Title: Improvements in apparatus for training bomb aimers
Filed: 1941-09-06
Abstract: 551,762. Bomb-aiming trainers. GLENNY, A. P., and SPERRY GYROSCOPE CO., Ltd. Sept. 6, 1941, No. 11397. [Class 119] A bomb-aiming trainer comprises a target movable toward a turnable sighting device, the target carrier and sighting device being both transversely adjustable to each other to simulate side-wind driftage and correction for the same. The target 1 is moved towards a turnable sighting device 7 by a motor 7, 2 the target carrier and the sighting device being mounted on a common axis 4 about which each can rotate independently to give the effect of side-wind driftage. The target carrier is moved transversely by a motor 6 the circuit of which is controlled by a Wheatstone Bridge 22, 23 and movable contacts 31, 24, the one contact 24 being moved by the instructor to disturb the bridge and cause lateral movement of the target while the other is adjusted through screw-gearing of a continuously rotating power member 19 from a hand control 10 under the operation of the pupil to reduce the speed of the traverse at the same time as the sighting device is also rotated by a continuously rotating power unit 12 and controlled by the pupil to counteract the lateral drift. In a modification the contact 21 and the rotation of the sighting device are operated by a single power unit under the control of the pupil.

IPC: H01B13/10
Abstract: 114,872. Beaver, C. J., and Claremont, E. A. April 3, 1917. Cables and compound conductors. - Two-core electric cables are built up from three strips of rubber or other flexible insulating material which are pressed together so that the edges of the strips adhere and become autogenous. The circular or approximately circular cable thus formed is then vulcanized. Fig. 1 shows a machine having two pairs of grooved rollers e, e<1> and e<2>, e<3> for applying the insulating material in two stages. Fig. 4 shows, in a broken section on the line c-c of Fig. 1, the completed cable leaving the rollers. The central insulating strip a and the conductors b, b<1> are accurately disposed by a guide d before passing between the first pair of rollers. In the second pair of rollers, the outer strips c, c<1> are pressed on to the central strip, the outer edges being bitten by the shoulders k<2>, k<3> and the surplus width received by the grooves l<2>, l<3>. The whole operation may be performed by a single pair of rollers or a number of cables may be simultaneously produced by the same pair of rollers.

Abstract: 1,264,176. Deaf aids. E. BIONDI, and L. BIONDI. 5 March, 1969 [29 March, 1968], No. 11583/69. Heading H4J. Voice frequency sound signals are made audible and comprehensible to profoundly deaf persons by transforming the voice frequency sound signals in a low frequency range into a corresponding electrical information signal. A second electrical signal having a frequency higher than that of the information signal, of constant or slightly varying repetition rate up to 5 kHz, is added to the electrical information signal and the sum electrical signal is converted into a corresponding sound signal. Preferably the sum signal is amplified before being converted into the sound signal. Apparatus is described comprising an integrated circuit astable multivibrator (1), Fig. 4 (not shown), and an input microphone (2). Their outputs are added and, after amplification in a singleended transistor amplifier (4), the output is applied to a transducer (5) providing sound signals. The second electrical signal stimulates the synapsis-neuron of the severely deaf person to enable him to hear the voice frequency sound signals.

Abstract: 1312600 Lasers WESTERN ELECTRIC CO Inc 16 March 1972 [19 March 1971] 12245/72 Heading H1C A laser resonator comprises a convex mirror, a lens and a concave mirror, the active medium being between the lens and the convex mirror, the focal length f of the lens and the separation p between the lens and the concave mirror being such that f<p. In Fig. 3 the convex mirror 30 and the lens 31 are formed on a solid laser rod 35 which is optically pumped, and the dotted line 36 represents the profile of the TEM oo  mode. The resonator allows efficient and stable operation in this mode with a relatively short mirror separation, the overall length in practice being determined by the difficulty of making the mirrors and by the high intensity of the light incident on mirror 32 for a short resonator. The beam has a waist portion where a modulator or non-linear element 39 may conveniently be placed. For the purposes of analysis only, mirror 32 may be replaced by its image at the other side of mirror 30, as in Fig. 4 (not shown), which allows the resonator properties to be calculated as for a conventional lensless cavity.
