Title: Method and means for treating diseases of the circulatory system
IPC: A61F13/08
Filed: 1951-06-25
Abstract: 699,152. Massage appliances. FERRIER, A. P. S. June 25, 1951 [June 29, 1950], No. ' 15056/51. Class 81 (ii). A device for stimulating the circulation comprises means for exerting a progressive compression and releasing the compression, in sequence. For treating a leg the limb 4 is wound spirally with a flexible tube 1, of normally flat cross-section, arranged so that the edges of adjacent convolutions overlap slightly, and the whole is enclosed in a non-extensible sheath or cover 6 which is tightly secured by lacing 9. Air from a compressed air cylinder 25 is passed through a reducing valve and optional heating means 23 to a changeover cock 17 which may either connect the air supply to a tube 11 and the lower connection 10 of tube 1 or may connect pipe 12 and outlet 19. The handle 18 is initially set to the first position and the admission of air to the tube 1 produces a constricting pressure on the limb which commences at the lower end and gradually extends to the upper end. On the completion of this phase the handle 18 is moved to the second position where it allows the air to escape to atmosphere. The procedure is then repeated. For treatment of the trunk or neck, a pad, formed of a tube folded in zig-zag arrangement and mounted on a flexible back member is firmly secured to the body by straps.

Filed: 1951-07-02
Abstract: 692,330. Magnetic recording and reproducing apparatus. KAUDERER, G. C. F. and KAUDERER, J. A. G., [trading as HANDELSVENNOOTSCHAP ONDER DE FIRMA TECHNISCHE IMPORT, EXPORT EN FABRICAGE AMROH]. July 2, 1951 [July 1, 1950]. No. 15665/51. Class 40 (ii). A magnetic recording and reproducing apparatus, provided with separate motors for winding an elongated record in either direction from one spool to another, has an electromagnetic disengaging device for the driving gear between a motor and the rest of the mechanism and is characterized by a slip coupling between the shaft of the motor and the wheel of the transmission driving the shaft carrying a spool. During a forward winding operation, Fig. 1, the friction of the slip coupling, arranged between the motor 1 and shaft 2, is sufficient to maintain the drive of the motor 1 through an intermediate pulley 3 to a take-up spool 4. When rewinding, a motor 9 on the shaft carrying the supply spool 8 draws the record back on to the spool 8, an electromagnetic device 10, connected in parallel with the motor 9, having drawn the intermediate wheel 3 out of contact with the shaft 2 of the motor 1. In the event of the direction of the apparatus being switched back to a forward operation, and the intermediate wheel 3 therefore brought back into engagement with the shaft 2, the slip coupling between the motor 1 and shaft 2 prevents undue friction and wear between the wheel 3 and shaft 2. The slip coupling is effected by making the shaft 2 in the form of a sleeve having a longitudinal slot and a transverse slot providing a resilient tongue which is pressed against the shaft of the motor 1 by an annular spring 18.
