Title: Pivoting automatically retracting pelmet - has inverted L-section with magnetic holding catch and is moved by head of side-hung opening window light
IPC: A47H2/00
Filed: 1976-02-20
Abstract: The auto retracting pelmet (2, 3) is designed for installation where there is insufficient space between the window frame and the ceiling for a fixed pelmet. It is pivoted into the retracted position by the head of a side hung opening light (6) as it pivots open. The pelmet is of inverted 'L' section with lateral end walls and mounted on a butt hinge (11,13) so as to pivot about a horizontal axis (9). The axis of rotation (9) is in the ceiling plane, parallel to the window opening and offset inside the room relative to the vertical pelmet panel (2). A magnetic contact lock may be used to hold the pelmet closed and retraction rotation is initiated by the leading corner (A) of the frame (6) or the opening light.
Patent FR-2344298-A1 (FR)
Title: Precise control of drip feed for medical perfusion etc. - uses electromagnet to actuate two tube compression valve clamps
IPC: A61M5/168
Filed: 1976-03-16
Abstract: A gravity, dpip-feed is claimed for liq. perfusion or injection into a patient's body via a flexible tube from a supply flask above the body. The tube passes through a first valve which normally closes the tube by compressing it between one fixed and one movable jaw, but is periodically opened by releasing the movable jaw. A second valve, between the first valve and the injection point, again has fixed and movable jaws which can at least partly, and pref. completely close the tube by compression. The two valves pref. open simultaneously. The second valve closes the tube completely, but does not start to close until the first valve is completely closed. The movable jaw of the first valve is pref. tapered to a narrow, leading edge, the movable jaw of the second valve pref. has a comparatively large area or jaw face. Both movable jaws are pref. fixed on a single, mobile carrier frame actuated by an electromagnet. The electromagnet is pref. of the twin-pole type and is used to pivot the carrier frame on which the mobile jaws are mounted. Used for controlling the rate of drip feed e.g. in gynaecology and cardiology cases. Combines the precision of the peristaltic pump with the cheapness of gravity drip feed. No air can enter the patient via the needle. The drip base can be precisely and positively controlled, even below 20 drips per minute.

Title: DC motor thyristor control system - permits supply level to be reduced to near zero using auxiliary thyristor
IPC: H02M3/135
Filed: 1976-07-05
Abstract: A DC Supply control is esp used for regulating the speed of a motor. It uses main (Th1) and auxiliary (Th3) thyristors which allow the power supply level to be reduced to a value close to zero and the duration of each current excursion from zero to be varied. The main switching thyristor is in parallel with an extinction thyristor itself in series with an inductance and capacitor, the total circuit including a parallel starter diode. An auxiliary thyristor (Th3) is connected in series with the thyristor (Th2) controlling extinction and is triggered at the same frequency. Alternative arrangements allow this auxiliary thyristor to be mounted in series with that controlling the main switching line.

Title: Liq. detergent for heavy wash, contg. nonionic and anionic surfactant - using alkylbenzene sulphonate and fatty acid soap in specified ratio as anionic surfactant
Inventor: SIKLOSSY ISTVAN
IPC: C11D10/04
Filed: 1976-08-12
Abstract: The compsn. contains (a) 28-44 wt.% nonionic surfactant prepd. by condensing 4-11 moles ethylene oxide with 1 mole 13-16C alcohol, and (b) an anionic surfactant, in ration by wt. (a):(b) in free acid form of 1-2. 3:1 (1.3-2:1). The anionic surfactant contains (I) an alkylbenzene sulphonate with a 9-15C alkyl gp., and (II) 0.2-5 (1.5-5) wt.% of a soap of a 16-24C (18-24C) satd. fatty acid. The cations of I and II are derived from mono- or tri-ethanolamine, K and/or Na. In (b) the ratio by wt. of the acid form of I to the acid form of II is 3-80:1 (4-70:1); opt. this ratio may be 3-10:1 (4-8:1). The compsn. is used to wash large domestic articles, and is stable on storage, even after freezing, and is low-foaming. It has good action, both as a pre-treatment agent, e.g. for removing spots, and as a wash-bath, e.g. in concn. 0.2-0.6 (0.3-0.5). It is more effective in removing spots from polyamide, polyester, or polyester/cotton mixts. As (a), an adduct from 6-9 moles ethylene oxide (EO) and a 14-15C alcohol is pref. In (bI), the alkyl gp. is pref. straight-chain 12C. As (bII), soaps from natural or synthetic fatty acids may be used. In an example, a compsn. contains an adduct from 7 moles EO and a 14-15C alcohol, a 11-12C alkylbenzene sulphonic acid, a 12-22C fatty acid mixt., triethanolamine, KOH, ethanol, a brightener and water.

Patent FR-2365040-A1 (FR)
Title: Self-activated engine with rotary output - uses unbalanced pivoted weights on rotor to provide continuous turning force
IPC: F03G7/10
Filed: 1976-09-20
Abstract: Two circular discs (1) are fixed to an output shaft (2) running axially through their centres. An even number of masses (8) is held between them in a symmetrical arrangement round the perimeter. Each mass has a shaft (4) which runs through the discs and carries rollers (7) on its ends. The rollers run on profiled support rails (6, 5) adjacent to the lower part of the main circular discs (1). The support rails take the weight of the masses at this part of the circumference and thus unbalance the forces on the circular discs. The unbalanced forces then produce rotation of the discs with a resulting useful output.

Title: Semi-automatic vehicle wheel chocking system - moves chocks inwards to fix wheel or rim through shaft drive
IPC: B60P3/073
Filed: 1976-11-29
Abstract: A system of semi automatic chocking of vehicle wheels, is operated from the driving position. The chocking of the wheels is obtained by two side shoes (1, 2) which are incurved to press on the lower part of the wheel, or rim. The chocks are applied by a cam or lever (3) controlled by a shaft (4) acting in a screw and nut manner. This shaft is driven through a friction clutch (6) and bevel wheel (9) driven by another bevel wheel (8). The chocks, instead of being curved, may be wedge shaped. The system can be applied to wheels having different track widths and the first bevel wheel can be hand or power driven.

Title: Swinging supporting wheel for rotary plough - has wheel support extending obliquely downwards in working position
IPC: A01B3/42
Filed: 1976-12-01
Abstract: A swinging supporting wheel for a rotary plough has a wheel support (7) mounted on a horizontal transverse shaft of the plough frame (16). It extends obliquely downwards in the working position, abutting against a stop (24) of the plough frame. When the plough frame is raised, the wheel support is moved by force of gravity into a vertical position, and when the plough frame revolves it is pivotted first forwards then into the opposite vertical position. On encountering the ground, the wheel support is prevented from swinging back through a vertical position to a forward position by a device which automatically releases the support when the plough frame is lifted or rotated.
