Title: Improvements in thermostatic regulators
IPC: G05D23/185
Filed: 1924-06-06
Abstract: 228,772. Imrie, H., (Parks-Cramer Co.). June 6, 1924. Thermostats.-In a thermostatic apparatus, particularly applicable to hygrometric apparatus of the wet and dry bulb type for controlling automatically the humidity or the temperature of the air in a room, two thermo-flexible elements subject respectively to different temperature conditions are mounted upon a suitable base so as to utilize the differential action of the relative lateral movement between the middle and the ends of the two members for the purpose of actuating the energy-controlling device, e.g. a valve regulating the supply of moist or warm air. In the construction shown, two bimetallic strips 13, 24 are employed of which one, 13, is mounted at its centre upon a fixed but adjustable support 14 on the base 1, while the other 24 is freely mounted by means of swinging supports, the ends of the elements being connected by rods 33, 34, which are adjustable in length so as to vary the initial relation of the two elements. The connections between the bimetallic elements and the rods preferably comprise ball-and-socket joints 38, Fig. 5, the stems 39 of which can be clamped at different points near the ends of the bimetallic element 13, such adjustment altering the relative actuating effect of the elements on the valve and energy-controlling device, for instance, in altering the degree of humidity required. The casing formed by the base 1 and cover 3, 4 is divided by partitions 7, 8 so as to form a duct by which air from the room may be drawn over the bimetallic element 13, which is thus subjected to the dry bulb temperature, then saturated by spray from an atomizer 59 and passed over the second bimetallic element 24, which is thus subjected to the wet bulb temperature. A valve-actuating rod 43 is attached to the mid-point of the element 24, and the elements 13, 24 are arranged with the more expansible metal of each element, facing the same way so that the total movement produced is a differential one. In the arrangement shown, the end of the rod 43 operates a pivoted lever 49 which is adapted to cover or uncover to a varying degree the bleeding port of a fluid-pressure actuated diaphragm motor, which in turn regulates the supply of heat or moisture; the movement of the rod 43 may also be used to control an electric switch.

Title: Improvements in or relating to methods and apparatus for the transmission of electric signals
IPC: H04B14/02
Filed: 1951-06-12
Abstract: 695,417. Pulse code modulation systems; pulse circuits. RADIO INDUSTRIE. June 12, 1951 [June 14, 1950], No. 13906/51. Classes 40 (v) and 40 (vi). Trains of code pulses, which can have only a single amplitude value, are deformed by passage through a low-pass filter, the output pulses being differentiated to produce double polarity signals for transmission over a channel of limited bandwidth and not needing D.C. component restoration. The pulse 12, Fig. 8, applied to filter 26, is converted to the rounded and broadened pulse 15 which is fed to valve 27. The differentiating circuit 28, 29 in the output circuit of the valve produces the double polarity pulse 18, 19 for transmission over the signalling channel. When an uninterrupted succession of pulses is applied to the circuit, all the resulting pulse elements cancel out except the first and the last. A circuit for restoring the original pulses at the receiver has two paths 32, 33, Fig. 9, containing oppositely-directed biased diodes 34, 37, respectively, which select and clip the positive and negative incoming pulse elements 18, 19, respectively. These pulses are applied to the two inputs 40, 41, of a bi-stable trigger circuit 42, so that an output pulse 47 is produced in lead 43, which is initiated by the first and terminated by the second of a pair of incoming pulse elements of opposite polarity. This pulse opens a gate valve 44 to pass locally generated pulses 48 from a source 45, timed to coincide with the original signal pulses 12 at the transmitter.

Title: Improvements in method of electrically welding together galvanized metal sheets, plates and other parts
IPC: B23K11/16
Filed: 1920-05-20
Abstract: 167,327. Ledwinka, J. May 20, 1920. Welding; welding joints; soldering; soldered joints.-Galvanized sheets, plates, strips, &c., such as terneplate, tinplate, or other steel plates &c. provided with a coating of softer metal such as lead, tin, zinc, bismuth, &c. are spot, butt, or lap welded electrically by first exposing the steel surfaces through the galvanizing or like material and then passing a current through the parts in the region of the exposed portions. The steel surfaces may be exposed by shearing off the edges of the parts. The zinc is volatilized by the current and serves as a flux. In spot welding, the zinc is volatilized at the welds but elsewhere spreads over and fills the welds and spaces between adjacent welds to produce a leak proof seam. In the form shown in Fig. 1, the edges 8, 9 are sheared and then overlapped and welded by electrodes 10, 11. In butt-welding, the sheared butted edges are lapped prior to welding by a strip sheared at its edges. A continuous lap weld may be effected by roll electrodes.

Filed: 1974-03-29
Abstract: 1426164 Crash bags FORD MOTOR CO Ltd 29 March 1974 [2 April 1973] 13944/74 Heading B7B [Also in Division H1] In a motor vehicle having electrical actuated means for causing the inflation of an inflatable safety device, first and second acceleration responsive switches 24, 26 are connected in parallel forward of the passenger compartment and these switches are connected in series with a third switch 140, the safety device being actuated by the first and third switches or by the second and third switches or by all three switches. In a preferred embodiment, Fig. 2, all three switches 24, 26, 140 are of the roller band type in which a conductive band, e.g. 80 moves into contact with an electrical pole 86 when a predetermined acceleration acts on the particular switch. The third switch 140 is responsive to a predetermined acceleration less than that to which the first and second switches 24, 26 respond. The switches 24, 26 are attached to the vehicle radiator 32 each having a mounting switch 48, 50 connected in series with it which indicate via a light 198 that the switches 24, 26 are properly secured to the radiator. A thermal cut-off switch 102 having a fusible element 122 with a coil of resistance wire 132 around it is used to disconnect the source of electrical energy 106 from the apparatus if either or both switches 24, 26, and not the third switch 140, are actuated for a predetermined length of time, say by inadvertent impact of the radiator when the vehicle is standing still. Illumination of light 198 indicates that capacitor 188 is being charged, that current is being supplied to mounting switches 48, 50 and to conductive bands 80, 80<SP>1</SP> of switches 24, 26, that switch 140 is conductive through band 148, and that thermal cut-off device 102 is -conductive between its terminals 116, 120. After capacitor 188 has become fully charged the light 198 is extinguished. Electrical actuation of squibs 160, 162 on vehicle collision causes a gas to be released and/or generated to inflate the safety device. In the event that the-electric source 106 should become disconnected or short circuited, then electrical energy to energize squibs 160, 162 is obtained from capacitor 188.

Title: Improvements in Wireless Electric Circuit Controlling Apparatus.
Inventor: INOUE MASANOBU
IPC: G08C17/00
Filed: 1916-10-03
Abstract: 106,266. Inoue, M. May 11, 1916, [Convention date]. Electric selectors.-Apparatus, such as propelling and steering motors of ships, automobiles, torpedoes, &c., is controlled selectively by wireless radiations, the selected circuits being completed by a switch, the position of which is determined by the pressure of gas generated electrolytically in a cell coupled through relay apparatus to the coherer circuit of the wireless receiving- apparatus. The coherer is placed in circuit with relay coils 21, 22, which, when energized, attract an armature 25 and cause an arm 30 to dip into a cup of mercury. A circuit is thus completed through the electrolytic cell 1, and the gas generated therein passes into a vessel 2 in which it is dried by strong sulphuric acid. The upper part of the vessel 2 has a tube 14 opening into the atmosphere through a constricted mouth, and a bent tube 11 communicating with a mercury switch 13, Fig. 2, which is in the form of a U- tube with one end open. The position of the mercury column 13 depends on the gas pressure in the vessel 2, which is determined by the rate of evolution of the gass in the cell 1. Regulation of the rate of gas evolution is obtained by varying, at the transmitter, the proportion between the periods of radiation and interruption. As shown in Fig. 2, the pressure in the vessel 2 is atmospheric and all the circuits controlled by the mercury are open. When the contact 18 is covered, the circuit of the propelling motor X is completed, and when contact 19 is reached, contact 17 still being covered, the first steering-motor Y is started. When the mercury reaches the upper contact 20, the contact 17 is uncovered, thus cutting out the motor Y and starting the second steering-motor Z. To prevent sparking in the presence of the gas, oil is floated over the pressure side of the mercury column. The mercury contact of the switch 31 prevents the cell circuit from being opened between the wave trains, when discontinuous damped waves are used.
