Medicinal tablets.-Aspirin (acetyl salicyclic acid) to be formed into tablets with the addition of starch is first formed into a moist mass by the addition of a binding-agent such as resin, or gum dammar dissolved in a non-hydrolyzing solvent such as benzene, toluene, or xylene, and then granulated by passage through a sieve or otherwise. The use of a binding-agent such as gum dissolved in water or spirit is referred to, but is stated to result in the formation of free salicylic acid owing to hydrolysis. The process may be employed for the formation of tablets of any other substance deteriorated by water or other bydrolyzing-solvent.

Filed: 1946-05-01
Abstract: 611,480. Walls. HAYNES, H. W. May 1, 1946, Nos. 13236 and 31985. [Class 20(iv] A cavity wall to comprise the outer wall for a building, consists of inner and outer wall elements with spaced vertical pillars to which the elements are rigidly connected, disposed in the cavity, the outer element being spaced apart from the pillars to provide a continuous cavity around the building. To provide for a superimposed floor the inner wall may be interrupted so that floor supports may be secured to the pillars and the joint between the inner walls and the floor is then sealed. The pillars 1, consisting of steel tubes, or of concrete, stone &c. may be of telescopic construction, and rest directly on the foundation 15, being bonded thereto, in the case of concrete pillars, by an axial reinforcing rod 16. They are vertically disposed at suitable intervals between the outer wall 3 which may be of concrete, stone, brick, composition slabs &c., and the inner wall 2 which may be of plasterboard, wall-board, plaster on metal lathing &c. Secured to the pillars at spaced intervals are tie members 4 (Fig. 12), which are formed from flat metal strips bent to embrace the pillar and provided with nut and bolt 5a. The free ends 5 of the strip are twisted as shown and split to provide ragends to facilitate bonding with the outer wall, whilst the inner wall is secured by the extension 6 which may engage a vertical batten 2a. In a modification, Figs. 8, 9, 10 and 15 (not shown), the tie-member is of similar form but without the tightening means 5a. The construction is such that the outer wall element is spaced away from the pillars thus providing a continuous cavity 7 throughout the length of the wall. The inner wall 2 may be interrupted, as shown in Fig. 11, to provide for a superimposed floor, in which case the pillars preferably comprise steel tubes bolted together by welded-on flanges 25 which are embedded in the outer wall 3 on one side and on the other side serve as supports for the trimmed joists 27 carrying the subsidiary joists 28 and the floorboards 31 with which the upper inner wall is in close engagement. The cavity is then sealed by extending the damp course 32 as shown. In an alternative supporting arrangement, Fig. 14, the joists 27 are carried by steel brackets 25a passing through and welded into the tubular pillars, which in this construction may be provided in one length.

Abstract: 575,775. Cycle forks. WRIGHT, H. CLAYTON-. Aug. 18, 1943, No. 13432. [Class 136 (iii)] [Also in Group XXXII] A fork of a cycle or like wheeled structure has rubber or like resilient sleeves 4 arranged on lateral projections 2 on the crown 1 of the fork (or members fixed thereto) and an eyed end 5 on each fork blade 3 (or a member to which the eyed end is secured) is fixed on one of the resilient sleeves 4, the latter being fixed to the lateral projection 2 in a state of compression against the eyed end 5 so that the fork blades are held in position by the grip of the sleeves 4 and can oscillate by placing the sleeves 4 in torsion. Compression of the sleeves 4 is obtained by the tightening of a nut 8 which causes end portions 10 of the sleeve 4 to spread outwards, thus assisting lateral stability of the fork. The sleeves 4 may be hexagonal or otherwise not circular in section to coact with similar shaped surfaces on the eyed ends 5 and projections 2. Alternatively, recesses may be formed in these surfaces to give positive locking action. The sleeve 4 can be compressed during assembly between members 5 and 2 as described in Specification 553,085, [Group XXXII]. Instead of being secured by the nuts 8, the ends of the bolt 9 may be riveted over to maintain compression of the sleeve 4.

Abstract: 566,839. Hydraulic transmission of power. HYDRAULIC CONTROL ENGINEERING CO. Aug. 18, 1943, No. 13460. Convention date, Dec. 14, 1942. [Class 69 (ii)] A coupling comprises a housing 10 on the driven shaft carrying a ring gear 36 engaging pinions 54, 56 on a rotor carried by the driving shaft and adapted to pump liquid from a reservoir 62 in the rotor through a pressure responsive check valve 78 back to the reservoir. At low driving speeds the liquid passes through ports 88 in the valve and no drive is transmitted, but as the speed increases the pumps deliver more liquid to a common chamber 68 and the valve is forced back, against spring. pressure, until the port 88 is cut off. The pinions then become locked by back pressure and a solid drive is transmitted. Should overrunning occur, the pumps merely circulate liquid in the reverse direction. In a modification, the pumps deliver to the reservoir through separate valves 760, each loaded by light and heavy springs 862, 860, the latter of which becomes effective only after the valve has lifted from its seating in the rotor. In this case, if overrunning occurs, the valves close and pressure builds up in the reservoir and produces a braking effect.

Title: Improvements relating to material feeding and weighing apparatus
Inventor: GAMBLE JOHN ANTHONY
IPC: G01G23/36
Filed: 1961-04-18
Abstract: 1,000,792. Weighing apparatus. W. & T. AVERY Ltd. April 12, 1962 [April 18,1961], No. 13868/61. Heading G1W. [Also in Division G3] The invention relates to a weighing apparatus for maintaining a constant feed rate to a conveyer or for totalizing the weight of material delivered by a conveyer a section of which is supported by pendulum type weighing means. A load responsive disc element 15 (Figs. 2, 3) fixed to a collar 12 is rotated by a quadrant gear 10 on an indicator spindle 7 of the weigher and a gear 11 on the collar, between fixed "light" and "heavy" reference elements 17,16 respectively. The angular movement of the load element 15 and the indicator pointer (Fig. 1 not shown) is proportional to the deviation of load from the required load necessary to give a certain feed rate at a given conveyer speed. Elements 16,17 carry conductive segments X,Y spaced 90 degrees apart and load element 15 carries a conductive segment Z. A spider 19, on shaft 18 coupled to the conveyer drive, carries conductive collars 20 with brushes 22 insulated from the spider. Two adjacent pairs of brushes sense the position of segment Z relative to segment Y and the other two adjacent pairs sense the position of Z relative to X. In operation the degree of angular overlap of segment Z relative to X or Y is indicative of the amount by which the load is light or heavy. The speed of rotation of the brushes over the segments and hence the frequency of detection of the load variation is indicative of the conveyer speed. Elements 16,17 are connected through slip rings (not shown) to control grids of valves 23, 24 which energize relays when conducting to open or close by means of a motor a feed gate (not shown) on a hopper. It follows that the total period of conduction between Z and X or Y determines the degree of opening of the feed gate and can be used to control the feed rate of the conveyer. In an alternative embodiment (Fig. 4) instead of conductive segments the fixed elements carry centrally photo-electric cells 37, 38 which are activated by lamp bulbs on the spider arms, in dependence on the degree of overlap of a vane 31 on the load element 30 with respect to 90 degrees angular openings in the circumferential walls of the fixed elements. The speed of rotation of the lamps 39 and hence the frequency of detection of the length of a shutter gap is proportional to the speed of traverse of the conveyer. The total duration of the light responsive condition of one of the photo-cells e.g. 37 can be used to open or close the feed gate by an amount which will counterbalance any departure of the conveyer feed rate from its required constant value. When used for totalizing there may be only one fixed reference element and the electrical signals may actuate a counter. The position of the fixed reference elements may be adjustable to take into account Tare weight.
