Title: Improvements in or relating to circulation-indicating devices for the cooling liquid, or lubricant, of internal combustion engines
IPC: F01M11/10
Filed: 1931-04-20
Abstract: 364,972. Lubrication indicators. SULZER FRERES SOC. ANON., Winterthur, Switzerland. April 20, 1931, No. 11607. Convention date, May 12, 1930. [Class 12 (iii).] A circulation indicator 12, applicable for indicating the flow of lubricating oil, is described with reference to the cooling water system of an internal-combustion engine. The indicator is actuated electrically from the same battery 20 which drives the circulating pump 5, when a switch 14 is closed by pressure in a circulating pipe 7. The action of the indicator, which may be optical or acoustical, is thus not affected by frost.

Title: Improvements in and relating to the casting of metals and alloys
Inventor: PARLANTI CONRAD ANTHONY
IPC: B22C9/10
Filed: 1950-05-10
Abstract: 733,681. Moulds; cores. CARRON PARLANTI, Ltd. May 10, 1951 [May 10, 1950], No. 11623/50. Class 83 (1). Mould and core materials.-An aluminium mould for casting metals has its casting cavity anodized and lined with a refractory coating. The pouring header is comparatively large, the ratio of the volume of the header to that of the casting being between 1:1 and 10 : 1 for casting aluminium and between 1:3 and 5:1 for casting iron or steel. A mould for casting a turbine blade 2 with a root portion I comprises casting cavities 3, 4 fed by a header 5 which, like the cavities 3, 4, is anodized and then coated with a refractory powder as by spraying a suspension of mineral silicates. The mould may have external pins 8 to assist cooling. Fig. 6 shows a mould for casting a blade with an intermediate mass along its length, the cavity 9 for forming the mass being connected directly with the header by a runner 10 and with a sub-header 11 providing a reservoir of molten metal. A mould for forming hollow articles, Fig. 7, has a core 13 also of aluminium which may also be anodized and given a refractory coating. After casting, the heat of the cast metal causes the core to melt. The time before melting occurs may be controlled by extending the core beyond the mould and providing the extension with cooling fins. Specification 543,577 is referred to.

Title: Improvements in or relating to television systems
IPC: H04N11/12
Filed: 1953-04-28
Abstract: 724,593. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 28, 1953 [May 1, 1952], No. 11707/53. Class 40 (3). In a multiplex system for the transmission of television images which are scanned line by line, the system employing a main signal and a plurality (k) of supplementary signals each comprising an auxiliary carrier wave and one or two complete or partial side bands and lying within the frequency band used for the main signal, the frequency band of each of the supplementary signals coincides wholly or in part with the frequency band of the other signals and the auxiliary carrier waves have frequencies which are respectively (n m  + m/1+k) times the line frequency where n m  and m are integers and m equals 1, 2, 3 ...k. Thus in a three-colour system employing a wide-band main signal made up of the green low frequencies and the high frequencies of the three colours together with two narrow-band supplementary signals corresponding to the red and blue low frequencies, the signals are multiplexed as shown in Fig. 3, in which the main signal extends over the band o-fa and the supplementary signals are modulated onto sub-carriers fh 1  and fh 2  and disposed with their side-bands overlapping. In accordance with the invention, one sub-carrier has a frequency (n 1  + )1/3 times line frequency and the other a frequency (n 2  + 2/3) times line frequency. With this arrangement, each signal contains interference due to the two other signals, but owing to the choice of sub-carrier frequency such interference is 2/3" radius out of phase with the interference in the preceding image and cancels visually after three images. Figs. 4 and 5 (not shown) illustrate a transmitter and receiver for such a system. Fig. 6 illustrates the application of the invention to a stereo-colour system employing a main signal and five supplementary signals modulated onto sub-carriers f 1  ... f 5 . In this case the interference between signals is compensated visually after six images.

Title: Improvements in scratch strain recorders
IPC: G01B5/30
Filed: 1956-04-17
Abstract: 783,842. Strain-recording apparatus. PREWITT, R. H., and LAHSON, M. April 17, 1956 [May 27, 1955], No. 11713/56. Classes 106 (2) and 106 (4). A scratch strain recorder comprises a crystal 22 for scratching a record of successive strains in an associated structure on a record sheet 28 which is moved in one direction only as a function of successive strains in one sense in a series of successive strains in alternate senses. Separate parts 11, 12 of a base plate and another plate 50 are secured to a structure in the regions A, B and C. Before mounting, these plates may be rigidly bonded together by a layer of soluble material 60 which is removed after mounting with a suitable solvent. The part 11 carries an arm 17 for the crystal 22 and the part 12 carries plates and brackets .constraining the record sheet 28, preferably of thin sheet metal, for transverse sliding movement, which is imparted thereto by spring brushes 56 mounted on the plate 50. Under compression loads relative displacement of the plates 12, 50 causes the brushes 56 to bite on the edge 38 of the sheet 28 and displace it, while when the stress changes under a tension load the brushes 56 slide back along the edge 38 while springs 35, 36 secured to the plate 12 bite on the edge 38 and prevent movement of the sheet 28. Thus a microscopic record, Fig. 10, of the stresses in the structure will be scratched by the crystal 22 on the sheet 28 which will be safe from fire and suitable for use on aircraft parts. The sheet 28 may be of silver-plated copper and its transverse movements may be reduced by securing the plate 12 to the structure in the area B<SP>1</SP> and when this is done the recorded displacements can be increased by eliminating the anchorage in the area B. Record strips of different widths may be used according to the nature of the stresses expected.

An overhanging portion 26 of the member 1 protects the pin 23 from accidental displacement. A screw plug 27 in the end of the member 1 is screwed down upon the member 2 to lock the hook in the closed position.

April 17, 1935, No. 11908. [Class 38 (ii)] A rectifier circuit arrangement for supplying operating D.C. potentials to thermionic valves comprises at least one series loop circuit including two transformer windings S1, S2 and two rectifiers R1, R2 in series, the rectifiers being connected in opposite directions in the loop circuit and being interposed so as to alternate with the transformer windings, A.C. potentials being supplied to the circuit through the windings S1, S2 in a direction which is additive around the loop and D.C. potentials being taken off from diametrically opposed points on the loop. The diametrically opposite tapping points may be either at the ends or anywhere on the transformer windings S1, S2. The rectifiers may be diodes or metal rectifiers. When the D.C. output taps are not at the centres of the windings S1, S2 these windings should be arranged on the same core to balance unidirectional flux components. In a modification, several loop circuits are connected together in " ladder " form, secondary winding S2 forming one winding of a further loop including two rectifiers and a transformer winding which itself forms one winding of a still further loop circuit. By this means the output terminals provide a plurality of progressively increasing D.C. potentials. Where the output connection points are not at the centre of the transformer windings, the " outer " two windings of the " ladder " are wound on the same core to avoid flux unbalance. A modification for use with three-phase A.C. supply is also described.
