Filed: 1924-09-22
Abstract: 232,160. Corn Products Refining Co., (Assignees of Newkirk, W. B.). April 11, 1924, [Convention date]. Drawings to Specification. Crystallizing.-In producing crystallized glucose from starch conversion liquors the crystallization is started by the addition of a considerable quantity of crystals of the type desired in the form of " foots " or crystallized liquor from a previous operation. The mixtures mav consist of about 40 per cent of " foots " and 60 per cent of fresh liquor, and if the liquid is very pure and a longer time is available the production of foots may be reduced somewhat. It is stated that in this way the operation can be carried on through a much greater range of temperature than is possible with a smaller amount of seed crystals. The liquor after concentration is cooled to a suitable temperature and then mixed with the " foots " in a vessel separate from the cooler. In preparing hydrated crystals the crystallization can begin at 105‹ F. and the temperature be gradually reduced to 80‹ F.; for anhydrous crystals the initial temperature may be 130-145‹ F. and the final 100- 120‹ F. Specification 227,140 is referred to.

Filed: 1974-05-21
Abstract: 1468909 Hardening steel pipe SUMITOMO METAL INDUSTRIES Ltd 21 May 1974 [21 May 1973] 22599/74 Heading C7N  A heated pipe is advanced past a quench unit which causes jets to impinge on both the internal and external surfaces at an angle of 20 to 40 degrees to the longitudinal axis of the pipe in the advancing direction, the intensity of quenching received by the inner surface decreasing progressively as the pipe advances past the unit. The latter feature may be achieved by providing a greater density of jet orifices at the leading end of the quench unit, while the first internal impingement of the jets may be displaced 20-150 mm. downstream from the location of external impingement. Quenching of the external surface may be commenced when the steel temperature is above Ac 3  and of the internal surface when the latter is just below A 1 . As illustrated quenching is carried out by an external head 1 including external orifices 4 and an internal unit 2 having orifices 6 and a conical cap 5 to prevent flow of water into the unquenched region of the pipe. The internal unit is mounted on the end of a boom 7 which is initially supported by jaws 20 until it enters the pipe, when it is located by rollers 27.

Title: Improvements in or relating to gyro compasses
IPC: G01C19/38
Filed: 1920-07-31
Abstract: 170,947. Brown, S. G. July 31, 1920. Gyroscopic compasses are corrected for errors due to changes of temperature by applying a torque which varies with the temperature and balances the error-producing torque, the invention being particularly applicable to compasses such as described in Specification 126,451 in which the gyroscope is in substantially neutral equilibrium. As shown in Fig. 1, a bracket e on the gyro-casing A carries an arm c to which is secured a bimetallic strip C extending horizontally across the casing and carrying at its outer end a weight D, adjustably mounted on a stud c'. The strip C bends with variation of temperature and causes the weight D to exert a varying torque around the horizontal axis of suspension x-x. this torque being adjusted to compensate for the error-producing torque due to changes of temperature. Alternatively, the balancing-weight may be wholly or partially replaced by electromagnetic means exerting a torque which is made to vary with the temperature, as by including in the circuit a wire resistance mounted on or near the casing.

Filed: 1923-09-12
Abstract: 224,333. Burrow, A. E., and Prahm, A. G. L. Sept. 12, 1923. Arresting a moving model by competitive control, apparatus for. - A game apparatus comprises a figure or object adapted to rotate above the surface of a table, a series of movable stops distributed round the edge of the table the movement, of each of which may be controlled by a number of competitive players so as to bring any stop into a position to engage and stop the rotating figure, an article or prize mounted on or supported by the figure and means for releasing the article or prize when the figure has been arrested by one of the players successfully bringing his stop into the correct position. A figure 10, such as a model lobster or airship is pivoted around a central pole 4 above a table 1 and is rotated by means of a fan driven by a electric motor 11. The claws 13 of the lobster hold a smaller lobster 14 or other article which is released as described below when a solenoid 16 is energized. Around the edge of the table 1 are a number of pivotal arms 30 each carrying an armature 32 and a receptacle 35, The players, by operating electric switches (not shown), cause the arms 30 to oscillate across the path of a slidable magnet 20 mounted on the lobster. If a player succeeds in bringing the armature 32 directly beneath the magnet 20 as it is passing, the attraction of the magnet causes the magnet and the armature to engage and arrest the rotation of the lobster. In this position, a brush mounted within the lobster rests on a stationary electric contact and a current is maintained through an electrothermostatic switch 62. The maintenance of the current causes the thermostatic switch to close the circuit of the solenoid 16 which thereupon raises the movable jaws 15 of the claws 13 and allows the small lobster 14 to be deposited in the receptacle 35. Alternatively, the small lobster may be lowered by a string. The arms 30 may be oscillated by mechanical instead of electrical means, and in a further modification each arm carries an electric motor provided with a fan which drives the arm in one direction when its switch is closed, the return movement being effected by a spring when the switch is opened. Specification 226,734 is referred to.

Abstract: 1,102,824. Controlling reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 23 May, 1966 [13 July, 1965], No. 22907/66. Heading G6C. The initial starting control of a nuclear reactor is effected through adjustment of control rods by a signal corresponding to the neutron flux level. The control circuit adjusts the reactivity so as to cause the flux to attain a given level within a specified time interval Ti. Logarithmic and differentiating circuits operate on the equation # p  = # i # t/# to derive the expression where # p  = required final flux density # i = existing flux density T i  = time required to attain the required flux # p  # = reactor period A further comparison is made between T i  and a required time T p  to provide an error control signal for the rods. The computed T i  is read directly by a meter. The arrangement may be modified to effect rapid shut down when T i  is less than a specified safe value.
