Title: Meat roll press - with pneumatic cylinder reciprocating upper of two semi-cylindrical shells
Inventor: TENNINGER ANNELIESE
IPC: A22C7/00
Filed: 1978-06-08
Abstract: Irregular pieces of meat are prepd. by deforming them to the regular cylindrical shape needed for rolls of smoked ham. A pneumatic press actuates the upper of two semi-cylindrical shells while the piece of meat is moved axially and turned by hand. The normally conical piece of raw meat is held at both ends by two hands, as the pneumatic press cylinder is reciprocated at a rate which is adjustable by a throttle valve. This does not change the structure of the first-class meat and causes no scrap. Rolls of uniformly high quality are turned out in a continuous process.

Title: Patterned fabric stacker - has lamps for positioning and pedal linkage to operate lower securing needles (OE 15.4.79)
Inventor: HALBWIRTH FRIEDRICH
IPC: A41H43/02
Filed: 1979-03-06
Abstract: The equipment to stack patterned fabric, so that the patterns lie exactly over each other, has two small lamps mounted above the slitted plate. The lamps can slide against each other so that the light cross falls on the fabric to match the required pattern marking points. The points of the needles lie under the plate supporting the fabric. A pedal and linkage provides a stepless lifting action to the needles to bring them to points on the fabric outside the pattern marking points. Above the fabric there are pressing arms with pressing surfaces and recesses to press the material against the projecting needles. The needles and the pressure arms are moved in succession and synchronously. The mechanism allows the fabrics to be stacked so that their patterns are correctly positioned, without exposing the operative to any hazard from the needles, and without damaging the pattern of the material.

Title: Plastics profile butt welding - involves applying recessed groove along joints to absorb upsetting flash
IPC: E06B3/96
Filed: 1979-06-13
Abstract: Hollow plastic profiles are fabricated into frame structures, e.g. for doors and windows, by butt welding at the mitres. An allowance must be made for the upsetting length when the sections are cut before the application of heat and pressure to perform the butt joint. All walls of the profiles which are visible when the frame has been installed are provided with a stepped recess along the proposed joint. The dimensions of the recesses are designed to compensate for the volume, displaced by the upsetting operation. The pref. method of producing the recesses is milling in one machining operation with the cutting operation.

IPC: C07D521/00
Filed: 1979-11-03
Abstract: Triazolylvinyl ketone derivs. cpds. of formula (I) their physiologically tolerable acid addn. salts and metal complexes are new. R1 is opt. substd. alkyl or opt. substd. phenyl; and R2 is haloalkyl, haloalkenyl or alkoxycarbonyl.

Title: Flue gas concentration determn. - using extra light chopper and band-pass filter in receiver
Inventor: STOELZL GERHARD
IPC: G01N21/53
Filed: 1979-11-12
Abstract: The concn. of the components of a flue gas mixt. contg. various gases and also smoke particles is determined by measuring the optical radiation which has passed through the mixture and has been reflected back through it to a photoelectric transducer. A light chopper (electro-optical modulator, rotating chopper disc, rotary prism) is arranged between the measuring space and the reflector. The receiver includes at least one selective band- pass filter for the suppression of any d.c. voltage components. This prevents erroneous readings by the light which is back scattered in the measuring space, and restricts the measurement to the light reflected by the reflector.

Title: Controlling workpiece processing by programmed NC machine - using program memory with variable program and sub-program regions
Inventor: EBERT RAINER DIPL ING
IPC: G05B19/414
Filed: 1980-07-28
Abstract: The control arrangement for programmed processing of a workpiece by a numerically controlled machine is esp. for processing using subprograms with one or more workpiece program stores each contg. a program for a workpiece. Each call to a subprogram is detected by a decoder and multiple processing achieved using a counter. Programming economy and optimum program memory usage are achieved. The circuitry required to access the subprograms is minimal. This is achieved by dividing the workpiece program memory into a variable region for the workpiece program and a variable region for subprograms. Repetitive operation of a partic. subprogram is achieved with a single transfer of the subprogram into the subprogram region of a workpiece program memory, thus facilitating programming.
