IPC: C10B7/14
Filed: 1923-02-13
Abstract: 193,061. Trent Process Corporation, (Assignees of Trent, W. E.). Feb. 13, 1922, [Convention date]. Charging.-Fuel is made from comminuted coal with or without a binder such as hydrocarbon oil by forming a number of openings in the mass and applying heat, preferably in the form of hot gases, to the walls of the openings. A series of cylindrical containers A with perforated bottoms B<2> are supported on trucks C having rods D<1> which serve, when the containers are charged at the filling station B<5> by a feeder F and the charge compressed by a tamper G<1> to form passages or openings B<9> through the charge when the compressed mass is lifted at the station H from the support C to be transferred to the heating apparatus. The Specification as open to inspection under Sect. 91 (3) (a) states that the comminuted coal may be formed into balls or blocks of half an inch diameter and these bodies placed in the container so that passages exist between them due to their shape. This subject-matter does not appear in the Specification as accepted. Specification 151,236, [Class 50, Fuel, Manufacture of], is referred to.

Title: Heat operated mechanical actuator
IPC: H01J17/26
Filed: 1960-07-20
Abstract: 984,268. Gas-springs. J. E. LINDBERG. May 9, 1961 [July 20, 1960], No. 4328/64. Divided out of 984,266. Heading F2S. [Also in Divisions B7 and G1] A heat-operated mechanical actuator, e.g. for retracting and lowering landing gear and controlling flaps &c. of aircraft, comprises a closed and sealed chamber 150 having fixed and movable end walls 155, 156 respectively which are connected by an extensible side wall in the form of bellows 151, a gas transfer substance 160, e.g. zeolite or metallic hydride, contained within the chamber 150 and which emits or takes in gas with a change in temperature, and electric heating means such as a filament 161, battery 162, and potentiometer 164 to heat the substance 160. The latter may be of the kind which will emit or take in gas respectively with an increase or decrease in temperature or vice-versa. Alternatively a substance may be used which, when heated above a certain temperature, will emit a substantial volume of gas without combustion or detonation the reaction being irreversible. Fig. 4 shows an actuator located between a body 165 and an axle 167 contacts 170, 171 meeting to complete the electric heating circuit 161, 162, 164 and increase the internal pressure within the chamber 150 after a predetermined degree of contraction of the actuator. In a modification, Figs. 5, 6, not shown, the contact 170 is replaced by a resistance which extends vertically from the heat transfer substance 160 and which, after a predetermined contraction of the actuator, is wiped by the contact 171 so that the current through the filament 161, and the corresponding pressure within the chamber 150, progressively increase as the body 165 approaches the axle 167. A suspension system for a vehicle combining four actuators of the kind described with reference to the latter modification, is also described (see Division B7). Specification 961,146 also is referred to.

Title: Feeding apparatus for flexible materials
IPC: B21F23/00
Filed: 1960-02-08
Abstract: 932,909. Automatic tension control. WUNDERLICH SPRING MACHINERY CO. Feb. 8, 1960 [Feb. 13, 1959], No. 4392/60. Class 38 (4). [Also in Group XXII] In an apparatus for intermittently feeding flexible material the material is fed to the apparatus in a slack condition from a feeding means under the control of an automatic system which maintains the feed rate between upper and lower limits which are independently adjustable. In an embodiment, a reel from which a wire is being withdrawn is driven by a motor 20 through a variable-ratio gear box controlled by a motor 36. The wire passes in a slack loop to a wire cutting and spring-forming apparatus driven by a motor 7. Movement of the wire in the vertical plane causes an upper contact 22 to be engaged by the wire or a lower contact 24. A current through the contact 24 energizes a relay coil R3 to close a contact R3-1 in the supply to motor 36 so that the ratio of the gear is altered to slow-down the rate of feed of the wire. Conversely, when the wire engages contact 22, the rate of feed is increased. The wire is also circumscribed by a metal loop as that a sudden increase in the wirefeed, occasioned by a turn flying off the reel, causes a current to flow in a relay coil R2 to actuate relay contacts R2-1, R2-2 to deenergize relay coils R1<SP>1</SP>, R<SP>1</SP> to cut-off the supply to motors 20, 7 through contacts R1-1-R1-3, R1<SP>1</SP>-1, R1<SP>1</SP>-3. The motor 36 moves the sliding-contact 52<SP>1</SP> of a potentiometer 52 to a position representative of the reel-speed. Potentiometers 50, 48 are manually set to the limiting speeds of the reel and the tapped voltages are compared with the voltage at tapping 52<SP>1</SP> in the base-emitter circuits of transistors 280, 282 respectively. When the motor 36 reduces the speed of the reel to the lower limit the transistor 280, through a transistor 282, energizes a relay R5 so as to open a contact R5-1 and de-energize the motor 36. Similarly at the upper limit of reel-speed transistor 298 through a transistor 300 energizes a relay R6 which de-energizes the motor 36 through a contact R6-1. To start the motors 20, 7 pushes 44, 44<SP>1</SP> are momentarily depressed energizing relays R1, R1<SP>1</SP> to close hold-on contacts R<SP>1</SP>1-1, R1-1. U.S.A. Specification 2,836,205 is referred to.
