Title: Improvements relating to the joining of frame members of structures
IPC: E04B1/24
Filed: 1945-04-23
Abstract: 592,284. Structural framework joints. BEADLE, Ltd., J. C., HICKS, H. G., and IRLAM, P. R. April 23, 1945, No. 10134. [Class 20 (ii)] [Also in Group XXXII] Relates to the joining of frame members of structures, such as the frame members of a vehicle body or of a building, and resides in a method of joining together in the same plane two or more frame members 1, 2 each having two channel portions disposed base to base to form an H-section, the method consisting in interposing between the opposed channel bases of each member a gusset plate 5 which occupies the entire area of intersection bounded by the sides of one member 2 and imaginary continuations of the sides of the other members 1 and which includes a web portion which spans the angle between the connected members, and securing said gusset plate to said channel bases. In the example shown, each frame member is fabricated from two channel bases 3 having their bases bonded together by welding, brazing or otherwise, except where they are separated in the region of the joint for the reception of the gusset plate 5. The side plates 4 are bonded to the sides of the channel members, and are slotted as at 6 to allow the gusset plate 5 to pass through them. The gusset plate 5 may be welded to the crossing member 2 before assembly, the protruding portion of the plate subsequently being riveted to the members 1, 1. Rivet holes may be previously formed in the protruding portions of the gusset plates and in the channel bases of the frame members to which they are to be secured, the holes being positioned to coincide when the frame members are in their properly related positions. The invention is applicable to a joint of X form with the members crossing at any angle, to a T-joint and to a simple angle joint. The invention is also applicable to frame members drawn from metal tubing to have the cross-sectional form of a letter H having double flanges and a double web, the gusset plate being received in the hollow space in the web; and the invention applies to solid frame members of H-section slotted right through from side to side, the slot passing centrally through the thickness of the web. Framework units may be built up by joining frame members according to the invention, with portions of the gusset plates protruding for connection to other such units. The H-section members can be filled with wood or other fibrous material 11 for use as a base for fixing a cover.

Title: Frequency and phase control system
IPC: H03L7/06
Filed: 1947-04-17
Abstract: 637,243. Automatic control systems. BENDIX AVIATION CORPORATION. April 17, 1947, No. 10283. Convention date, May 28, 1946. [Class 38 (iv)] In a system for maintaining a controlled oscillatory source 26 in frequency agreement with a controlling source 10, and with zero or predetermined phase difference, the controlling source is coupled to a circuit including an electronic gating means 36 and a storage condenser 56, the gate being opened by pulses derived at 30 from the output of the controlled source 26, and the condenser voltage being used as a frequency control voltage for the source 26. The source 10 is coupled by a transformer 11 to a circuit including the gate 36, condenser 56 and resistor 54. The gate 36 comprises two oppositely-disposed triodes with both grids 34 connected to the output of the pulse generator 30. The condenser 56 is in the grid circuit of a cathode follower valve 22, the cathode voltage of which follows the grid voltage and is used to adjust the frequency of the source 26. In Fig. 2, curve a shows the secondary voltage of the transformer 11 and curve b the pulse output from 30 when that output is lagging. The pulses on the triode grids thus occur when the voltage a is positive, and a positive charge passes through the right-hand triode to render the grid of the valve 22 more positive. The. consequent increase of voltage on the cathode tends to increase the frequency of the source 26 and brings the pulses to the position d, Fig. 2, at which they fail to open either gate valve 36. If the pulses are leading, -curve c, a negative charge passes to the condenser 56, and the opposite effect is produced. A predetermined phase relation between the two oscillators may be secured by interposing a phase-shift network in the output of either oscillator. The controlled oscillator may operate at a sub-multiple of the controlling oscillator frequency.

Abstract: 1,000,132. Electric selective signalling. COMPUDYNE CORPORATION. March 20, 1962 [Sept. 20, 1961], No. 10583/62. Heading G4H. An apparatus for converting an analogue voltage to a pulse frequency comprises an integrator which feeds a threshold device, the output of the device operating a counter and providing feed-back signals to the integrator. As applied to an apparatus for measuring the total weight conveyed or the average rate of flow of material on a conveyer 1, Fig. 1, a load cell 3 is used to derive the instantaneous rate of flow by means of a weighing device 4 and tacho-generator 2. The resultant signal E 1  is passed to an integrating unit comprising amplifier 12, Fig. 2, and capacitor C 1 . The output E 3  of this unit is passed to a threshold unit 20 which gives a pulse of predetermined width when the threshold is reached. The pulse is fed to a counter and also, via a clipping circuit 19, as a feed-back circuit to the integrator. Fig. 3 shows the output of the integrator. E 5  is the threshold level, and the feed-back pulse discharges C 1  during time T 1  prior to the next integrating action. If the threshold unit includes gate 14 this gate may be fed with clock pulses from unit 15. Alternatively, the tachogenerator 2 may deliver A.C. pulses, of repetition frequency dependent upon the conveyer speed, to gate 14. In this case the load cell has a reference voltage for its second input, Unit 16 may be a mono-stable or bi-stable trigger. Specification 738,353 is referred to.
