Title: Improvements in or relating to Motor-cycle and like Driving-belts and the Process of Manufacturing the same.
Inventor: WARWICK GEORGE
IPC: B29D29/10
Filed: 1916-05-16
Abstract: 106,321. Warwick, G., and Crouch, A. P. May 16, 1916. Belts.-To form the canvas core of a rubberfaced motor-cycle driving-belt, a length of canvas is folded into a flat roll, Fig. 1, and this is passed between rollers to give it the cross-section shown in Fig. 4, the sides of the roll being pressed towards the upper face. The weftthreads on the underside of the core am by this means stretched and those on the upper side, which is flat or slightly concave, are slackened. This enables the belt to pass around a pulley with less strain on the threads of the canvas. One or more open coils of thread D are wound round the core A before it is covered with the rubber E.

Abstract: 798,974. Vibrating concrete. BAKKER, J. March 13, 1956, No. 7786/56. Class 87(2). The vibrating surface of apparatus for vibrating concrete or like material comprises a number of separate parts, such as I-section girders 1, which are resiliently mounted side by side on a supporting frame 5 and are vibrated by eccentric masses 8 arranged alternately in two parallel rows and driven at the same speed but in the opposite direction by two rows of spindles 7, 7a, so as to avoid giving to the concrete or the like a net lateral impulse in any direction. The eccentric masses 8 are mounted in casings 6 under the girders 1 and their spindles 7, 7a are connected by intermediate shafts 9 and flexible couplings 10. Thus each girder 1 is given a lateral impulse opposite to that given to the girder on either side of it. The masses may be arranged in groups of equal numbers each providing a vibrational frequency which is a multiple of the rotational frequency. If, e.g., an eight-fold vibration with respect to the fundamental rotation is required, each group of eight masses will consist of two sub-groups of four masses, one sub-group on each row of spindles, the four masses in each sub-group being mutually 90 degrees out of phase and 45 degrees out of phase with respect to the masses in the other sub-group. To prevent lateral impulses leading in one direction and lagging in the other direction, successive sub-groups on the same row of spindles are arranged mutually 45 degrees out of phase behind one another.
