Title: A Current Responsive Thermally Actuated Device.
IPC: H01H71/16
Filed: 1967-01-13
Abstract: 1,169,462. Temperature responsive actuating elements. LICENTIA PATENT-VERWALTUNGS G.m.b.H. Jan. 13, 1967 [jan. 18, 1966], No.1969/67. Heading G1D. [Also in Division H1] A bi-metal releasing element 2 in an automatic circuit breaker is heated both directly by the current flowing through it and indirectly by a heater 1 in parallel with it and joined to it in heat conducting manner, the resistances of the bi-metal and heater being chosen so that the current is divided between them in such a way that for currents less than six times the rated current the movement of the bi-metal is predominantly due to indirect heating and for Currents above this value it is predominantly due to direct heating. The trapezoidal bi-metal 2 is welded to the U-shaped heater 1 at the shaded areas and the heater is stepped to leave an air gap between them elsewhere. In a modification Fig. 3 (not shown) using a rectangular bi-metal the heater is provided with conducting wings (1a) surrounding the bi-metal so that as the latter moves heating is not materially altered; bi-metal and heater normally lie in contact. In another form Fig. 4 (not shown) suitable for low currents the bi-metal and heater each have three legs, the central leg providing the actuating force. For a current rating of about 100 amps. the bimetal resistance is about 10 times that of the heater; for 30 amps., 15 times; and for 200 amps., about 7 times. The heater may be of iron and have a positive temperature coefficient of resistance so that the current ratio will change at heavy currents.

Title: Improvements in the method of producing punching-out cutters
IPC: C14B5/02
Filed: 1964-01-16
Abstract: Steel strip for bending into the form of punching-out cutters for sheet material is formed with at least one tapered edge and is then cooled from the hardening temperature in such a way that the body of the strip cools at a rate slightly below critical while at the cutting edge the critical rate is exceeded.  The strip may then be tempered.  A particular composition exemplified consists of .carbon.0.7 .manganese.0.25 .silicon.0.25 .iron.balance It is differentially cooled from about 830 DEG C by passing through a quenching medium at a rate three times that necessary for complete hardening. The strip may be given the desired cross-section by passing it between suitably shaped rolls.

Abstract: 821,687. Step-by-step conveyers. SMIDTH & CO. A.S., F. L. Jan. 20, 1956, No. 2025/56. Class 78 (1). [Also in.Group XII] Cement clinker is delivered from a kiln through a shaft 1 on to a gas-permeable support 2 constructed as described in Specification 642,426 and is moved over it by reciprocating wedge-shaped members 3. These members are connected to a frame 4 resting on rollers 5 which is reciprocated by an eccentric and connecting rod mechanism. Clinker falls from the support 2 on to a similar support 2<SP>1</SP> over which it is propelled by members 3<SP>1</SP> which are reciprocated at a rate lower than that of the members 3. Chambers 19, 20 which are separated by a wall 13 provided with an opening 14, are disposed below the supports 2, 2<SP>1</SP>, respectively. Air, or other gas under pressure, is supplied to the chamber 19 through an opening 12. Some of this gas passes up through the clinker on the support 2 and cools it, and some passes through the opening 14 into the chamber 20 to cool the deeper layer of clinker on the support 2<SP>1</SP>. The air, which has been heated by the clinker, may pass through the shaft 1 and be used as secondary air for combustion in the kiln. The apparatus may be used for cooling hot agglomerate or lime.

Title: Means for separating mixtures of light particles having different terminal velocities in air
IPC: B07B4/02
Filed: 1944-02-04
Abstract: 574,506. Pneumatic separating. JONES, C. R. Feb. 4, 1944, No. 2115. [Class 117] Light particles having different terminal velocities in air are separated by liberating a small uniformly dispersed portion of the material so that it may fall freely through still air in a tower and collecting the fractions selectively at the foot of the tower. The materials may be distributed by means of a sieve a, to which an intermittent jarring movement is imparted by a spring-pressed rod rand snail cam u. The material is supplied to the sieve from a hopper 14 and spread by an endless band 15 with blades 16. At the bottom of the tower are disposed a number of shoots 17, 18 alternately arranged and each provided with a discharging screw conveyer 41, 42. Flaps 21 are hinged to partitions 19, and are actuated so as to cover the shoots 17, 18 alternately. The flaps are actuated in timed relation to the sieve tapping device by means of a bar 23, link 24, lever 28 and tappets 33, 34 on intergeared wheels 37, 38. The tappets are adjustable angularly, and a spring 30 provides a snap action on the lever which moves the flaps rapidly from one position to the other. In a modification, Fig. 1 (not shown), which may be used for determining the terminal velocities of the particles, the collecting device is a travelling band, and the bottom of the tower has a narrow slit for discharging the falling material on to the band in narrow strips. The width of the slit may be adjtisted by sliding plates, and the height of the tower by making it in telescopic sections.
