Title: Piezoelectric crystal apparatus
IPC: H03H9/19
Filed: 1942-03-28
Abstract: 552,355. Piezo-electric crystals. STANDARD TELEPHONES & CABLES, Ltd. March 28, 1942, No. 4159. Convention date, Nov. 16, 1940. [Classes 40 (iii) and 40 (v)] A rectangular piezo-electric quartz crystal 1 has two pairs of electrodes 2, 3 and 4, 5 which excite the crystal in two uncoupled modes, one being the fundamental longitudinal mode the frequency of which is mainly determined by the ratio w/d of which is dependent on the length d and the other being the second flexural mode the frequency width to length. To reduce the coupling of the two modes to a minimum, the crystal is cut with its major plane at right-angles to an X axis, and with the length and width dimensions at an angle to the Y and Z axes of either -19.5 degrees or +42 degrees. The length is first chosen to give the desired longitudinal frequency and then the width is chosen to give a w/d ratio suitable for the desired flexural frequency. The thickness t is then selected to give the required impedance. The percentage area of the crystal covered by the electrodes is then chosen. to give the correct value of the ratio of internal capacities of the two modes. This lies in the range 50 per cent-70 per cent. Fig. 9 shows a double resonance crystal 1 used in a band pass filter. The input terminals 22, 23 feed the network through inductances 26, 27 and the output is taken from 24, 25 through inductances 28, 29. Variable condensers 30 ... 33 are used to vary the characteristic. Specifications 437,294 and 542,452 are referred to.

Title: Damping device on a drawing trolley for a draw-bench for drawing tubes and bars
IPC: B21C1/28
Filed: 1968-01-29
Abstract: 1,208,631. Drawing. MANNESMANN-MEER A.G. 29 Jan., 1968 [28 Jan., 1967], No.4481/68. Heading B3P. A drawing trolley has a damping device which includes a plunger piston 25 lying against the rod or tube being drawn and energy storage means 19 for absorbing the energy suddenly released by the drawn rod or tube as it leaves the die. After the front end of the material to be drawn has engaged a contact plate 24 of the piston 25, jaws 12, 13 are closed to clamp the material. When the trailing end of the material has left the die and the jaws 12, 13 have been opened, the plunger piston 25 is pushed by the drawn material into a cylinder 23 to cause the hydraulic fluid such as oil to open a spring- biased damper 20 and to flow into a compartment 22 of the cylinder 23. A piston 40 is thereby moved in the pressure storage chamber 19 to compress the gas such as nitrogen therein causing the whole of the energy released by the drawn material to be absorbed until the latter comes to a standstill. The damper 20 is closed to prevent the material accelerating in the opposite direction and the material drops from the trolley. As the trolley remains stationary or returns to its initial position, the hydraulic fluid gradually flows from the compartment 22 through bores 39 in the damper 20 until the plunger piston 25 reaches its initial position. The compartment 22 and the chamber 19 are respectively connected to a storage chamber (59) (Fig. 2, not shown) and a storage tank (54) which serve to compensate for losses due to leaks.

Title: Artificial molar teeth and method of making the same
IPC: A61C13/00
Filed: 1926-02-17
Abstract: 249,089. Gysi, A. March 14, 1925, [Convention date]. Teeth, artificial.- The masticating surfaces of molar and bicuspid teeth consist of facets lying in a plurality of planes having three different inclinations and forming obtuse projecting and re-entrant corners. The lower teeth are provided with facets complementary to those of the upper teeth so that the surfaces coact to guide the jaw in its three main grinding movements. The position and shape of the various inclined facets of a complete set of back teeth, and thus of the various cusps and depressions of the individual teeth, are determined bv geometrical methods explained in the Specification. The elementary shape of the surfaces of an upper set of back teeth is produced on a block of plaster or wax mounted on the upper frame of an anatomical articulator, such as that described in Specification 10552/11, by means of a series of knives 16, Fig. 7, mounted on the lower frame in predetermined positions and each having a forwardly and upwardly inclined cutting edge terminating in a point 17. The plaster block 22, Fig. 12, is thus carved by the controlled relative movements of the parts of the articulator to the form shown on the right hand side of the Figure and is then trimmed by hand to the form of the teeth as shown on the left hand side. Minor depressions, fissures &c. are then formed on the surfaces bv hand, and the plaster models so obtained are used in moulding the porcelain teeth, which may be produced in blocks of four or two, or individually. The elementary model for the lower teeth is obtained by taking a plaster impression of the model of the upper teeth as cut in the articulator. Fig. 16 shows a model of a row of upper teeth with projecting corners 7 and re-entrant corners 8 formed by inclined surfaces 9, 10, 11, and Fig. 18 shows a corresponding finished second molar. The upper and lower teeth coact as shown in lingual elevation in Fig. 15. The lingual cusps 8<a> of the upper bicuspids Z, Y, Fig. 15, engage the masticating surfaces of the corresponding lower bicuspids Z<1>, Y', but the buccal cusps project into the interdental spaces as usual.
