Abstract: 1397876 Comminuting apparatus CUMBERLAND ENG CO INC 24 April 1973 [26 April 1972] 19338/73 Heading B2A Apparatus for granulating thin plastics sheets comprises a feed table 4 Fig 2 with a cutter 28, 29 at the inner end and feed rolls 6, 8 at the outer end, a pivotable support plate 32 overlying the feed table, a pressure pad 54 with an outer edge pivotally attached to the inner end of the support plate 32, the inner edge of the pad being movable towards the feed table independently of motion of the support plate, a first resilient means e.g. 38 for holding at least the inner end of the support plate in proximity to the feed table and a second resilient means e.g. 60 for resiliently holding the inner edge of the pressure pad in a predetermined but movable position proxiimate the feed table. In one embodiment the pressure pad is held down by a safety gate 66. The system is controlled by a fluidic circuit which provides operator protection by interlocked operation of the safety gate. In a second embodiment the pressure pad is biassed downwards not by the safety gate but by auxiliary cylinders 94 which actuate the pressure plate 32 and cooperate with fingers 108 on the pressure pad 54, Fig 4. Biassing of the pressure plate may be done by a resilient toggle (114) using spring pressure Fig 7 (not shown), the presure pad being biassed by pressure cylinders (60) Fig 5 (not shown). The pressure pad 200 may be spring biassed Fig 10 (not shown). In a final embodiment cylinders 190, Fig 11 move a safety gate 194. The support plate 32 is biassed by a spring-toggle arrangement 114, The pressure pad 200 is also biassed by the spring toggle by arms 108 Fig 6 welded to the pad. The pad has a lip containing a filter block 204 wth an elastomeric strip 206 bearing against the safety gate. In all cases the feed rolls, pressure plate and pressure pad accommodate variations in thickness and maintain the sheet flat as it is cut by the rotor blades 29, which cooperate with a bed knife 26 Fig 11.

Abstract: 919,473. Mounting terminals. CAMBRIDGE THERMIONIC CORPORATION. June 9, 1959, No. 19732/59. Class 38 (1). A fitting suitable for use as a terminal assembly comprises a body 21 of a material having the characteristics of polyfluoroethylene polymers and formed with an axial recess 21.2 communicating with a cavity 21.3. An insert 22 having a stem 22.6 and flanges 22.2, 22.3 connected by a shank 22.1 is pressed into the body 21 by a tool 29, Fig. 4, the body being held under restraint in a jig 26, until flange 22.2 abuts the body and flange 22.3 enters the cavity 21.3. It is stated that the forcing of the insert into the body causes the material of the latter to flow round the insert and grip the same, the body retaining its configuration on removal from the jig due to lack of elasticity and flow at low pressures. A knurled portion 22.4 on the shank prevents rotation of the insert in the body. Fig. 6 shows another embodiment wherein the body 31 has an axial bore for receiving an insert 32 having stems 32.6, 32.7 at opposite ends of a shank 32.1.

Filed: 1947-07-25
Abstract: 639,418. Pneumatic conveyers. COLBURN, R. R. July 25, 1947. No. 20045. Convention date, March 30, 1945. [Class 78 (i)] A device for measuring and feeding batches of dry aggregates to a cement gun or the like consists of a pocket-wheel which is fed with the aggregates from a hopper, the batches being discharged from the pockets by a blast of compressed air to a grooved horizontal rotor from which they are fed by compressed air to the point of utilization. A hopper 12, Fig. 5, feeds aggregates to pockets 43 of a pocket-wheel 15 through an arcuate slot 24 in the bottom plate 23 of the hopper. The pocket-wheel is rotated slowly so that each pocket is filled in turn and then passes under an upper rubber plate 49 which seals the top. An aperture 32 in a lower rubber sealing plate 51 is situated diametrically opposite to the arcuate slot 24 and above this opens an inlet 26 for compressed air which serves, as a pocket 43 curves over the aperture 32, to expel the eontents of the pocket through a conduit 31, Fig. 4, into a horizontal feeding chamber. This chamber is provided with a loosely fitting agitating rotor 13 having a series of rectilinear grooves 33 into which increments of the batches fall and are conveyed round at a relatively high speed. A compressed air inlet 37 opens near the bottom of one side of the chamber and serves to blow out the aggregates into the outlet 41 to the point of use.
Patent GB-582764-A (GB)
Title: Production of acetylenic alcohols
IPC: C07C33/042
Filed: 1943-12-01
Abstract: Acetylenic alcohols are produced by reacting chlorinated unsaturated organic compounds of the general formula <FORM:0582764/IV/1> wherein R is a hydrocarbon radical or a hydrogen atom, R2 is an alkylene radical, X is a halogen atom or a hydroxyl radical and n is a positive whole number or zero, with a solution of an oxide or hydroxide of an alkali metal or alkaline earth metal of less than 50 per cent concentration by weight.  A preferred group of starting compounds is one in which the value of n is zero and these yield alpha acetylenic alcohols.  The many vinyl type chlorhydroxy compounds suitable as starting material for this process may be typified by the following non-limiting examples: 1-methyl, alpha and beta chlor allyl alcohols; 1,1-dimethyl, alpha and beta chlor allyl alcohols; 3-chloro, buten-2-ol-1; 1-methyl, 1-hydroxy, 3-chloro-butene-2; 1,1-dimethyl, -1-hydroxy, 3-chlorobutene-2; and compounds represented by the subsequent formul  in which n is a positive whole number. <FORM:0582764/IV/2> as well as their homologues and suitable substituted derivatives. When X represents a halogen atom in formul  I and II, it is replaced by a hydroxy group through basic hydrolysis.  Thus, 3-chlorocrotyl alcohol may be obtained from 1,3-dichlorobutene-2; 3-chloropentene-2ol-1 from 1,3-dichlorohexene-2; 2-chloropropene-2-ol-4 from 2,4-dichloropropene-2, &c.  Propargyl alcohol can also be produced by this process from the fraction of the by-products boiling between 104 DEG  C. and 157 DEG  C. formed in the production of allyl chloride via the chlorination of propylene. This fraction contains several three carbon atom polychlorides which may be used as starting materials.  It is desirable to withdraw the acetylenic alcohol as soon as formed, e.g. by conducting the reaction in a higher boiling solvent, thus in the production of propargyl alcohol, amyl alcohol and other high boiling alcohols and ethers may be used.  A solvent which boils below 115 DEG  C., for example dioxane, may, however, be used. In examples, 3-chlor allyl alcohol is refluxed with aqueous solutions of sodium hydroxide of 20 per cent, 10 per cent and 50 per cent concentration respectively.  The propargyl alcohol formed is extracted with diisopropyl ether and the yield increases as the concentration of alkali decreases, but an excess of 50 per cent alkali can be used when the reaction time is short.  Other solvents such as hydrocarbons which do not react with the reaction product, higher molecular weight alcohols, petroleum ether, methyl ethyl ether, methyl propyl ether, propyl isopropyl ether, &c. may also be used.  The products may be used to obtain their metallic derivatives or they may be hydrated to give solvents.  The Specification as open to inspection under Sect. 91 states that weaker basic acting compounds may be used under more strenuous reaction conditions.  This subject-matter does not appear in the Specification as accepted.
