Title: Improved method and apparatus for treating and incinerating sewage sludge or the like waste material
IPC: C02F11/06
Filed: 1935-08-16
Abstract: 463,037. Refuse-oonsuming furnaces. NICHOLS ENGINEERING & RESEARCH CORPORATION. Aug. 16, 1935, No. 23082. Convention date, April 26, 1935. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 18, 1936.] Addition to 432,198. [Classes 51 (i) and 51 (ii)] A modification of the method described in the parent Specification for treating sewage sludge &c. consists in subjecting the gases evolved from the material under treatment in a furnace to a temperature, 1200 to 1500‹ F., sufficient to eliminate noxious odours therefrom during their passage through an intermediate zone or zones of the furnace. The material is fed from a hopper 12 into a furnace of the superposed hearth type having a vertical rabble shaft with stirring arms 30, 31 through which cooling air is passed and afterwards led to a recuperator (not shown) traversed by waste gases for heating the air. The material is dried on the upper hearths and incinerated on lower hearths, the residues being discharged at 14. Air is supplied from the recuperator and pipes 24a, 24b to openings 26 in the side walls of the furnace and delivered over the hearths. As shown in Fig. 3, the openings 26 are provided with burners 48 to which the supply of air for combustion is controlled by dampers 45, 46. The sewage sludge before admission to the hopper 12 is filtered to form a filter cake the moisture content of which is between 60 and 85 per cent. The burners 48 are put into or out of operation according to the nature of the material being treated. British Specification 22022/10, [Class 51 (ii)], and U.S.A. Specification 1,669,925 are referred to.

Title: Improvements relating to vehicle brakes
IPC: F16D65/54
Filed: 1946-08-06
Abstract: 614,845. Compensating for wear in brakes. LUCAS, Ltd., J., and IFIELD, R. J. Aug. 6, 1946, No. 23239. [Class 103 (i)] In a brake applied by liquid pressure and in which there is a very small clearance between the friction surfaces in the " off '' position, automatic means for compensating for wear of the friction surfaces comprises a plunger f movable in an operating cylinder d against a substantial frictional resistance provided by packings g, and a piston i acting on a friction member such as a brake shoe b and working in a chamber j in the plunger which communicates with the cylinder through a passage m formed in a second plunger h integral with the piston. A spring o, interposed between abutments on the inner ends of the plungers, serves to retract the piston to the " off " position determined by the engagement of a shoulder s with the plunger. This spring allows sufficient relative movement between the piston and plunger to take up the normal working clearance but, if the clearance is excessive, the frictional resistance is overcome and the plunger and piston are moved outwardly together to take up the wear. The direct liquid pressure on the unequal outer and inner faces of the plunger f augments the frictional resistance. In modifications, the piston is replaced by a diaphragm, Fig. 3 (not shown), or the piston and spring are replaced by a resilient diaphragm.

Abstract: 587,963. Knitting-machines. LAMBACH, F. Nov. 22, 1944, No. 23253. Convention date, Feb. 24. [Class 74 (ii)] A take-up device for a warp knitting-machine comprises a take-up roller 16 and a tension roller 20 for engaging the fabric 12 extending between the knitting implements and the take-up roller, the tension roller being carried at at least two spaced points thereof by a guiding mechanism which holds said spaced points in planes parallel to each other when the tension roller is displaced. In the form shown, the tension roller 20 is carried by a pair of spaced supporting members 22, 24, swingably mounted on shafts 26, 28, respectively and connected by links 30, 36, to levers 42, 48, keyed to a shaft 46 so that a uniform movement is imparted to the members 22, 24, when the tension roller is displaced. Weights 52, 54, adjustably mounted on the levers 42, 48, which are each provided with a scale 56, serve to give a rough adjustment of the tension in the fabric, a finer adjustment being obtained by a spring 58 associated with each of the levers 42, 48, and the tension of which is adjustable by means including a scale 72. The lowermost position of the roller 20 is limited by adjustable stops 82, 84. The take-up roller 16 is driven intermittently by mechanism comprising a rod 106, one end of which carries a bolt 104, Fig. 1, adjustably and eccentrically mounted relative to a shaft 90 by means including a scale 112, and the other slotted end of which is adjustably connected to an arm 124 of a member 126 swingably mounted on the shaft 26, rotation of the member 126 being transmitted to the take-up roller 16 by a pawl and ratchet and a train of gears. Another arm 130 of the member 126 rests on an extension 138 of the tension roller 20. When the tension in the fabric alters with a change in the position of the roller 20, the position of the arm 124 relative to the slotted end of the rod 106 alters at the same time so that the take-up roller 16 is advanced automatically to a greater or smaller extent until the normal tension in the fabric is re-adjusted and the tension roller returns to its original position.

Abstract: 974,142. Stapling machines. ETABLISSEMENTS J. HERBIN S.A. June 20, 1962 [July 3, 1961], No. 23694/62. Heading B4C. A stapling machine is adapted to receive at least one charge 11 of staples in the position of use and at least one replacement charge 14 in a waiting position. The machine comprises a rail 1 for supporting the charges 11, 12, Fig. 2, of staples in a working position and a pusher 2 which urges the end of the charge of staples against a stop under the action of a spring. A movable support member 20 is slidably mounted over the pusher 2 in order to support the replacement charges 13, 14, 15 and 16 of staples which are guided in a magazine formed by walls 27, 28, 29; additional charges may be mounted in spaces 17, 18. The support member is coupled to a handle 7 by means of a link 22 and the pusher 2 is connected to the support member by means of a pivoted latch 30. To load the machine, the handle is raised to the position shown in Fig. 11, the pusher 2 and support member then being moved fully to the right. The separate charges of staples are placed in the magazine so that the lower two charges 11, 12 straddle the rail 1. Upon initial lowering of the handle, the pusher 2 and support member 20 are moved, under the action of a return spring attached to the pusher, until the end of the pusher abuts the charge of staples 12 pushing them forward until the front end of the charge 11 abuts the stop 6. Continued movement of the handle causes a lug 46 on the support member to disengage the latch 30 from the pusher and thereby permit the support member to be moved under the charges 14, 16 as shown in Fig. 3. When the last staple of the bottom charges 11, 12 is used up, the blade 9 strikes the nose 42, 43 of the latch so as to re-engage it with the support member in order that, when the handle is raised, the pusher is moved again to the right and so permit the next charges 14, 16 to fall under their own weight on to the rail 1.
