Title: Improvements in and relating to swing or like tray bakery units employed in the manufacture of tin bread and to means for loading and unloading such
Inventor: WALKER JOHN MCGREGOR
IPC: A21B1/46
Filed: 1949-09-22
Abstract: 700,974. Endless conveyers. BAKER PERKINS, Ltd. Dec. 19, 1950 [Sept. 22, 1949], No. 24347/49. Class 78 (1). [Also in Group XII] In a swing tray conveyer for an oven or other bakery unit having trays with upstanding guard lips along their front and rear margins, means are provided for effecting, at the discharging and/or charging station, a relative displacement between one or both of said lips and the tray bottom or tin support to eliminate temporarily the guard function of the lip or lips so that the tins may be transferred over a lip to or from a tray by a sliding action, the means further operating to reinstate the relative positioning of the lip or lips and the tray bottom or tin support after charging and/or discharging so that the guard function of the lips is restored. In the embodiment shown in Figs. 1 and 2, juxtaposed charging and discharging stations A and B are located on the upwardly running lip of the conveyer near the front of the oven, and, in order to allow the passage of the baking tins, as each tray 1 approaches these stations the front guard lip 4 is lowered by a rocking arm 17 which has a roller 20 urged against a cam plate 11 by a spring 21 and is formed with a toothed segment 16 meshing with a corresponding segment 15 mounted on the shaft 13 on which the guard lip 4 is pivoted. As the conveyer moves further the roller 20 travels round the cam 11 which is so set that said roller passes over the cam recess 23 as each tray approaches the discharging station. After the lip 4 is lowered, the tray is tilted by one or more pivoted arms 26 each having a roller 27 contacting either or both of the tray end plates 2 and the tins coming into contact with a fixed buffer are slid over the lip 4, pivoted flap 29, and shoot 24 on to a discharge conveyer or table 35. At the loading station A, charging of the tins from a belt 36 is effected by pusher gear 37, the tray being kept horizontal by a roller 32 on the end plate 2 engaging a guide rail 33 and as the tray leaves the loading station the roller 20 engages the concentric portion 22 of the cam 11 raising the guard lip 4. In a modification of the lip-operating means, Fig. 6 (not shown), the roller 20 is urged against the cam by a balance weight and a spring under tension and in a further modification of this, Fig. 7 (not shown), the toothed segments 15 and 16 are replaced by single levers. Another embodiment, Fig. 8 (not shown), comprises a tray tilting device wherein a roller on a rotating arm contacts a boss on each tray as it approaches the discharge station causing it to tilt and to discharge its contents, and also comprises provision for expansion of the tray conveyer by mounting the conveyer sprocket axle and the aforementioned rotating arm axle on arms pivoted to the oven structure, the two axles being interconnected by sprocket gearing and also by a distance link.

Abstract: 1382706 Measuring differential air pressures T I (GROUP SERVICES) Ltd 8 Aug 1973 [25 May 1972] 24651/72 Heading G1N To measure the distance between a nozzle 11, Fig.1, and an object 18 air is passed through the nozzle and the pressure in the supply pipe is measured. The air is supplied to both sides of a diaphragm 1 via pipes 8 and 15 and control orifices 12, 13, one side of the diaphragm venting to the atmosphere through a nozzle 16 identical to nozzle 11. The diaphragm moves until the pressure drop across the two nozzles is the same and the diaphragm position, which is sensed by inductor 20, is a measure of this pressure drop. The inductor is wound on a pot core 18 and co-operates with a ferromagnetic plate 2 on the diaphragm. A constant A.C. voltage is supplied to the inductor by generator 21, and is rectified at 22 for display at 24. The magnitude of the rectified signal varies with the inductance, i.e. with the pressure or the separation of nozzle 11 and body 18. In Fig.2 another construction of the differential pressure sensor is shown, a metal diaphragm 25 being used. The main air supply is through manifold 30 which. is connected to the upper side of the diaphragm by passages 32, 36, 37 and to the lower side by orifice 33. The upper side vents through nozzle 28 and the lower side is connected to the measuring nozzle (not shown) by outlet 34.

Title: Process for the preparation of di-isobutyl ketone (isovalerone)
Filed: 1956-08-16
Abstract: The invention comprises 2,6-dimethyl-2-ol-heptanone-4 and its use in the production of di-isobutyl ketone.  The 2,6-dimethyl-2-ol-heptanone-4 may be prepared by the aldol condensation of acetone and methyl isobutyl ketone, preferably in a molar ratio of about 4 : 1, in the presence of a solid or dissolved alkali, at a temperature not above 40 DEG  C.; diacetone alcohol is also formed.  The preferred temperature is 10-25 DEG  C. Solid alkalis specified are NaOH, KOH and Ba(OH)2, in a column or in suspension.  The resulting mixture may be concentrated in a distillation column, and then distilled at a temperature not above 100 DEG  C. in the presence of iodine or an acidic catalyst (e.g. dodecylbenzenesulphonic acid) to promote dehydration and yield a mixture of mesityl oxide and dihydrophorone (some acetone and methyl isobutyl ketone may also be formed), which may be continuously removed by steam distillation and fractionated to remove acetone. The fractionation residue forms two liquid phases, a lower aqueous phase and an upper layer containing mesityl oxide, dihydrophorone, methyl isobutyl ketone and water.  The upper layer can be catalytically hydrogenated directly or fractionally distilled, the resulting mesityl oxide and dihydrophorone being catalytically hydrogenated separately to methyl isobutyl ketone and di-isobutyl ketone respectively.  The hydrogenation is effected with hydrogen or hydrogen donors in the presence of hydrogenation catalysts; in examples isopropanol and Raney nickel are used.  The semicarbazone of 2,6-dimethyl-2-ol-heptanone-4 is mentioned.
