IPC: B60Q3/04
Filed: 1967-10-13
Abstract: 1,249,463. Indicator lamps. SMITHS INDUSTRIES Ltd. 14 Oct., 1968 [13 Oct., 1967], No. 46767/67. Heading F4R. An indicator lamp comprises a casing containing at least two light sources and having a window through which light from the sources is emitted, each source producing two beams one of which is peculiar to the particular source and is visible over a relatively small area of the window and the other of which is visible over a relatively large area of the window. In the embodiment shown in Fig. 1 a plurality of bulbs 6 is located in respective compartments arranged around the periphery of a cup-shaped casing 1 and light from each bulb is emitted through a differently coloured filter 3 and an apertured mask 7. Light from any bulb also passes through a filter 5 of the same colour as the filter 3 and is reflected from a member 13 through a lens 11 of relatively large area. In a second embodiment (Fig. 2, not shown) the casing (20) contains a block (25) of translucent plastics material having cavities (26) in which the bulbs are located, each cavity being lined with coloured translucent material (27, 28). The front face (29) of the block is ribbed or frosted so that light incident thereon at an angle is diffused over a wide area, and each bulb therefor produces an intense beam of relatively small area immediately in front of its cavity and a less intense beam spread over the whole of the remaining face of the block. A third embodiment (Fig. 3, not shown) employs an L-shaped block (35) of translucent plastics material and the bulbs (34) are located in such a way that light from any bulb passes through an individual coloured filter (44) and also enters a chamfered surface (38) of the block to be diffused over the whole of the front face (41). In a fourth embodiment (Figs. 4 and 5, not shown) three bulbs are disposed in respective sector-shaped compartments in a cupshaped casing (50) and each bulb illuminates a respective aperture (54) in a mask (53) of smaller diameter than the casing. Light from each bulb also enters a clear plastics disc (56) covering the mouth of the casing through an annular filter (55) to give a wide-area beam. In a further embodiment (Figs. 8, 9, not shown) capless bulbs (120) are employed, each bulb being located in a respective compartment at the bottom of a casing and arranged so that light passes through the pinch (122) of the bulb and through an aperture in the bulb-holder to illuminate a corresponding aperture in a mask. Light from the bulb proper is reflected through a large window (112) at the top of the casing.

Title: Process for the preparation of solid white sodium stannate from technical sodium stannate liquor
Inventor: RUF ERICH
IPC: C01G19/00
Filed: 1969-09-23
Abstract: 1,220,009. Sodium stannate. TH. GOLDSCHMIDT A.G. 23 Sept., 1969 [2 Oct., 1968], No. 46875/69. Heading C1A. Solid white sodium stannate is prepared from technical sodium stannate liquor, by treating the liquor at a temperature above 40‹ C. with either potassium permanganate, 80-70% w./w. of the permanganate number of the liquor where the permanganate number is the number of milligrams of KMnO 4  which are reduced by one litre of sulphate solution to be treated, or an oxidation-equivalent amount of sodium hypochlorite. Solid material is separated from the liquor, and to the remaining liquor is added up to 0À1% w./w. of a mixture containing at least one sulphated oleic acid amide and one non- sulphated oleic acid amide, whereafter sodium stannate is precipitated by the addition of sodium hydroxide. Suitable sulphated oleic acid amides are the methylanilide of sulphated oleic acid and the dibutylamide or sulphated oleic acid, in each ease in the form of the corresponding sodium salt.

Title: Lru control systems
IPC: G06F12/12
Filed: 1976-11-11
Abstract: 1512596 Multi-level memory systems INTERNATIONAL BUSINESS MACHINES CORP 11 Nov 1976 [24 Dec 1975] 47057/76 Heading G4A The address of a LRU replacement block in a cache memory 7 is stored in LRU address circuits 11 for use when the next access attempt in cache is a miss. A chronology use value (register 22) is incremented for each access to a different block in the cache memory and the corresponding location in a chronology array having a chronology use value stored for each cache block is updated with the new use value. A cache miss also causes the chronology array to be searched to find the lowest use value and the corresponding block address to be stored in the CRU address circuits 11. The arrangement enables block replacement in cache 7 to be overlapped with identification of the LRU block to be used as replacement for the next following miss. To avoid loss of meaning in the use values stored in the array when the use value exceeds the maximum possible, before the maximum is reached (e.g. top two bits=11) a miss signal initiates the transfer to an alternative chronology array of all the stored use values with a right shift (e.g. of one bit) and the resetting of the current use value (register 22) to a value (e.g. 10 ... 0) exceeding all the modified use values in the alterative chronology array. The use of two chronology arrays alternately allow the read and write cycles to be overlapped. A block identified as the next to be replaced and which is accessed before it is replaced may retain its status as the LRU block (its use has been infrequent), or it may be redesignated as the MRU block (highest use value), a non-pagetransfer-overlapped LRU search then being necessary, or the next to LRU block address may also be stored in LRU address circuits 11 and be used for the replacement instead. Faulty cache blocks may be locked out by setting an additional bit in the active-chronology array during initial (micro) program load, the lockout bit being retained after shift transfer between the alternative arrays.

Filed: 1965-11-08
Abstract: 1,090,708. Labelling machines. PILOTCHAVENAY. Nov. 8, 1965 [Nov. 7, 1964; March 25, 1965], No. 47168/65. Heading B8F. A machine for applying labels initially mounted on a backing strip has a vacuum drum on which the separated labels are held for application to articles held in troughs of an article conveyer. Labels 37 on a backing strip 38 are separated therefrom as the backing strip is drawn round a device 9 by a cylinder 4 before being taken up on a cylinder 11. The labels are held by vacuum on a drum 5 until they contact articles 36, held in troughs 33 of an endless chain conveyer, the articles if cylindrical rotating during application. The parts are driven by a motor 10 and means are provided to synchronize the label and article feeds to ensure correct positioning of the labels. In a modification the backing strip feed provides a dwell period during which a printing mechanism can operate on a label still thereon. When flat articles are being labelled the peripheral speed of the drum and article conveyer are equal.

Title: Fluidic porximity sensor
IPC: F15C1/16
Filed: 1971-10-11
Abstract: 1374775 Fluid operated gauges BOWLES FLUIDICS CORP 11 Oct 1971 47321/71 Heading G1M A proximity gauge, Figs.1, 2, comprises a fluid inlet 9 in a block 1 and ducts 4 to cause air to vortex in a chamber 2. A sensing tube 11 has apertures 13 so that the air may also enter the tube and increase the static pressure inside the rotating helical jet issuing from the passage 7 so that the jet is increased in length and its range of detection increased. When the jet or vortical sheet as it is called is impeded the static pressure inside the sheet increases to indicate the proximity of an object to the sheet. Best results are obtained when the static pressure at restriction 12, in the absence of a detected object, is ambient and the pressure at the end of tube 11 is just slightly below ambient. In Figs.3 and 4 (not shown) the block 1 is surmounted by a further block (28) having a fluidic OR/NOR gate (29) which applies a quiescent bias pressure to a control passage (31) so that the static pressure in tube (24) is lowered and thus increases the switching sensitivity of the gate in response to object detection. In Fig.6 the sensing tube 67 has a tapered bore 71 communicating via chamber 73 and bleed channel 79 with vortex chamber 49. The bore 71 also leads to a chamber 81a having a diaphragm 83 pressurized on its otherside 81b and acting as a flapper valve which closes off or opens up a nozzle 85 connected to a back pressure gauge operating on the Venturi principle such as that indicated in Figs.10, 11 (not shown). If a device is to have a range between two limits then by passing the object under two proximity detectors it is possible to decide whether it lies within such a range.
