Filed: 1917-02-15
Abstract: 111,013. Pinder, F. Feb. 15, 1917. Circular-saw machines. - Relates to machines for cutting-off lengths from bar or other stock of any section. The figures show a machine of the lathe type in which a circular saw P is mounted on the spindle. To the cross slide X of a sliderest is secured a sole-plate A carrying a fixed jaw B and a movable jaw C which grip the work. The jaw C is secured to a bar F which is surrounded by a helical spring G pressing the jaw C against the work and bearing on a stop E fixed to the sole-plate. The stock W is moved up against an adjustable stop L by hand or automatically by a weight or spring. The bar F passes through a frame H which carries the stop L and is secured to the bed-plate of the machine. By means of a hand lever M on a spindle carrying a pinion U gearing with a rack V on the cross slide X the various operations are effected. In the position shown in Fig. 2, the work is just out of contact with the tool and by a further upward movement of the lever M it is pressed forward and a length is cut off and falls clear. The handle is then turned down to the cross-slide and the other parts until the nuts N on the bar F strike the frame H and arrest the movement of the movable jaw C. The fixed jaw. B moves on and the work is released and again fed up to the stop. Upward movement of the handle again moves the jaw B and work up against the jaw C and so on. Modifications may be made in the details of the apparatus providing the operations described above are effected by a to and fro movement of a crossslide.

Title: Improvements in apparatus for the automatic back-suction of entrained liquid from the evaporator in absorption refrigerating machines
IPC: F25B17/00
Filed: 1927-01-28
Abstract: 265,581. Mannesmann-Kõlte- Industrie-Akt.-Ges. Feb. 4, 1926, [Convention date]. Refrigerating, absorption machines and processes for.-Solvent liquid accumulating in the evaporator of a machine operating on the reversing system is returned to the generator-absorber during the absorption period by an ejector, in which the returning vapour acts as the inducing- medium. The ejector 9, Fig. 2, is arranged in the upper header 4 of the evaporator, a single pipe 2 including the condenser 3 serving both as expulsion and return pipe for the generatorabsorber 1. The solvent is raised to the nozzle 8 through a pipe 7 reaching nearly to the bottom of the evaporator. During the expulsion period the liquid from the condenser passes around the nozzle 8 and enters the evaporator through the ports 11, which act as inducing-fluid inlets during the absorption period. The generatorabsorber 1 is provided with a device for diverting the vapour to the liquid space during absorption, comprising a closed cylinder 14 fitted with a pipe 16 depending from an opening 18 in the vapour space of a dome 12, and an open horizontal pipe 15 connected to the cylinder 14 near the bottom. During generating, vapour passes down the pipe 16 and escapes to the outlet pipe 2, whereas upon a reduction of pressure in the main vessel 1 during absorption the pipe 16 contains a column of liquid which diverts the returning vapour through the pipe 15 into the liquor. In a modification, the ejector 9, Fig. 3, is located in a shallow cup 21 which fills and overflows with liquid refrigerant during the generating period. When absorption commences the liquid in the cup is drawn into the return pipe 20, together with solvent through the pipe 7, until the ports 11 are uncovered, when the normal vapour return commences: the pipe 7 is shown as dipping into a well 22. Alternatively the ejector may be located so that the ports 11 are just submerged in refrigerant liquid in the evaporator at the end of the generating period, so that some refrigerant liquid is returned with the solvent at the beginning of each absorption period. The ejector mav be connected in the return pipe of a system having separate expulsion and return pipes.

Filed: 1938-01-28
Abstract: 510,331. Abrasive coated articles. BEHRMANNING CORPORATION. Jan. 28, 1938. No. 2842. Convention date, Feb. 6, 1937. [Class 60] In making coated abrasive articles the synthetic resin adhesive has incorporated in it an accelerating curing agent either immediately before, concurrently with or subsequent to the formation of the adhesive film on the backing and before the grains are set in the adhesive. The resin may be a phenol-aldehyde, cresolaldehyde, urea-formaldehyde or alkyd resin. The preparation of suitable resins is described in Specification 510,328. Backing material such as cloth or paper from a roll 10, Fig. 2, is coated by rolls 11 with adhesive from a jacketed trough 12 which is supplied from a jacketed kettle 14 via small jacketed kettles 19, 20, into which the accelerating curing agent is introduced by inlets 21, 22. Each small kettle is used alternately to supply the trough 12. The adhesive coated web is then coated with abrasive from hopper 28 which is pressed into the adhesive by rolls 29, 30 and passed to the curing chamber by a suction drum 32. In the modification shown in Fig. 3 a solution of the accelerator from a tank is continuously metered by an orifice meter 37 into the adhesive flowing in pipe 33, and mixed in a kettle 35. Curing is effected, for example, by heating for successive periods of one hour at 105‹, 110‹, 115‹ and 125‹F. followed by 2 hours at 130‹F. The sand-paper may be sized with a similar adhesive. Suitable accelerating curing agents are hexamethylene tetramine, alkali such as sodium, potassium or barium hydroxides, paraformaldehyde, oxalic acid or phosphoric acid. They may be used as pastes or solutions in water or alcohol. The abrasive grains may be applied by the electrostatic methods described in Specifications 378,014, 379,379 and 398,907. In modifications the accelerating curing agent may be applied to the adhesive-coated base by spraying on a solution or blowing on a powder. It may be similarly applied prior to application of the sand-size. The process may be combined with that described in Specification 510,329. Specifications 510,330 and 510,332 also are referred to.
