Abstract: 455,549. Book - supports. TERAG TELEPHON - REKLAME AKT.-GES., 17, Morgartenstrasse, and GRABER, G., 28, Hirschmattstrasse, both in Lucerne, Switzerland. March 7, 1936, No. 6930. [Class 16] A holder for securing telephone and other reference books, of the kind having means for clamping the book in position so that the book can be turned through an angle of 180‹ into position for use, comprises a screw spindle arranged longitudinally of the holder and associated with a mechanism allowing co-operating pairs of jaws, which grip the book at the back, to be simultaneously operated by means of the spindle. Several holders are pivotally mounted on a central transverse rod in a desk or the like whereby each book can be independently turned about the rod and opened out on the desk for use. In the form shown in Fig. 4, the holder 1 has a single longitudinal spindle 8 with right and left hand screw-threads, and two pairs of jaws 11 are adapted to be operated on rotation of the spindle by the engagement of the studs 11b on the jaws with oblique grooves 9a in slides 9 connected to the spindle. In a further form shown in Fig. 10, the holder has a longitudinal spindle 26 with right and left hand screw-threads for operating two nuts 27 which have studs 28 passing through longitudinal slots in three superposed elongated plates. The bottom plate is fixed to the cover plate of the holder and its slot is arranged parallel to the spindle 26, but the upper plates 31, 32 are loosely mounted between the bottom plate and the nuts and are arranged to cross each other. The plates 31, 32 have the gripping-jaws 37 pivotally mounted at their extremities, and when the spindle 26 is rotated, the studs 28 travel along the slots in the three plates whereby the plates 31, 32 are moved to operate the jaws. The cover plate of the holder has transverse slots in which the jaws 37 are guided. The operating spindle may move the jaws through toggle links, and only one jaw of a pair may be movable. For preventing a heavy book from dropping when released from the jaws; coil springs which pass through transverse apertures in the back of the book are secured to the co-operating jaws. Specification 434,922 is referred to.

[Also in Division F2] To facilitate engagement of male and female coupling elements 8, 12 forming a splined coupling between a power take-off shaft 6 of a tractor or truck, and a universally jointed driven shaft, the ends of the internal splines 14 in the female element 12 are swaged and compacted to form convergent tapering surfaces 16 such that when the element 12 is moved axially to engage the male element 8, the surfaces 16 contact the ends of the male splines 10 and exert a camming thrust indicating the direction requiring the minimum relative turning of the coupling elements to effect full spline engagement of the coupling. The ends 16 of the splines 14 in the female element 12 are swaged concurrently and the splines subsequently broached to remove any malformation resulting therefrom.

Abstract: 1374503 Aircraft acceleration indicators R J HANSEN 11 Oct 1972 [7 Feb 1972] 46948/72 Headings G1J G1K and G1N An aircraft take-off abort indicator 10 comprises an accelerometer 42, such as a pendulum (44), mounted in the aircraft and coupled to a pointer 50 movable radially of a circular chart 32 in response to the output of the accelerometer 42, the chart 32 being rotatably driven at constant speed beneath the pointer 50 by an electric motor 22 such that, if the pointer 50 should encroach on an area 38 of the chart, thus indicating that the acceleration of the aircraft is too low in take-off, an alarm is initiated to warn the pilot. The area 38 between lines 34 and 36 is conductive and completes a circuit between contacts (56) on the pointer 50 when the pointer is within the area 38 thus operating a buzzer or indicator lamp 58. The line 34 defining area 38 is positioned on the chart according to the normal take-off acceleration of the aircraft with time. Different charts may be used according to parameters such as the aircraft weight, wind speed, barometric pressure and runway conditions. An extended conductive region 40 on the chart may be provided to warn the pilot that take-off should be aborted on the basis of time alone. If the accelerometer 42 is responsive to deceleration then the indicator 10 can be used with an appropriate chart as a landing abort indicator. Instead of a pendulum (44), the accelerometer may, as in Fig. 5, comprise an inertial mass 62 acting on a pressure sensitive resistor 64 determining the energization of a solenoid 70.
