Title: Power transmission apparatus
Inventor: FOSTER KEITH
IPC: B06B1/18
Filed: 1965-05-14
Abstract: 1,134,561. Percussive tools. NATIONAL RESEARCH DEVELOPMENT CORP. 10 Aug., 1966 [14 May, 1965], No. 20561/65. Addition to 1,038,832. Heading B4C. [Also in Division F1 A piston 13<SP>1</SP> for subjecting a drill bit or hammer 53 to successive impacts is oscillated by pulsating fluid pressure (e.g. air or oil) acting in a chamber 52 on the end 12<SP>1</SP> thereof and the return strokes of the piston are effected by fluid trapped in a cylinder space 21a<SP>1</SP> and a surrounding reservoir 37<SP>1</SP> and thus compressed by the forward movement of the piston. The cylinder space 21a<SP>1</SP> communicates with the reservoir 37<SP>1</SP> through ports of decreasing area in the direction of forward movement of the piston, and the ports are arranged to be closed by the piston 13<SP>1</SP> near the end of its stroke so that further compression of the fluid takes place only in the small volume of the space 21a<SP>1</SP> thus substantially increasing the braking effect. In a modification, Fig. 4 (not shown) the cylinder space 21a<SP>1</SP> communicates with two or more axially spaced surrounding reservoirs each of which communicates therewith through separate ports closable by the piston. To enable the piston to be stopped without cutting off the pulsating fluid, a valve 23<SP>1</SP> is provided which when open enables the pulses to be applied to both the chambers 52, 21a<SP>1</SP>. In the event of an excessive pressure occurring in the chamber 52 a relief valve (not shown) opens to cause the opening of the valve 23<SP>1</SP>. The valve 23<SP>1</SP> may cause restricted communication between the chambers 21a<SP>1</SP>, 52, when in an intermediate position.

Title: Insecticidal compositions
Filed: 1947-07-31
Abstract: Insecticidal compositions comprise phenols having a long hydrocarbon side chain substituent of 5-26 carbon atoms on the nucleus of the phenol and the polymers and esters of these phenols in the form of emulsions and solutions.  The phenol may be used per se as a solvent for a rotenone and/or pyrethrin bearing material, either by direct solution thereof or by extracting a suitable source, e.g. powdered derris root, and filtering off the insoluble matter.  Such a solution may be admixed with a petroleum oil, e.g. kerosene, or alternatively the rotenone and/or pyrethrin may be extracted from suitable source material by a phenol-petroleum oil mixture.  The phenol per se, or solutions as above, may be emulsified in water with the aid of a soap such as sodium and potassium oleate or linoleate.  The phenols may be such as are naturally occurring in plants of the Anacardiacea family, e.g. cashew nut shell liquid, marking nut shell liquid, juice of Japanese lac plants; constituents thereof, e.g. anacardic acid, cardol, anacardol and urushiol; cardanol (see U.S.A. Specification 2,098,824); any of the above phenols which have been modified by hydrogenation to satisfy the unsaturated bond of the long hydrocarbon side-chain, e.g. hydrogenated cardanol; acid treated cashew nut shell liquid; slightly polymerized cashew nut shell liquid; and acetates of any of the above phenols.  Mixtures of two or more phenols may be used instead of one alone.  Specified rotenone-bearing materials are derris root extract, derris resinate, barbasio, cube, timbo and pure rotenone.  Suitable petroleum oils are kerosene, gasoline, fuel oil, petrolatum and regular spray oils.

A variable-ratio hydraulic transmission comprises two positive-displacement piston-type hydraulic units 16, 17 disposed coaxially with input and output elements 12, 14 in a housing 10 and mounted to rotate with one of the elements 14, a fixed-angle swash-plate 22 associated with one of the units and arranged to rotate with the other element 12, a stationary combined liquidtransfer and valve-plate member 18 between the hydraulic units, a rotatable valve-plate member 19 between the member 18 and the unit 16 arranged to rotate with the fixed-angle swash-plate, and a variable-angle swash-plate 37 associated with the other unit 17 for varying the rate of transfer and the direction of flow between the units. The input element may be either the element 12 or the element 14. As described, however, the element 12 is the input element which is connected to the fixed-angle swash-plate 22, rotatable in bearings 13 in the housing, and connected by a sleeve 21 and splines 20 to the valve plate 19 disposed between the member 18 and a cylinder block 28 of the unit 16 forming the pump for the transmission. The block 28 is splined at 23 to a sleeve 25 which is splined at 24 to a cylinder block 33 of the unit 17 forming the motor for the transmission and connected by a free-wheel device 15 to the output element 14. Each cylinder block is formed with ports 32, 38 cooperating with arcuate slots and passages in the member 19 and valve-plate 28 arid has seven pistons 29, 34 having pressure-pads 31, 36 engaging the swash-plates. The cylinder blocks are urged towards each other and the member 19 and valve-plate 19 by keys 42, 44 and a spring 40 on a tie-rod 41. The swash-plate 37 of the motor is adjustable about a pivot 66 by an actuator 70 having pistons 68, 69 in a cylinder 67 supplied with fluid pressure under the control of a governor responsive to the speed of the output shaft 14; the movement of the swashplate from its neutral position results in the output element rotating at a higher or lower speed than the input element 12. A gear-pump 60 driven by gearing 61 from the output element 14 supplies fluid through passages 59, 58 to the member 18 for charging the pump and motor, excess oil passing through passages 62, 63, 64 to a pressure-relief valve 65 and the housing which is thus maintained full of oil.

Title: Apparatus for generating beam positioning currents for cathode ray tubes
IPC: G09G1/04
Filed: 1957-07-02
Abstract: 853,126. Cathode-ray tube circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 2, 1957 [July 2, 1956], No. 20901/57. Class 40(7). In an arrangement for generating beam positioning currents for deflecting the beam of a cathode-ray tube to a co-ordinate position determined by the energization pattern (voltage levels) of a plurality of input lines 1, 2, 4, 8 Fig. 4, according to a predetermined digital code, the voltage levels on the latter lines are so chosen in relation to the grid voltage E2 of four switching valves V1a - V8a and the (constant) current passing levels of constant current devices V1 R1 - V8 R8 that, depending on the particular code input to the lines, current from B+ flows either via selected ones (or all) of the switching valves V1a - V8a and the X axis pushpull deflecting coils 18, 20 or, via a second set of switching valves V1b - V8b and the X axis pushpull deflecting coils 19, 21, the amount of current flow being determined by the particular constant current device(s) in operation. A. similar arrangement 22 is employed for producing beam positioning currents for the Y axis push-pull deflecting coils 14 - 17, the complete arrangement being as shown in Fig. 1. Fig. 2 shows the deflection yoke carrying the push-pull windings 14 - 21 which are connected as shown in Fig. 3. Instead of employing push-pull deflection the yoke may be made single ended by removing coils 15, 17, 19 and 21, the initial (undeflected) position then being arranged to be near the edge of the screen when there is no current in the yoke. Since a single ended yoke has only half the effective deflection sensitivity of a push-pull yoke the constant current devices must be arranged to pass double the amount of current required for push-pull operation when a single-ended yoke is employed. In a modification of the arrangement of Fig. 4 the grids of corresponding pairs of switching valves i.e. V1a, V1b - V8a, V8b are supplied from the "off" and "on" state outputs respectively of four trigger circuits each of which is controlled by a respective one of the lines 1, 2, 4, 8 (Fig. 5 not shown). In both embodiments (i.e. Figs. 4 and 5) additional digital input lines may be employed by the addition of one constant current device and one pair of switching valves for each additional digital input line. The invention may be employed for deflecting the beam of the cathode-ray tube on to a character matrix to indicate characters representative of the input data.

Abstract: 1,211,009. Coated base for diffusion analysis; diffusion analysis. F. R. ELEVITCH. 13 Sept., 1967 [13 Sept., 1966; 29 Aug., 1967], No. 21040/70. Addition to 1,211,008. Headings B1X and B2E. A method of testing by diffusion analysis comprises providing a base and a film on the base of uniform thickness not exceeding 1 mm. of permeable gel impregnated with a reagent which is stable in a dry environment and unstable in the presence of moisture, applying to the film a measured sample to be tested, the reagent and sample reacting to form a reaction product that can be measured quantitatively, causing the reagent sample to come together by diffusion and measuring the quantity of reaction product. The base may be in the form of a tape or rotatable disc and may be made of flexible plastics material. The permeable gel may be made from aqueous solutions of agar,  agarose, starch or acrylamide which is polymerised in situ and the layer of gel may have sample receiving wells. The gel and reagent may be mixed before application to the base. The product may be measured by fluorescence, by spectrophotometry or by measurement of radioactivity. A fixing step may be carried out prior to determining the quanity of unknown. The base and film may be moved continuously or step-wise during analysis. In the analysis of serum protein a film 75 of permeable gel impregnated with 8-anilino naphthalene-1-sulphonic acid is applied to a tape and moved beneath pipette 91 which applies a measured amount of serum protein. A fixing agent, e.g. a dilute aqueous solution of formaudehyde and perchloric acid, may be sprayed through nozzle 92 on to the area to which the unknown has been applied. The tape may then be passed to a fluorometer 93. which may have a readout to record the result on a tape and/or a screen. In immunological testing the gel may contain rabbit anti-human gamma globulin serum. Samples of serum under test and of a standard serum are placed in wells punched in the gel. Rings of reaction product around the wells are made visible by staining.

Title: World timepiece
IPC: G04B19/22
Filed: 1971-04-19
Abstract: 1313631 Watches DAINI SEIKOSHA KK 19 April 1971 [27 Feb 1970] 21157/71 Heading G3T A world timepiece has a twenty-four hour time indicating disc 22, a rim 25 surrounding the disc and having printed on it the names of localities 25a in different time zones, first means for moving the disc and rim together and second means for moving the disc independently of the rim. A conventional movement drives a cannon pinion 11, a minute wheel 12 and an hour wheel 13, and the pinion 11 rotates a driving disc 15 via an intermediate wheel 14 so that once an hour a finger 18 mounted on the disc 15 indexes a star wheel 21 integral with the time indicating disc 22. To move the rim 25 and disc 22 together the winding stem 36 is moved into a middle position so that a clutch wheel 39 is in position a, Fig. 1, whereupon a projection 39a contacts one of the twenty-four teeth 25b on the rim 25. Each clockwise turn of the stem 36 causes the rim 25 to be indexed one tooth space in a counterclockwise direction. This movement of the rim shifts an intermediate lever 27 which moves an arm 30a of a corrector 30 which rotates clockwise so that the corrector finger 33 indexes the star wheel 21, and hence the time indicating disc 22, in a counterclockwise direction. To move the disc 22 alone the winding stem 36 is moved to an inner position so that the clutch wheel is in position b. In this position depressing the stem 36 causes a setting lever 35, engaged with the stem, to rotate counterclockwise against a returning spring 37. The setting lever engages a further arm 30d of the corrector 30 which is rotated clockwise so that finger 33 indexes the star wheel 21 and disc 22. When the winding stem 36 is in an outer position the clutch wheel 39, which is located in position c, is engaged with the minute wheel 12. Rotation of the stem thus causes the minute hand, the hour hand and the time indicating disc 22 to be rotated. In the embodiments depicted in Figs. 5 and 6 (not shown) the time in a particular time zone is indicated through an aperture (40a) in a dial and by an arrow (41) on a transparent dial respectively.

[Also in Group XV] A machine for winding interleaved paper and metal foil into a condenser has an attachment for binding the roll with adhesive tape. Binding tape is drawn from a spool 16 over guiderollers 17, 18, to hang at 25. Solenoid 34 is energized to withdraw a perforated surface 39 and the pneumatic cylinder 37 is operated to lower the whole of apparatus 6 until the perforated plate 39 is opposite the depending tape 25. Solenoid 34 is then de-energized so that the perforated plate 39 moves into contact with the depending tape 25, and by suction through tube 41, the depending tape is caused to adhere to the perforated plate; simultaneously cutter 24 is operated to sever the depending tape. Solenoid 34 is then energized to withdraw the tape 25 and the air cylinder 37 is operated to elevate apparatus 6; in passing 32, solenoid 34 is de-energized to allow the tape to be wiped by a water or glue-damped brush 31, and the tape is then carried up until it contacts with the rolled paper and foil on the mandrel 1, 2 so that rotation of the mandrel removes the tape from plate 39 (the suction being cut off) and wraps it round the roll. A thermoplastic tape may be used, the brush 31 being omitted and the perforated plate having a heater.
