained in a housing 24. The output leads 18, 20 the lower part 41 (Fig. 8) of the clamp against an outer conduit 31 of the output leads 18, 20 and an abutment 43 of the baseplate 22, thus preventing the output leads 18, 20 from being inadvertently pulled out of the apparatus and also preventing the ingress of dust and other foreign matter into the apparatus.

Title: Production of urethane polymers
Inventor: LANDA AXELROOD SEYMOUR
IPC: C08G18/08
Filed: 1965-02-26
Abstract: Solid polyurethanes in fine particulate form are produced by suspending a reactant in fine particulate form in an organic liquid medium and reacting the suspended reactant with a chain extender in liquid form or in solution, the reactant and the resultant polyurethane both being insoluble in the liquid medium, and the reactant being either a polyester or a polyether or a prepolymer obtained by reacting either the polyether or polyester with an organic polyisocyanate. The reaction medium may be a hydrocarbon e.g. pentane, hexane, hexene, heptane, octane, nonane, decane, undecane, dodecane, eicosane, cyclopentane, cyclohexane, cyclohexene and cycloheptane.  C6-C9 hydrocarbons derived from petroleum are preferred. The reaction may be performed in any of four techniques:- (1) The chain extender may be added to the dispersion of solid reactant with stirring.  (2) The chain extender may be added to the melt of the solid reactant prior to the formation of the dispersion. (3) A liquid dispersion of the solid reactant in the dispersant may be prepared and then cooled to solidify the solid reactant in particulate form.  (4) The solid reactant may be mechanically ground to provide particles of the desired size. The particles themselves or in admixture with a chain extender are then added to the hydrocarbon reaction medium.  The polyether may be linear, e.g. polyethylene glycol of M.W. about 6000 or branched, e.g. the sequential condensation product of ethylene diamine with propylene oxide and ethylene oxide of M.W. about 27,000, about 80-90% of the molecule being oxyethylene.  In a typical Example (1) a mixture of the tetrol formed by sequential addition of 1:2-propylene oxide and ethylene oxide to ethylene diamine and polyethylene glycol was melted and toluene diisocyanate added.  The resulting mixture was added to a mixture of n-hexane and lead naphthenate and allowed to react to produce a polyurethane of particle size 40-50 mesh U.S.S.

In joints employing a collector plate 1 of stamped metal, a pipe 2 with a flanged end 2a is held by the adhesive material 4 in a boss 3 with the flange 2a covering virtually all of the surface of the material or a rubber washer 5 interposed between the flanges and the boss. In joints employing a collector plate of mouldable material, the adhesive material extends throughout the plate thickness, and is protected by flaring of the pipe end, a rubber or plastics washer or plate, or an 0-ring. Alternatively a layer of varnish, paint, synthetic resin is sprayed or brushed over the adhesive material for protection. The adhesive material is also used to attach the collector plate to a water box.

Title: Improvements in or relating to Telegraphic Relays.

IPC: H01H53/015
Filed: 1916-09-18
Abstract: 124,632. Withers, J. S., (Cox, K. C.). Sept. 18, 1916. Receiving systems and apparatus; relays, moving-coil; repeating systems.-The coil of a moving-coil relay of a receiving or repeating system is maintained in its inoperative zero position by spring - controlled contact arms which are connected to the coil through bell-crank levers and rods. The contacts are mounted on a spring-mounted block movable between two fixed extensions on the arm; while the core is made in two parts and with the coil and contact mechanism is mounted slidably between the magnet poles. Chattering of the relay is avoided by the provision of a strong magnetic field and by shunting the coil, or by means of a dash-pot. When the relay operates one contact a plain stop takes the place of the other arm and its lever and rod. The relay may be provided with a siphon recorder. In the arrangement shown in Figs. 1, 2, and 3, a moving-coil' 1 is provided with an arm 3 connected to a spring-controlled contact lever 11 through a rod 7 and bell-crank lever 9 and to a spring-controlled contact lever 12 through a rod 8 and a bellcrank lever 10 so that normally the springs 17, 18 of the levers 11, 12 hold the coil 1 in its zero position shown. The lever 11 carries contacts 28, 29 mounted on a block 30 which is mounted on a leaf spring 31. The block 30 is given a slight play between two projections 32, 33 of the arm 11. The arm 12 is provided with similarly mounted contacts. The spring-mounting of the contacts 28, 29 prevents the contact 29 leaving its contactstop when the momentum of the coil 1, during its return to zero position under the action of the spring 18, causes the coil 1 to move slightly beyond its zero position. The core 19 of the coil 1 is made in two parts rigidly connected, and the core is connected to two pieces 21, 22 sliding between the poles 2. The piece 21 carries the supports 23, 24 of the spindle 20; while the piece 22 carries the contacts and contact mechanism. The relay C may be employed in a repenting system comprising the selenium cell magnifying apparatus A described in Specification 399/14 and the moving- coil relay B described in Specification 121,489, or the relay may ba directly controlled by the selenium cell magnifying apparatus. In the arrangement shown in Fig. 4, the magnets 70, 71 of a sounder relay D are normally energized by a battery 72. The relay D controls the energization of the magnets 79, 82 of a sounder repeater E, an interpolator being inserted, if necessary, in the circuit of the battery 78 to break up the block signals. The relay C may be provided with a siphon recorder 62.
