Title: Dough apportioning machine for smooth and rough surfaced prods - chambered annular working cylinder replaced by simple transfer cylinder
Inventor: MUELLER HEINZ
IPC: A21C7/00
Filed: 1975-02-06
Abstract: The annular cylinder with radially extending workpiece chambers closed by the mantle of the core cylinder of a dough apportioning and working machine, with which it rotates on a horizontal axis, whilst an axial or circumferential motion is superimposed on their motion in the same direction, is replaced by an annular transfer cylinder. The transfer chambers of this cylinder are sealed inwardly by a sleeve so that there is no action on the lumps of dough moving with them towards the conveyor belt. The relative oscillating motion of the core and annular cylinders is allowed to continue without any action on the douth. Both smooth surfaced bread as well as angular, country-style bakery can therefore be produced on the same machine, without complicated adjustment of expensive mechanism.

Title: Multispindle automatic lathe bar feed and clamp - has spring loaded feeder and feeder jaw and clamping actuator
Inventor: LANGER DETLEF DR ING
IPC: B23B13/04
Filed: 1975-05-02
Abstract: The bar feed system is used for multispindle automatic lathes with horizontal indexable spindle drums. The clamping movement is carried out, before the spindle drum indexing starts, by a roller on a swining support which moves into two spindle positions and rests on a clamping slide. This arrangement reduces idle time on feeding and eliminates high forces due to bar impact on steps. The drum (1) with spindles (2) has feeder collets (21) directly behind clamping collets (4). Rollers (8, 9) rest on the support (10) which is actuated by the clamping slide (11). The feeder slide (14) slides, together with the clamping slide on shafts (12, 13). Max feed rate is achieved for about thirty degrees of indexing movement and retardation starts there. A sinusoidal movement generating cam ensures that the bar has slowed down at the end of the feed movement.

Title: Bearing lubricant dispenser supplying fixed surges - has heater coil producing pressure head in tube to open high speed valve
Inventor: MUENNICH HERMANN DIPL ING DR
IPC: F16N39/04
Filed: 1975-08-16
Abstract: The lubricant dispenser releases fixed amounts of oil to a bearing. The reservoir is surrounded by an electrical heating coil connected to a time switch. One end of the tubular reservoir is supplied from a tank through a non-return valve. At the other end of the lubricant reservoir tube is a pressure responsive high speed valve leading to a bearing supply tube. The lubricant passes through a spring-loaded piston under pressure, through the non-return valve, and into the tube. The heater coil is switched on by the time clock. The differential expansion of tube and oil produces an excessive pressure. At a limiting pressure, the high speed valve opens, releasing a fixed volume of oil which runs down to the bearing.
