Title: Improvements in or relating to installations for electrically driving and braking hoisting devices
IPC: B66C13/24
Filed: 1961-03-01
Abstract: 905,619. Control of D.C. motors. SCHNEIDER, K., and LORFEVRE, J. Y. March 1, 1961 [March 2, 1960], No. 7483/61. Class 38 (3). [Also in Group XXXV] A D.C. hoist motor M has its armature 1 and field winding 10 each connected to an A.C. source through an associated converter C, R, comprising semi-conductor rectifiers controlled by devices 8, 15, each adapted to supply voltage pulses to its associated converter. A speed responsive voltage and a reference voltage are fed to comparator 17, the error signal being transmitted through a second comparator 19 to the controller 8. The comparator 19 also receives a current-responsive signal to restrict the maximum value of the armature current. The comparator 17 transmits a signal to a bi-stable flip-flop element 23 for determining the direction of field excitation in accordance with the sign of such signal. A function generator 21 varies the field current as a function of the speed so that the product of the speed and flux remains constant above a predetermined speed. When the reference voltage is reduced, the field excitation is reversed and the converter C acts as an inverter, so that the motor is regeneratively braked until it is stabilized at a lower speed.

Filed: 1942-06-03
Abstract: 557,335. Annular drills. GRUENBERG, J. June 3, 1942, No. 7575. [Class 83 (iii)] An annular boring tool 4 has a number of cutters which come into action successively, either singly or in pairs so that each cutter removes only a fraction of the total material removed from the work. The cutters 5 ... 10 make overlapping cuts of the form indicated in Fig. 3. the cutters 5, 6 coming first into operation and the cutters 9, 10 acting last on the outer and inner boundaries respectively of the cutter. Protrusions 11 ... 13 on each side of the tube 4 may be provided with balls to steady the drill and maintain the alignment. For large diameters the tube 4 may be built up of sections with longitudinal joints such as 14, 15. When a hole is formed completely through the work the inner core becomes detached and may be utilized. The cutting edges are formed on the ends of spiral webs extending along the inside and outside of the tubular drill, the webs being either formed integrally with the tube or secured thereto. The number of cutting elements may be varied. In a modification the tool body may be provided with inclined slots instead of spiral ribs, the slots being fitted with adjustable cutting elements.

Filed: 1945-03-26
Abstract: 633,616. Collapsable buildings. AJNE, C. A. March 26, 1945, No. 7578. [Classes 20 (i), 20 (ii) and 20 (iv)] [Also in Group XXIII] In a building structure having a skeleton framing comprising intersecting framing elements maintaining building sections in place, the tightening between adjacent building sections is effected by framing elements inserted in grooves in opposite edges of the building sections, and by framing elements intersected by the framing elements in the grooves, coupling members between two aligned framing elements at the point of inter-connection with a third being carried by said aligned elements and extending through the intersecting element. Fig. 2 shows a framing element 10 inserted in opposite grooves of building elements 4, 6 and aligned elements 14, 16 coupled by a screw 29 passing through the element 10. The framing element 16 is formed of two similar grooved batons 18, 20, Fig. 3, assembled to provide a central'channel 26 in the element. A cylindrical chamber closed by a bored plug 30 houses the head of the screw 29 which is accessible by a screw-driver 38 (see Group XXIII) passed through the channel 26. The element 14 is constructed similarly to the element 18, the end of the screw 29 being received in its channel 26. The ends of both aligned elements 14, 16 have tongues 34 which fit into grooves 36 in the intersecting element 10. Two modifications of this method of coupling in which machine screws are used instead of wood screws are described. In one of these modifications the framing elements are of circular section and are sheathed in metal. Instead of being inserted in the edges of blocks 4, 6 the element 10 may be inserted in opposite grooves in a pair of half-posts which are pressed together by the tightening of the screw 29. Fig. 11 shows another method of coupling in which, instead of a screw, hooks 80, 80a secured to the elements 14, 16 by screws, are used. The hooks are accommodated within an aperture 88 provided in the intersecting element 10. A further, smaller, cavity 89 in the element 10 allows for movement of the hook 80a in engagement and disengagement. Fig. 13 shows a coupling consisting of a rotatable locking hook 102 having a shaft 104 journalled in a bracket 106 on one element 16, and a stationary locking member 108 secured to the other aligned member 16. The hook consists of a plate attached to the shaft 104 provided with a flange 110 which engages the member 108.

Patent GB-751131-A (GB)
Title: Improvements in and relating to a tubular oil heater
IPC: C10G9/20
Filed: 1954-03-18
Abstract: <PICT:0751131/III/1> <PICT:0751131/III/2> In a tubular furnace for heating hydrocarbon oils the side walls of the combustion chamber 10 are composed of a number of sloping faces 14 arranged in steplike formation; and sets of burners 18 are disposed along the steps 12, the burners being directed so that the flames therefrom sweep over the sloping faces.  The hydrocarbon oil flows through horizontal tubes 30 connected in series and mounted between, and parallel to, the side walls so that they are heated by thermal radiation therefrom.  The firing of each burner is adjustable independently of the others.  If the burners are all fired at the same rate, the furnace walls as a whole can be very uniformly heated.  On the other hand, by altering the firing rate of any set of burners, or the firing rate of individual burners in any set, differing parts of the walls of the furnace can be heated to different temperatures, and thus the rate of supply of heat to different sections of the tubes can be controlled.  In the embodiment shown, the hydrocarbon oil flows in two separate streams through the furnace, each stream flowing through a bank of tubes 28 arranged in the combustion gas outlet 26 before it enters the tubes 30 in the combustion chamber. The tubes may, if desired, be arranged vertically.  An embodiment is also described wherein the sloping faces of the combustion chamber slope inwards downwardly, the burners direct their flames downwards, and provision is made so that part of the hydrocarbon oil may be subjected to radiant heating only.
