Title: Frame mitre jointing tool - consolidates angled joints of bar sections by sideways movement of indenting punches
Inventor: VEGA MANUEL PRIEGO
IPC: B21D53/74
Filed: 1975-03-13
Abstract: The two mitred frame sections (47, 48) are fitted with a corner filler (50) and held between a corner post (11) and a clamping plate (22). The corner filler has grooves (51) into which the frame sections are depressed by punches (12). Punch holders (14) move longitudinally in guides (15) and with sideways movement (S) induced by the offset (V) between the punch point (20) line (12a) and the thrust line through the pivot (19). The punch-holder is spring-loaded with plate springs (16) which compress during indentation. A toggle-linkage operates the clamping plate (22). Pneumatic sensors (55) detect for correct seating of the sections against the corner post.

Title: Self loading timber freighter - with flooding holds and rear opening doors to receive bundles floated in
Inventor: LUNDBAECK PER BJARNE
IPC: B63B25/00
Filed: 1975-04-05
Abstract: The ship is divided into long, parallel holds separated by vertical bulkheads. The holds are accessible by rear doors on the stern and the ship can be ballasted to sit lower in the water. Long lengths of timber bundles can be floated into positions in the holds, aided by winches at the front of the holds. Folding floor sections divide the holds into smaller compartment to achieve vertical stacking density, with each layer loaded by raising the ship slowly out of the water. The separate compartments prevent the cargo rolling about and thus provide a well trimmed ship. The ship is unloaded in the same way if required, and thus eliminates costly lifting gear.

Title: Mixer gate device for filling moulds with polyurethane - has a constant width for most of its length and a number of alternate cross-sectional increases and reductions
Inventor: KLEPEK GEORG ING GRAD
IPC: B29C67/24
Filed: 1975-10-06
Abstract: Device for filling a pressurised polyurethane mixt. which has been compounded in a mixing head, from this mixing head to a mould cavity, features a sprue whose end nearest the mixing head has a circular cross-section whilst that end nearest the mould cavity has a slot-shaped cross-section. The sprue is of constant width over major part of its length, and has several successive alternating, abrupt cross-sectional widenings and constrictions. Device can be used in mfr. of polyurethane foam mouldings. Rapid feed rate of reaction mixt. into the mould is facilitated hence correspondingly rapid release cycles are obtd. for the resulting mouldings. The reaction mixt. is fed into the mould cavity without generation of "eddies" and turbulences which might result in inhomogeneous foam moulding with flawed surfaces.

Title: Stacked plate solar heat absorber - fluid passes through sheets to form heat transfer contact with sun-radiated plate
Inventor: ANTONIOLI VITTORIO
IPC: F24S10/50
Filed: 1975-10-17
Abstract: Solar heat absorber constitutes a stack of plates involving sheet walls (1, 1') through which water or similar diathermal fluid is passed in such a way that the upper stack plate exposed to the direct sunlight enters heat-transfer contact with the fluid, right across the inside surface of the plate. Preferably the lower wall is flat, as compared with the upper wall (1) which is corrugated with the result that the rays of morning and evening sun are repeatedly reflected between the corrugations and progressively absorbed, so that the absorption capacity of the collector reaches 100% black body efficiency. The absorber should be enclosed by a frame (2) made from wooden supports (3) and insulating walls (4) in the lower part, with a glass pane (7) at the top.
Patent DE-2554986-A1 (DE)
Title: Bellows type differential pressure meter - has all mechanical linkages outside pressure chambers avoiding contact with medium
Inventor: METZGER REINHOLD
IPC: G01L7/06
Filed: 1975-12-06
Abstract: The differential pressure meter consists of two bellows mounted one above the other between a base plate (1) and clamping plate (5) within the instrument housing. The central division between the chambers carries a collar and transmission rods (18) set at 120 deg. intervals. These rods pass through the clamp plate to operate a linkage (14)(22). This in turn operates the pointer mechanism. The positive pressure coupling (7) is connected directly to the base of the first pressure bellows. The negative pressure coupling (8) is connected to a line (25) which terminates in the upper plate. A channel leads to the upper chamber. The instrument may indicate absolute pressure if the negative pressure chamber is evacuated and pressure applied only to the first chamber. No part of the transmission linkage comes into contact with the pressurised medium, thus the use of special, corrosion-proof materials is unnecessary.

Title: Pallet unloading unit with flexible grating - uses grating to move layer of goods onto neighbouring transverse conveyer
Inventor: UNGERER HANS-JOACHIM
IPC: B65G59/02
Filed: 1975-12-10

In order to achieve this a flexible grating (8) is used to move over the topmost layer (5) with the aid of a following projection (9). The latter is positioned between the layer held by the grippers (6) and the usual pallet load (4). The following projection used to engage with the sides of the goods layer is preferably a cylindrical rod which swivels against the action of a spring located in a space formed by omitting a rod from the grating.

IPC: C07D501/60
Filed: 1975-12-16
Abstract: 7-Amino-desacetoxycephalosporanic acid is prepd. by treating acetoxymethyl esters of cephalosporins of formula (I): (where R is an acyl gp. present in natural penicillins, esp. from phenyl -acetic acid or phenoxy-acetic acid), dissolved in an org. solvent, e.g. benzene, with an excess of PCl5 and pyridine or other t-base then with an alcohol, esp. methanol, and water, the prod. crystallising at a pH of 4-4.5. Method avoids a multi-stage process from penicillins which gives only a final yield of 25-30% overall. The yield of this process is over 45%.

Title: Protective circuit for hazard flashers - with holding relay operated from ignition switch to prevent battery drain
Inventor: LEITNER FRIEDRICH
IPC: B60Q1/52
Filed: 1976-02-05
Abstract: The hazard warning flashers are operated by a control switch (14) in which the supply input is linked to a holding relay (8) operated from the ignition switch. The flashers are switched on with the ignition on, after which the ignition can be switched off leaving the flashers operating. The system is designed for open vehicles to prevent a thief from driving off, when the vehicle has been left with the flashers on. Operating the direction flasher switch has no effect when the warning flashers are on, thus preventing damage to the circuit. The warning flashers are cancelled either by operating the switch, after which they can be switched on again, or by switching on the ignition, when the holding relay drops out.
Patent DE-2613342-A1 (DE)
Title: Mechanical pulse force generator - has threaded disc controlling reciprocating weights to ensure fast advance and slow return motions
Inventor: KRANICH MANFRED
IPC: F03G3/00
Filed: 1976-03-29
Abstract: The pulse generator uses the inertia of several masses which are thrust against the flank of the thread (1) in the disc driven by a motor. The rate of rise of the weights (2) is determined by the thread helix angle and the rate of rotation and is slow compared to the rapid return under the action of the springs which press the weights. The impulse of the propelled unit results in a forward displacement with backward motion hindered by the resistance of friction.

Title: Vehicle tyre pressure warning device - has lever connecting sensing device to brush which contacts plate on brake housing to actuate warning light
Inventor: GOETZ HANS DIPL ING
IPC: B60C23/04
Filed: 1976-11-26
Abstract: The tyre pressure warning device gives an indication to the driver of a vehicle when the pressure falls below a critical value. A tube (4) connects the tyre to a pressure sensing element such as a diaphragm or a piston (2), which either alone or in conjunction with a return spring (7) provides an indication of tyre pressure by virtue of its position. The sensing element is coupled to a lever arrangement (11-13) carrying an electrical contact brush (12) which may be of copper. At a critical tyre pressure, the movement of the piston (6) transmitted to the lever is sufficient to bring the brush into contact with a plate (15) on the brake mounting, completing an electrical circuit and causing an indicator lamp in the driver's cab to light up.
