Title: Safety catch for paper cutting guillotine - has pawl engaging notches in in blade holder released via lever clamping sheet stack
IPC: B26D7/02
Filed: 1977-06-21
Abstract: A guillotine for cutting stacks of paper sheets has a blade (4) mounted on rollers which slide in inclined guides. The blade is held in its upper position by a pawl (15) which engages notches (23) cut in the end of the blade holder.

Title: Central heating summer control system - has sensors in hot water tank controlling heating system relays
Inventor: LIEBE FRIEDRICH ING GRAD
IPC: F24D19/10
Filed: 1977-12-01
Abstract: The central heating system includes a circuit for controlling a hot water tank (8) with provisions for winter and summer conditions. The operation of the burner (2), pump (3) and electromagnetic valve (4) for the hot water is controlled by a set of contacts operated by relays. Two relays are operated by an upper temperature sensor (12) and lower sensor (13) inside the tank. The relays close two upper contacts which are in series with the winding of a relay which operates the heating, and which has a holding contact for the two lower contacts. These latter two contacts are in parallel, and also in series with a contact which closes for summer operation. The first of the upper two contacts, which is operated by the upper temperature sensor (12) is bridged by a contact which is closed for winter operation.
Patent DE-2757958-A1 (DE)
Title: Plastic tank shell rim - mfd. in multipart mould with insert covered by elastomer
Inventor: SPEIDEL GEORG
Filed: 1977-12-24
Abstract: Plastic fluid container shells with a fork-shaped joint rim are mfd. by laying a glass fibre mat in an outer mould, inserting a mould element which determines the forked rim, and laying a second fibre mat on the not covered part. After applying the inner mould, the gap between the moulds is covered and liquid resin is admitted to the glass fibre filled spaces at a vacuum or pressure. This saves the manual forming of the template with resin impregnated glass fibres which exposes the workers for long periods to rising gas vapours.

Title: Luminous yield and brightness increase for kerosene lamp flame - uses preheating of combustion air for increase of flame temp.
Inventor: KAYSER-HEROLD UWE DIPL ING
IPC: F21V37/00
Filed: 1979-06-25
Abstract: The flame luminous yield and brightness of a kerosene lamp is increased by preheating the air delivered to the flame for combustion, thus increasing the flame temperature. Typically this air can be heated by the combustion gases in a heat exchanger formed by an encased tube of folded sheet metal. The heat exchanger and the flame are insulated by a glass cylinder, partly reflective and evacuated. The design increases the brightness of the lamp flame, without the need for pressure feed, or a mantle.
Patent DE-2928811-A1 (DE)
Title: Pushbutton dialling telephone - counts pulses sent from exchange and reduces speed by demanding opposite polarity for high digits
Inventor: DIRR JOSEF ING GRAD
IPC: H04M3/42
Filed: 1979-07-17
Abstract: A push button dialling telephone operates by counting pulses sent by the exchange and opening the loop on reaching the selected number. With 12 buttons, the required speed is reduced by only counting up to 6 and using one polarity for 1 to 6 and the opposite for 7 to 12. Pulses are detected by two opto-couplers, each in series with a diode but of opposite polarity. When a dialling button is pressed, one is connected across the line, which one depending on the digit. The exchange senses loop current and, if necessary, reverses polarity. The exchange then sends pulses which are counted at both ends, until the subscriber's counter opens the loop and holds it open until the button is released. The sequence then repeats when the next button is pressed.

Title: Regenerating mixed bed ion exchangers - with sepn. into exchanger types by reverse flow washing through inert interlayer and removing exchanger(s) to an external regenerator
Inventor: BRANDS HEINZ-JOSEF ING GRAD
IPC: B01J49/18
Filed: 1979-09-13
Abstract: Mixed bed ion exchangers are regenerated by sepg. the different exchanger types by back-washing through an interlayer of inert material, and removing at least one exchanger from the sepn. vessel. Process overcomes problems associated with previous regeneration process for mixed bed exchangers, in which the mixed bed is first sepd. by back-washing into a lower layer of the heavier cation exchanger and an upper layer of lighter anion exchanger.
