Title: Combined sales counter and automatic vending machine
IPC: G07F11/28
Filed: 1936-02-17
Abstract: 471,326. Coin freed article - delivery apparatus. ROGERS, H. C. I. Feb. 17, 1936, Nos. 4704 and 27167. [Classes 27 and 116] A combined sales counter and automatic vending-machine comprises a counter 1, Fig. 1, stepped to provide a forwardly projecting ledge 6 below the level of the counter top 3, and a magazine 9 containing the articles to be sold which extends rearwardly within the counter from adjacent the ledge 6, mechanism being provided so that, on the insertion of a coin or coins, an article will be delivered through or on to the ledge to a position accessible to the purchaser. The articles 10 are piled as shown in the magazine and are pushed towards the front by a weight 11 on rollers. After prepayment, an electromagnet 17 is energized and its armature rod 16 caused to move upwards, so that a plunger 12 connected to the armature bv a lever 13 is also moved up to push the end or bottom article 26 through an aperture 27 in the ledge to be grasped by the purchaser. The stroke of the plunger is less than the height of the article, so that the latter is held in the projecting position by the pressure of the following pile. The magazine is open at the rear for refilling. The electromagnet 17 is in a circuit having normally open contacts 18, 19. These contacts can be closed by the shop attendant, without requiring the insertion of a coin, by a push rod 29 which acts through a bell-crank lever 30 and vertically sliding rod 31 on a lever 20. The lever 20, when rocked downwardly, closes the contacts 18, 19. In a modification, Fig. 4, the articles 10 are arranged flatwise in the magazine, the bottom article 26 abutting against a roller 34. The armature rod 16 rocks a lever 38 to push the bottom edge of article 26 on to the top of the roller whereupon it slides over the roller and through an aperture 27 on to the ledge 6 by the pressure of the following articles and weight 11. Coin action, weight.-A coin or coins, inserted through a slot 21, drop down a shoot 22 on to the end 23 of the lever 20 and rock this lever downwardly to close the contacts 18, 19.

Title: Apparatus for measuring the human pulse beat rate
IPC: A61B5/024
Filed: 1978-02-10
Abstract: A housing (1) which can be gripped in the hand has on its front side a display arrangement (2) for displaying the measured values numerically. The upper narrow side of the housing (1) is provided with a trough-shaped depression (8), in the bottom of which is arranged, in an opening (9), an electro-optical sensor, which forms a bearing surface for one finger of the hand gripping the housing (1). The sensor contains a light source and an electrical light receiver, which generates signals corresponding to the pulse beat detected in the finger. A switch arrangement accommodated in the housing (1) measures the length of the time interval lying between two successive pulse beats and outputs to the display arrangement (2) a measured value proportional to the reciprocal value. For instantaneously switching on the supply voltage, a separate press-button switch (6) is arranged on the housing (1), or the sensor is itself designed as a press button with switch contacts. The unit has a pocket format, requires only one hand for its operation, and displays the desired measured value in a very short time. <IMAGE>
