Filed: 1970-05-04
Abstract: 1295830 Mandrel R WARSAGER 4 May 1970 [27 March 1970] 21445/70 Heading B6G A mandrel on a machine for applying decorative material to a hollow object by hot stamping comprises, as shown in Fig. 3, a shaft 37 having an offset portion 38 and rigidly secured to the machine at the end opposite the offset portion, a leg 39 pivotally secured to the offset portion such that the leg can be pivoted to be in axial aligment with the offset portion so that the hollow object can be readily placed over the leg and offset portion. An abutment 41 on the offset portion 38 limits movement of tab 42 fixed to leg 39 thereby preventing downward movement of the mandrel past a position at approximately 90 to the offset portion 38. A roller 43 may be freely rotably journalled on the leg 39. If desired the tab 42 can be eliminated and the roller can extend such that it will abut against the offset portion when the leg is it an angle of 90 with respect to the offset portion. In operation, a bottle is placed over the roller, the bottle is then lifted upwardly whereupon it lifts the leg 39 upwardly until the leg is in axial alignement with the offset portion 38. The bottle is then pushed over the offset portion until the edge of the mouth of the bottle engages the shaft 37. The bottle is then lowered and can be further pushed over the shaft 37 when the bottle reaches its full downward position. As the object is pressed against the die of the hot stamping machine the roller on the leg 39 engages the inner surface of the bottle and prevents it from collapsing. The bottle is free to rotate on the roller.

Title: Measurement of surface configuration
IPC: G03H1/00
Filed: 1971-04-19
Abstract: 1328808 Holography UNITED KINGDOM ATOMIC ENERGY AUTHORITY 19 April 1971 [3 Feb 1970] 5226/70 Heading G2J In a method of measuring surface configuration, e.g. the determination of co-ordinates of points on a three dimensional surface, a hologram 22 of a reference pattern is located at a distance from an object surface 32 and is illuminated by at least two reconstructing beams 29, 30 at spaced locations to form real images of said pattern on said  surface, and the points on said surface where the images coincide are observed. In making the hologram only a single reference beam is used. In the reconstruction the beams 29, 30 are directed through the hologram from the side opposite that exposed to the reference beam. The reference pattern may be a rectangular or circular coordinate graticule whereby the points of coincidence of the images are the cross-over points on the reconstructed graticule images. The beams 29, 30 may lie in a plane parallel to either set of lines or in a plane parallel to neither set of lines. To determine points lying in a series of parallel common planes the distance between hologram and surface may be changed by known displacements; or the hologram may be a multiplex construction formed by successive exposures with the hologram/pattern distance different for each exposure. It is desirable that the beams 29, 30 be of sufficient diameter to give a depth of focus lens than the separation of two planes to be measured. In an alternative a hologram may be divided into portions which are successively displaced from each other 22/1-22/3, Fig. 7, in directions normal to and parallel to the plane of the hologram. Two reconstructing beams are redirected through each hologram either in turn or simultaneously. If desired, the reconstructing beams can be directed through the hologram alternately at a rate which facilitates optical observation of coincidence points, e. g. using a rotary shutter 35, Fig. 5. Where the circular co-ordinate graticule is used at least three reconstructing beams are needed. The co-ordinate lines need not be continuous but may be dotted, dashed or otherwise coded. The hologram may be formed using evanescent waves.

Abstract: 1332321 Hose reeling apparatus DASIC EQUIPMENT Ltd 23 Dec 1970 [15 April 1970] 18023/70 Heading B8M A hose reeling machine comprises a connection 11 for pressure fluid, a rotatable drum 8 for reeling flexible hose through which the pressure fluid supplied to the connection 11 can pass, a wheeled trolley on which the drum is rotatably mounted, drive means to rotate the drum, the drive means being drivable by pressure fluid supplied to the connection 11, and means whereby the wheeled trolley can be locked in position relative to an aperture in the upper wall of a tank through which aperture the hose can pass to a tank washing machine positioned to wash the inner walls of the tank. Means may be provided to control the drive means such that upon initial energization of the means, the drive means rotate the drum to reel-out hose while supplying fluid thereto, until a predetermined length of hose has been reeled out, and then upon operation of limit means, rotate the drum to reel-in the hose until further limit means de-energize the drive means. In operation, the drive means comprises a Pelton wheel connected by gears to a trunnion 10 on which the drum is mounted. In one embodiment, pressure fluid is supplied to the connection 11 and a duplex valve 18 supplies fluid to either feed line 19 or 20 to supply fluid via nozzles to the twin Pelton wheels provided in housing 14. The output of the Pelton wheel is transmitted via gearing at a reduction of preferably 500 : 1 to rotate the drum 8 to reel out hose. After sufficient hose is reeled out, the stop valve 12 is opened to feed pressure fluid via pipe 13 to a hollow trunnion 9 of the drum and thence via an axial connection to the hose on the drum. After a predetermined length of time, the valve 18 is actuated to supply pressure fluid to the other feed line 20, 19 to reverse the rotation of the shaft of the Pelton wheels and thus reel-in the hose, the stop valve 12 having been closed. In an alternative embodiment, the reversing of rotation of the shaft of the Pelton wheels is actuated automatically. Rotation of the drum 8 causes a lead screw or a pinnion driven rack to be operated, which screw or rack carries abutment means co-operating with a projection on a rotatable member driven for rotation through a limited arc of movement by abutment of the projection and the abutment means. The rotatable member is so connected to valves that in one extreme position of its arc of movement, the drum rotates in one direction, in a middle position rotation of the drum is prevented, and in the other extreme position, the drum rotates in the opposite direction. The drum is mounted on a trolley comprising a frame 2, 3, 4, 5 and wheels 7 and is associated with a machine for washing the inside of a tank for example on a tanker ship. The trolley carries a cover 27 with a hose guide 29 for positioning over an aperture in the top wall of the tank. A further hose guide 30 may be provided on the trolley and a pinion 17 may be provided to which a handle can be attached for emergency reeling of the drum.

Abstract: 1336255 Radar SHORROCK DEVELOPMENTS Ltd 14 March 1972 [19 March 1971] 7357/71 Heading H4D [Also in Division G4] In an intruder alarm a micro-wave field is provided in a protected area PA by at least one transmitter T1, signals reflected from objects in the protected area being picked up by two receivers R1, R2 each producing a Doppler signal, a comparator C being included to provide an alarm-initiating output when the Doppler signals from the two receivers R1, R2 are substantially alike. As shown, two transmitters T1, T2 operate at 10,000 MHz and prevent false alarms due to transmitter noise. The receivers R1, R2 are synchronized by a reference signal from the respective transmitter. The comparator may be responsive to Doppler frequency, phase or amplitude, and may feed an AND gate D1, D2, D3 which only provides an output to the alarm B in the presence of Doppler signals from both receivers and a similarity signal from the comparator. The use of two receivers prevents false alarms due to movement of small objects. The two transmitters T1, T2 may operate on the same or slightly differing frequencies. In Fig. 1 (not shown) only one transmitter is employed and the AND gate is omitted.
