Abstract: 874,636. Davits. MAREPA TRUST Ltd. Dec. 3, 1959 [Dec. 10, 1958], No. 39760/58. Class 115. A gravity davit has an arm 16 pivotally supported on links 13, 15 and has sufficient lateral stability so as not to require side guides. The links 15 are widely spaced apart and are pivotally connected to the pillar 11, at 14, and to the arm 16, at 18. The link 13 is pivotally connected to the pillar 10, at 12, and to the arm 16, at 17, by means of a lost motion connection 13a. Flexible stops 22 are provided to arrest and limit the outboard movement of the arm 16.

Title: Electrode
IPC: A61B5/00
Filed: 1959-11-24
Abstract: 882,143. Electrode assembly. BECKMAN INSTRUMENTS Inc. Nov. 24, 1959 [Feb. 6, 1959], No. 39771/59. Addition to 838,980. Class 37. In an electrode assembly in which spaced measuring and reference electrodes are arranged in an electrolyte separate from a medium on which measurements are to be made by a selectively permeable membrane as described in the parent Specification, the maximum diameter of the measuring electrode is of the same order of magnitude or smaller than the thickness of the membrane. The assembly is shown, Fig. 1, installed in a needle 10, having a body 11, flange 12 and pointed hollow tube 13. The lower end of the assembly, Fig. 2, comprises a closed tube 18 of non-conducting material such as glass with a conductor 20 serving as the sensing electrode sealed in its end, the conducting material being preferably platinum. The conductor is encased in a silver jacket 21 for strength, and the tip is made flush with the end of the tube and the outer surface of the end 19 is covered with minute pits. A tube 23 of conducting material such as silver, serving as a reference electrode is cemented to tube 18 and is formed with an annular ring 24 at its end with an adjacent conical section 25. A membrane 27 is positioned over the end 19 and ring 24 thus defining an annular space 26 which is filled with electrolyte and so a thin film is supported by the pitted surface 19. Such an assembly can be made small enough to fit into an hypodermic needle and thus can be used to determine the oxygen content of the blood; in such a case the membrane may be of polyethylene. The sensing electrode 20 is made the cathode and the reference electrode the anode and the electrical characteristics of the cell are affected by the quantity of oxygen passing through the membrane. The cell current is directly proportional to the quantity of oxygen passing into the electrolyte and a typical circuit is shown in Fig. 4. The particular electrolyte used depends on the electrode materials and substance to be detected. The membrane is held in position by a sleeve 30 having a frusto-conical end 31. The tube 23 is cemented in an inner shell 35 which has an externally threaded housing at its upper end into which project the tube 18 and conductor 21. An insulating sleeve 37 is fitted around the tube 18 over the end of which the conducting pin 38 is fitted, having an electrical connection with 21. In a modification, Fig. 3 (not shown), a smooth outer surface is provided for the instrument, suitable for use in a catheter. The membrane may be made of two or more layers to reduce effects of temperature, viscosity and solubility of the constituent under investigation.

Type-wheel machines; hammer impression. arrangements.-An embossing machine for sheets of metal or plastics material comprises a rotary die head 24, Fig. 1, including pairs of coacting die members 26, 28 squeezed together by respective ram mechanisms 34 to emboss the sheets said ram mechanisms being provided with interposers 50 having sections 56 and 54 of different thickness selectively positionable between a die plunger 42 and an actuating pin 40 to control the pressure exerted thereby and an electrical switch S, Fig. 3, operating an electromagnet 68 to effect the positioning of a selected section thereof. The embossing impression is effected by a rocker arm 52 pivoted at 53 and oscillated by a link 55 mounted on a crank 57. Slidably associated with the rocker arm is the actuating pin 40 having on its upper end a slotted head 41 receiving said interposer 50, mounted slidably within said head and provided with a slot 74 to receive a guide pin 72. Mounted on the thicker section 56 is a pin 62 received in a slot of a lever 58 articulated via a link 64 to the plunger 66 of the electromagnet 68. Operation of the switch S energizes the electromagnet to displace the interposer 50 to present the thicker section 56 within the slotted head 41 to increase the pressure for embossing metal sheets. The thinner section 54 is interposed between the pin 40 and plunger 42 for embossing plastics materials. The initial embossing pressure conforming with the thickness of sheets embossed is adjusted by turning an adjusting nut 37 to raise or lower the pin 40 with respect to the die members 26, 28.
