Abstract: 1487208 Toothed gearing MANNESMANN AG 11 Sept 1974 [18 Sept 1973] 39669/74 Heading F2Q [Also in Division E1] In a transmission assembly which may be used for driving a cutting head of an underwater suction excavator, the assembly includes a gear transmission 3 having at least one motor 11, a housing 4, and an output shaft 2, to which is rigidly coupled a driven work-shaft 1, and the output shaft 2 supports the housing 4 by means of bearings 5 and 6, the output shaft 2 being also mounted in a self-aligning bearing 7 anchored in a stationary frame or "ladder" 30, and the housing 4 is restrained against rotation by an articulated torque-reaction coupling 9, thereby permitting the axis of the rotating work-shaft 1 to be deflectable through a limited angle without adverse effect upon the transmission. The work-shaft 1 carries a cutter head 32 and is also mounted in a radiallyyieldable elastic bearing 31. A thrust bearing 10 permits angular deflection of the shaft axis about the same pivoting centre as that for the self-aligning bearing 7. The torque-reaction means 9 may comprise a toothed coupling having two annuli of crowned spur teeth engaged by a sleeve carrying two sets of internal teeth. A number of motors 11, 12 &c. may jointly drive a common gear-wheel 17, followed by two stages of epicyclic reduction gearing, comprising gear elements 19, 21, 22 and 24, 26, 27, in which annuli 22, 27 are secured to the housing 4.

Abstract: 906,641. Staging for workmen in mines. ALIMAK-VERKEN A.B. Dec. 12, 1958 [Dec. 18, 1957], No. 40157/58. Class 20 (2). [Also in Group XXIV] A platform 6, Fig. 1, for workmen in mines, is raised by means of driving mechanism 8 on a rack 11 on a guide-rail 4 fixed to the rock face, and having a hinged section 4a, Fig. 1a, which is adapted to be moved with the platform under the shelter of the rock during blasting. The hinge may have a horizontal or vertical axis. The driving mechanism 8 is driven by an electric motor having a control 21 on a pillar 22 on the platform, which also carries a protection shelter 24. The driving mechanism comprises three pinions 10 engaging the rack 11 and driven by worm gear 41, Figs. 2b and 2c. To allow the pinions to turn relatively in order to compensate for irregularities in the pitch of the rack the pinions 10 are rotatably mounted on shafts 39 by means of flanges 50 having slots 53 in which engage pins 52 held against projections 51 in the pinions by springs 54. This mechanism can be driven by hand. One section of the rail 4 is mounted on a mobile trolley 1 and other sections are bolted to the wall of a mine shaft. The platform has a hinged extension 16. In the modification of Fig. 1a an operator is seated at 56 below the platform 6 which can be pivoted by means of adjustable struts 59 always to take an horizontal position whatever the inclination of the guide rails 4. The sections of the rail 4 are connected together at the front by bolts through interengaging ears each bolt having a handle with a finger engaging between two ears to prevent disengagement. A bolt also connects the sections at the rear. A vertical shaft is driven upwardly first by drilling and blasting from the platform on a rail section on the trolley. This rail section is then connected to the lower end of a rail secured to the shaft wall and the platform transferred to this rail, the trolley removed and the driving of the shaft continued with the necessary extension of the rail. Specification 906,642 is referred to.

Title: Incinerating waste disposal devices

Filed: 1973-08-24
Abstract: 1434401 Incinerator closet LA MERE INDUSTRIES INC 24 Aug 1973 40193/73 Addition to 1083878 Heading E1C [Also in Division F4] An incinerating waste disposal unit comprises a seat 32 with a cover 34, a receptacle 87 having a trap door 86, and a combustion chamber 38 disposed below the trap door and including a gas burner 42. Air for combustion enters the burner 42 via a pressurizer 58 and a duct 46 and via apertures 89 in the trap door 86. A fan 56 draws gases through an exhaust outlet 60. Movement of the seat 32 actuates a timing device 83 for the operation of the burner and of the fan. The disposal unit operates in a combustion cycle and in a subsequent cooling cycle. In the first said cycle a valve 62 is opened allowing the entry of secondary air from a chamber 29 surrounding the receptacle 87 into the exhaust duct 60. In the cooling cycle valve 62 is closed, the exhaust blower 56 drawing cooling air supplied by pressurizer 48 from the burner outlet. A control system for controlling the operation of the unit includes a seat switch 116 which winds a timer 83 and energises blower motor 58. Timer 83 is a double pole single throw timer. Assuming the presence of flow of air from the blower, a sail switch 114 is closed so that a variable vent solenoid 64 is actuated to open valve 62 and gas valve 54. At the same time the igniter coil 45 is energised so that spark plug 44 actuates burner 42. Burner 42 will continue to burn throughout the burning cycle, as controlled by timer 83 unless seat cover 34 is reopened thereby opening seat switch 116 or unless sail switch 114 opens due to an absence of draft from blower 56. At the end of the said cycle valve 54, igniter coil 45 and solenoid 64 are re-energised. Blower motor 58 continues to run, cooling the chamber 38, until turned off by the timer 83.

Title: Control system for the lifting piston of an hydraulic lifting device

Filed: 1959-11-27
Abstract: 918,786. Lifts. DOVER CORPORATION. Nov. 27, 1959, No. 40372/59. Class 78 (3). [Also in Group XXIX] A control system for an hydraulic lift of the kind in which a car moving ram 12 is fed by a constant outlet pump 18 from a reservoir 24, has a by-pass valve 36 which is connected between the pump outlet line 26 and the return line 34, and is provided with a valve member 54 controlling flow between the inlet and outlet ports 38, 42, the member 54 being urged to an open position by an adjustable spring 72, and a closed position by fluid pressure transmitted to the chamber 62 from the valve inlet port 38, the arrangement being such that the position of the member 54, and thus the speed of movement of the ram 12, is determined automatically by the pressure in the system. Limit switches 190, 202, 210, 214, 218 together with manual switches and relays (Fig. 2, not shown) operate the pump motor 20 and solenoid valves 168, 110, 32 to effect the following cycle of operations. On receipt of a start signal and with valve member 54 open, motor 20 is energized and valve 110 is opened whereby pressure is transmitted to chamber 62 via lines 94, 95, 98 and member 54 is moved towards its closed position at a speed determined by the setting of a needle valve 96. As the valve 36 closes the increased pressure in line 26 opens check valve 28 and the ram commences to lift the car 10. At a predetermined point in the travel of the car, valve 110 closes so equalizing the pressures in chambers 62, 64, whereafter spring 72 moves member 54 towards its open position at a speed determined by the setting of a further needle valve 106, and the member 54 stops in a position in which the pressure differential between chambers 62, 64 balances the effect of spring 72. During this operation of the by-pass valve 36 the ram is slowly brought to rest and the motor 20 is de-energized. Lowering is effected by opening valve 32. In the event of the car settling as a result of leakage, valve 168 is opened, valve 110 remains closed and the motor 20 is re-started. Pressure then flows through lines 94, 176 to chamber 62 and the member 54 is moved rapidly to its closed position. Check valve 28 then opens and the ram is extended until the correct level is attained whereupon valve 168 is closed and the motor 20 is de-energized. If an excess pressure is developed in the system the pressure applied to valve 126 via line 94 moves piston 130 to the left so connecting line 94 with chamber 64 and exhausting chamber 62 via lines 98, 154. Valve 36 is thus rapidly opened and the excess pressure is relieved. Figs. 3-5 (not shown) illustrate modified bypass valves operating similarly to valve 36.
