Title: Moulding and packaging device for suppositories - with moulding plate and six detachable moulds forming one assembly for dispatch
IPC: A61J3/08
Filed: 1976-07-23
Abstract: Moulding and packaging device for suppositories and similar items consists of moulds made in two parts; one end is normally open to the orifice and the other receives a movable closing cap which can be detached when the suppository is used. The moules are supplied already mounted in a moulding plate. Two opposite edges of the plate have inclined edges and the other two sides have vertical edges and together form a dish into which the material to be moulded is poured. Excess of this material is removed by means of the levelling knife which is engaged at the inclined edge drawn across the base of the dish and withdrawn up the inclined edge so that the suppositories have a truly rectilinear base. A cover is placed over the plate; it engages in a groove and the assembly of six suppositories is thus obtd. ready for packing in a box for dispatch. The number of mfg. operations is considerably reduced as compared with previous methods and the filled detachable moulds are dispatched together with the moulding plate and its cover as one assembly.

Title: Inductively coupled binary lock - using key with code converted in VCO for transmission to FSK receiver and memory register with comparator
IPC: G07C9/00
Filed: 1977-02-18
Abstract: The inductively coupled binary lock system uses a key to transmit a series of binary signals with the use of a frequency modulated carrier wave to the lock. The key unit comprises a memory register which stores an alterable multiple bit key code. This key code is converted by a voltage controlled oscillator to a binary frequency shift keyed carrier. After amplification the carrier is transmitted from the key by magnetic induction to the lock. The lock unit comprises a receiving inductor and a frequency shift keying receiver which converts the frequency modulated carrier back to binary pulses of multiple bit data. This data is stored in a memory register where it is compared with a predetermined master code stored in a reprogrammable memory register.

Title: Multilayered mattress with ventilation and flexibility - has one-piece core layer with undulations providing articulated sections (OE 15.10.78)
IPC: A47C27/15
Filed: 1978-01-27
Abstract: The foam core of the mattress is designed as a stronger foam mat (10). It has transverse channels (11, 12) worked in symmetrically in the top and bottom surface so as to divide the core mat alternately strong support sections (17) and articulated sections (24). The mattress still retains its longitudinal flexibility and transverse stiffness whilst the inherent elasticity of the articulated areas prevents a permanent displacement of the support sections so that no empty spaces arise as in the case of known foam-filled mattresses. The one-piece core of the mattress is foamed in one step or cut out of a thicker foam block with the channels being formed at the same time.

IPC: G02F1/1337
Filed: 1978-03-08
Abstract: The moulds for homogeneous alignment of the liquid crystal and for the polarisation filters are produced simultaneously. To this end, a gel (3) of a dichroic dye having a concentration of from 1 to 30 % by weight is applied to the surface of plates (1) intended for contact with the liquid crystal. The gel (3) is then subjected to mechanical treatment to produce a film (4) from the gel (3), a speed gradient of from 10<2> to 10<7> s<-1> being maintained according to the thickness of the film to be produced, after which the solvent is removed from the film (4). The process is preferably intended for the production of liquid-crystal cells for watches and pocket calculators.
