Title: Improvements in or relating to measuring devices for determining the mean angle of heel or the mean angle of trim, of a ship
Inventor: DOS HELMUTH
IPC: G06G7/70
Filed: 1957-09-17
Abstract: 826,804. Measuring trim of ships. SIEMENS & HALSKE A.G. Sept. 17, 1957, No. 29288/57. Class 40 (1). The mean angle of pitch or roll of a ship is determined by integrating for a fixed time period the instantaneous value of the angle with the aid of a differential gear having two input members driven respectively at speeds the difference between which is proportional to this value. At the end of the time period, the position of the output member is transferred to an indicator. Integrating angle values. When the apparatus is switched on, relay 37 pulls up followed by 36 which locks, energizes 34 and releases 37 which, after a short interval starts timing motor 30. The latter drives a wiper 231 which on moving off normal releases 34, 36 and energizes 33 to ensure the running of the motor until wiper 321 again reaches normal. Relapse of 37 also completes a driving circuit for motors 18, 19 via eddy current brake magnets 195, 185, which take the whole current of both motors, and the respective parts of a current divider defined by the position of an arm 13 the position of which is controlled by a gyro, pendulum or the like. If it is assumed that the motor speeds are proportional respectively to (w + x)<SP>2</SP>/4w<SP>2</SP> and (w - x)<SP>2</SP>/4w<SP>2</SP>, where w is half the total resistance of the current divider and x is the resistance between the centre and the arm 13, then the difference between the speeds, i.e. the speed of output shaft 21 of the differential gear, is proportional to the instantaneous value of the angle being measured. Shaft 21 drives through reduction gearing a shaft 23 carrying wiper arms 241, 251 co-operating respectively with fixed and rotatable gapped rings. At the end of the time period, the position of shaft 23 represents the mean value of the angle and relay 37 re-operates to stop the motors 18, 19. Transfer of shaft setting to indicator; initiating fresh cycle. With shaft 23 off normal, the operation of 37 energizes 41 in series with motor 281 which drives ring 254 in the appropriate direction to follow up the wiper 251. When the latter is again in the gap, pointer 291 registers the mean angle. Relay 41 which has been holding 37, falls back and on the subsequent relapse of 37 relay 39 or 40 operates to open the circuit of one of the motors. The other then drives shafts 21, 23 until the latter is in normal position whereupon the energized relay 39 or 40 falls back and 34 pulls up to start a new cycle. Modifications.-Motors 18, 19 may be A.C. driven and the current divider may be inductive or capacitive. Pointer 291 can be set by other means than the follow-up device shown.

Title: An improved process of making a self preserving acid milk product especially adaptedfor the lower animals, and the product thereby obtained
IPC: A23K10/28
Filed: 1925-11-24
Abstract: 269,610. Hunt, A. P. Nov. 24, 1925. Milk preparations.-A moist acid food, particularly useful for conditioning lower animals such as pigs and chickens, is made from buttermilk, skimmed milk or the like by developing lactic acid therein from the lactose of the milk, then subjecting the milk to such heat treatment and agitation as to precipitate the casein content in non-adherent particles, and finally evaporating to produce a highly acid sterilized product having not more than 35 per cent of solids. The milk, inoculated, if desired, with a special culture such as B. Bulgaricus, is initially heated to a temperature of 75‹ F. or slightly higher until a total acidity of between 0.78 and 1.5 per cent is developed. Then with active agitation the temperature is raised slowly to 125‹ F. and then more rapidly to 180-185‹ F. The final evaporation is effected by a long continued relatively low heat treatment in a condensing apparatus or vacuum pan, giving an increasing concentration of lactic acid which may ultimately be as much as 6 per cent of the product.

The fabric draw-off mechanism of a straightbar machine comprises two independently operable shafts one of which effects the. withdrawal of the welt bar and its hooks and the other the take up of the fabric through the welt rod. The shaft taking up the fabric through the welt rod is provided with a roller around which the straps, having welt rod engaging hooks thereon, are wound together with the fabric knitted. After the completion of each knitted article of fabric the rotation of the shaft having the roller is reversed to discharge the article wound on the roller into a receptacle. The shaft 5 controlling the movement of the welt hooks is adapted to be rotated in either direction to advance the hooks to the needles and then withdraw, them after they have engaged the initial course. Rotation of the shaft 5 in either direction is achieved by the provision of two adjacent ratchet wheels 13, 14 having oppositely directed teeth adapted to be engaged by pawls 23, 24 pivotally mounted on the end of a rockable arm 36. A cover 20 fits over the wheels 13, 14 and is provided with openings through which the pawls 23, 24 may project when the casing is rotated to bring a corresponding opening into alignment with one of the pawls. By rotating the casing through mechanism operated from the pattern drum either of the pawls is brought into operative engagement with its ratchet wheel to rotate the shaft in the desired direction. The arm 36 is rocked by means of linkage operated by cams rotated from the main cam shaft. Stop pawls 85 ... 88 are also provided to engage the ratchet wheels 13, 14 and corresponding openings are provided in the casing 20 to enable them to be rendered operative or inoperative. The shaft 11 controlling the take-up of the welt rods is similarly operated by pawls 51, 52 acting through openings in a casing 48 on the ratchet wheels 41, 42, the pawls being mounted on a rockable arm 68. Stop pawls 89 ... 92 are also provided. By this mechanism the welt hooks are advanced and retracted to and from the needles for withdrawal of the initial courses of a welt of a stocking after which the welt rods are inserted and the fabric take-up is completed, the stocking being completely wound upon the take-up roller driven by the shaft 11 and then discharged into a receptacle by reversing the direction of rotation of the shaft 11 to unwind the stocking from the roller.
