Title: An improved method of and installation for cold chamber refrigeration
IPC: F25D17/00
Filed: 1953-06-22
Abstract: 724,866. Refrigerators. SOC. D'ETUDES TECHNIQUES INDUSTRIELLES ET FRIGORIFIQUES, S. E. T. I. F. June 22, 1953 [Aug. 6, 1952], No. 17298/53. Class 29. A. refrigerated chamber for storage is cooled normally by air circulated by a fan over a refrigerated unit and over the exterior of the chamber and, when extra cooling is required, part of the air is diverted to flow through the chamber. As shown in Fig. 2, the air circulates in ducts around the chamber and enters a duct 11 extending along one top corner of the chamber. The air then passes down ducts 4 ... 6 which also pass under the floor of the chamber and up the other side wall to enter a discharge duct 12 extending along the other top corner. Auxiliary ducts 13 ... 15 join the ducts 11, 12 and cool the ceiling of the chamber. Ducts 11, 12 are subdivided into channels one feeding each duct 4 ... 6 and so dimensioned as to supply equal quantities of air. When further cooling is required the supply of air is increased either by speeding up the fan or by throwing in further fans and the increased pressure opens valves 9, 10 in each of ducts 41 ... 61 to admit the air to the chamber. The air re-enters the ascending parts of the ducts by similar automatic valves. the ducts may be throttled downstream of the valves 9, 10. In a modification, the top ducts 13 ... 15 are dispensed with and the ducts 11, 12 are constituted by a duct extending over the whole of the ceiling and divided by a longitudinal partition. The valves 9, 10 comprise, (Fig. 6), a flap 46 pivoted to the chamber wall 31 and so counterweighted at 49 as to be slightly open (dotted line position) when the fan is not running. When the fan runs at normal speed, the valve closes and, when it runs at a higher speed, the valve moves to the position shown to admit air to the chamber. Detailed description of the application of the system of ducts shown in Fig. 2 to a chamber is given with reference to Figs. 3 to 5 (not shown).

Title: Improvements in gauging apparatus
IPC: G01B13/00
Filed: 1944-09-11
Abstract: 596,641. Linear - dimension gauges. FAIRWEATHER, H. G. C. (Sandvikens Jernverks Aktiebolag). Sept. 11, 1944, No. 17324. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 26, 1945.] [Class 106 (ii)] [Also in Group XXIX] In a gauge having an indicating-device 14, 28 operated by a difference in pressure between two pressure chambers 2, 3 provided with restricted inlet passages 4, 5, respectively, connected to a common pressure source 6, the outlet passage 15 of chamber 2 is controlled in response to changes of some physical quantity, and the outlet passage 16 of chamber 3 is controlled in response to changes of pressure in chamber 2 in such manner that when pressure in chamber 2 increases, the pressure in chamber 3 decreases, and vice-versa. The chambers 2, 3 are connected to bellows 9, 10 wherein are wooden blocks 11, 12, the upper ends of the bellows being hinged to one common lever 13 centrally pivoted at 27 and connected through gearing 28 to the pointer 14. The outlet passages 15, 16 are controlled by valves 17, 18. The valve 17 is attached to one arm 19 of a bell-crank lever pivoted at 29, the other arm 30 being actuated against a spring 31 by a feeler &c. contacting a workpiece to be measured. The valve 18 is on a threaded spindle 21 carried in a member 23 having an arm 24 and supported by a plate spring 22 secured to the base 1 of the gauge. If the pressure in chamber 2 decreases due to outward movement of valve 17, the lever 13 turns counter clockwise, a cam 26 on the lever engaging an inclined face 25 on arm 24 then moves upwardly to allow valve 18 to approach outlet 16 so that pressure increases in chamber 3 and bellows 10, producing an additional counter-clockwise rotation of lever 13. Such additional rotation causes arm 24 to move further inwardly, so that the movement of the pointer 14 is magnified. The outlet passage 15 may be controlled directly by a work-piece. For example, a metal strip or a length of wire may be gauged by passing it across or through the passage, or a nozzle may be measured by attaching it to the passage.

Abstract: 480,779. Cathode-ray tubes. RADIOA,KT.-GES. D. S. LOEWE. June 26, 1936, No. 17804. Convention date, June 27, 1935. [Class 39 (i)] A cathode-ray tube preferably of the high vacuum type is provided with a diaphragm 1, an aperture in which is to be electronoptically reproduced on the fluorescent screen of the tube, the diaphragm having a potential which is near cathode potential (e.g. 100 volts positive relatively to the cathode when the anode potential is 2000 volts), and means are provided for producing between the diaphragm and electron optical system an accelerating field which is homogeneous and exempt from transverse components in those parts of the tube traversed by the beam. The homogeneous field may be produced by a tubular member 2, the diameter of which is large compared with the diameter of the beam and which is separated from the diaphragm 1 by a distance 18 of the same order of magnitude as the diameter of the member 2, thus providing a substantially field-free space between the members 1, 2, through which the electrons travel with the speed they possess on passing through the diaphragm. This is made as low as possible by providing a low potential on the diaphragm, the beam being maintained sufficiently intense by means of a screening grid 21 at higher potential and concentrated by a cylinder 22. Suitablepotentials, examples of which are given in the Specification, are obtained from tappings on a potentiometer 17. The homogeneous field may also be obtained by replacing the member 2 by a high resistance layer, one end of which may be connected to the potential of the diaphragm 1 and the other to that of the anode 3, while in a further form a helicallywound resistance layer may be used, one end being connected to the diaphragm and the other to the anode 3, a magnetic focusing coil being provided in the plane of the anode. Specification 442,511 is referred to.
