Title: Improvements in and relating to apparatus for testing materials
IPC: G01N3/06
Filed: 1935-12-24
Abstract: 462,569. Testing physical qualities of materials. RESEARCH ASSOCIATION OF BRITISH RUBBER MANUFACTURERS, PORRITT, B. D., and SCOTT, J. R. Dec. 24, 1935, No. 35732. [Class 106 (ii)] A tensile testing machine is equipped with a suitably shaped piece of flat material A on which is marked a scale or scales co-operating with a load-indicating pointer, each of which is graduated for a particular stress, and in terms of the cross-section to ensure a particular stress being applied. In cases where the specimen is stamped out from sheet material the thickness may be taken as representative of the cross-section, and in cases of specimens of uniform section and length of the same density, for instance of the same material, the weight may be taken as proportional to the cross-section. These scales B, C, D, E, in the example shown are arranged on a machine for testing ring-shaped specimens of vulcanized rubber when the load is indicated by a loaded pendulum arm G carrying a pointer H. Using a specimen of which the cross-section, thickness, weight or other variable in which the scales are graduated, is " X " units, it is necessary only to observe when the pointer passes over the graduation " X " on each scale in turn in order to determine the moments when the stress on the specimen reaches each of the predetermined values for which the scales are graduated.

Title: Method and apparatus for compression coding of a pxq array of boolean coded points
IPC: H03M7/00
Filed: 1976-08-31
Abstract: 1507234 Data transmission INTERNATIONAL BUSINESS MACHINES CORP 31 Aug 1976 [29 Sept 1975] 36048/76 Heading H4P In apparatus for the compression coding of a pxq image array of sample points constituted by twovalued (black/white) picture elements, the sample points are serially applied in consecutive raster scan lines to the apparatus which, in response, simultaneously forms two matrices respectively representing a pxq array of high-order predictive errors and a pxq array of location events (such as raster leading edges of all the objects in the image). The more efficient of two methods for encoding the position of errors in the prediction error array is then selected to achieve improved compression. Thus, means are provided for counting run-lengths C between consecutive pairs of errors in the predictive error array, and means responsive to each predictive error operate to variable-length encode the most efficient of a first codeword and a second codeword, or in the absence of a first codeword, to encode with the second codeword. The first codeword is formed upon there being an unambiguous correlation between a prediction error in the i<SP>th</SP> scan line of the prediction error array and a location event in the i<SP>th</SP> or i<SP>th</SP>- 1 scan line of the location event array within a predetermined number of picture element positions from the prediction error. The second codeword is formed from the run length C between a prediction error and the preceding prediction error in the same scan line. The Specification explains how the use of the first and second codewords in combination enables both the number of codewords and the average codeword length to be minimized, resulting in improved compression.

Abstract: 1516995 Grinding machine control SEIKO SEIKI KK 2 Sept 1975 [3 Sept 1974 25 Oct 1974 28 Oct 1974] 36109/75 Heading G3N [Also in Division B3]  A grinding machine, e.g. a centerless internal grinder 1, effects a comparison between the actual rate at which a grinding wheel 4a removes material from the workpiece W and a predetermined material removal rate. The difference controls the relative infeeding movement of the workpiece and wheel to reduce the difference to zero using servomotor 7. Detector 8 continuously measures the inner diameter of workpiece W while it is being ground and clock pulses from generator 11 are used so that one signal from the size detector 8 at a first clock pulse is subtracted from another signal from detector 8 at a second clock pulse to give a signal related to material removal rate, which is compared with a rate set in circuit 14 in differential amplifier 12 and the result fed to servo-controller 15 which controls motor 7. Schmidt trigger 16 generates outputs P 1 , P 2  when respective predetermined workpiece diameters are detected to stop or reverse table feed or to start finishing grinding. Detector 17 measures wheel spindle power consumption which is proportional to tangential grinding force and this is compared with pre-set values 18 in circuit 19. The wheel grinding ability decreases with each cycle so that, when power consumption reaches a certain value, a circuit passes a signal via circuit 13 to cause the differential amplifier to reduce the predetermined material removal rate. After a certain reduction, the wheel must be dressed. Other embodiments Figs. 3 - 6 (not shown) are concerned with the changeover between rough, fine and finish grinding.

Abstract: 1414369 Alkali metal polyphosphates RHONE-PROGIL 30 July 1973 [31 July 1972 14 June 1973] 36145/73 Heading C1A A process for preparing alkali metal polyphosphates having a predetermined crystalline form comprises, in a first stage, joining a mixture of alkali metal orthophosphates into spherical granules in the presence of water, the granules obtained having a molar ratio of alkali metal oxide/P 2 O 5  of from 1 to 2, drying the spherical granules at a temperature less than 120 C. and, in a second stage, heating the granules to form polyphosphates. It is preferred to prepare the granules from a mixture of mono and disodium orthophosphates, having a molar ratio of Na 2 O/P 2 O 5  close to 5/3, using a 50% by wt. aqueous solution of these salts to give granules of an average grain size of 0À1-3À15 mm. which are dried at 100 C. in, for example, a fluidized bed. The second stage of the process in which polyphosphates are formed is carried out either by (a) heating the dried granules in a fluidized bed or (b) introducing the dried granules into a fluidized bed by means of a pneumatic conveyer at a high temperature, in the presence in both cases of water vapour. In the case of processes (a) the average residence time of the granules in the bed is 5-30 mins. At a temperature of 300-400 C. in the bed granules of phase II tripolyphosphates are attained, whilst at temperatures of at least 480 C. phase I tripolyphosphates are obtained. The use of intermediate temperatures allows the formation of both phases in a predetermined manner. In the case of process (b) the dried granules are introduced into a pneumatic conveyer at a high temperature, e.g. 550 C. to give a residence time of a few seconds in the conveyer and 1-10 mins. in the following fluidized bed. The ranges of temperature in which phase I and phase II are formed are less high than in process (a). The water vapour content of the bed gases is preferably 14-100% by weight.

Title: Improvements in or relating to electric pulse counting circuits
IPC: H04L5/24
Filed: 1956-11-28
Abstract: 816,487. Electronic counting apparatus. GENERAL ELECTRIC CO. Ltd., and SPEED, R. F. B. Nov. 27, 1957 [Nov. 28, 1956], No. 36441/56. Class 106 (1). An electric pulse counting circuit comprising a chain of counting stages each including gating means and delay-line storage, responds to an electric pulse signal carrying information in respect of a plurality of channels in timedivision multiplex. As described, input signals on a line 4 are time-divided into 100 channels, each channel being allocated one microsecond in each cycle of 100 Ás. duration. Each stage of the counter comprises a 100 Ás. magnetostrictive delay element 9, 10, 11 ... &c. and an inhibiting gate 15, 16, 17 ... &c. for erasing selected signals in the case of carry-over or zeroization. Thus, according to the timing of a 1 Ás. pulse on line 5 all signals relating to the selected channel may be deleted from the counter. Supposing now that a new count is starting in this channel, the first pulse passes an OR gate 12 and enters the delay loop, reappearing at the gate 12, and also an AND gate 1, 100 Ás. later in coincidence with the next pulse position allocated to this channel. If another significant pulse appears on the line 4 at this instant the gate 1 opens to allow entry of a pulse into the second stage of the counter including the delay element 10, and also provides an inhibiting signal, via an OR gate 18 to erase the first pulse at the gate 15. A third pulse in this channel is entered in the first storage stage without affecting the signal circulating in the second stage, but a fourth pulse is passed through to the third stage and erases the signals in the first and second stages. Thus the circuit operates as a binary cascade counter-registering the counts in a plurality of channels simultaneously. A more detailed description of one stage of the counter is also given with reference to Figs. 2, 3 and 4 (not shown) of the Provisional Specification.

Title: Improved means for regulating the heating effect in apparatus heated with steam
IPC: F24D1/00
Filed: 1928-12-11
Abstract: 302,903. Rosenblad, C. Dec. 22, 1927, [Convention date]. Heating systems and apparatus.-In steam heated apparatus e.g., boiling, evaporating, or drying apparatus, in which a number of units are connected in parallel between supply and return pipes, the excess steam being returned or otherwise used, the outlet from each apparatus to the return pipe is throttled to prevent any return flow of the condensate. A separator is provided in each outlet, and is connected to a common condensate main and a common steam outlet main. Steam passes through an injector 3 to a pipe 4 which supplies heaters 8 associated with boiling, evaporating, or drying apparatus. Steam separators 25 are provided in each outlet 9, and the steam and condensate outlets 26, 27 are throttled at 30, 31. Steam and condensate pass into common mains 33, 29 respectively, and thence to a receiver 13. In the event of the orifice 31 being blocked, condensate will pass with the steam into the receiver 13. The separated steam passes through a pipe 18 either to the injector 3 for return to the system, or to the pipe 19 for use in some other steam-consuming device. A valve 24 is 'provided to regulate the pressure difference between the pipe 4 and the receiver 13. The valve 24 may be automatically controlled by the pressures on the two sides, and a pressure gauge 21 may be provided. In the event of any abnormal reduction of pressure in the apparatus 7 the throttles prevent a large back flow of condensate. In a modification, the throttles 31 in the outlets from the condensate separators may be replaced by U-shaped water seals. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification Fig. 1 (cancelled) not shown, in which the heating devices discharge directly through a throttle into a common main leading to a common separator corresponding to the receiver 13. This subjectmatter does not appear in the Specification as accepted.
