Patent DE-2516307-A1 (DE)
Title: Quartz crystal oscillator element - has high frequency stability over whole of life span
Inventor: SCHMITT PETER DIPL PHYS
IPC: H03H9/19
Filed: 1975-04-15
Abstract: A simple quartz crystal oscillator element is designed so that high resonance frequency stability over its life-span is achieved. The final stable frequency of the element is achieved sooner than for traditional elements, and that frequency is maintained accurately for the remainder of its life. In its simplest form the element comprises a small thin disc (1) of quartz with a slightly thicker section (2) at the centre of the disc. Two electrodes (3), one above and one below the disc, and arranged diametrically opposite to each other, run across the element over extended radii. The configuration of energy when the element oscillates is described. A number of similar, alternative forms of element construction are also described.
Patent DE-2516681-A1 (DE)
Title: Remote control system with central and further stations - can have additional station evaluating signal exchange between central and further stations
Inventor: HERKERT HANS DIPL ING
IPC: H04Q9/14
Filed: 1975-04-16
Abstract: The central and several further stations arte identified by addresses and they are connected with a common transmission network. An evaluation circuit in the central or evaluating station delivers a signal in addition to the coded address of the station called by the central station, or of an answering station, at a first output when the central station is sending, at a first second output when a station replies. A store for new signals follows an intermediate store and stores the operational states of the stations. An intermediate store temporarily stores signals delivered through the evaluating device output, and either erases this signal if it is immediately followed by a signal at the output, or retains it if it is immediately followed by a signal at the output, and delivers it to the store as a signal for the corresponding station failure.

Title: Detector for telephone subscriber line states - is determined by different levels of loop current applied to evaluation device
Inventor: REINICKE JOCHEN ING GRAD
IPC: H04M3/22
Filed: 1975-05-10
Abstract: The telephone subscriber line state detector incorporates a loop circuit with a resistor provided in the loop. The voltage drop across it is applied to a comparator to which a number of reference voltages are applied, corresponding to that of current levels different from zero to be detected. A device superposes on the reference voltage a voltage corresponding to a voltage drop caused by external currents. A similar loop includes a larger resistor connected to the other terminal of the dc voltage source. Each loop line is coupled through a capacitor to a differential amplifier, the outputs from which are fed to an AND gate forming part of a logic circuit with OR gates.

Title: Automatic vending machine non-jamming coin magazine - is spring mounted to move laterally to and fro when purchase is made to distribute coins evenly
Inventor: STIEGLER ALOIS
IPC: G07F9/06
Filed: 1976-06-04
Abstract: An automatic vending machine magazine has an antijamming device such that the coins entering it from the coin mechanism do not form a pile which can eventually jam the mechanism. The machine capacity for coins is thus enhanced without a corresponding increase in size. A coin magazine box (2) is situated below the goods dispenser (10) on the floor of the machine outer casing (1) and directly below a coin channel (4) leading from a coin inspection mechanism (5). The magazine is spring mounted (21) so that it can move sideways under the action of a sprung lever (15) when a purchase is made and this operates a pyramid of coins forming in the magazine.

Title: Soluble base oils for lubricant emulsions - made by sulphonation of naphthenic oils and neutralisation with amines
Inventor: IVEY JUN HERBERT D
IPC: C10M169/00
Filed: 1976-06-08
Abstract: Compsns. consist of a low mol.wt. mineral oil contg. 0.5-10% sulphonate, made by treating a straight-run naphthenic Western mineral oil with distn. range 260-600 degrees C, and V.I. 50, with 0.1-10 wt.% H2SO4. After removing sludge from the prod., it is neutralised with an organic amine. The mixts. contain 5% refined Na sulphonate or other surfactant. Used in prodn. of stable oil-in-water or water-in-oil emulsions for machine lubrication, etc. The mixts. are readily emulsified, although the content of refined sulphonate emulsifier is reduced e.g. from 20% to below 5%. The sulphonate formed in the oil remains sufficiently hydrophobic to prevent pptn. In an example, a naphthenic oil with distn. range 260-340 degrees C is stirred with 110 vols. conc. H2SO4 at room temp. for 1.5 h. and settled for 4 h. 1% monoethanolamine is added to give pH 8, after removing the deposit, giving a stable oil contg. 2.5% sulphonate. This forms stable emulsions with water.
