Abstract: The receptacle (112) is formed of a floor (116) and four walls which extend from the latter and of which two opposite walls are transparent, flat and parallel to one another and have a predetermined spacing from one another. The other two side walls (119) possess a smaller spacing from one another, so that between the four side walls a space is formed with a narrow, rectangular cross-section to receive a small quantity of liquid. The two more closely compacted side walls (119) carry at their external surfaces two respective ribs, which extend parallel to the other two transparent side walls. The outer edges of these ribs are connected to one another by walls to form a respective receiving pocket (117) for the limbs of a U-shaped heat-conducting body to be inserted from below. Each one of these two walls is penetrated by a narrow slit (120), which extends in a vertical direction from the lower end of the receptacle to the vicinity of the upper end of the pocket (117) and is narrow in comparison with the width of the wall. <IMAGE>

Abstract: A card index device, in particular an alphabetical telephone index, consisting of a housing and a drawer which is pushed into said housing and springs out automatically with the desired index card lying at the top of a pile after depression of one of the selection levers projecting with its operating end through holes in the front part of the housing and release, thereby effected, of a latching mechanism under the effect of a spring, in which drawer carriers are arranged for the index cards. With a card index device of this type, the intention is that, with relatively simple means, the index card lying at the top, with the drawer automatically springing out of the housing after depression of a selection key, is guided out securely and lying flat by carriers in the drawer, that it can be read and, if appropriate, can be exchanged in a simple manner for a new card. The object is achieved by a row of selection levers (7) which are mounted in a swivelling manner centrally in the housing (2), of which levers the end (9) opposite the operating end (6) is constructed so as to be hooked, so as to raise the pile of cards lying above the desired card (4) when pressure is applied to the operating end (6), so as to introduce the pile of cards with the holes (12) provided at the end portion of the cards (4) into teeth (13) which hang down from the lid of the housing (2) and penetrate a hole (14) in the selection lever (7), and so as to release the latching mechanism (17, 18, 19) which holds the drawer (3) in the housing (2). <IMAGE>

Abstract: A process and apparatus for making alkali cellulose having a desired predetermined degree of polymerisation in which cellulose is steeped in an alkali hydroxide bath, generally 17-25% sodium hydroxide, and then passed through an RF treatment chamber where it is subjected to an RF energy field, to produce a controlled depolymerisation thereof. Upon emergence from the steeping bath, the cellulose passes to an excess solution removing means, such as one or a series of pairs of nip rolls where the excess solution is expressed from the cellulose and the amount of absorbed alkali is controlled. Preferably, the excess solution is recovered and returned to the steeping baths. A second, lower concentration, steep bath may follow the RF treatment chamber.

Abstract: Disclosed is a portable continuous infusion apparatus for administering an injectable liquid to a patient. The apparatus expells the contents of a syringe on a time controlled basis. It employs two separate springs, with one spring used to power a clockwork and another spring to power a gear rack to advance the syringe plunger or piston. Opening and shutting the apparatus cover automatically winds both springs simultaneously. A safety prevents closing the cover unless the springs are wound. Advancement of the gear rack is adjustable by a control which acts on an escapement lever which regulates an escape wheel. The control moves the escapement lever axially so it can engage a different number of wings on the escape wheel, thereby regulating the incremental advance of the gear rack acting on the syringe plunger.

Abstract: In a process for producing cement-bonded shaped articles wherein a mixture is prepared from cement, aggregates and water and the mixture is made to set and harden, the mixture has added to it an alkyl compound having an oxygen- and sulphur-containing functional group or, if it is the alkyl compound of an acid, a water-soluble metal salt of such an acid in an amount of from 0.5 to 1% by weight of the cement used. The preferred alkyl compound is an alkylsulphonamidocarboxylic acid of from 8 to 18 carbon atoms, in particular 12 carbon atoms, in the alkyl chain. The process makes it possible to use cement having a very fine grain fraction and also to work with a large excess of water. More particularly, fibrous materials resembling asbestos cement can be produced using other fibre materials.

Abstract: A complementary bipolar transistor circuit having the same output impedance for positive and negative input voltage transitions and very low standby power consumption. A first pair of complementary bipolar transistors (1, 2) connected in emitter follower configuration is driven by a second pair of complementary transistors (5, 6). The collectors of the second pair (5, 6) provide signals (via lines 7, 8) to the bases of the first pair (1, 2). The signals have d.c. levels offset from each other with each signal level being substantially at the value which switches the respective transistor of the first pair (1, 2) on and off. The excursion of each signal is only a fraction of the voltage V be  necessary to forward bias each emitter-base junction of the first pair of transistors (1, 2). 
     In a driver circuit species of the invention (fig. 1), the bases of the second pair of transistors (5, 6) are connected to each other and receive the input driving signal (at 9). In a NOR logic circuit species of the invention (fig. 2), the emitter of one transistor (18) of the second pair of transistors (18, 19) is connected (via line 21) to the base of the other transistor (19) of the second pair of transistors and receives one of the input logic signals (e.g. at 20). Additional transistors (22, 23) are connected in parallel with said one transistor (18) of the second pair of transistors (18, 19), the bases of the additional transistors receiving the remaining input logic signals (at 24, 25). The ouput from both the driver circuit and the logic circuit is derived from the commonly connected emitters of the first pair of transistors (1, 2 resp. 15, 16).

Abstract: In a SECAM-PAL transcoder, color-difference signals, sequentially recovered from received SECAM signals by a single FM discriminator (15), are supplied via a first emitter-follower (30) to a first modulating signal input terminal (M) of a balanced modulator (35), which develops a quasi-PAL signal output using PAL subcarrier frequency oscillations applied in push-pull at carrier terminals (C, C) thereof. A DC potential, supplied to a second modulating signal input terminal (M') of the modulator via a second emitter-follower (70), matches discriminator output level under no-color signal conditions. Third and fourth emitter-followers (90, 100), responsive to a blanking waveform (BL), effects cutoff of the first and second emitter-followers (30, 70) during blanking periods and delivers an elevated planking pedestal to the first terminal (M) and a matching blanking pedestal to the second terminal (M'). During a portion of the blanking period, a burst gating pulse (BG) supplied via the third emitter-follower (90) causes departure from the blanking pedestal level at the first terminal (M) without disturbing the blanking pedestal level at the second terminal (M') to develop a burst component of controlled magnitude in the quasi-PAL signal output from the modulator (35).
