Patent DE-2618863-A1 (DE)
Inventor: MOYER NORMAN E
IPC: G04G99/00
Filed: 1976-04-29
Abstract: A digital watch with oscillator/divider power selection circuitry. The selection circuitry selects the source of the voltage to be supplied to the crystal oscillator and initial divider circuits. If battery voltage is low because battery current is high, as when the light emitting diodes (LED's) are illuminated in an LED digital watch or when the illumination light is on in a liquid crystal display (LCD) digital watch, the crystal oscillator and initial divider would be powered by two batteries; and when battery voltage is high because battery current is low, the crystal oscillator would be powered by only one battery. Therefore, the power selection circuitry determines whether one or two batteries are used to power the oscillator depending upon the particular operating conditions. There are two advantages of this technique: (1) current is reduced so battery life is increased, and (2) the voltage never goes so low that circuit production yields are adversely affected.

Title: Projectile-stopping composite material - contg. steel plates, polyamide 12 layers and aramid fibre layers
Inventor: HAUPT GUENTER ING GRAD
IPC: F41H5/04
Filed: 1976-09-23
Abstract: In parent patent projectile-stopping composite material contains a steel plate coated on one or both sides with polyamide 12 (obtd. by anionic polymerisation with use of monomeric lauric lactam). In this addn. the effectiveness of this material is enhanced by applying onto the free side of the polyamide 12 layer several layers of aramid fibre web ('Kevlar'; RTM), topped by another polyamide 12 layer. Opt. several layers of aramid fibres (pref. 5-15 webs in each layer) and several polyamide 12 layers can be applied in alternating order. The aramid fibre webs are pref. impregnated and/or densely woven. One or two hard steel plates can be used. Polyamide 12 and aramid fibres have high resistance against deformation. Therefore, they effectively brake the projectile and convert its energy into heat which is absorbed by the polymers when they eventually melt. The combination of polyamide 12 and aramid fibres gives a synergistic effect. Polyamide 12 dams the mechanical vibrations produced by the impact of a projectile.

Title: Perforated self-adhesive film - bearing painted or printed sewing pattern for adhesion to fabric
IPC: A41H3/06
Filed: 1976-10-30
Abstract: Perforated self-adhesive film can be painted or printed with sewing patterns which can be adhered to fabrics and cut out together with the fabrics. Marking lines and dots can be applied to the fabric with tailor's chalk. The film and the release paper pref. consist of transparent material, and the film coating has properties which prevent it from adhering to the fabric or leaving behind residues. To transfer the marking lines or dots to the fabrics, the tailor's chalk is simply run over the preprinted or prepainted lines, and the perforated points allow transfer of the chalk. The pattern can thus be fixed to the fabric easily and without creasing, and without the difficulty and risk of pricking when trying on fabric pieces to which the pattern is fixed with pins.
