Title: Improvements in or relating to a method of making anhydrous monocalcium phosphate and in products containing the same
IPC: C01B25/32
Filed: 1938-08-30
Abstract: 518,737. Baking-powders. STEVENS, A. H. (Victor Chemical Works). Aug. 30, 1938, No. 25391. [Class 49] [Also in Group III] Orthophosphoric acid and lime are mixed under such conditions of concentration, hydration, and temperature as to produce a reaction temperature in excess of 140‹C., and the reaction is controlled to maintain a temperature above 140‹C., but insufficient to form substantial amounts of pyrophosphate, until a dry mass of minute' crystals of anhydrous monocalcium phosphate is produced. The product may be mixed with a moisture-absorbing filler such as starch, and is used in baking-powders and self-rising flours. The lime is used in slight excess, or alternatively any excess acid may be neutralized by addition of calcium carbonate. The preferred acid strength is 54-65‹ BaumÚ. The impurities in the phosphoric acid, particularly alkali metals are useful in promoting the stability of the product to hydration. The lime may be all quicklime, or the last portion added may be slaked lime. The preferred reaction temperature is 160-175‹C. Specification 518,738 is referred to.

Sept. 22, 1937, No. 25767/36, [Classes 145 (i) and 145 (ii)] Wood, especially in the form of heavy laminated sheets, is pressed, bent, or veneered by enclosing the work 17 and a former 16 into a closable rubber sac 12 which is placed in a pressure-resistant container 11 and evacuated, either prior to or after insertion in the container ; fluid pressure and, if necessary, heat is applied in the container to the sac and its contents, the sac being subsequently withdrawn without releasing the vacuum in it until the work has set, so that a fresh sac may be placed in the container. In the apparatus shown in Fig. 1, a central stiffening board 13 carries on either side base-boards 14, 15 on which are mounted shaped formers 16, 18 over which the work 17 is to be bent. The whole are placed in a rubber sac 12 the end of which is closed by a channel clamp and rod, the sac being then slid into a container 11 on planks 23 mounted on ball-races. The sac is evacuated through a hose 22 either before insertion in the container or subsequently, in which latter case, the evacuation may take place simultaneously with, or subsequently to, the admission to the container of air under pressure from a pipe 28. The container 11 may be fitted with a steam or electrical heater. Fig. 3 shows a modification in which the sac is formed by upper and lower rubber membranes 35 the margins of which are held in grooves in frames 32 by rings 34 ; rubber bands 33 on the meeting faces of the frames forming an air-tight joint between them. Holes and grooves in the boards 13, 14, 15 put all parts of the space in the sac into communication with the pipe 22. In a further modification, the sac consists of a single membrane carried by a frame, the under face of which makes air-tight content with a flat board forming the bottom of the sac.

Abstract: 665,421. Automatic steering systems. BENDIX AVIATION CORPORATION. Oct. 14, 1949 [Jan. 7, 1949], No. 26486/49. Class 38 (iv). In an automatic steering system such as that described in Specification 662,831, the maximum rudder movement is limited by a discriminator amplifier and associated relays, which disconnects from the servo-amplifier the normal compass heading signal, while it exceeds a predetermined value and injects a fixed signal in the correct sense and of the selected limiting value. As shown, a heading signal from an inductive pick-off 18 associated with the master direction indicator 11 is applied to the rudder amplifier 23 together with opposing rate of turn and displacement signals from pickups 41, 32 in known manner. The heading signal is also applied together with a reference voltage to a twin-triode phase discriminator valve 62 feeding a pair of valves 67, 70 which are biased so as to be non-conductive until the incoming signal exceeds a predetermined value. Application of a large signal causes one of these valves to conduct according to the sense of the signal and energize " left " or " right relays 49, 50 to disconnect the heading and rate-of-turn signals from the rudder amplifier, and connect in the correct sense the output of an inductive device 51 which may be set by a hand control 109 to the required maximum value.
