Title: Improvements in or relating to puffing of cellular products
IPC: A23L1/00
Filed: 1949-04-25
Abstract: A method of puffing or expanding cereals comprises removing air from the cereals by placing it under vacuum in an atmosphere of steam, increasing the steam pressure, and then suddenly reducing the pressure below atmospheric, the pressure drop being sufficiently great to expand the cell walls beyond their elastic limit.  Rice, or other cereals, are first freed of air and, whilst under the vacuum, flavouring, sugar, salt, vitamins, or nutritious salts may be added by atomising water containing the desired ingredients in the vacuum. The cereal is then cooked for 5-6 minutes at 20 lb. per square inch steam pressure, after which the steam pressure is raised to 90-100 lb. per square inch and suddenly reduced to below 8 in. mercury, and preferably to 0.1 in. mercury, to expand the cereal particles.

IPC: C01B33/193
Filed: 1967-03-10
Abstract: 1,178,477. Silica pigments. O. W. BURKE. 10 March, 1967, No. 11488/67. Heading C1A. In a process for making silica by the acidulation of an aqueous solution of an alkali metal silicate with carbon dioxide, electrolyte-free water is added to the solution during that period of the acidulation in which x in the formula for the alkali metal silicate M2O(SiO2)x (M = alkali metal) has become greater than 3À75, the proportion of water added being 10-150 parts per 100 parts of water present just prior to the addition. The network size of the particles or the floc size may be thus controlled by choice of the stage of acidulation at which the water is added. The addition of water may be started or ended at the appearance of a Tyndall effect (denoting specific values of x), or may be ended when precipitation is substantially complete (about 70% stoichiometric quantity of CO2 added). Alternatively, water addition may be continued after substantially complete precipitation of silica. The process may be operated continuously or batchwise, on alkali metal, e.g. sodium silicate solutions of concentrations e.g. 20-200 g/l., at temperatures of e.g. 5-200‹ C. or more.

Title: Improvements in electric-relay counting chains and selectors
Inventor: JOHNSON BENJAMIN BERTIE
IPC: H04Q3/00
Filed: 1949-05-02
Abstract: 689,736. Automatic exchange systems. TELEPHONE MANUFACTURING CO., Ltd. April 28, 1950 [May 2, 1949], No. 11724/49. Class 40 (iv). A relay selector comprises a chain of counting relays in which two relays are energized together momentarily, a test relay being connected on one side to like electrodes of two rectifiers, the other electrodes of which are presentable to two test wires corresponding to the energized relays, whereby the test relay can operate if the appropriate potential is presented through either rectifier. A group of final selector comprises ten " bar-relay " switches, one of which is shown in Fig. 2, and a relay selector, Fig. 1, the latter responding to a first train of impulses to select a numerical group and then either to a second train to select a particular line in the group or in response to the idle or busy condition of lines successively presented to a test relay. The first operation of contacts a1 energizes B which operates C. Impulses then restore and re-operate contacts a1, the first impulse energizing SR1 which locks up, FP pulling up at the end of the impulse. Subsequent impulses energize successive relays SR2 and so on, the preceding SR relay falling back at the end of each impulse. The SR relays control a register (not shown). The sixth impulse additionally energizes CH to distinguish between the two levels of Fig. 2. At the end of the train, when contacts a1 remain operated, C falls back slowly to release FP and the last operated SR relay, and to operate R, RA (not shown) in the register. R in conjunction with one of contacts m-q energizes one of elements FM1-FM5 in the manner described in Specification 689,735, the selected element operating a bank of contacts in each selective relay unit. With all SR relays restored, C re-energizes to re-operate SR1. One of wires P11-P51 or P61-P01, say P51, depending on which element FM is operated applies +ve or - ve potential to relay H, indicating that the outgoing line is busy or free, respectively, relay H operating if the line is free and locking up through HA. Contacts h2 then prevent operation of further SR relays, while SR1 holds up over ha6. If the line is busy, H does not pull up and SR2 energizes to release SR1, both being operated at the same time momentarily but rectifiers MRB, MRA preventing any short-circuit between them if the line newly tested is free, while H can still operate before SR1 releases.
