Title: Combination lock
IPC: E05B37/02
Filed: 1975-07-31
Abstract: 1510325 Combination locks WALTER KIDDE & CO INC 31 July 1975 [5 Nov 1974] 32085/75 Heading E2A A combination lock for a briefcase comprises: dials F each keyed to a sleeve G having a flange 14 with a flat portion 16; a plug having slots 38 engageable by the flanges 14 and receiving the dials F; and a bolt J engageable with the plug H. When the dials are off combination, Fig. 3, the flanges 14 are received in slots 38 in the plug which prevents linear movement of the plug, and the plug H, in turn, prevents the bolt from moving by bearing on upstanding wall 76. When the dials are on combination the flats 16 of the dials F lie adjacent the slots 38 but do not engage them, thereby allowing the plug H and the bolt J to slide, the bolt being moved by a spring-biassed pushbutton R so that a hook 72 of the bolt disengages from a keeper 3, Fig. 2. The bolt is reengaged by using a spring-biassed push button L. A cam 62 engages the top of an upstanding wall 86 of the bolt during its to and fro motion by the spring-biassed pushbuttons, to bias the bolt to either end of its travel. Marks 102 on the flats 16 of the dials are visible through inspection holes 108 in the lock casing. A spring bearing on the circumference of each dial (Fig. 5, not shown) releasably maintains the dial any selected combination. The combination may be changed by moving a shift lever Q towards and against the bias of a spring P, thereby moving the sleeve G out of keyed engagement with the dials which may then be rotated to a different position.

Title: Radiation sources and methods of and apparatus for manufacturing them
IPC: H01J9/34
Filed: 1977-08-01
Abstract: 1530254 Radiation sources ORIGINAL HANAU QUARZLAMPEN GmbH 1 Aug 1977 [4 Aug 1976] 32270/77 Heading H1F Insulating caps 24 are applied to the constrictions 16 at either end of a radiation source 10, e.g. an infra-red lamp, by pressing the constrictions into the caps while these are in a plastically deformable state to an extent dictated by the spacing of intended mountings for the source, free space being retained within the caps for the connecting wires 20 and the exterior of the caps remaining unaltered. The caps are preferably of plastics material and are mounted in arecess in a metal plate heated to about the softening point of the plastics, while the source, held vertically in an adjustable clamping means, is heated at a constriction to the melting point of the plastics and pressed in to the desired extent.
Patent GB-803722-A (GB)
Title: Vertical velocity meter
IPC: G01P3/62
Filed: 1956-10-23
Abstract: 803,722. Measuring rate of climb. SPERRY RAND CORPORATION. Oct. 23, 1956 [Oct. 27, 1955], No. 32324/56. Class 40 (1). In a rate-of-climb indicator operated by integration of vertical acceleration cumulative errors are cancelled out by a signal derived from comparing the integrated accelerometer output with the differentiated output of an altimeter. In Fig. 1, a gyroscope rotor turns about an axis XX in a drum 8 which is eccentrically mounted on axis YY, the drum being balanced by weight 9 and spring 15 to be level when acted upon by gravity alone. Vertical acceleration (positive or negative) causes the drum to tilt about YY and this in turn induces precession of the frame 2 about the vertical axis ZZ. The tilt is detected by brushes 19 bearing on a contact segment 14, and these energize the winding 24 (Fig. 2) of motor 16 which rotates ring 4 in one direction or the other to oppose the precession and maintain the drum level. Stabilization of the whole apparatus is effected by gyroscope repeaters 21, 21<SP>1</SP> acting about the axes X<SP>1</SP>X<SP>1</SP> and Y<SP>1</SP>Y<SP>1</SP> respectively. The slider of potentiometer 28 is thus turned through an amount dependent on the velocity of climb and a signal output 34 (Fig. 2) is obtained from the transformer 92. The barometric altimeter 38 similarly produces an output from the E-type pick-up 32 which is amplified and differentiated in the motorgenerator unit 42, 46. Intermittent response of the altimeter is smoothed out by mechanical feedback through 44 and electrical feedback via 51. The integrated accelerometer output 34 is similarly smoothed in the unit 60 which comprises an amplifier feeding a motor controlling the slider of a mains-energized potentiometer 54. The signal from this is combined with a fraction of the output 34 and applied at 50 to a circuit 76 which is also supplied with the differentiated altimeter output at 48. The difference between the two signals is amplified and passed via 62 to the motor 18 which (Fig. 1) rotates the tilt axis of the drum 8 by an amount which compensates for the cumulative errors. A radio altimeter may be used instead of a barometric altimeter. The errors may be further reduced by introducing into the accelerometer output 34 a portion of the error signal applied to motor 18.

Title: Improvements in trawling nets
IPC: A01K73/02
Filed: 1923-12-28
Abstract: 235,923. Rowton, H. S. Dec. 28, 1923. Nets.-An otter trawl or the like fishing net is constructed so that the length and form of the head rope BD, foot rope BE, and selvage ropes BF while the net is under construction correspond to those of the curves of free suspension of a rope or the like suspended. from two points equivalent to the spread of the net and passing through points D, E, F at given distances from the line BC joining the wings. Fig. 1 shows diagrammatically half the spread BC of the net and half of each curve. There may be one or two selvage ropes. The upper surface of the net between the selvage rope and the head rope is increased slightly in a transverse direction throughout the wings of the net to allow the top of the net to rise freely when lifted by floats, kites, or the like. The selvage ropes may be continued into the cod end, where they join as one rope at the purse portion so that the weight of the cod end is taken by the selvage ropes and does not hang on the head rope. The selvage ropes may be connected across by short spliced ropes at the cod end. The net adjacent the ropes also conforms to catenary curves, and for this purpose, when a change in size of mesh occurs, the number of the smaller mesh is increased so that the width at the point of change remains constant.

Title: Improvements in and relating to package advancing mechanism for wrapping machines
IPC: B65B35/24
Filed: 1934-11-12
Abstract: 432,247. Endless - chain conveyers. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Nov. 12, 1934, No. 32557. Convention date, May 2. [Class 78 (i)] [See also Group XVII] Means are provided for ejecting all the packages from the drying or sealing chamber of a wrapping-machine, at the end of a series of packages, or otherwise when no packages remain to push out those in front of it. The packages P are pushed by arms 5 over a table 14 between end sealing or drying plates, not shown, until, in the normal operation of the machine, a row of packages extends to a delivery belt 49, which row is pushed forward by each succeeding package. The arms 5 are pivoted at 6 in lugs 7 on chains 8 and are held in the operative position by the action of a rail 18 on rollers 17 mounted on arms 16 on the shaft 6. After the rear package has been advanced to a predetermined position, the rollers 17 travel up a curved edge 20 and allow the arm 5 to swing backwards and disengage the package. Each package passes over a spring plate 24 and depresses it to the level shown in full lines. This, through levers 25, 31, raises a link 32 and a lever 33 and swings a rail member 43 about its pivots 40 into an inoperative position. In the absence of a packet, the plate rises to the position 24<1> shown in broken lines and allows the link 32 to fall, whereupon the rail 43 swings into an operative position. The roller 17 is thus engaged by the rail and is prevented from riding up the slope 20, so that the arm 5 remains in the engaging position until it reaches the left-hand position shown in Fig. 2. The table 14 is thus cleared of any remaining packages. The rail is released for movement into its operative position by the approach of an arm 5, the roller 17 acting on a pin 46 to elevate a spring 47 carrying a stop 48.

Title: Improvements in or relating to charging apparatus for furnaces, kilns and the like
IPC: F27B1/20
Filed: 1919-12-29
Abstract: 137,297. Candlot, C. July 10, 1917, [Convention date]. Charging.-A continuously rotating table 2 is fed from a shoot 3, and the material is swept by a scraper blade 20 into a shoot 21, which is carried round the furnace by intermittent movements. The table 2, which surrounds the central chimney 1, is mounted on ball bearings, and is driven from a motor through gearing 9, 7, 6. The shoot 21 and scraper blade 20 are fixed to a lower plate 12, which is normally held stationary by a pivoted catch 17 in engagement with abutments 18 on the furnace top, but is frictionally driven from the table 2 when the catch is tripped once in each revolution of the table by a cam surface 15. When the scraper blade moves from behind to a position in front of the delivery point of the shoot 3, a double amount of material will be supplied to the furnace, since the table is already covered, and the supply through the shoot 3 is continuous. To compensate for this, the catch 17 is tripped twice during this particular revolution of the table, the first time by a lever on the table 2 actuated from a cam surface on the furnace top through an intermediate lever on the plate 12, and the second time by the cam 15. The delivery portion 22 of the shoot 21 can be rotated about a vertical axis by a hand-lever to distribute the material over the whole area of the furnace.

Title: Journal and bearing assemblies
Inventor: BETTS COLIN
IPC: F16C33/00
Filed: 1962-08-28
Abstract: 979,731. Bearings. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 27, 1963 [Aug. 28, 1962], No. 32938/62. Heading F2A. [Also in Division B5] A method of maufacturing one member of a fluid bearing comprises casting resin between a mould having a high quality finish which is pre-treated to prevent adhesion of the resin thereto and a backing piece having a keying surface thereon for the resin. The resin may be epoxy-based and may contain, as an additive, 20% by weight of MoS 2 . The backing may be metal. In an embodiment, a moulding-shaft 3 is located by a recess 2 in a brass body 1 and a backing-piece 5 is located by a recess 4 which is in the body 1, is concentric with the recess 2 and has a reduced depth. The body has a removable top plate 6 supporting a filling- tube 7 which communicates via passages 8, 9 in the plate 6 and body 1, with an annular space 10 between the shaft 3 and coaxial sleeve 5. The latter is in its rough-machined state and is degreased and the shaft 3 is coated with release wax. Mixed portions of the resin are transferred from a mixing vessel (not shown) by means of slight backing pressure being applied to the surface of the liquid resin, thereby forcing it through the tube 7 and into the annular space 10 where it is allowed to set. When thin resin linings are required, the apparatus as shown in Fig. 1 is contained in a sealed vessel having a vacuum connection so that the resin is de-gassed before and after mixing. The mixed resin is drawn into the annular space 10 by evacuating the sealed vessel through the connection. The methods described are particularly advantageous for manufacturing members having bearing surfaces which are of a shape, such as elliptical for example, that is difficult to obtain by machining.

Title: Method and apparatus for growing quartz crystals
IPC: C30B7/00
Filed: 1949-12-29
Abstract: <PICT:0680773/III/1> Quartz is grown by supporting one or more quartz seeds in a container above a nutrient mass of quartz particles, the seeds and nutrient being in contact with a single - phase aqueous medium containing sodium ions and having a specific volume not greater than approximately 1.67 times that of the aqueous medium at normal temperature, the temperature in all parts of the container being at least 375 DEG C, in the region of the nutrient at least 380 DEG C and in the region of the seeds a few degrees, preferably not more than 5 DEG C, higher than the temperature in the region of the nutrient.  The sodium ions may be derived from sodium hydroxide, carbonate, silicate or other sodium salts, particularly salts of weak acids, and the aqueous medium may contain a small concentration, e.g. 0.001-0.005 normal, of e.g. sodium oleate. The sodium-ion concentration is preferably at least 1/2 normal.  Suitable apparatus comprises an expendable container 1 fitting closely into the bore of a heavy cylinder 14 closed by end caps 15, 16.  Intermediate caps 17, 18 fit into the ends of the container 1 and the cap 18 is bored at 19 to provide a safety vent should the container 1 rupture.  Quartz particles (size about 1/2 -inch diameter) are placed in the container 1 together with one or more quartz seeds supported by a stirrup 10. The seeds may have their faces perpendicular to the crystal axis or parallel to a major rhombohedral face.  The crystal axis may be parallel to or at an angle to the axis of the container, at least 60 per cent and preferably 80 or 90 per cent of the remaining free space in the container is then filled with the aqueous medium and the container sealed and inserted in the cylinder 14 which is then stood on a hot plate in an insulated container (see Group XI).  The insulation is arranged to allow heat to be dissipated from the upper part of the cylinder 14 to give the required temperature gradient. The temperature in the hottest part of the container should not exceed 550 DEG C and the temperature difference between seeds and nutrient should preferably be not more than 5 DEG C, estimated by external measurements at levels A and B, to avoid spurious seeding. Growth rates of 0.09 and 0.04 inches per day are referred to in examples.
