Containers such as trays, crates, bottle racks and baskets, are stacked in columns A . . . E, Fig. 1, between walls MG, MD, one side of each container other than the lowest containers being supported on the next lowest container in the same column and the other side being supported, in the case of the containers in columns A . . . D, on the next lowest container in the column adjacent that side and, in the case of column E, on the wall MG, the containers being laterally interengaged and the arrangement being such that by raising any container in the columns A . . . D, other than the lowest, the next lowest container in the said adjacent column can be slid out of its column. The walls MG, MD are formed by units nested on in another, the units MD2 . . . MD4 in the wall MD being interengaged with the containers in the column D and being individually raisable to permit those containers to be slit out of their column. The containers and the units MD2 . . . MD4 may be raised by a lever O inserted therebelow, or by mechanical, hydraulic or pneumatic jacks. The containers shown in Fig. 1 are described in more detail with reference to Fig. 2 (not shown) and other forms of containers are described with reference to Figs. 3, 4, 5 (not shown).

Title: Image projection apparatus
IPC: H04N3/23
Filed: 1973-12-14
Abstract: 1455290 Cathode-ray tube displays; television SONY CORP 14 Dec 1973 [20 Dec 1972] 57999/73 Headings H4F and H4T The image on the screen of a cathode-ray display tube 3 Fig. 1, (e.g. of a television receiver 1) is projected, obliquely, via a mirror 5 and projection lens 6 on to a concave viewing screen 2 and to compensate for distortions in the image on screen 2 due to the obliquity of projection, the concavity of the screen and inherent pincushion distortion in the image on the tube screen the horizontal and vertical scanning waveforms are modified to produce a compensating predistortion of the raster. The obliquity of projection produces a trapezoid-shaped distortion as shown in Fig. 3 and this is corrected by predistorting the raster as shown in Fig. 5 whilst the concavity of the screen produces a fan-shaped distortion as shown in Fig. 4 which is corrected by predistorting the raster as shown in Fig. 6. A circuit for producing horizontal and vertical scanning waveforms giving rise to such predistortions and including means for compensating for inherent pincushion distortion is described with reference to Fig. 7 (not shown). Fig. 2 shows a perspective view of the system.

Title: Battery chargers
IPC: H02J7/14
Filed: 1971-12-20
Abstract: 1342819 Battery charging systems NIPPONDENSO CO Ltd 20 Dec 1971 [25 Dec 1970] 58963/71 Heading H2H A battery charging system comprises an A.C. generator 1, a rectifier 2 for converting the A.C. into D.C. for charging a battery 3 and a charging indicator lamp 12 connected in series with a transistor 7. With the generator inoperative, the transistor 7 becomes conductive when an ignition switch 13 is closed, thereby illuminating the lamp 12. When the generator is running, either the terminal 1a or 1b of the armature winding is negative so that current flows through either a diode 8 or 9 thereby switching off the transistor 7 and extinguishing the lamp. A capacitor 11 prevents the illumination of the lamp at the zero cross-overs of the generator output voltage. Reference has been directed by the Comptroller to Specifccations 1,209,103 and 1,184,832.

Title: On-off wheel for step-ladders
IPC: E06C1/397
Filed: 1978-06-13
Abstract: The invention provides a wheeled step unit in which at least one of wheels 14 can be raised to allow the leg 18 of the unit to engage the ground to resist transport of the step unit and can be lowered from a retracted position to a ground engaging position to permit unit transport. One of the steps 26 is pivotally mounted and cooperates with a wheel latch mechanism 32, 34 in such a way that the latch mechanism can lock the wheel in its ground engaging position unless downward pressure on the pivoted step (such as applied by a person stepping onto the step) will cause the step to pivot to release the wheel to permit it to return to its retracted position. <IMAGE>

Title: A device to give obstetric assistance to a cow at the birth of a calf
IPC: A61D1/08
Filed: 1978-10-16
Abstract: The invention concerns a device to give obstetric assistance to a cow at the birth of a calf. The device comprises a longitudinal frame member 10 having at one end an end frame 11 which is laid against the hocks of an animal about to give birth, and having at the other end a pair of independently rotatable reels 14 and 15 which are adapted to carry two lines (not shown) for attachment to the butt joints of a young animal to be born. Each reel has a respective ratchet mechanism comprising a clutch plate 16 or 17 secured to the reel and a bolt 22 spring biassed into contact with the face 20 of the clutch plate, the face 20 having a series of holes 21 which are successively engaged by the bolt 22 as the reels are rotated by handles 18 and 19 in a forward direction such as to draw the lines away from the end frame 11. The bolt 22 cooperates with the holes 21 to permit such forward rotation but acts to prevent reverse rotation upon release of the handles 18 and 19 by locking in one of the holes 21. The frame member 10 is hinged intermediate its ends at 25 for folding over upon itself for storage and transportation. Furthermore, the end frame 11 may be hinged at 41 and 42 to the frame member 10 so as to permit the angle of pulling the lines relative to the end frame 11 to be varied during the birth. The ratchet mechanisms can be rapidly rendered inoperative by retraction of the bolts 22 to allow free rotation of the reels in the reverse direction in an emergency. <IMAGE>

Patent GB-2020313-A (GB)
Title: Processing metal chlorides
IPC: C22B34/12
Filed: 1979-04-06
Abstract: Metal may be recovered from metal chlorides, for example a mixed metal chloride residue from the fluidised bed chlorination of a titaniferous ore in the presence of carbon to produce titanium tetrachloride by heating, in the presence of a scavenging agent, which may comprise a combination of titanium dioxide and carbon inherently present in a residue from the aforesaid fluidised bed chlorination process, to at least 1500 DEG C and preferably to a temperature at which iron present is liquid. If the temperature is maintained at below 2200 DEG C iron, vanadium and niobium may be recovered preferentially to certain lower value metals which remain in the form of chlorides giving the possibility for the recovery of a high value mixed metal product. Titanium trichloride may be formed and this may be chlorinated to titanium tetrachloride thereby increasing the efficiency of the original chlorination process.

Title: Taper rolling machine
IPC: B21H7/00
Filed: 1979-09-19
Abstract: A taper rolling machine, which is designed such that the stock may follow a constant pass line throughout the whole of the taper rolling operation, comprises a pair of idler rolls (7 & 8) and a carriage (2) for gripping the stock (12) and drawing it through the rolls in a multiplicity of passes whilst the roll gap is controlled to impart the taper, this roll gap being adjusted by movement of only one (8) of the idler rolls. The invention is manifested by the carriage (2) being pivotally mounted at 6 and resiliently supported at its forward end by a pneumatic, hydraulic or mechanical spring. This enables the carriage to move in such a fashion as to maintain the constant pass line. <IMAGE>

Title: Electrolytic recovery of dissolved silver
IPC: C25D21/12
Filed: 1979-09-20
Abstract: In a sheet processing apparatus for determining the size of a sheet having one of a plurality of determined sizes, the apparatus has a number of sensors less than the number of sheet widths, which sensors are arranged across the sheet location. From the length and width information determined by the sensors the size of the sheet can be identified using a catalogue of sheet sizes stored in a microprocessor memory. This information may then be used to control the electrolytic removal of silver from a fixer bath in the processing of X-Ray films in which the concentration of silver salts depends on the area of film which has been processed. Identification of the sheet sizes enables reliable estimation of the silver salts dissolved in the fixer from the films. This enables the duration of electrolysis to be controlled so as to maintain the concentration of silver salts in the fixer at a suitable low level.
