Patent FR-2245526-A1 (FR)
Title: Carton loading machine with items - has grating with items aligned above and carton below
IPC: B65B39/00
Filed: 1973-10-01
Abstract: The machine is particularly for filling cartons with bottles, and has a grating above which the items are aligned in rows by a first mechanism. A second mechanism aligns a carton underneath the grating, which has a series of oblong bodies, the intervals between which are such as to allow the items to slide between them. Guide bodies are mounted at intervals along the oblong bodies, forming square-section passages for the items, and consists of rigid arms extending downwards, pivoting on the oblong bodies at the passage corners. The arms extend towards the centres of the passages, swinging towards the corners of the latter as the items pass through.

Title: Ultrasonic display system for human body organs - sequentially activates two groups of piezoelectric elements
IPC: A61B8/00
Filed: 1973-12-19
Abstract: The internal organs of the human body are observed on an oscilloscope. The ultrasonic sweeps are advanced in small steps under electronic control to give an almost continuous echograph. A piezoelectric linear assembly (21) has a number of metallised bands (23) on one face (22) while the opposite face (24) is connected to earth. These bands are connected by conductors (25) to an electronic logic control unit (26). The bands are also connected by conductors (27) to a second logic control unit (28). Both units are controlled by a common unit (29). During time periods the first control unit (26) causes the piezo-electric elements to transmit and then the second control unit (28) connects these elements to the receiver. By coding these control units the number of elements used can be adjusted.

Title: Trough conveyor suspended from support cables - height adjustment one side, for bends or curves
IPC: B65G39/14
Filed: 1974-06-04
Abstract: The belt (5) of a troughed conveyor is carried on sets of rollers (1) spaced along the track and supported by cables each side. Each set has a central roller (3) and one each side (2, 4), these latter being angled upwards to form the trough. They are connected together by universal joints (10), turning as one, and run in bearings (6, 7) which, in turn, are suspended from the support cables (8, 9). To negotiate a bend or curve, the support cable (9) on the inside may be lowered a calculated distance (h) below the outside cable (8). Alternatively, each side roller on the inside may be shorter in length, the cables remaining at the same height.
Patent FR-2286605-A1 (FR)
Title: Treating and maturing anchovies - to reduce handling costs and hasten removal of fat
IPC: A23B4/023
Filed: 1974-10-04
Abstract: Anchovies are treated and matured by a process in which the fish is placed directly into barrels or tanks, without removing the heads or without preliminary evisceration, after having been mixed mechanically with salt in 500-1000 g of salt per kg of treated fish. The fish is salted in bulk and subjected to a pressure of 80-100 kg per 300-350 kg barrels. On the second day the level of the fish will have fallen, under the effect of the pressure and the serum, blood and salt mixt. which floats is collected. The barrels are then topped up with a new layer of fresh salted fish; this in turn, after 24 hours, allows more serum to be collected. On the third day a third layer of salted fish is added under the same conditions and the liberated serum collected as before. From the third day onwards the barrels are "watered" with the decanted serum/salt mixture so as to remove the fat from the fish; being lighter it rises to the surface and flows out of the barrel. When all the fat has been removed, the fish is watered every 8-10 days with fresh brine warmed to 15-20 degrees C, according to the ambient temp. until maturing is complete. This may take 3-4 months instead of the 12-18 months needed for the conventional process. The considerable redn. in the maturing time allows large stocks of anchovies off the French central Atlantic coast to be exploited competitively. Both the handling costs and the loss in wt., because of too long a period in brine under pressure, are reduced.

Title: Direction control for DC series machine - uses thyristor switching of armature current and braking resistors
Inventor: PHAM QUANG MINH
IPC: H02P7/28
Filed: 1975-02-07
Abstract: The principal control for this DC series motor is a thyristor (H) which has a chopping-rate determined by a logic unit (E). The current flow in the armature is switched by four thyristors (T1-T4). These are arranged so that if one pair (T1, T4) is gated on, then current flows in one sense relative to the field winding and conversely with the other pair (T2, T3). Braking resistors (RF1, 2) are connected across the armature in series with diodes. A diode (DR) is connected in opposition to the chopping-thyristor to accept motor current in 'off' periods. This system of switching overcomes the problems of mechanical switching of the armature current and is applicable to traction motors.
