Title: Improvements in or relating to rice cleaning and polishing machines
IPC: B02B3/02
Filed: 1954-03-26
Abstract: 759,072. Cleaning and polishing rice. ZAN, T. March 26, 1954, No. 8938/54. Class 58. A machine for cleaning and polishing rice comprises a frusto-conical rotor 1 rotatable within a casing having a perforated inner wall 2 and an outer wall 3, and an adjustable triangular sectioned ring 16 for controlling the amount of cleaned and polished rice leaving the annular space between the rotor and the inner wall 2. The ring may be supported on four sets of double wedges, one wedge 20 of each set being fixed to the base of the ring, the other wedge 21 of each set being fixed to the base of the inner wall 2. The ring can be turned on the wedges, e.g. by a handle 19, and thus raised or lowered to vary the width of the outlet from the annular space. Dehusked rice is fed into the machine through an inlet 11 in a top cover. Cleaned and polished rice passes from the annular space into a funnel 14 provided with an outlet 15. Rice meal passes through the perforations in the inner wall 2 into the space between it and the outer wall 3 and is discharged through an outlet 13.

Title: Improvements in or relating to polymerization of ethylene
Inventor: LENNEY EDWIN JAMES
IPC: C08F10/00
Filed: 1966-03-01
Abstract: In a process for polymerizing ethylene in an extended polymerization zone in the presence of a free radical catalyst and a telogen, the ethylene to be polymerized is provided in two portions the telogen concentrations of which are adjusted so that the concentration in the first portion is higher than that in the second portion, the first portion is heated to a temperature sufficient to initiate the polymerization of the ethylene, and the second portion is injected into the first portion at successive spaced points along the polymerization zone so that the telomer concentration in the first portion is maintained substantially constant.  The first portion may be recycle ethylene and may be heated to 120 DEG  to 190 DEG  C., and the second portion may be cooled to 0 DEG  to 50 DEG  C. and injected at 2 to 10 successive points.  The catalyst may be lauroyl peroxide, di-t.-butyl peroxide, diisopropyl peroxydicarbonate, diethyl peroxide, dimethyl peroxide, t. - butylhydroperoxide, azodiisobutyronitrile or acetoxime, and may be dissolved in a hydrocarbon solvent.  The telogen may be methane, ethane, propane, butane, butene-1, butene-2, cyclohexane or hydrogen. Apparatus suitable for carrying out the process of the invention is described and illustrated, and in an example ethylene is polymerized in the presence of butane using as catalysts t.-butyl peracetate, t.-butyl perbenzoate and a mixture of t.butyl perbenzoate and t.-butyl peroxide, dissolved in benzene.

Title: Radio frequency resonant circuit
Inventor: MANWARING JOSHUA GEORGE DOWELL
IPC: H01P7/00
Filed: 1963-03-08
Abstract: 1,040,322. Tuned structures. RADIO FREQUENCY CO. Inc. March 8, 1963, No. 9399/63. Heading H1W. [Also in Divisions H3 and H4] A tuned circuit comprises a stack of one or more pairs of plates so shaped and disposed that mutual inductance between the plates is provided by currents running in opposite directions along paths in opposed plates displaced from each other in a direction parallel to the plane of the plates. To this end, as shown in Fig. 1, the plates 20, 30 are provided with slots 24, 34 extending from opposite edges in such a manner that the current paths in the two plates are mutually displaced. The slots are near one edge of the plate and the plates are connected together in the vicinity of this edge so that opposite currents form in the two plates from terminals 26. A generator and a load (e.g. a high-frequency heating device) are connected between the common terminal 26 and terminals 28, 38 on either plate remote from the common terminal. Other configurations of plates may be used, some (Fig. 9, not shown) having slots which do not extend to the edges of the plate. A multiple arrangement (Fig. 6, not shown) comprises three pairs of plates with corresponding members of all pairs connected by conductors 56, 58. The load L is connected to an extra plate 62. In such an arrangement the capacitances between the pairs of plates are in parallel, as are the inductances. Hence an advantageous increase in the total capacitance of the device may be obtained. The capacitance may be adjusted by moving the plates relatively to each other, e.g. by altering the spacing or by rotating alternate plates about the earthed conductor 60. A further method of adjusting the reactance of the plates utilizes an adjustable conductor in one of the slots 92. An adaptation of the device to a push-pull output is described (Fig. 10, not shown).

Abstract: 490,920. Gas - purifying processes. BRANDT, R. March 29, 1938, No. 9539. [Class 55 (ii)] In the removal of carbon monoxide from combustible gases, such as coal gas, by steam catalysis preceded by purification of the gas by passage with oxygen over iron purifying masses, damage of the catalyst used in the steam catalysis by the oxygen still remaining in the gas mixture is inhibited by combustion of the oxygen at a preliminary catalyst of different composition from the main catalyst used for the carbon monoxide conversion. The preliminary catalyst specified comprises copper platinum, palladium, nickel, or metal oxide and the main catalyst iron-chromium. Sufficient oxygen may be admixed with the gas to give a rise in temperature of 40 to 60‹ C. at the preliminary catalyst, the gas being firstly preheated by heat exchange with the converted gas for example to 290‹ C., a temperature of 350‹ C. resulting before the gas is subjected to the steam catalysis.
