Abstract: 844,630. Hollow rollers. HOT OIL HEATER CO. Inc. Nov. 30, 1956 [Dec. 2, 1955], No. 36686/56. Class 34(1)  A roll for heating, drying or cooling paper &c. comprises an inner drum 51 having re-entrant ends connected by tubes 54, 55 and apertures 58, 59 disposed between partition 50, 57. Oil for heating or cooling the roll is supplied through a pipe 47 to the space between the partitions and issues through the apertures into the annular spaces between the roll and the drum on either side of a ring 56. From these spaces the oil flows into the chambers formed by the re-entrant ends and thence through the space around the pipe 47 to exhaust. The oil flow through the roll may be reversed by means of a reversing valve 68.

[Also in Division B2] A separator for removing fragments of hard tissue material, such as bone, cartilage, gristle, scales and fins, from comminuted meat, including fish, comprises a power-driven hollow rotor 40 rotatably mounted in a casing 31 and formed in its outer periphery with helically disposed spaced cutting elements 53 defining between them grooves 55 communicating with the interior of the rotor, the outer periphery of the rotor co-acting with the inner face 64 of a pressure bar or plate 41 which extends longitudinally of the rotor and forces the comminuted meat through the grooves 55 into the interior of the rotor while the fragments of bone &c. which are wider than the grooves are retained on the rotor periphery. The casing 31 is supported in cantilever fashion, Fig. 4 (not shown) from a power unit (28) driving the rotor and is provided with a food aperture 32 surmounted by a hopper (34). The cutting elements 53 are arranged in multiple helices and, in order to intensify the cutting action of the elements on the meat and to provide additional capacity for engaging and rejecting the undesired fragments, the outer peripheral faces of the cutting elements may, as shown, be formed with twin ribs 54 defining between them relatively shallow blind grooves 56. The grooves 55 between the cutting elements are wider at e than at t to facilitate the flow of meat towards the interior of the rotor. The pressure bar 41 is clamped on a platform 59 by screws 60, its position relative to the rotor being adjustable. The face 64 of the bar is concave and defines with the rotor a funnellike pocket 65 in which the undesired fragments accumulate while being driven longitudinally of the rotor by the helically disposed cutting elements 53 towards the open right-hand end of the pocket 65 to be discharged on to a conveyer (FC), Fig. 5 (not shown). A regulator blade 63 controls the rate at which meat is fed to the pocket 65. The meat entering the interior of the rotor is discharged therefrom by means of a stationary screw-conveyer 66, 68 which co-operates with the inner surface of the rotating rotor to direct the meat towards the left hand end of the rotor where it is discharged, via apertures 69 in an end plate 44 of the rotor and via an opening 38 on the underside of the casing 31, on to a conveyer (MC), Fig. 5 (not shown). The separator may form part of a plant for producing boneless comminuted meat and including a grinder in which a dressed carcass of meat animal, poultry or gutted fish is first reduced to an agglomeration of comminuted meat and fragments of bone &c. which is subsequently treated in the separator.

Filed: 1929-12-05
Abstract: 344,078. Alternating -current commutator motors. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Stoller, H. M. ; 63, Pollard Road, Mountain Lakes, and Morton, E. R. ; 23, Schermerhorn Street, Brooklyn, both in New York, U.S.A.) Dec. 5,1929, No. 37372. Convention date, Jan. 5. [Class 35.] An arrangement for maintaining substantially constant the speed of an A.C. commutator motor 2 comprises means associated with the field winding F<2> whereby an auxiliary E.M.F. proportional to the motor speed and the source frequency, is impressed on that winding. As shown, the motor 2 has four poles, a primary winding F<1>, and a rotor of the type used on D.C. shunt motors, the winding F<1> inducing in the rotor windings currents which react on the field due to windings F<2>, so that by varying the impedance of the field, as by a rheostat 13 with the switch 7 in the position shown, speed variation can be obtained as in D.C. shunt motors. A condenser 12 in the circuit ensures the correct phase relations between the field and rotor currents. On the shaft 5 of the rotor 6 is mounted either the squirrel-cage rotor of an auxiliary asynchronous motor, or, as shown, the rotor 4 of a synchronous salient-pole motor having six poles, the stator F<3> of which is in series with the field F<2> with the switch 7 on the contact 9. If at synchronous speed of the auxiliary motor, the main motor tends to lose speed due to a change of load or applied voltage, the auxiliary machine acts as a motor and develops a back-E.M.F. which reduces the current through the field F<2> and restores the speed. Increase of speed is similarly prevented by the auxiliary machine acting as a generator.

Title: Improvements in electric starters for internal combustion engines
IPC: F02N15/06
Filed: 1928-12-30
Abstract: 307,876. Scintilla Akt.-Ges. March 15, 1928, [Convention date]. Turning - gear. - In an electric starter in which the engagement of an axiallymoving pinion is facilitated by giving the pinion an axial to-and-fro motion and a slight angular motion if its teeth clash with those of the fly-wheel, a current reversing switch for the starting motor is controlled in dependence on the to-andfro motion of the pinion shaft. As shown, the pinion R has a threaded shaft in engagement with a sleeve Z driven through a laminated friction coupling L from a sleeve W carrying the motor armature A. A reversing switch V for the motor comprises spring contact-pieces P, Q, S, T, which engage contacts G, K in the inoperative position shown in Fig. 1. On closing the circuit of an electromagnet 0 by means of a switch Y, the switch V is moved into the position shown in Fig. 3, closing the circuit of the field coils F and armature A through contacts N, M. The pinion R moves axially and, if its teeth clash with those of the fly-wheel, the sleeve Z screws backwards, acting through a sleeve H to compress springs B, C and to move the switch V into the reversing position, in which the contacts P, T engage the contacts K, G and the contacts Q, S engage the contacts D, E. The motor being reversed, the sleeve Z moves forward again, the pinion R being given a slight rotary movement into meshing position. The spring B then throws the pinion into mesh with the fly-wheel, the switch V being thrown back into the position shown in Fig. 3, and starting is effected. The switch V may be operated by purely mechanical or purely electrical means.
