Title: Sighting device for anti-aircraft guns
Filed: 1945-07-10
Abstract: 614,319. Sighting-apparatus. GATTIKER, W. July 10, 1945, No. 17634. [Class 92 (ii)] A sighting device for anti-aircraft guns comprises a laying telescope containing a parallellined graticule 14 and a tilting prism 16 operable by a manual control 1, the arrangement being such that the aircraft appears to move parallel to the lines while the mirror tilts to follow the aircraft according to its angular speed, the sighting device being provided also with calculating apparatus for determining the aimoff corrections arising from movements of the manual control means and from data set into it corresponding to the measured range. The mechanism shown not only sets in such data to the gun layers telescope and to the calculating mechanism, but also, by shafts 5, 90 and 110, to the graticule and prism of a telescope for the gunner. When the control 1 is rotated, it produces by shafts 3, 5, 7 and 9 and gears 10, 11, a rotation of the telescope housing 12, and by shaft 5 a similar rotation to the housing of the gunner's telescope. The lines of the graticule are thus moved in accordance with the path of the target. Translational movement of the control 1 moves, by a disc 20 on the shaft 18 of the control, a slide 21 which carries with it a slide 22 on a fixed rail 23. A rack 24 on slide 22 rotates a shaft 26 geared via shafts 28 and 30 to a shaft 32 whose cam disc 33 causes a displacement of a roller 35 over the disc 37, rotating at a constant speed. The resultant continuous rotation of the disc 35 is then communicated via differential 42 and gearing 48 to a ring 49 on the tube 12 which ring, by gearing 50, 52, serves to move the prism 16 so that it follows the target continuously. The differential 42 deducts the movement of the gun mounting, and a differential 45 adds to the rotation of the ring 49 the rotation of the tube 12. The translational movement of the control 1 is thus a measure of the angular speed of movement of the target and this is multiplied by the range, as set in by a handle 83, by a cam 82 to produce on a cam follower 80 a movement corresponding to this product. A device 95, 96 and lever 99 transmits such movement to the follower 103 of a further cam 102, so designed that the product is divided by the mean projectile velocity to give the aim-off angle as a movement of the follower. Such. movement is conveyed by a device 106, 107, rack 108 and gear 109 to the shaft 110 leading to the gunner's telescope. A lever 155 is moved one way or the other according to whether the target is approaching or receding to add a correcting movement to the range as set in by handle 83 to the common shaft 150 of cams 82 and 102, and the corrected range is fed by shaft 157 to the shaft 90 leading to the gunner's telescope. The three shafts leading to that telescope serve to move its prism and its graticule in accordance with the data given to produce between the gun and sight the correct aim-off angle.

Title: Apparatus for binding parcels
IPC: B65B13/02
Filed: 1951-07-25
Abstract: 707,418. Wire strainers. REBICHON, A. July 25, 1951 [July 28, 1950], No. 17638/51. Class 45. [Also in Group XV] A parcel binding device comprises a handle 3, Fig. 1, which controls the rotation of a free-wheel mechanism for driving a knurled roller 33 engaging and tensioning a binding tape and also controls the descent and the rise of a sealing block 10 carrying a stamping blade 11 for compressing a sealing sleeve round the tape. The sealing block 10 is detachably guided on the frame 1 of the device and is raised by a detachable connecting rod 15, Fig. 22, so that one sealing block may be replaced by another carrying a different size stamping blade 11. The frame 1 comprises a handle p, a foot portion 1a and a recessed portion 1b covered by a plate 2 in which are fitted the handle 3 and a second handle 4. Clockwise movement of the handle 4 lowers, by means of an eccentric mounting on an axle 6, the knurled roller 33 into contact with the upper tape and grips it against the lower tape held on the underside by an adjustable gripper 36. Also keyed to the axle 6 is a driven member 39 of the free-wheel mechanism driven by a gear wheel 38 free on the axle 6. The gear wheel 38, by virtue of an arcuately slotted journal in the plate 2, is always in contact with a gear 28 as the handle 4 is moved clockwise. The gear 28 is keyed to an axle 5 of the other handle 3, which when moved clockwise into vertical position will rotate the gear wheel 38 but spring pressed pins in the member 39 of the free wheel mechanism ride out of helical grooves in the wheel 38 and no rotation is given to the knurled roller 33. Return movement of the handle 3 drives the member 39 and roller 33 grips the upper tape and tensions it around the package. When the tape is. sufficiently tight the lever 3 is swung clockwise a greater amount, i.e. nearly 180 degrees whereupon a cam 5a eccentric with the axle 5 engages a replaceable friction plate 14 which drives the block 10 downwardly so that the sealing blade 11 and a cutting blade 12, attached by a common screw to the block, form the seal and cut off the surplus tape respectively. The block 10 is raised by the detachable connecting rod 15 fitted over a pin 17 on the block and a pin 16 on the cam 5a. The block 10 and the connecting rod 15 are slidingly accommodated in a casing 47 fitted on to the frame 1 by means of grooves and held in place by a sprung ball in the frame 1 engaging a detent in the casing 47. The blocks accommodate stamping blades and cutting blades of different widths, the casing 47 being slotted at 47a to allow for the added width of the blades. The upper strand of the tape extends above a counter blade 21 and an abutment 23 which prevents the blades 12 and 21 parting during the cutting operation and ensures the tape is cut off flush with the sealing sleeve.

Title: Device for controlling the unwinding and rewinding of a sound-recording tape
IPC: G11B23/04
Filed: 1965-04-27
Abstract: 1,109,124. Tape recorder. USINES GUSTAVE STAAR S.A. 27 April, 1965 [29 April, 1964], No. 17663/65. Heading G5R. Apparatus for withdrawing a record tape 7 from and returning it to a cassette 4 of the type described in Specification 1,070,727 for recording or play-back in which the reversal of the drive when the tape has been withdrawn from the cassette and the stopping of the drive when the tape has been returned is controlled by photo-electric means. Insertion of the cassette 4 into the apparatus moves an arm 45 clockwise about pivot 52 and this movement in turn moves an arm 43 to the left so that a soft iron portion 47 on one end of the arm is in a position to be acted on by relay 51 and a hooked portion on the other end of the arm rotates a double arm member 28 about pivot 27. A raised portion 32 on one arm 31 of the member rotates an arm 26 about pivot 27 so that a roller 20 on arm 21 is moved to a position in which it holds the tape 7 in contact with capstan 72. The other arm 29 of the member releases a spring look which holds the cassette in the operative position. Operation of the spring lock applies energy to a pulse generating circuit which via a first drive relay connects the motor drive to the capstan 72 in a direction which draws the tape from the cassette 4 into a storage cassette 11, energizes a lamp 19 which co-operates in the absence of a tape with photo-cell 17 and also connects recording or play-back head 15 to an amplifier. When the tape has been completely drawn from the cassette photo-cell 17 is energized by the lamp 19 and acts on the pulse generator circuit such that a second drive relay is energized to reverse the direction of motor drive, lamp 18 co-operating with photo-cell 16 is energized and recording or play-back head 14 is connected to the amplifier. When the tape has been returned to cassette 4 the photo-cell 16 is energized and the pulse circuit energizes a stop relay 51 which attracts one end of arm 43 whereby the hook on the other end of the arm disengages pin 40 and the control arms return to their initial position which movement unlocks the spring lock 60 and ejects the cassette from the apparatus.

Abstract: 967,983. Rotary piston internal combustion engines. DAIMLER-BENZ A.G. May 8, 1962 [May 25, 1961], No. 17681/62. Heading F1F. To obtain large theoretical compression ratios in a rotary piston Diesel engine of the kind having a triangular piston planetarily rotatable within a housing having a substantially elliptical inner profile, the piston has a mounting member eccentric in relation to the driven shaft and eccentric in relation to a second mounting member so that the piston turns in relation to both mounting members. As shown in Figs. 2 and 3, the piston 3 is mounted on an eccentric bush 9 which in turn is mounted on the eccentric 10 of the driven shaft 11. The absolute angular velocities of the piston, driven shaft and bush are preferably in the ratio 1:3:-3. To achieve this, the transmission comprises an annular gear wheel Z, secured to the housing wall 12 meshing with a gear wheel Z 2  secured to the bush 9 having half the number of teeth and an annular gear wheel Z 4  fixed to the piston 3 meshing with a gear wheel on the eccentric 10 with the wheel Z 4  having one and half times the number of teeth of the wheel Z 3 . In an alternative construction permitting a larger diameter journal on the shaft 11, the annular gear Z 1  is replaced by a guide path 13, Fig. 4, which co-operates with three rollers 14 mounted on the piston radially inwards of each piston flank. Annular gear wheels 15, 16 mounted at 17 one behind the other on the shaft 11, respectively mesh with a gear wheel 18 formed on the bush 9 and a planet wheel 19 fixed to the housing wall 1 and meshing with a sun wheel 20 fast on the shaft 11. To permit the provision of compact combustion chambers, troughs 8, Fig. 2, in the piston flanks may be made rectangular in cross-section with the fuel injected across the width of the trough in a broad cone or by three separate jets with the combustion air squeezed between the piston flank and the housing profile passing over the bottom of the trough. Alternatively the trough 8, Fig. 9a, may be made relatively deeper with the bottom contour 27, Fig. 9b, shaped so that vertical eddies 29 occur on the side walls. Other suggested cross-sectional shapes of the troughs are omega, trapezoidal or with the bottom semicircular and outwardly flared at the top.

[Class 58] Cereals, such as barley, oats, and the like, and seeds containing oil or fat, including soya beans and nuts, are, without previous cooking and crushing or maceration, caused to swell by means of moisture at a temperature not exceeding 75‹ C. and are thrust through the gap between heated revolving cylinders thus being dried and converted into flakes which may subsequently be ground. In the form shown the swollen grains are forced between the steam heated rollers 1 by a battery of rams 2. The flaked material is removed by knives 4. The soaking to produce the swelling is performed with pure water or, if removal of bitterness is required, with a weakly acid or alkaline solution which may be followed by neutralization. Salt solutions may also be used and during or after the swelling treatment soluble or emulsified nutrients or medicaments such as phosphoric acid, lime and iron compounds may be added. Soya beans or other seeds containing oil or fat may be soaked in a 1 per cent solution of hydrochloric acid at about 45‹ C. and then stirred about in the liquid at an increased temperature such as 65‹ C. the liquid then being neutralized and drained off. The oil may be expressed from the flaked material or removed by a solvent. The supply of steam and the peripheral velocity of the rollers may be varied to regulate the heat supplied to the flakes.

Title: Method of producing the antibiotic fumagillin
Filed: 1954-06-22
Abstract: Fumagillin is produced by aerobically fermenting an aqueous nutrient medium inoculated with a culture of a fumagillin-producing strain of Aspergillus fumigatus, particularly Aspergillus fumigatus NRRL 2436, adding to the said medium during the fermentation process and before the pH of the medium is appreciably in excess of pH 7.5, an amount of a carbohydrate which is readily oxidized under the fermentation conditions to produce an acid sufficient to maintain the pH of said medium below about pH 7.5 and thereafter recovering fumagillin from the fermentation medium.  Specified carbohydrates are glucose, dextrin, sucrose, maltose and fructose.  The carbohydrate may be added intermittently during the fermentation process.  The nutrient medium contains a source of carbon, a source of nitrogen and mineral salts.  The preferred medium contains glucose, corn steep liquor and calcium carbonate.  Specified nitrogen sources are turbay B.G., peptone, beef extract, yeast extract and sodium nitrate; mineral sources are magnesium sulphate, potassium dihydrogen phosphate, sodium chloride, ferrous sulphate, copper sulphate and potassium chloride.  Fumagillin is recovered by adjusting the pH of the clarified fermentation broth to pH 7.5 to 8.5, removing fat by means of hexane, adjusting pH to 3.0 and extracting with chloroform.  The residue after removal of the chloroform is treated with acetone and the fumagillin obtained recrystallized from aqueous methanol.
