Abstract: 467,994. Floors ; roofs ; girders. McALPINE, SIR M. Dec. 27, 1935, No. 35864. [Class 20 (iv)] A reinforced-concrete floor or roof comprises concrete cast in situ on a decking of pre-cast reinforced-concrete slabs c supported at their ends on landings b, which are provided on each side of main beams a below the upper face thereof and at such a distance from the centre of the beams as to provide spaces for the reception of the projecting ends of .the reinforcing bars d of the slabs c, the bars d being adapted to provide the principal reinforcement of the structure and the slabs being of sufficient strength only to support their own weight and that of the concrete e which is cast thereover to the thickness required to give the structure the required strength. The beams a may be of reinforced concrete, or of steel having side portions of concrete cast around the lower flange so as to form the landings b, as shown in Fig. 3. The beams a may be supported at the ends on walls g, each of which is provided below the level of the undersurface of the beams with a landing h to support the lower ends of slabs i disposed in inclined position with their upper ends resting against the side of the adjacent deck slab c. The reinforcement of the slabs i also projects into the concrete e. The space beneath each beam a, adjacent a wall g, is filled with a slab k which coacts with the adjacent slabs i. The projecting reinforcement d of the slabs c is anchored in position by stirrup bars n projecting from the concrete of the main beams a.

Title: Improvements in or relating to supersonic testing apparatus
IPC: G01N29/04
Filed: 1946-12-10
Abstract: 643,146. Supersonic inspection devices. SPERRY PRODUCTS, Inc. Dec. 10, 1946, No. 36423. Convention date, Dec. 19, 1945. [Class 118 (ii)] In a method of supersonic testing, a fundamental frequency is generated which is strong in harmonics and transmitted to the test object through a piezo-electric crystal having a natural frequency which either corresponds to or is a harmonic of the said fundamental frequency, and thereafter the piezo-electric crystal is substituted by another such crystal having a different natural frequency which is also either the fundamental frequency or a harmonic thereof. Providing these specified crystals are used, the oscillator circuit of the apparatus can be fixed. As shown, the pulse impressed on a crystal 11 in engagement with an object 12 is also impressed on an amplifier 15 associated with an oscilloscope 16. The pulse generator comprises an oscillator 30 having a control grid 31 on which is placed a relatively large negative bias by a trigger valve 32. A square wave generator 40 feeds through an amplifier 34 and inverter 35 to bias the grid 33 of the trigger valve 32 sufficiently to render the latter non-conducting, thus reducing the negative bias on the grid 31 of the oscillator 30 to allow the production of the desired pulse. The duration of the pulse is a function of the square wave which can be adjusted by potentiometer 37. The oscillator includes a tuned circuit having a coil 45 and a condenser 46 which is fixed at the frequency of the crystal having the lowest frequency in a set to be employed in testing. The characteristics of the oscillator circuit are chosen to yield the maximum number of harmonic frequencies. Specifications 637,164, [Group XL (c)], and 641,095 are referred to.
