Abstract: 417,941. Walls ; floors ; roofs ; metal slabs. SUTHERLAND, H. W., 17, Alfred Street, Islington, London. April 12, 1933, Nos. 10922 and 23684. [Classes 20 (i), 20 (iv), and 87 (i).] Walls of temporary or permanent buildings are constructed of shallow tray-like sheet-metal panels 1, which are assembled with the interposition of packing strips 5 between adjacent flanges 2, and are connected together by fastening means 4, such as bolts or rivets passing through the flanges and packing strips. The packing strips may be composed of rubber, felt, or the like. Some or all of the flanges may be turned inwardly at their edges to form ledges against which an inner wall may be pinned. Bars 6 of H-cross-section may be permanently or removably secured across the longitudinal flanges 2, as shown in Fig. 7, to strengthen the panels. Alternatively, the strengthening bars may be of angle form and have slit end portions which are bent inwardly and overlapped as shown at 8, 9, Fig. 8, or one slit portion may be bent inwardly and the other portion outwardly, as shown at 11, 12, Fig. 8 ; apertures 10 in the bent portions enable the bars to be bolted or riveted to the flanges 2. The end portions of the strengthening bars may also be cut to a triangular form and bent as shown at 13, Fig. 8, the opening 14 between these parts being adapted to receive the securing bolt or rivet. The strengthening bar may, alternatively, be of tubular or channel section and be block-ended or provided with a turned-over part 15, Fig. 8, and a screwed stud 16 for securing the bar to the flange 2 may be mounted on either the part 15 or a wooden fillet 17. The panels may also be stiffened by corrugated sheet metal 18, Fig. 9, which may be either welded in position, held by turning over the edges of the flanges 2, or detachably mounted by apertured lugs 20 bolted to the flanges 2. The panel edges may be stiffened by strips 31, Fig. 11, held between the doublefolded flanges 2. The corners of the panels may be of mitred or overlapped form and may be additionally reinforced by fitting shaped corner strips in the double-folded flanges. Suitable jointing members 1b of angle or other section are employed, as shown in Fig. 3, where adjacent panels are arranged at an angle to each other. Inclined roof panels 27, Fig. 1, are secured to the wall panels 1 by flanged strips or plates 25 which are bolted to the flanges of the roof and wall panels. Weather strips 28a are mounted above the upper flanges of the wall panels and are pressed against the roof panels. The roof panels 27 are bolted to a channelled ridge member 28 which may support a capping strip 30. Floor panels 1, Fig. 4, are supported by joists 34 of T-section. The first Provisional Specification describes also the packing strips as formed of hard wood or tarred felt. Reference has been directed by the Comptroller to Specifications 243,917 and 321,325, [both in Class 20 (iv).]

Patent GB-706037-A (GB)
Title: Improvements in chain stretching and testing machines
Inventor: STEINKRAUS HERMAN
IPC: G01M13/02
Filed: 1951-05-11
Abstract: 706,037. Testing physical qualities of chains. ESSER, P., [trading as MEYER, ROTH & PASTOR, MASCHINENFABRIK]. May 11, 1951, No. 11146/51. Class 106 (2). [Also in Group XXII] A chain testing, stretching and marking machine through which the chain is fed step by step has means automatically operated by and controlled from a main driving shaft for feeding, testing stretching and marking lengths of the chain. A motor driven flywheel 2 turns the main driving shaft 5 through pinions 3 and 4. On the shaft 5 is a crank disc 31 coupled to a connecting rod 32 in a manner giving it an adjustable stroke of from zero to ninety millimetres. The connecting rod 32 imparts its stroke to a pivoted lever 34 through an adjustment nut 33 and the resulting reciprocating motion of the free end of the lever 34 moves a carriage 37 on the testing machine. The carriage 37 has means whereby on its forward stroke, as indicated by the arrow, the chain is gripped and moved forward with the carriage but such that on its return stroke the chain is released from the said gripping means. In this manner, lengths of the chain are continually fed forward step by step. The main driving shaft 5 is also continually coupled to two longitudinally extending shafts 12 arranged one on each side of the testing machine. The two shafts 12 each have means whereby after the chain has been fed forward, opposed tension jaws 18 on a fixed tension head 17 and opposed tension jaws 18<SP>1</SP> on a movable tension head 16 are caused to close on and grip the chain, whereafter the movable tension head 16 is given a predetermined longitudinal movement through a bell crank lever 14 operated by a cam action from the main driving shaft 5. The said movement stretches the chain links between the heads 16 and 17 to the required length. At the end of the stretching stroke the jaws are automatically caused to release their grip on the chain and the movable head 16 is returned to its starting position. The stationary head 17 is connected to one end of a cylinder 26 slidable in a fixed bearing 27, the cylinder 26 having at its other end a nut 29 and a pressure indicator 28 between the nut 29 and the bearing 27. The tension set up in the chain during the stretching stroke is thus transmitted to the pressure indicator 28 and should, by reason of a fault or by reason of an unduly stretched chain, a predetermined pressure not be attained, then by known electrical means, for example, a bell warning is given or the machine is automatically stopped, so that the faulty chain link can be removed. Instead of, or adjacent to the scale of the pressure indicator 28, a recording device may be provided that shows the result of each test. The machine includes a mark stamping device 42, operated from the main driving shaft 5, which, after each satisfactory test automatically marks a link of the chain length tested.

Title: Improvements in folding laryngoscope and angularly adjustable and detachable joint therefor
IPC: A61B1/267
Filed: 1951-05-15
Abstract: 685,741. Surgical optical instruments. WELCH ALLYN, Inc. May 15, 1951 [Feb. 12, 1951], No. 11314/51. Class 81 (ii). A laryngoscope comprises a handle and a blade interconnected by a hinge joint including complemental relatively rotatable members for enabling the blade to be angularly adjusted relative to the handle, shiftable means for locking the handle and blade in selected adjusted positions and means for releasably preventing the shiftable means from being shifted in one direction. A blade 2 carried by head member 4 is connected to a handle 1 by a hinge joint 3. The hinge joint 3 comprises a member 6' integral with a base portion 6 of the handle 1 and having a portion 14 which receives a complementary member 5 integral with the head member 4 of the blade 2, the two members 5, 6' being held together by pins 9<SP>1</SP> arranged in slots in such a way that the complementary members may only be separated on rotation when in one particular relative position. A plunger 17 attached to a button 24 is fitted with splines 18 which slidably engage splines 16 on the member 6' attached to the base 6 and splines 18 which engage splines on the member 5 integral with the head member 4. The plunger 17 is normally held by a spring 27 so that the two sets of splines engage to lock the members 5, 6<SP>1</SP> relative to one another and hold the blade 2 and handle 1 in any desired relative position. When the plunger 17 is pressed inwardly by the button 24 the splines 18 are disengaged from the splines on the member 5 integral with the head member 4 and are replaced by a narrowing 19 of the plunger 17 so that relative rotation of the members 5, 6<SP>1</SP> is allowed and readjustment of the blade 2 and handle may be effected. The skirt of the button 24 is provided with a segmental recess 30 in the region of the base member 6 to allow depression of the button 24. Inadvertent depression of the button 24 is prevented by a cam lock 31 or in an alternative construction (not shown) by rotation of the button 24 so that its segmental recess 30 is displaced from the region of the base member 6. A lamp 35 mounted on the blade 2 is illuminated for at least one blade position in which a conducting ball (not shown) mounted in the head member 4 is in contact with a conducting strip (not shown) which is surrounded by insulating material 44 on the surface of the hinge member 6' which is integral with the base member 6, the conducting strip being connected with a battery 36 in the handle 1 or a mains supply.

Abstract: 346,568. Electric clocks. VOLKERS, E., 27, Corneliusstrasse, Lankwitz, Berlin. April 9, 1930, No. 11319. Convention date, Oct. 22, 1929. [Class 139.] In a time-piece balance 1 operated electrically from the end of its spiral spring, this end is secured to a control lever 6 which alternately releases an operating member 7, which re-energizes the balance electrically, or thrusts against a stop 13. This stop may be on the clock frame or on the member 7. The balance 1 and its spring are between bridges 2, 3 and the re-energizing mechanism is between bridges 3, 4. The end of the spiral is attached at 5 to the lever 6 which is loosely mounted on a pivot. Rigid with this pivot is the operating member 7, carrying a locking spring 9, which coacts with a stop 10, and a contact 14. As the balance swings in the direction of the arrow, Fig. 3, it carries lever 6 with it so that a pin 11 on this lever releases spring 9, Fig. 4, lever 7 is swung counterclockwise, Figs. 3 and 4, by its spring 8 and closes contacts 14, 16 of magnet 15, the armature of which thereupon returns lever 7 clockwise, re-energizing the balance and breaking the circuit. The pivot of lever 6 is coaxial with the balance staff. A stop 13 on the frameplate limits the swing of lever 6. In modifications (1) the levers 6, 7 are on pivots which are not coaxial and (2) the pin 13 is carried on member 7.

Abstract: 984,423. Transistor sawtooth generating circuits. MARCONI CO. Ltd. Sept. 27, 1961 [March 28, 1961], No. 11328/61. Heading H3T. In a free-running time base comprising a capacitor 6 which is periodically charged through a resistor 5 and discharged through a transistor T1, and in which feedback from the primary of the output transformer to the base of the transistor T1 is employed to make transistor T1 conductive at the end of each sweep if negative synchronizing pulses applied at terminal 1 fail, a bias voltage dependent upon the current flowing through the output transistor is fed back to the base of transistor T1 to cause the transistor T1 to become conductive to discharge the capacitor 6 before saturation occurs in transistor T4 or any of transistors T2, T3, T4 are overloaded. Immediately following a synchronizing pulse at terminal 1 or an equivalent pulse fed back from transistor T4, capacitor 6 commences charging negatively, the linearly increasing voltage thereacross being amplified by transistors T2, T3, T4 to produce a sawtooth waveform at the output for application to the deflection coils of a cathode-ray tube. The current through transistor T4 increases linearly, so producing a negative-going waveform at its emitter, a fraction of which is applied through resistor 14 to the base of transistor T1 which remains non-conducting until the voltage applied to its base exceeds a cut off threshold for the transistor. When this happens and transistor T1 commences conducting, the rate of increase of current through transistor T4 decreases and by regenerative action a negative pulse is produced in the collector circuit of transistor T4 and fed back to the base of transistor T1 to render transistor T1 fully conducting to discharge capacitor 6. Linearizing feedback is applied from the secondary winding of the output transformer by means of capacitor 7 and resistor 8 to the emitter of transistor T2. Capacitor 7 may alternatively be returned to earth and the feedback from resistor 8 applied to the lower electrode of capacitor 6, thus effectively providing a Miller connection for the capacitor 6, Fig. 5 (not shown).
