Title: Glass crusher, for scrap glass bottles - has manually compressed spring to drive bottles against anvil inside crusher with collector bucket
Filed: 1980-11-26
Abstract: The crusher consists of a casing provided with a bucket in its lower part. Above the bucket is a trough located on the ends of a pair of levers. The levers are mounted on a horizontal pivot shaft and are fitted with a counterweight. The levers are moved to a horizontal position by a foot pedal, and are then near a swivel door. A bottle can be placed in the trough when the door is open. When the door is closed, a limit stop is released, so the energy of a spring and the counterweight swings the levers upwards through 90 deg. and the trough hits an anvil and breaks the bottle. The crushed glass then falls into the bucket.

Title: Mechanical locking mechanism for electrical lever switch - has system of articulated crank arms whose movement can be blocked by electromagnet armature
Inventor: MAINEULT JEAN
IPC: H01H3/30
Filed: 1981-07-01
Abstract: The turning axle (1) of the spring-assisted lever switch is linked, by a series of pivoting arms, to an electromagnet (14) whose moving armature can be used to block or free the switch. The axle turns a fraction of a circle in opening or closing the switch and the turning movement brings about the switch contact movement. A main pivoting arm (2) turns a crank (4) about an axle (5) running through the lower end of a balance arm (6) which pivots about an upper axis and moves against the action of a spring (16). A second set of crank arms (17,8) can also communicate during movement to the balance arm. One of the latter arms (10) has an inertia weight (12) at its end and moves against the force of a spring (11). A knee-joint pivot (9) has its freedom of movement determined by the electro-magnet armature when this is retracted, rotary movement of the whole assembly allows the balance arm to turn and likewise the main axle (1). The switch contacts are then opened.

Inventor: EILER ELEMER
IPC: A23L13/60
Filed: 1981-11-09
Abstract: The invention relates to a process and an apparatus for continuous filling and heat treatment of food masses, in particular meat masses, sausage preparations and the like. In this process, the raw mass is first charged at room temperature into dimensionally stable closed tubular moulds, the mould filled with air bubble-free raw mass is closed and the mould is then brought into a closed cooking space having a temperature of 75-85 DEG C. The moulds are moved there upwards and downwards in a paternoster-like manner and at the same time move progressively in the course of about 120 minutes through the cabinet, the mass situated in the moulds being heated to a core temperature of 70-75 DEG C. The products thus treated then pass into a closed preliminary cooling space of a temperature of 15-25 DEG C and are moved there for about 60 minutes in the same manner as in the cooking space and are thus precooled to a core temperature of about 42 DEG C. They then pass into a closed dry air cooling space of a temperature between -5 and -15 DEG C and are there moved for a period of 120 minutes again as in the cooking space and are cooled during this to a surface temperature of about 0 DEG C and a core temperature of about 10 DEG C. In the final section of the dry air cooling space, a balanced temperature of surface and core of the masses thus treated of about 4 to 8 DEG C is obtained. After the treatment, the mould is transported into an open space, the cover is removed and the dimensionally stable finished product is removed from the mould and delivered to further processing, for example slicing and packaging of the sausage product thus manufactured. The emptied moulds and the covers are then cleaned, complying with hygiene regulations, and supplied to renewed use.
