Title: Improvements in process and apparatus for continuous casting of metal ingots
IPC: B22D11/14
Filed: 1966-08-04
Abstract: 1,093,409. Continuous casting machines. ALUMINUM CO. OF AMERICA. Aug. 4, 1966 [Aug. 16, 1965], No. 35078/66. Heading B3F. [Also in Division F4] In an apparatus for continuously casting simultaneously a plurality of ingots from horizontally disposed open - ended water chilled moulds 14 means are provided, in the event of defects in one of the ingots, for closing off one of the moulds 14 and restarting casting from it without affecting the casting operations in the other moulds 14. The apparatus comprises a main feed 60 of molten metal feeding the moulds 14 through a distribution header 62 and branch troughs 64. The ingots emerge from the moulds 14 in a common horizontal plane and parallel to each other and a continuous belt 40 supports and withdraws the ingots under hold down rollers 46 to a shearing station at some location from the end of the belt 40. To close off a mould 14 a tapered plug 76 stops the flow of molten metal into the branch trough 64 and removal of plug 67 drains out the said trough. To re-start casting from the mould 14 a starting plug 84 is supported with one end in the mould 14 by a pair of rails 87 and, on restarting, a variable speed electric or hydraulic motor 166 withdraws the starting plug 84 by means of a cable or chain 170. The speed of withdrawal is gradually increased so that by the time the starting plug reaches the hold down rollers 46 it is travelling at the same speed as the belt 40. The starting plug 84 includes pins 118 and a rear guide assembly 120 for guiding the plug on the rails 87 and the rear guide assembly includes spring-loaded friction pads bearing on the rails 87 to prevent the plug 84 moving prematurely by contact with the belt 40.

Title: Automatic temperature control system
IPC: G05D23/24
Filed: 1958-11-03
Abstract: 871,976. Automatic temperature-control systems. STEVENS MANUFACTURING CO. Inc. Nov. 3, 1958 [Nov. 1, 1957], No. 35197/58. Class 38 (4). [Also in Group XXXVII] In an automatic temperature control system for a vessel heated by a heating unit first, and a second relatively movable operating portions connecting the heating unit to a source of heat energy, are varied relatively in response to the temperature of the vessel so as to reduce heat input with rise in temperature and in response to the heat energy supplied to the heating unit so as to tend to reduce the heat energy input. As shown, a cap 16 is depressed against the action of a spring 17 by a vessel 18 being heated by an element 12. The cap 16 contains a sensing coil 21 having a resistance dependent on the temperature of the vessel 18. The A.C. supply from lines 41, 42 to the element 12 is through a cam-operated switch 44, a fixed contact 31, a moving contact 30 and a portion 37 of a U-shaped bimetal assembly 29. A heating coil 64 in parallel with the sensing coil 21 and a heating coil 66 in parallel with a resistor 65 are connected in series across a low-voltage secondary 58 of a transformer 55. Reduction in current through the coil 64, due to an increase in temperature of the vessel 18, causes a deflection of a portion 38 of the assembly 29 tending to reduce the " on " time of contacts 30, 31 and the coil 66 causes a deflection of portion 35 tending to compensate for change in ambient temperature. The supply current through portion 37 causes a deflection tending to compensate for change in the supply voltage and during boiling regulates the mean current through the element. In a modification, a series lamp replaces transformer 55 to reduce the voltage applied to the sensing coil. In a further modification, the sensing coil is replaced by a non-linear silicon carbide resistor.

Filed: 1928-12-03
Abstract: 301,911. Alaskas Corporation, (Assignees of Wolff, M.). Dec. 9, 1927, [Convention date]. Ice-creams and like preparations; coating confectioners' goods; confectionery.- A machine is arranged to carry confections, e.g. ice-cream blocks, each of which is impaled on a stick, in succession through a bath of coating material, e.g. chocolate, and under a device which deposits " confectioners' sprills " e.g. shredded chocolate, the carriers for the confections being swung, -firstly one way to present one side of the chocolate coated confection to the descending " sprills," and then the other way to present the reverse side. As shown, the carriers each consist of a frame 28, Fig. 6, attached by the link pivots to the endless chain 23 which is trained around sprockets 13, 19 - - 22 and is prevented from sagging by rails 24, a stub shaft 30 journaled in the arms 29 of the frame 28, and a depending member 31 having a bifurcated part 32 which receives a stick 42 of the confection 41, the stick being held by spring- pressed grips 35, 36. The shaft 30 carries a transverse plate 37 with outstanding pins 38, 39 which contact in turn with cam plates 61, 62 to swing the carriers and the confections into horizontal positions, firstly beneath the hopper mouth 48 to coat one side with sprills, and then beneath the mouth 47 to coat the other side. In operation, an attendant stands behind the mirror 72 and inserts the confections in the carriers at the position B. The carriers then descend the stretch C of the conveyer, and the confections are dipped in the bath 44, drippings of coating-material being returned by the shoot 45 to the bath 44. The hopper mouths 47, 48 are controlled by fourarmed rotary members 51, 52, connected by chains and sprockets to four-armed members 53, 54 which are moved through a right-angle by each stub shaft 30 as it passes. The members 51, 52 are thus revolved through a right-angle as each confection passes and a definite quantity of sprills is deposited. The cam plates 61, 62 have curved ends to facilitate engagement with the pins 38, 39, and spring buffers 67, 68 are provided to arrest the carriers when they are released. Surplus sprills are caught by a shoot and led to a receptacle. If a customer wants a confection without sprills, a pivoted closure member for the mouths 47, 48, which is normally maintained inoperative by a spring, is temporarily moved under the mouths by a cable operated by an attendant standing at the position A for the purpose of removing the finished confections from the carriers. After the application of the sprills, the chocolate coating is cooled by an air blast. The working parts of the apparatus are exposed to the public view. A cherry 43 may be impaled on the stick 42 before coating.

Abstract: 904,039. Exposure meters. LEITZ G.m.b.H., ERNST. Oct. 18, 1960 [Oct. 24, 1959], No. 35635/60. Class 98 (1). A photographic camera comprises a photoelectric exposure meter and exposure setting members, each coupled by a differential motiontransmitting mechanism to means to mechanically and electrically creating relative movement between an exposure meter indicator and an index mark, said two means being operable below and above a predetermined light value reading respectively. In the camera shown, the exposure meter comprises a photo-cell 3 and a rotatable measuring mechanism 4 which has a pointer 5 which moves in accordance with the light intensity relative to an index Sa. The mechanism 4 is connected to a differential gear arrangement which comprises parts 6, 7, 8. Part 7 is coupled by means of lever 9 and rod 12 to a control cam 13a on a diaphragm aperture control ring and part 8 is coupled via levers 15, 14, 16 to a cam 19a for controlling the exposure time and to means 17, 18 for adjusting a diaphragm in front of the photo-cell 3. Springs 11, 22, 23 hold levers 9, 16 against rod 12 and cam 19a respectively. The setting means are adjusted until the pointer 5 is adjacent the index 5a. This is done mechanically by the movement of gear part 6 unless a projection 4a on the mechanism 4 abuts a stop 4c on the camera, in which case on adjustment of the sealing means gear part 8 moves to rotate rod 15 and move slide rod 14 so that the photo-cell diaphragm aperture decreases which in turn results in the photo-cell current decreasing and the pointer 5 rotating. Cam 19a can be adjusted relative to the exposure time setting knob 21 to allow for the film sensitivity. Rod 14 may control a variable resistance in the exposure meter circuit instead of a diaphragm. In another alternative embodiment the mechanism 4 is stationary and the index mark Sa movable.
