Title: Improvements in or relating to circuit arrangements for sampling signal element combinations, more particularly start-stop teleprinter signals
IPC: H04L25/20
Filed: 1951-06-29
Abstract: 733,682. Code telegraphy. SIEMENS & HALSKE AKT.-GES. June 29, 1951 [June 30, 1950], No. 15525/51. Class 40 (3). In an arrangement for detection and regeneration of the elements of start-stop teleprinter signals by means of continuously produced scanning or sampling pulses, which are generated independently of the reception of a start element, the frequency of the sampling pulses is an integral multiple of the element frequency and after a sampling impulse has been selected, following the reception of the start element, solely the sampling impulses following at intervals corresponding to the length of a signal element are rendered effective, and the intervening impulses are effectively suppressed. When the armature e of the receiving relay E moves to its spacing contact in response to the start element received over the line L1, a relay A is energized after a delay corresponding to half the time of a signal element and the first closure of contact k of relay K operated at a frequency f1 operates relay S to actuate its armature s to pass the start element to the line L2. An impulse passed over contacts a1, k, irrespective of the position of the contact member e, energizes winding H1 of a relay H. The contact hII of the relay closes a charging circuit for winding HII of the relay H, and the capacitor C2 is such that relay H is held energized for a period slightly less than that of a signal element so that at contact hI intervening pulses at contact member k are withheld from the relay S. The closure of contact aII of the relay A energizes a relay B which, at contact bI, provides an alternative energizing circuit for relay A, and the value of the capacitor C1 is such that relay B is held operated for a period corresponding to the centre of the start element to the centre of the stop element of a signal combination, i.e. an interval equal to the length of six signal elements. When relay B releases, the contact member e will be on the mark contact (positive) so that relay A releases and the circuit is inoperative until the advent of the start element of the subsequent code combination. In a modification, Fig. 3 (not shown), for synchronous operation, the armature s of Fig. 1 controls a transmitting relay over an armature operated by a relay operated at the signal element frequency and phased relative to the operation of the relay K, Fig. 1, so that the pulses produced by the synchronizing relay occur between pulses produced by the relay K. The relay K and the synchronizing relay referred to in connection with Fig. 3 (not shown), may be replaced by static switching means, such as controlled rectifiers or valves, a rectifier arrangement being described in connection with Fig. 4 (not shown).

Title: Pulse rate indicator
IPC: A61B5/024
Filed: 1976-04-15
Abstract: 1497490 Pulse rate monitor INTERNATIONAL STANDARD ELECTRIC CORP 15 April 1976 [17 April 1975] 15668/76 Heading G1N(E) In a device for monitoring the pulse rate of a patient and comparing it with a previously determined average rest pulse rate, an indicator indicates visually or audibly the instantaneous pulse rate level, that is, rest rate, safe exercise rate, or too rapid (dangerous) rate. The device may be attached to the wrist or the forehead of the patient Figs. 5, 6, 7 and 8 (not shown). The pulse sensor 7 may be a silican piezoelectric transducer, or a piezo-electric strain gauge. Alternatively ultrasonic waves may be used. The sensor's output is fed via an amplifier 210 and a shaper circuit 222 to a counter 230. At the end of a pre-set period the contents of the counter is transferred through gates 240 to a shift register 260 in response to a pulse from a clock 270. After a delay caused by a delay 250 the counter is reset by the clock 270. When a pre-set number of counts have occurred the averaging circuit 280 processes them to provide an average value. This averaged value is applied to a comparator circuit 290 and is displayed on a device 200. The display device 200 may operate green, amber or red lights possibly in the form of light emitting digital pulse rate indicator. The averaging unit may be set manually if the rest pulse rate is known by the operator. During use the pulse rate is applied through the transfer gates 240 to the comparator 290. There it is compared with the sum of the rest pulse and a fixed increment (i.e. 50). The comparator's output is used to operate the appropriate part of the indicating device 200.

Abstract: 612,298. Ironing-boards. REA, D. B. May 23, 1946. No. 15689. [Class 138 (ii)] [Also in Group XXXVI] An ironing-board comprises two frames 1, 2 which are connected together at one end and lie in spaced parallel relation, each of the frames being filled in with openwork material 3, 4, such as expanded metal, wire mesh or the like, so as to allow free access of air to the ironing-blanket used with the board. Both frames 1, 2 are formed of angle-section metal, one frame 2 being of tapered form in plan for ironing such tubular garments as sleeves and skirts, and the other frame 1 being rectangular in plan for ironing other or larger articles. Each frame is filled in with panels 3, 4 of openwork material which are spot-welded to the frame and are additionally supported by cross-bars 10 on the frame. Instead of the cross-bars 10, metal plates having pressedup projections are welded to the side members 6, 7 of the frames, the projections serving to space the openwork panels from the plates. The connection between the frames at one end consists of a pair of U-shaped brackets, 5 which are formed from angle-section material and disposed with their limbs extending lengthwise of the frames as shown in Fig. 4; bolts 12 secure the frames to the limbs. End members 13, 14 of angle-section are welded between the side members 6, 7 of each frame, and a metal end panel 21 is secured by screws 25 to these end members so as to provide an end closure for the unit. Strips 23, 24 of sponge rubber, etc., which are interposed between the panel 21 and end members 13, 14, are arranged to project beyond the upper and lower faces of the frames so that, whichever of these strips is lowermost when the board is in use, grips the surface on which the board is rested. Buttons 27 are provided on the brackets 5 for securing the attaching tapes of the ironing-blankets. The brackets 5 are also provided with sockets 28 for receiving removably one end of a rail 29 for guiding the supply cable of an electric iron, the opposite end of the rail being formed with a hook. The end panel 21 is fitted with an electric socket, switch, and signal lamp, the socket being adapted to receive the plug of the supply cable of an electric iron, and the lamp providing a signal when the switch is closed and current is flowing to the iron.

Valves actuated indirectly.-A drinking bowl 1 supported in bearings 2 by journals 3 is provided with rearward extension 3 surrounding an enlargement 5<a> at the bottom of a water supply pipe 5. A valve 6 held closed by a spring 7 and the water pressure is fitted in the enlarged end of the pipe and is adapted to be engaged by the end of a set-screw 9 fitted in the rear of the bowl or by the bowl itself. A projection 10 limits the upward movement of the front of the bowl.
