Title: Low fat content minced meat - produced from bone meat by water dilution and gentle three-stage heating
Inventor: SCHMITZ WERNER
IPC: A23L13/60
Filed: 1973-09-11
Abstract: Meat with a low fat content, suitable for consumption as minced meat, can be prepared from meat scraped off fresh bones by mixing it with water in a proportion of 2 : 1 and by heating it in three stages to max. 65 degrees C. The suspension is decanted and the fat content is adjusted to 10-12%. The final product is dried to a residual moisture content of 50%.

No chemicals or other admixtures reduce the nutritive value.
Patent DE-2346676-A1 (DE)
Title: Teaching machine presentation of educational programmes - uses 8mm and 16mm films and optical signalling arrangement
Inventor: GUHL HANS
IPC: G09B7/06
Filed: 1973-09-17

Title: Combined lock for camera back and film spool hub - has a lock bar coupled to a two position flush mounted control button
Inventor: SEMENOWNA SERB ANTONINA
IPC: G03B19/04

Title: Sheet metal workpiece holder for stamping-presses - permits limited vertical movement of sheet during stamping
Inventor: TAYLOR VICTOR E
IPC: B21D28/26
Filed: 1974-09-16
Abstract: Workpiece holder for machine tools using a cross-slide to hold the piece. First and second arms are connected between their ends by a pivot and one end (I) of one arm is fixed on the cross-slide; the other ends of both arms are provided with jaws for clamping the workpiece and a pneumatic device swings the arms on the pivot to operate the jaws; and a flexure device is located between the pivot and (I) so that the arms can move in the same plane as the pivot motion. The flexure device is pref. an integral part of one arm, flexure being achieved by a reduced cross-section. The workpiece is securely held in the two horizontal (x and y) directions but the clamp intentionally lacks rigidity in the vertical direction so the sheet metal can move up and down during stamping, e.g. up to the stripper-plate.

Title: Fluorine-contg. substances for dental purposes - comprising a solution of a fluorine cpd. in a deuterium-enriched solvent
Inventor: NATH GUENTHER DR
IPC: A61Q11/00
Filed: 1974-10-10
Abstract: Fluorine-contg. substances, esp. for use in dentistry consists of a fluorine-contg. cpd. (pref. DF, LiF, NaF, KF RbF, CsF, SrF2, BaF2, ZnF2, SnF2, SnF4, NH3F or ND3F) dissolved in a solvent the H-content of which is substd. to an extent of at least 10% by deuterium. A pref. solvent is water contg. is not 10% D2O. When the substances are applied to the surface of the teeth and subjected to the action of infrared radiation, the incorporation into the dental enamel is promoted. Since the fundamental vibration frequency of the OH gps. of hydroxyapatite is 3.1 mu and that of the OD gps. in the solvent is 4 mu, IR radiation of wavelength 3.1 mu which promotes incorporation of F into the hydroxyalpetite of the dental enamel is only weakly absorbed by the solvent and incorporated of fluorine is better than with deuterium-free solvents.

Title: Pivoted plough in front of armoured vehicle - is lowered at full speed travel for excavating protection embankment
Inventor: PUESCHEL HARTMUT
IPC: B62D49/04
Filed: 1974-10-31
Abstract: The plough mounted in front of an armoured vehicle digs the armoured vehicle rapidly into the ground for assisting the crew on entering and leaving the armoured vehicle through the door in the vehicle hull bottom and it protects the armoured vehicle against the anti-tank weapons. Then the plough also acts as front protection shield, being supported by a hydraulic actuator on the vehicle hull. It can be lowered from the armoured vehicle, even if it travels at full speed. The armoured vehicle is brought to standstill, while an appreciable quantity of soil is being excavated. This arrangement produces rapidly a front and side protection embankments for the vehicle.

Title: Appetite stimulation by galvanic current in mouth - operating by stimulating salivary glands to secrete saliva
Inventor: TUCHENHAGEN OTTO
IPC: A61N1/20
Filed: 1975-07-15
Abstract: Method of stimulating the appetite is carried out by placing metal plates or electrodes of different potential in the mouth of the patient, and adding alkaline or acid media to generate an effective galvanic current which leads to stimulation of the salivary glands and the beginning of the digestion process. The electrodes are pref. wedged between the teeth of the patient so as not to obstruct chewing. The galvanic current may be rendered even more effective by using e.g. citric acid. The invention may seem primitive, but could have special effect, and has been tested in different cases: it solves the problem of stimulating the appetite which is created because medicaments are not always compatible.
