Priming liquid passes from a priming reservoir 15 via openings 23 into the impeller chamber 1 and is pumped into the discharge conduit 4. The conduit 4 is blocked by a valve flap 26, and the liquid is diverted via an opening 24 back to the reservoir 15 for recirculation. Separated air is discharged via an opening 25 leading into the discharge conduit 4 downstream of the valve flap 26. On completion of priming, the discharged liquid moves the valve flap 26 against the action of e.g. a spring into a position in which it closes the  opening 25.

Abstract: 1,100,716. Selective signalling systems. GENERAL ELECTRIC CO. 22 Nov., 1965 [9 Dec., 1964], No. 49474/65. Heading G4H. Various devices on a railway locomotive are selected for operation by transmitting a characteristic sequence of tone signals, the first of these being a safety tone without which none of the devices may be operated. The transmitter, Fig. 4, comprises a timing circuit 20 which first enables gate 62 to transmit the safety tone. Subsequently the timing circuit energizes in sequence two sets of manually actuated switches 75-84 which are connected to the appropriate oscillator gates 57-61. The receiver, Fig. 2 (not shown) comprises corresponding filters (34) tuned to the respective frequencies. The safety tone channel includes an output relay (STR) which closes a contact to supply power to line (51). The safety tone channel enables storage means (46) in the selection channels whereby reception of the two subsequent selection tones causes energization of the appropriate two relays (LFR), the contacts of these relays being so arranged that only the appropriate one of the devices (UD) is connected across the power supply through the closed contact of relay (STR).

Conversion to acid addition, organic amine quaternary, ammonium and metal salts may be carried out by normal methods using products containing a basic group at the 7-position or a free carboxylic group at the 4-position. In the case where a basic group is at the 7-position and a free carboxylic group is at the 4-position, an internal salt may be formed. In the above process it is possible, where necessary, to protect temporarily groups which do not participate in the reaction, e.g. OH, SH and NH 2  groups by acylation, tritylation or silylation and COOH groups by esterfication including silylation. Novel compounds of the first formula above and prepared by the above process may subsequently be modified to form other compounds within the said formula. Thus the examples describe the preparation of compounds by converting a 4- carboxylic ester group to the 4-carboxylic group, a 7#-acylamino group to the 7#-amino group, a 4-carboxylic group to a 4-carboxylic ester group. The starting materials for the above processes are prepared as disclosed in Specification 1,361,199.  Pharmaceutical compositions having antibiotic activity contain the novel compounds of the first formula above and a suitable carrier and may be in a form suitable for enteral, parenteral or topical administration.

Abstract: 1,067,060. Drilling and boring; machine tool details. CROSS CO. Nov. 26, 1965, No. 50411/65. Headings B3B and B3C. A machine tool having a tool slide (12) (Fig. 3, not shown) moving on a base (18) up to an adjustable stop (46) (Fig. 4, not shown) has a tool checking device (50) which gauges the effective length of a tool (24) before it is attached to the machining arbor (20) and simultaneously adjusts the stop (46) to the new tool so that repetitive machining accuracy, even after tool changes, is possible. The tool (24) is held in a support (48) and the checking device (50) lowered until a sensing element (56) registers a zero marking on the dial of the checking device. The checking device is lowered by a hand wheel (62) which advances or retracts a wedge shaft (68) and co-operating cam surfaces (112), (114), Fig. 7 (not shown), raise or lower shaft (60) to which the checking device is fixed. The wedge shaft (68) also has co-operating cam surfaces (124), (126) for simultaneously adjusting the stop (46) at the same time as the tool (24) is checked. Springs (102) and (118) are used to eliminate backlash. In the embodiment described the slide (12) is moved hydraulically and a valve (38) is used to slow down the slide movement from a fast traverse speed to a cutting feed speed. The position when this slow down occurs is also related to the gauged length of a new tool by incorporation of further cam surfaces (148), (146) on the wedge shaft (68) to adjust the position of an element (128) which is pivoted downwards to operate a valve stem (40) by a travelling dog (42) on the slide (12).
